Latest / HER / The A-Z on Intermittent Fasting
Transcript
- 0:08Pam Peeke, MD: Hi, I am Dr.
- 0:08Pam Peak, and This is episode number 548 of the Bold And the Brave.
- 0:17Her podcast.
- 0:20today I'm joined by a repeat offender.
- 0:23That's right, Dr.
- 0:24Susan Kleiner is back again.
- 0:27Absolutely.
- 0:28There she is with her little heart and everything and she
- 0:31is absolutely extraordinary.
- 0:33The owner and founder of High Performance Nutrition, uh, with PhD in an RD and every
- 0:41single kind of education and academic standing you can in the nutrition world.
- 0:48Um, and she has written countless books, And the latest one was The Good Mood Diet,
- 0:54feel Great while you drop that weight.
- 0:57Oh no.
- 0:57That wasn't meant to really rhyme, was it?
- 1:00It was.
- 1:01Okay.
- 1:01I get it.
- 1:02I get it.
- 1:03Anyway, so Dr.
- 1:05Susan Kleiner, welcome back to the Herb Podcast.
- 1:09Susan M. Kleiner, PhD:
- 1:09you so much Dr.
- 1:10Pam.
- 1:11I am thrilled to have, be a returning guest or a repeat offender, however.
- 1:18Pam Peeke, MD: I kind of like repeat offender.
- 1:20I don't know, maybe I have like some law enforcement in my blood somewhere.
- 1:24Susan M. Kleiner, PhD:
- 1:24I think it's just the rebellion in you.
- 1:27Pam Peeke, MD: You know something, you are absolutely correct.
- 1:30You know, you always nail it, Sue.
- 1:33I'm just saying.
- 1:34So here's the deal.
- 1:36Here we are at the beginning of a new year.
- 1:402026 and you know what's on everyone's damn mind.
- 1:46And That is, their number one thing is health.
- 1:49and usually health is translated into weight.
- 1:53because, the majority of Americans, I'm only gonna stick with Americans
- 1:59right now, the majority of Americans, are at least overweight.
- 2:05Okay.
- 2:05At least overweight.
- 2:06And they've been that way.
- 2:08since 1996.
- 2:09Quite frankly.
- 2:10We've had a majority of people, of course, overweight then
- 2:13was like five or 10 pounds.
- 2:15Now it's more like 30.
- 2:16And then we have, and women are worse than men.
- 2:20a greater percentage of obesity out there in women.
- 2:26Gotta say we're in the forties, right?
- 2:2940%.
- 2:30So we've got all kinds of things going on.
- 2:33And then we also have the GLP type medications floating around.
- 2:39the, announcement about Wago v.
- 2:43from Novo Nordisk, coming out in tablet form now, and basically
- 2:47oral form just hit the news.
- 2:50And so now we've suddenly got all kinds of interesting options out there.
- 2:56and people are sitting there saying, okay, what am I supposed to do?
- 3:00And.
- 3:02Talk to me about this whole issue of intermittent fasting since it's
- 3:08everywhere and people are talking about it all the time, and what's going
- 3:14to end up working well for people.
- 3:17that's a huge mouthful of wild and crazy stuff.
- 3:21But what I'm saying quite frankly, is that the world has become more complex.
- 3:27Okay?
- 3:28Now I'm gonna ask you, Sue, right?
- 3:30in the years past.
- 3:32Don't people write about this time of year?
- 3:34Say, uh, I gotta do a diet.
- 3:37Okay, so what's your thought now?
- 3:41Susan M. Kleiner, PhD:
- 3:41Well, now hopefully it's at least diet and exercise and maybe we
- 3:46have, we, we've had an impact.
- 3:48I know my gym is packed right now, and I love to see that.
- 3:53Although, I have to say in the weight room, I still am one of
- 3:57very few women, and girls that.
- 4:01spend time in there, although I have to say all those young dudes no longer ask
- 4:06me if I'm actually using the rack, if I'm standing by it with weights on the bar,
- 4:12it means I'm really using that racks.
- 4:14Pam Peeke, MD: I love that, that's such a great anecdote.
- 4:17I just, you know, are you really using that?
- 4:19No, I'm just standing here like a moron staring at the wall.
- 4:24What do you think I'm doing?
- 4:25You know, if you were standing here, what do you.
- 4:28I, I wouldn't even ask you.
- 4:29Obviously you're using the rack.
- 4:31Susan M. Kleiner, PhD:
- 4:31know.
- 4:32So, but I mean, I am, I'm always looking at the bright side And so I,
- 4:38along with the idea of diet, food restriction and weight loss, I
- 4:44think that the exercise message is beginning to hit home for more people.
- 4:51And I think that the concept of weight loss.
- 4:55Is beginning to overlap, at least with health and fitness and lifespan and health
- 5:03span, meaning that you can enhance the quality of your life over the years that
- 5:11you have by eating well and exercising.
- 5:15However, there is no doubt that when we start out the year.
- 5:21If you pick up a magazine, if you open your laptop, if you look on
- 5:26your phone, if you're scrolling in social media, what you're going to
- 5:31see are as many weight loss plans as there are, I think, stars in the sky.
- 5:38So how do we know number one.
- 5:43How should we eat to be healthy and promote a lifestyle that we want and
- 5:50support our exercise that we wanna do?
- 5:52And the other is this alphabet soup of drugs available to us now
- 5:58to help control how much we eat.
- 6:02Not what we eat necessarily, but how much we eat and how hungry we are.
- 6:08All of This is kind of converging at this time of year to the concept, as
- 6:15you said, of either, we think of it as intermittent fasting or time-limited.
- 6:21Time-restricted eating.
- 6:23You'll see both terms.
- 6:25You'll see if f and TRE, we just love this alphabet soup, but it's the same thing.
- 6:32Time restricted eating, intermittent fasting, and it overlaps
- 6:36really with the GLP one drugs.
- 6:39And so how do we, find our way through the forest?
