Your brain remembers your old weight and fights to get it back

The human brain evolved to defend fat stores during scarcity and can treat a prior higher weight as the new normal, increasing hunger, cravings and reducing energy expenditure after weight loss. This biological "memory" explains why so many people regain weight after dieting — it's not a failure of willpower. Drugs like Wegovy and Mounjaro help by suppressing appetite signals, though their effects may diminish once treatment stops.
