GLP-1 drugs do not repair leptin resistance; they go around that sluggish circuit and act directly on the appetite-regulating neurons in the brain. That helps explain why they still work for people who have already done the lifestyle work, and why weight often comes back after stopping.
Genetics of Weight / Not Just Willpower
The idea that being heavy means a slow metabolism gets it backward: more body tissue takes more energy to maintain, and at the same height a heavier person usually has a higher resting metabolism. The genuinely slow stretch comes after weight loss; it is a consequence of losing weight, not the cause of gaining it.

Leptin · adipose-to-brain energy signal

EVIDENCERCT 1

READ THE ORIGINAL

The more fat you carry, the less you ought to want to eat. The signal that says enough on the body's behalf is leptin, which fat cells release into the blood: the bigger the stores, the more they release. The hypothalamus, the appetite region at the base of the brain, picks it up, switches on the neurons that make you not want to eat, and holds down the ones that make you hungry.

It is not the brief fullness after a meal. It is a long-term fuel gauge for your reserves. When reserves are ample, the brain relaxes and lets metabolism and reproduction run normally. When they are low, it sounds a famine alarm: appetite grows and resting metabolism is turned down. Yet high leptin does not actively push you to eat less.

This one-sided setup, tight at one end and loose at the other, is one of the main reasons weight tends to come back after a diet. It also explains why extra leptin never became a weight-loss drug for ordinary obesity: what those people lack is not leptin.
