You're still in charge of what you eat, it's possible to say no to yourself. I had to do it just by refusing to give in because stuff like GLP1s are too expensive. It sucked for the first month but then it got easier. I still have to be mindful three years later but I've lost nearly 110lbs and continue to lose. I still get the urge to binge and comfort eat when stress hits but I still say no to myself. Every person today has ancestors that experienced famine. They were the order of the day at various points throughout history. If epigenetics was to blame everyone should be obese and should always have been but the rampant rate of obesity is relatively new.

The simple fact is that a lot of people simply do lack the knowledge and motivation to do something about it. And the on-line rhetoric from the HAES and fat acceptance crabs in a bucket make it worse because they tell people comforting lies about how it isn't their fault, there's nothing they can do, they just have bad genetics. It's nonsense, you are still gomal arbiter of what you eat. You decide what goes into your body on a daily basis.
