First off, even assuming that your thesis is correct, are overweight people expected to just wait until we can fix our entire food system? Secondly, while I think it is unquestionably true that the composition of our diet has a significant effect on the propensity for obesity, it does remain a propensity. There are innumerable people that maintain a healthy weight, some with dedication and willpower, others with an almost effortless ease, and everything in between. And, we know from very basic science that reducing the inputs and increasing the burn will absolutely cause weight loss. Homeostasis is not necessarily easy to achieve, but it is certainly possible. But practically there's some combination of diet, genetics, psychology, metabolism, gut biome, viral agents, endocrine system and a million other unknown and unmeasured phenomena that feed into it. At least in the USA, there is an overwhelming feeling that if you have the capability to fix things yourself (change your diet, change your lifestyle), then pursuing an alternative that takes it out of your hands (bariatric surgery or non-surgical interventions or weight-loss drugs like semaglutide or liraglutide) is admitting failure. I propose that it is less productive to dwell on failure than it is to actually lose the weight. We should remain skeptical of a "free lunch" -- extraordinary claims require extraordinary proof -- but it does appear that we are getting closer to having workable solutions to curing obesity.
