This. 100%. I was blessed with good genes from my parents. It is so easy for me to maintain a reasonable weight. (Same for them.) Until very recently, I hardly did any exercise for more than 15 years, except the occasional weekend hike (nothing too crazy). Yes, there is some degree of self-control around eating, but lucky people with good genes love to wag their finger as people who struggle to maintain their weight. Whenever diet/weight issues come up on HN, there are always some very interesting posts by people with food control issues. They know their brain is broken (too hungry too frequently, etc.), but they cannot do very much about it. I'm happy to see that millions of people are finally able to lose weight and keep it off using GLP-1 drugs.