- 6:44Pam Peeke, MD: Oh, I'm gonna put something out there for you.
- 6:46Sue.
- 6:47I really want to hear what you have to say about this.
- 6:51Okay.
- 6:52So This is Dr.
- 6:53Peak's take on the whole damn thing.
- 6:55Let's just cut right to the quick.
- 6:58Okay.
- 6:59We're not gonna sit here and do, like now, now we're gonna talk about
- 7:0216 hours of fa No, I'm gonna tell you One of the things I found after
- 7:10I met an extraordinary scientist, Dr.
- 7:13Sachin Panda at the Salk Institute, who became a good friend, was
- 7:20the whole issue of honoring.
- 7:23The clock.
- 7:24Okay, so I'm all about circadian rhythm.
- 7:30In other words, let's just go back to cave woman days.
- 7:34And I gotta say, I've always used this analogy and I just had on the show.
- 7:40Dr.
- 7:40Marian Nessel, one of the greatest names in, nutrition science.
- 7:45She and I are both, Berkeley grads she's a trip and a half, and of course she just
- 7:50published her new book, what to Eat Now,
- 7:53which
- 7:54Susan M. Kleiner, PhD:
- 7:54like this.
- 7:55Pam Peeke, MD: Yeah.
- 7:55I, it actually weighs more than I do.
- 7:58I use it as a door stop.
- 8:00No, it took her four years and she thought it was gonna take six months
- 8:04to update her original book What to Eat, and she found out that all the
- 8:10food that she had discussed in the original book doesn't exist anymore.
- 8:15You know, that's how fast everything churns through
- 8:17all these fads and whatever.
- 8:20So here's my take on it.
- 8:22and interestingly, she said the Same thing.
- 8:25So I feel somewhat affirmed.
- 8:28Okay, so here it goes.
- 8:31We look at ourselves as caved women.
- 8:35Let's just be a cave woman for a moment.
- 8:37All right.
- 8:38What time did you wake up?
- 8:39when some light hit the cave And then you heard the Tweety birds,
- 8:44And then you said, man, I'm hungry.
- 8:46And guess what?
- 8:46There was no seven 11.
- 8:48There's no Kroger grocery.
- 8:50Come on out.
- 8:51No
- 8:51Susan M. Kleiner, PhD:
- 8:51refrigerator.
- 8:53Pam Peeke, MD: Like, girl, your your ass is up and moving because if you
- 8:58don't move and groove, there is no food.
- 9:00Right?
- 9:01And so you get up and suddenly you are physically active.
- 9:05No gym needed, man.
- 9:07You gotta survive.
- 9:09And so you're up with the Tweety birds part of This is survival.
- 9:12You don't wanna be in there when bad things wanna crawl in there
- 9:15and, You know, have you for lunch.
- 9:17So out you go with your little, You know, tribe or.
- 9:21Whatever the hell.
- 9:22and, you know, you're, you're foraging and messing around and
- 9:27you know, you pick up what you can.
- 9:28Oh look, there's a, a raspberry bush.
- 9:31let's grab some of that stuff.
- 9:33Instead of saying like, oh, I can't have that.
- 9:35It's got carbs in it.
- 9:38I mean, I just wanna laugh my ass off.
- 9:40Every time I think about how ludicrous it is.
- 9:42It is, it is like, oh my God, it is.
- 9:44It's some carbs and yeah, it's called Living in Survival.
- 9:49And now eat the, eat the whole bush if you have to.
- 9:51Come on now.
- 9:53And then of course you know if you're lucky, lucky you get one main meal.
- 9:59That day.
- 10:00Otherwise what you have is a bunch of stuff you could just pick and poke and,
- 10:05hope that, you know, you can pretty much survive until the next day when
- 10:10hopefully hunting is more productive.
- 10:14And so you're running around physically active.
- 10:17Just by virtue of survival.
- 10:19and you're eating a little here, eating a little there with
- 10:23regard to physical activity.
- 10:24You're resting here, you're resting there, so it's this beautiful harmony
- 10:30of a little here or a little there all intersperse throughout the day, and
- 10:36there are definite times when you have nothing to eat when you're fasting.
- 10:42I mean, it could be that it's snowing out or, you know, whatever the issue may be.
- 10:46and our bodies were meant to utilize fasting, to our metabolic benefit.
- 10:54And we see this in all of the research that's poured out over this whole issue.
- 10:59So, I look at the cave woman.
- 11:03You know, kind of ethic.
- 11:04And I say, you know, women say, yeah, but today is 2026.
- 11:08And I'm like, I don't wanna break your heart.
- 11:11You know, really, I, I am the messenger, so don't hurt me here.
- 11:14But to affect enough metabolic change in your genome.
- 11:20To thoroughly adapt to the insanity of what we do to our
- 11:25bodies today is impossible.
- 11:28'cause it takes a long time for the genome to really show,
- 11:32You know, substantial change.
- 11:34The epigenome obviously does, but the genome itself.
- 11:39So, for all intent and purposes I see myself as that cave woman.
- 11:43Dammit.
- 11:43So I'm up with Tweety Birds and I know, I know there are night owls out there.
- 11:48We'll get to you.
- 11:49by the way, if you are a night owl, you are the one guarding the cave.
- 11:54You were the one to raise your hand saying, oh, I got this.
- 11:57You know, like I'm a night owl.
- 11:59but for the rest of them, You know, the mass majority like to,
- 12:02You know, do the morning thing and you just follow it like that.
- 12:07And what time do you think they stopped eating?
- 12:10When do you think they stopped
- 12:11eating?
- 12:13Yeah, it's like they either never had anything to eat in the first place.
- 12:17in which case, You know, they went directly into some level of
- 12:21a fasting state or they actually had something to eat, you know,
- 12:25that was fairly substantial.
- 12:27And then, you know, as soon as it became sunset, it's like,
- 12:31my ass is outta here because.
- 12:32All kinds of things crawl out of the forest in the dark
- 12:35and they want me for dinner.
