How have fat people gotten thinner without those meds up until now, then? Was their addiction not as strong as yours, as you seem to imply? They just didn't "understand"? Look, I went from being an absolute fucking fatass to 8% body fat out of willpower alone when I was 17. It took a lot, namely destroying every bad habit I upheld for years regarding food and exercise, but I wanted to do it bad enough, so I did. It was a really extreme and sudden change of mindset, like a flip of a switch, actually, because I had enough of the bullying and lack of self confidence. One day I just got mad enough and changed my whole life.

Mostly, they haven't. You and I are outliers.
The population-level data tells us that overweight people are mostly unable to control their weight in the face of modern food. That being the case, it doesn't seem unreasonable to look for alternative solutions to the failed option of just telling people to eat less.
edit: regarding strength of addiction - I mean, of course, isn't it profoundly obvious that different people will have different strengths of addiction? I can drink without the slightest inclination to excess, while others are broken alcoholics. My grandfather didn't have the slightest interest in food beyond the calories needed to survive, while I have to fight every day to eat well.
