That is contrary to what actual doctors who have spent their lives studying the issue are saying. I read just the other day that there are at least 14 different genetic markers that contribute to obesity. While I don't know exactly how many different medical conditions contribute to obesity here are just a few of them: hypothyroidism, Cushing's syndrome, Polycystic Ovarian Syndrome (PCOS), Prader-Willi syndrome, and certain hypothalamic issues. Medications used to treat other conditions, such as certain antidepressants, steroids, antipsychotics, and hormonal birth control, can also lead to weight gain and obesity. I find it strange that you mention "medications" that can "fix our bodies" in the same sentence as you saying we won't need GLP-1 drugs for life .. so which is it? Do we need medicine or not?