- 12:37And so you go back to a safe place And what do you do there?
- 12:41Well, you like, You know, crank out your iPad and your iPhone and
- 12:44you start doing a little texting.
- 12:46Come on now.
- 12:47No, it was dark in there and plus you didn't wanna have a whole lot of anything
- 12:52going on 'cause you don't wanna attract.
- 12:53Any of the bad boys.
- 12:55And so you went to bed in an appropriate time.
- 12:57You went to sleep and up you went with the Tweety birds.
- 13:00Basically rinse and repeat.
- 13:03Okay.
- 13:04That's the way it was supposed to work.
- 13:06let's look at it now.
- 13:08Sue.
- 13:08What does it look like today?
- 13:10What's your classic kind of situation today?
- 13:14Flash forward.
- 13:15Susan M. Kleiner, PhD:
- 13:15Well.
- 13:16Six situation today is, you know, it's fascinating, when you've been in a field
- 13:23for a long enough time that you see the arc of change and sort of the histotripsy
- 13:30points when, things impact our behaviors.
- 13:36So in nutrition and particularly Marian Nessel, Has seen the impact of the
- 13:44food industry on our eating behaviors.
- 13:48So, It used to be that we ate three squares a day, let's just say that, and
- 13:54that's been going on a long time, right?
- 13:56We've eaten three square meals a day, breakfast, lunch, and dinner.
- 14:00And sometime during the 1980s that I remember, 'cause I was already a
- 14:06registered dietician in the field of sports nutrition, we started
- 14:11to talk about snacking And that athletes needed more fuel and they
- 14:18needed to prefu before exercise.
- 14:20And this was all.
- 14:21Focused in sports and very active people.
- 14:26Well, the snack food industry, which was taken over by the cigarette
- 14:31industry who were masters of altering habits and behavior and influenced
- 14:38the way people thought about things.
- 14:41They saw this as an incredible opportunity.
- 14:44Also, as they started to develop all of these.
- 14:47Ultraprocessed food technologies, and it was this opportunity to say, wow, if
- 14:55Americans start snacking, we can feed them and sell them a ton more food.
- 15:03And so all of a sudden, what was to me, sports nutrition advice
- 15:09became advice to the average person.
- 15:14In concert with, I have to be honest.
- 15:16I'm going to call 'em out.
- 15:19Gatorade.
- 15:19When I started working in the early eighties and mid eighties with
- 15:24Gatorade, Gatorade was a sports drink.
- 15:27You drank it to fuel your exercise at a point.
- 15:33Late eighties, early nineties, they changed their marketing to what
- 15:39they called a beverage of choice all day long, which is when I stopped
- 15:43working with them because I didn't understand why kids in school should
- 15:47be drinking Gatorade all day long.
- 15:49Why anybody should be drinking Gatorade all day long.
- 15:52And it was all happening at the same time.
- 15:55Everybody needs to eat small, frequent meals all day long.
- 16:00And then it became three big meals with three snacks a day, And we were
- 16:06just buying the heck out of all these products, and there was never any.
- 16:12Substantiation that that was better for us.
- 16:16At the same time were, we were being told that, you know, fats were bad
- 16:21for us because we had the Framingham study that started to tell us
- 16:25there was a problem with fat in our diets and leading to heart disease.
- 16:28And so now we had all these new processed foods that were high in carbs.
- 16:34Processed carbs, low in fats.
- 16:36You could eat those all day long.
- 16:38And here we are.
- 16:40We are eating all day long.
- 16:43All kind of things that may or may not give us good nutrition.
- 16:48and certainly way more calories than we need to be eating
- 16:55because we never need and process.
- 16:57Right.
- 16:57And so your story about how people ate at the beginning of human history.
- 17:07It is certainly relevant because, except for maybe a minor few flips of
- 17:14a genome, we are in the same bodies.
- 17:17Right.
- 17:18as you said, we have not changed in the last, what, 10,000 years.
- 17:23Pam Peeke, MD: Sue, I identify as.
- 17:24A
- 17:25Susan M. Kleiner, PhD:
- 17:25Yeah.
- 17:26There we go.
- 17:27Pam Peeke, MD: I do.
- 17:27I identify as a
- 17:29Susan M. Kleiner, PhD:
- 17:29but but you would be a miracle cave woman, right?
- 17:33Because.
- 17:34Women didn't live much past their childbearing years.
- 17:39And so the new story is because when you're young, you can do almost
- 17:46anything and survive until you get a cut and there's no penicillin
- 17:50and you die of an infection.
- 17:52But when you age.
- 17:56We also have some other things happening that may not have been
- 18:01happening during 10,000 years ago, but that we are understanding
- 18:06through research does help and.
- 18:10One of those things is not having our digestive systems so full
- 18:17all the time that the rest of the body doesn't get the blood flow.
- 18:22It needs to recover on a daily basis.
- 18:24Pam Peeke, MD: Nor does it have an opportunity to clean up its mess,
- 18:29which is where fasting comes in.
- 18:32And that fasting piece, you know, people just need to understand.
- 18:36What that's all about.
- 18:38And I honestly think the work of both, Satchin Panda at the
- 18:42Salk Institute, as well as Dr.
- 18:44Volter Longo, at uscs, their large, longevity and, geriatric, institute, has
- 18:53really helped us understand why it is.
- 18:56Extremely important and beneficial to allow the body time to, as it
- 19:03were, rest and digest, which is what the parasympathetic nervous
- 19:08system does, rest and digest.
- 19:11Instead, what we do is we eat.
- 19:1324 7, I swear it's insane.
- 19:18there's no time for the body to clean up, the breakdown products,
- 19:23of both physical activity as well as, you know, what we eat.
- 19:28and therefore the non feeding time, you know, we call it fasting, but the non
- 19:33feeding time is exquisitely important.
- 19:38there was a fantastic Japanese, scientist who won the Nobel
- 19:42Prize, in identifying autophagy.
- 19:45Um, And that.
