As someone who has experienced so many different sides of this, you have zero clue the degree to which your appetite and ability to suppress it is hormonal until you get hormonally compromised (and then fix it, in my case, happily)

Blaming individuals for a public health crisis affecting 40% of the population is absolutely silly. There are a lot of individuals like me, who overeat behaviorally, but that doesn't explain the scale of the issue. maybe 8-10% of the population has some sort of eating disorder, the other 30% are just regular people eating an american diet.
