New research reveals that your immune system may retain a lasting “memory” of obesity—even after you’ve lost weight—thanks to molecular markers lingering on helper T cells for up to a decade. This hidden legacy could explain why risks for diabetes, cancer, and immune aging persist despite healthy weights. Scientists studied humans, genetically obese individuals, and mice to uncover how obesity disrupts autophagy and immune senescence at the cellular level. Now, researchers are testing drugs like SGLT2 inhibitors to help erase this memory and restore immune function, emphasizing that true…