- 19:46Fancy word basically means how shall I say this?
- 19:50you're gonna love my analogy.
- 19:52So it's like a Dyson goes right through all your cells and sucks
- 19:58up all of the debris, the dying cells, the pieces of cells hanging
- 20:04out, toxins and whatever else.
- 20:07During the phase of autophagy, when you've, you've had at least six hours for
- 20:15sure, of not eating, And then you enter, a stage of autophagy, then it's important.
- 20:25To honor that time where your little dyson's running around, cleaning up
- 20:29the mess, And then you have cellular rejuvenation and regrowth, And the
- 20:37cells aren't having to deal with all of this extra debris and whatever.
- 20:42That was the magic behind, You know, the whole issue of the
- 20:46fasting or non feeding hours.
- 20:49Now the question is, what does that actually look like?
- 20:52You know, if you pull up all kinds of articles about intermittent
- 20:57fasting or whatever, you know, you'll see everything from people who
- 21:02will once a week just drink water.
- 21:06for once a week.
- 21:07Other people are like, okay, well, what I'll do is I'll cut my calories
- 21:13like in half, every other day.
- 21:16And I'll do that.
- 21:17So I'll, I'll kind of, as it were, suffer every other day.
- 21:21And that's alternate day, fasting.
- 21:24And then you have all kinds of nuances with regard to how many hours per
- 21:31day you actually fast versus eat.
- 21:35So, between you and me.
- 21:38In talking to some of the world's experts, who I met at Vaulter's, you know, big
- 21:44fasting conference a number of years ago.
- 21:47they came in from everywhere, Europe, Australia, uk, all the rest of it,
- 21:53and they all said the same thing.
- 21:54The sweet spot was eating during a window of 10 hours.
- 22:00And having 14 hours to be able to, get that little, vacuum going
- 22:07in your body and cleaning things up.
- 22:10That's what that's all about.
- 22:12and it really isn't a vacuum, per se.
- 22:14What I'm being facetious, autophagy actually means.
- 22:17You are eating yourself, meaning that your cells, the old debris is being
- 22:23cleaned out, by systems, throughout your body, that are refreshing your cells.
- 22:30So I think I'm arguing now for the ability to be able to find a way.
- 22:39That everyone out there in the Herb podcast land can, individualize
- 22:44and customize and experiment with, being a little bit more,
- 22:50how shall we say, cave woman ish.
- 22:53in which case you have to find out based upon your crazy life and all the things
- 23:00that get in the way and back and forth.
- 23:03What works best for you?
- 23:05When I was talking to Dr.
- 23:06Nessel, she said, you know what, everybody says A way to eat is
- 23:13successful if you can sustain it over time and it has healthful benefits.
- 23:22if you can't check those two boxes, whatever you're doing is crazy.
- 23:27Susan M. Kleiner, PhD:
- 23:27Yeah.
- 23:27So, yeah, absolutely.
- 23:29I mean, it's always, you know, speaking as a nutrition coach, if
- 23:34you can't do it, it doesn't matter.
- 23:36I could create the best, healthiest diet in the world.
- 23:40If people don't eat it, it's irrelevant.
- 23:43And so, ideally, we can.
- 23:47Hang our hat on a few data points, but it doesn't mean that if you can't,
- 23:52if this doesn't work for you, then.
- 23:55Drop the whole thing.
- 23:56So as you said, eating in the morning versus if you set your 10 hours, let's say
- 24:03starting at six or seven in the morning or eight in the morning, whatever time
- 24:10in the morning, you have something that resembles a breakfast in your mind, eating
- 24:16earlier, And then going into your fasting.
- 24:21Sort of by seven or eight o'clock at night.
- 24:26not eating late at night, rather than saying, I'm gonna eat for 10 hours
- 24:30and I'm gonna start at noon and I will eat till 10 o'clock at night.
- 24:34Well, the data are showing us that it's actually more healthful.
- 24:40And if you're trying to lose fat, It is slightly.
- 24:45Better to eat in the morning versus eating late at night.
- 24:51So that's
- 24:53Pam Peeke, MD: Well, there's another reason for that.
- 24:54Piling on that we know that, um, throughout our body
- 24:59have a circadian rhythm.
- 25:01One of them, is insulin.
- 25:04And so insulin tends to be most efficient in the morning up
- 25:09until about early afternoon-ish.
- 25:12So if you're eating a boatload of food, you know, like say Mount St.
- 25:16Pasta for dinner, Then you are flooding your body with a boatload of carbohydrate
- 25:23that your insulin can't manage optimally, And that will be stored as fat guaranteed.
- 25:29So the rule is if you really wanna have some great carbohydrate, that usually
- 25:35involves like a starch, then to do it in the morning, or at, I love to call.
- 25:41The meal, that takes place around one-ish, you know, two-ish.
- 25:45the main meal of the day, that's the main meal.
- 25:48'cause all of your hormonal systems are operating optimally and you'll be able to
- 25:56metabolize much better than if you were, you know, chowing down at nine o'clock
- 26:02at night or eight o'clock at night even.
- 26:05So you gotta be so careful.
- 26:06That's why I keep saying that clock.
- 26:09Circadian rhythm.
- 26:11You know, we, we could talk all day long about fancy programs you and I can
- 26:16create and they can sound real sexy And we could TikTok them out and whatever.
- 26:21But I don't want, again, I don't wanna break anyone's heart out there.
- 26:24Here we go.
- 26:25Okay.
- 26:26You have a prehistoric circadian rhythm built into every cell of your body.
- 26:33Every cell has its own clock, and you know you can wish and hope all you
- 26:39want, you could pray over your body.
- 26:42It ain't gonna change you.
- 26:44You're gonna have a circadian rhythm that honors the rotation of the earth.
- 26:51Right, because that's happening on a circadian rhythm.
- 26:54Last time I looked it was called sunrise and sunset.
- 26:57And you can't mess with that.
- 26:59I know.
- 27:00You're trying to mess with that.
