Yes, there absolutely is a sense of "it was hard for me, but I did it anyway, you should do the hard thing too". But that's not out of nowhere. Willpower is a muscle. If someone never exercises it, it's going to atrophy. It doesn't need to be shameful, but people who promote these things need to seriously consider the reality that most people's hunger is caused by something real, and just not being hungry does not solve any of those underlying problems.
My mother is a little bit overweight, which is a problem of calories OUT being too low. She doesn't exercise enough. She doesn't have energy to exercise. That's a problem of calories IN being too low. She's taking a GLP-1 now to lose weight. It very exactly does not solve either of those issues. She has less energy. Most of the weight being lost is muscle mass. I think it's despicable that these things were rushed through the medical system. I don't think it's the layman's fault for being manipulated into thinking it's medicine.