- 27:01You go put, I got lights on at nighttime.
- 27:04Yeah.
- 27:04Well thanks for sharing, but you know, your body is still working
- 27:08on a Arcadian rhythm, you know, and you gotta, stay with it.
- 27:13And that's why I argue, against anything strange.
- 27:19That really deviates from that too much.
- 27:22You know what I mean?
- 27:23You could still customize.
- 27:24Susan M. Kleiner, PhD:
- 27:24And that 10 hour window, I like that, um, even better than the
- 27:30eight hour window and 16 hour fast.
- 27:33Is because as women typically we can't get in all the nutrition that we
- 27:41really need in a brief period of time.
- 27:45I mean, some people do four hour eating windows.
- 27:50It's just not long enough for us to eat well and get in all our nutrition.
- 27:56And so the eight hour window.
- 27:59eight to 10 hours, let's say, is much more practical for most of us and
- 28:06allows you to live a social life, allows you to go out to dinner with people.
- 28:12Just say, I need an early bird dinner, but,
- 28:15but.
- 28:16Pam Peeke, MD: Oh no, not the blue plate special.
- 28:18Hey, listen, when we come back, Sue, I'm gonna be talking more about this whole
- 28:24issue of how do we make this practical.
- 28:28You and I as fellow cave women, I.
- 29:31And we're back.
- 29:32Okay.
- 29:33Hey, cave woman.
- 29:35So here's the gig, We wanna make this work so that women, you just said it,
- 29:41women can see the practicality here And the fact that it will help you.
- 29:47Because when women say, well, I'll go to the gym and I'll
- 29:49just work it all off, look.
- 29:51Don't wanna break your heart.
- 29:52That's not the way this goes.
- 29:54The science shows that if you really wanna peel off some extra fat, the
- 29:59best way to do it is through nutrition.
- 30:01And then physical activity adds the period at the end of the sentence,
- 30:07So, It makes it sustainable, and it maintains that beautiful metabolism.
- 30:13But nutrition is absolutely queen here, isn't it?
- 30:17Susan M. Kleiner, PhD:
- 30:17Yes, yes.
- 30:18Although if you are focusing only on nutrition for weight loss and
- 30:23restricting your calories, you're also losing more muscle than if you
- 30:28would be working out in the gym.
- 30:30You'll hang on to more muscle, while you lose weight because we
- 30:34really don't care what you weigh.
- 30:36I mean, what you weigh only represents the relationship of your body to gravity.
- 30:42What we care about is the proportion of fat to muscle.
- 30:46And so, we're always gonna lose muscle when we're losing weight.
- 30:51we hope to lose more fat and less muscle.
- 30:53When we're gaining weight.
- 30:54We're gaining, hopefully, if we're working out, we're gaining more muscle
- 30:59and less fat, but it's always a ratio.
- 31:01And so in this case, we want to focus on our diet, on our nutrition,
- 31:08on the food that gives us.
- 31:11All of the nutrition to build our bodies up so we don't tear them down.
- 31:16The point is, as we live through each day, each week, each month,
- 31:22each year, that we get stronger, that we are more capable, not less.
- 31:28And so that requires.
- 31:30Really good solid nutrition.
- 31:32And so over that, let's say 10 hours or eight hours, you still need
- 31:37all that protein that we've talked about and it's been talked about
- 31:41multiple times on this podcast.
- 31:43and you don't wanna get in, you know, 90 grams of protein in one slug.
- 31:48That's disgusting.
- 31:49It's also not good for your intestines and your
- 31:53digestive.
- 31:54Right.
- 31:55And so when we, we want to separate, we still wanna separate out our food,
- 32:01we still wanna fuel our exercise.
- 32:04We don't want to under fuel training.
- 32:07You can under fuel later in the day, but not before your exercise.
- 32:11'cause then you don't get the biggest bang for your buck when you go in.
- 32:14To train, And so making sure you're well fueled, getting in your protein,
- 32:19getting in all the fiber that we need so that you still have that, low
- 32:25inflammatory response in your gut, which transfers out to the whole body.
- 32:31To get in the bone building minerals.
- 32:33I mean, I could go on and on.
- 32:35So the story is the same whether you are on a calorie restricted diet or
- 32:41a time restricted eating pattern, you still need the basic foundational
- 32:47nutrition to be super healthy and to train well, and to keep your mind clear
- 32:53and do all the things that you wanna do.
- 32:56Pam Peeke, MD: Actually magic about, your natural circadian rhythm is.
- 33:06effortlessly, I mean, effortlessly, you end up eating fewer calories because
- 33:12you have less time to munch out.
- 33:15I mean, if you're eating well, actually, when Satchin Panda began his, his
- 33:19scientific work, he went ahead and he just found out what a baseline number of hours
- 33:25of eating, of the average American, and he found out that people eat on average.
- 33:3215 to 16 hours a day.
- 33:35I mean, it's like a second career.
- 33:36Excuse me.
- 33:37Hi.
- 33:38I'm a software engineer and I'm also someone who eats, um, you
- 33:42know, it's like your second career.
- 33:44So, you know, when he saw that, he was like, uh, Roro that,
- 33:48that's leaving No time for that.
- 33:51cellular clean.
- 33:52The autophagy, people are eating later, they tend to move it down and
- 33:58they tend to, you know, pack in the largest chunk of calories, usually
- 34:04processed in very heavy stuff by volume.
- 34:08in the evening, which is again, the worst time to do all that.
- 34:11That's like a guaranteed, a way to be able to pack on pounds.
- 34:16Susan M. Kleiner, PhD:
- 34:16You know, on your way to marginal diabetes.
- 34:19Pam Peeke, MD: I, I know it's like pretty nuts.
- 34:21So This is where he just said, okay, let's all calm down here.
- 34:25Now, you know, all together now, and This is the way it's gonna look.
- 34:30What we're gonna do is we're going to come up with a reasonable window.
- 34:35Now, by the way, the only reason why he used in his experiments, which he
- 34:40did, in the beginning with, animals.
- 34:43these are rats and, mice.
- 34:45And then he eventually went to humans.
- 34:47He used 16 eight because it was the easiest thing.
- 34:51And also, as you know, and I know as researchers, whenever you
- 34:55do research, you, you wanna get your biggest bang for your buck.
- 34:58You go for a bit of a harder protocol where, you know, for a natural fact
- 35:04you're gonna get a really cool result.
- 35:07You know what I'm saying?
- 35:08And so, I think that.
- 35:10Susan M. Kleiner, PhD:
- 35:10Kind of the deck.
- 35:11Pam Peeke, MD: well, the other reason why you're gonna love this,
- 35:14when Sachin told me I fell off my chair, I was laughing so hard.
- 35:17He said in my original experiments, which were all published in Cell,
- 35:22which is one of the top, mags, journals out there for us.
- 35:27Um.
- 35:27his head research, guy running, you know, managing the protocol and everything.
- 35:33For him, he needed to be home by a certain time.
- 35:37Okay.
- 35:37I'm not kidding.
- 35:38I, I wish I could make this up.
- 35:41No.
- 35:41And he said, You know, I can do the 16 eight thing 'cause it works well
- 35:46with, You know, my household and how everything's wor, but I can't do
- 35:49this other, you know, And we can't do, You know, 14, 10 and whatever.
- 35:54He says, I gotta get these rats eating over eight hours And then You know,
- 35:58we're dead And then let's move along.
- 36:00So I laughed.
- 36:02and that's just another perfect example of how crazy science can be when
- 36:07you're executing these experiments.
- 36:10So.
- 36:10I personally, ever since I met Satchin, I'm not kidding you,
- 36:14I literally changed on a dime.
- 36:17I went out to the Salk Institute.
- 36:18I was out in the West coast for other meetings and I just, popped on by
- 36:23to see Satchin And we spent hours.
- 36:26the science was so compelling that I switched over everything for myself.
- 36:31I have never felt better in my life.
- 36:34So, you know, plenty of wiggle room.
- 36:37Now here's where, where it gets cool, do you think you have to live
- 36:40like this every single freaking day?
- 36:42Of course not.
- 36:44there's wiggle room.
- 36:45So some days I may do 12, 12.
- 36:49Which is what a lot of people do.
- 36:50You know, 7:00 AM to 7:00 PM we're all good.
- 36:53Whatever.
- 36:54Okay.
- 36:55Sometimes I'll do, 10 and 14 some days just turn out to be wild and
- 37:01crazy and I end up with a 16 eight just 'cause life happens that way Now.
- 37:07He did more experiments you know, very, very well.
- 37:11And what he did was over the weekend he decided to just sort of mimic what
- 37:16Americans do, which is let it rip.
- 37:19Okay?
- 37:20So he, he allowed the.
- 37:23mice or rats to eat whatever in the hell they want.
- 37:27Now, they were no longer restricted to the 16 eight and whatever, and
- 37:31they ate whatever they wanted.
- 37:33I mean, they had food available 24 7 and sure to form, you know, they
- 37:39definitely took 'em up on that.
- 37:41But here's what's weird.
- 37:42When they looked at the metabolism, all of the metrics, everything from blood glucose
- 37:48to insulin levels and all the rest of it.
- 37:51When they actually looked at their metrics, the animals who
- 37:56had been Monday through Friday, pretty much on the money, right?
- 38:00And then let it rip on the weekend.
- 38:03It didn't even matter with their weight, body composition
- 38:10or with any of their, labs.
- 38:13And he was astounded, astounded.
- 38:16then he began to put two and two together.
- 38:19And here's something that you're gonna love when you do this little
- 38:24honoring the the clock thing.
- 38:28What happens is guess which Fat Depot is the most sensitive to weight loss?
- 38:33Visceral fat.
- 38:35That's the Mac daddy.
- 38:36That's the one you need to really control because when you have too
- 38:40much intraabdominal fat, too much of it, obviously you have some, it's
- 38:45normal, but too much of it, man.
- 38:47You got diabetes, like you said, cardiovascular disease.
- 38:52Cancer's up, You know, it's a bad situation.
- 38:55So I love the fact that your body forgives you for your
- 39:00little, nuances on the weekend.
- 39:03so long as you're right back at it on Monday.
- 39:05And most people have found after they've been at this for a while.
- 39:10They tend not to deviate too much anymore.
- 39:13It's sort of, have you noticed that in, in, in working with people?
- 39:17Susan M. Kleiner, PhD:
- 39:17Yeah, so this concept of the 80 20 rule has been around forever, right?
- 39:23Pam Peeke, MD: Oh no, not the 80 20 rule.
- 39:26Oh, no.
- 39:27Susan M. Kleiner, PhD:
- 39:27that's kind of what you're talking about, that 80% of the time you're on task
- 39:33and 20% you get to, you know, deviate.
- 39:37And so, the body.
- 39:40Likes to, I don't wanna say go in a straight line, but it likes to stay
- 39:46within certain parameters And so you train it, and when you train it.
- 39:55Even within whatever intermittent fasting or time-restricted eating, whatever, even
- 40:02calorie restriction, when you set it on a path, it likes to stay on that path.
- 40:10Even if you do a little deviation, you drive, you know, off the road.
- 40:17If you completely go in the ditch it, you know,
- 40:21all
- 40:21Pam Peeke, MD: we've been there.
- 40:22Trust me.
- 40:24Susan M. Kleiner, PhD:
- 40:24You go on a vendor and it's, it's over.
- 40:27But if you kind of, it's teleological or we're giving, description to body
- 40:34cells as if they have a brain, which we actually know, they kind of do.
- 40:39It's amazing a whole nother research area.
- 40:42But When we, let the body understand what the expectation
- 40:48should be, it stays on track And so that we can deviate like this.
- 40:54That's why all these different patterns, two days of fasting, five days of
- 41:01eating, or three days of alternate.
- 41:05Sort of, kind of sort of fasting and four days of eating more on
- 41:10time restriction or whatever.
- 41:13You do those things.
- 41:16the body will adapt.
- 41:18I think in my experience of working with many, many, many people, the
- 41:24sort of regularity of every day works best And the two and five often.
- 41:33You know, people start out that way and they fall off the wagon.
- 41:37It becomes difficult, first of all, to truly fast all
- 41:40day and still be functional.
- 41:42I mean, unless you're someone who has no other responsibilities.
- 41:47To show up for anything.
- 41:49Fasting all day is uncomfortable and you don't, perform at your best, And so
- 41:56that's why this time restricted eating.
- 42:00is so beneficial.
- 42:01It puts us in the sweet spot during the hours that we need to be sharp and
- 42:07alert And we can feel well fueled to go to exercise, And then it lets us.
- 42:14You know, rest our body and recover in the alternate hours.
- 42:18And that's why I really, I like that pattern.
- 42:22But as you are saying, everyone should find what works for them and
- 42:27know that This is not mandatory.
- 42:30You can also, if just eating less without time restriction
- 42:36works well for you, then do that.
- 42:40Pam Peeke, MD: I mean, you know, it, it, you have to experiment And also you.
- 42:45Know, let's talk about women, you know, women's needs their nutritional needs.
- 42:50They'll change over time.
- 42:53so I've gotta tell you the little anecdote with, Dr.
- 42:56Nessel.
- 42:57it was a really great, interview 'cause she's always been one of
- 43:01my, kind of icons in nutrition and she turned out to be a riot.
- 43:05She's 89 years
- 43:06old.
- 43:08Susan M. Kleiner, PhD:
- 43:08you
- 43:08know, writing books and emer
- 43:11Pam Peeke, MD: Yeah.
- 43:11And she, well, she's got her faculty office and You know, and
- 43:15you're like, I wanna be like her.
- 43:17toward the end of the interview, we were just hanging out and I said, so
- 43:21like, how do you eat during the day?
- 43:23Like, You know, you're one of the queens of nutrition, people buy all your books
- 43:27and you know, we hail you as the one.
- 43:30She goes, oh, okay.
- 43:31Well let's see now.
- 43:33Yeah, I wake up in the morning and I don't like breakfast,
- 43:37so I'm like, okay, alright.
- 43:40You don't like breakfast?
- 43:41She goes, yeah.
- 43:42I don't really start feeling like I wanna have anything until about 11, and
- 43:46I'm thinking about all the RDS out there falling off their chairs, going, what?
- 43:51but, hey, I don't wanna, you know, again, Break your heart in 5,000
- 43:57pieces, but she's 89 and you are not.
- 44:01And that means that she knows something that You know, and
- 44:04she's awfully healthy right now.
- 44:07And so why don't you listen on up.
- 44:09So what's the lesson here?
- 44:11And her telling me that, well, you know, let me finish the rest of the day.
- 44:15So I said, oh, so what do you have?
- 44:16She goes, you know, probably some cereal.
- 44:21I said, really?
- 44:21What kind?
- 44:22And she goes, oh, multi-grain.
- 44:24I like that.
- 44:24And might do some multi-grain stuff and every, everyone's falling off
- 44:28their chairs, gluten and all those horrible things that are ripping
- 44:32your microbiome into shreds.
- 44:35And meanwhile she's like, eh, it's worked for years, you know?
- 44:38And then I said, well, what do you have the rest of the day?
- 44:41I dunno.
- 44:42You know, it's like whatever's around and, you know, I just sort of put it together.
- 44:47And then, I said, well, when do you finish eating?
- 44:50And she says, You know, I eat early.
- 44:53notice I said that, and I eat early, you know, like I'm, I'm finished up.
- 44:58I no later than, you know, 6, 6 30 and I'm good to go.
- 45:03Right?
- 45:04so.
- 45:05What did we learn from all of this?
- 45:08We learned that, there's a lot more wiggle room than you think, number one.
- 45:15Number two, being super rigid and strict and, you know, having
- 45:23to grind your teeth through it.
- 45:25Is not helping you.
- 45:28last time I looked, I don't know, food's supposed to be delicious and n
- 45:32nourishing and nutritious and enjoyable, You know, all those neat things.
- 45:38So what happened to that?
- 45:40And, I think that also what's all over TikTok and, you know,
- 45:46Instagram and God knows what else.
- 45:48YouTube are a bunch of young men especially who are on very rigid
- 45:55kind of stuff that, you know, they give it all kinds of and whatever.
- 46:00And then they've got, you know, kind of tech bro bodies, they're
- 46:04lifting weights, doing their thing.
- 46:05Susan M. Kleiner, PhD:
- 46:05They're shooting into themselves
- 46:07Pam Peeke, MD: Yeah, well, I'm not gonna even go there.
- 46:10Um, And so, I think it really influences a lot of people.
- 46:15Now let's quickly pivot to something that you and I were
- 46:18talking about before the show.
- 46:21What is going on with women?
- 46:24Now we're talking about health, And we know that if you live a little bit
- 46:28more like a cave woman, you know, with nuances around that, your numbers,
- 46:33your lab numbers improve beautifully.
- 46:36Your visceral fat and your belly fat improves, tremendously.
- 46:41We have tons of evidence that shows that your waist.
- 46:44Circumference decreases, and of course if you're having enough protein and
- 46:48lifting weights, your muscle mass will be optimized as well, but.
- 46:55Oh my God.
- 46:56So, you flip through the pages of Vogue Magazine and we're
- 47:01back to the skinny women again.
- 47:04you know, I saw one the other day that had about 14 feet between her thighs.
- 47:08she has like, what, where did you come from?
- 47:11stick land.
- 47:12yet for a while there things had changed.
- 47:15What happened there, Sue?
- 47:17Susan M. Kleiner, PhD:
- 47:17I think it's the fashion industry, honestly.
- 47:19I mean, they need us to buy new stuff.
- 47:23Year in and year out.
- 47:25And if they change the body type, then the fashion itself changes.
- 47:30And so between Hollywood and the fashion industry, and of course social media.
- 47:38We are seeing a return to the bad old days of the 1980s.
- 47:44Before that, I remember Twiggy, which was the same kind of image,
- 47:50but we didn't quite understand.
- 47:51I think what we were looking at at that time.
- 47:54That was the 1960s.
- 47:56And so, by the 1980s, sort of the anorexic body type became
- 48:03very popular And the whole.
- 48:06Concept of, a muscular woman or a well-defined body for a
- 48:12woman just was not in vogue.
- 48:16It was neither in vogue, nor was it in Vogue.
- 48:19And so we went through such hard work to change that image, to educate
- 48:27a whole new generation of women to be comfortable in their skin.
- 48:32That who you are does not is not defined by the way your body looks That.
- 48:39Health is what matters.
- 48:41Taking care of your nutrition, your mental health, your physical
- 48:45wellbeing, all of these things are good for, as we talked about, health
- 48:50span longevity and to be strong contributors to the world around us.
- 48:56And now it is going back.
- 48:59It is, we are seeing, skyrocketing levels of cigarette smoking
- 49:04in the younger generation,
- 49:06Pam Peeke, MD: And for a long time they had given that up too.
- 49:10Well, there's another layer to all this And the other layer, it's very interesting
- 49:15once these, weight loss, drugs.
- 49:18Popped up.
- 49:19Now all of a sudden, there was the most fascinating op-ed in the
- 49:23Wall Street Journal written by a psychiatrist whose name is Alfred May.
- 49:28He might be a psychologist, psychiatrist, one of, I think he's a psychiatrist.
- 49:32What he basically said was patient's were coming in saying that they had
- 49:40bought into the body positivity thing.
- 49:43when they say they bought into it, they did that.
- 49:46Publicly, but secretly to themselves, they never bought it.
- 49:50They were never happy with their bodies.
- 49:53And now that they're on GLP and their bodies are changing in a way That is more
- 49:59beneficial in terms of their health and wellbeing, their numbers, the labs And
- 50:04the rest of it, they're almost afraid to say anything because there's been this.
- 50:10Kind of an ethos out there of it is okay if you're, substantially obese.
- 50:16And when according to Dr.
- 50:19Alfred, he said that, no, that's not true.
- 50:22That's not really true at all.
- 50:24That most people really wanted to change for the better.
- 50:27They just had no tools to do it.
- 50:29And now you have these meds and suddenly the body positivity
- 50:34movement, per se, has morphed.
- 50:37Now I'm gonna make very clear to everyone what I mean by this.
- 50:43Every woman comes in a magnificently awesome shape and size.
- 50:49You need to love yourself.
- 50:52you need to be able to be proud of who you are, mentally, physically, spiritually.
- 50:58You need that.
- 51:00That is absolutely foundational.
- 51:03But you also have to pay attention to your health.
- 51:08And so health is exquisitely foundational.
- 51:11You believe whatever you want, but if you have no health.
- 51:14Then you got a problem.
- 51:16And now you know, if you look at all the new NASH global trends, the global trends
- 51:23are health, wellness, and longevity.
- 51:26So.
- 51:27If you're doing everything you can to be as healthy as you can.
- 51:32How about that meditation?
- 51:33How about taking, you know, those walks?
- 51:36How about connecting with other people?
- 51:38How about eating nutritious whole foods and doing something
- 51:41radical called cooking?
- 51:43how about, addressing your sleep and your stress, all those things.
- 51:48That's what I'm talking about.
- 51:49And then your body will follow.
- 51:53Don't start with the body.
- 51:55The body is going to follow when the process of how you live changes
- 52:02for the better and all along.
- 52:05You still love yourself, you're proud of yourself.
- 52:10It's just that you've got to remember to weave in health and wellness throughout.
- 52:19Susan M. Kleiner, PhD:
- 52:19Oh, absolutely.
- 52:20So the GLP one drug.
- 52:23Are an amazing advancement.
- 52:25Undeniably people struggling to find health who couldn't do it on their
- 52:32own, just eat less and exercise more.
- 52:35Right?
- 52:36Just like we say, just say no to drugs.
- 52:39Those things, platitudes are not helpful.
- 52:42And so the GLP one drugs I think are in an early phase, but they are.
- 52:50Helpful for the proper individuals.
- 52:53But even within that, as you're saying, even when you have the medical support
- 53:00or the pharmaceutical support, you still need to understand how to adjust
- 53:06your lifestyle so that whether or not you stay on those drugs forever.
- 53:12You are supporting health, And so I talk about weight loss is not a goal.
- 53:20Weight loss is an outcome of changing all the things that
- 53:25you have talked about and giving yourself a pat on the back each day.
- 53:29For going out for a walk, that's your goal.
- 53:33Being a little more physical, active, getting up off the couch, doing
- 53:37something and planning and carrying that through on a daily basis.
- 53:41Setting up a time when you have a creative, expression during
- 53:46your day, having your spiritual, opportunities, making sure that you
- 53:51have strong relationships in your life.
- 53:54Doing.
- 53:56You know, making the world a better place through volunteer work or whatever that
- 54:01may be, and eating well and hydrating well, each one of those on a daily basis
- 54:08or a weekly basis, Those are goals that
- 54:12Pam Peeke, MD: And that's exactly how we're going to end this,
- 54:15this fantastic episode with you.
- 54:18What a beautiful way to be able to summarize all that.
- 54:22Remembering, that both of us said the same thing and you said it so
- 54:26gloriously, and That is any level of excess fat in your body That is reduced.
- 54:33It was never the goal, it's an outcome because the real goal was to clean
- 54:39up all of those other elements to start with, And so I think that That
- 54:44is a powerful message coming from Dr.
- 54:47Susan Kleiner learned more about her incredible work at her website, Dr.
- 54:53Kleiner, and That is DRS.
