Your stomach and throat can stretch quite a bit over time. And overeating regularly affects the production of the hormone which tells you you’re full, especially when you’re eating processed bullshit that’s scientifically curated to make you want more food. The mechanisms our bodies have for regulation of caloric intake were really not balanced for the modern American diet. American kids who are genetically predisposed to obesity need to try way harder to avoid it than the average human. We stuff so much goddamn sugar in literally everything. Why is our regular bread so sweet? And once obesity sets in, the feedback mechanisms get really difficult to counteract. Shit sucks.

Edit: forgot to mention that some people just have a crazy high RMR and can eat that and much more without gaining much weight. Shit’s wild, but the flip side of that is that a lot of parents of kids with high metabolisms get side eyed like they’re starving their kids because they’re not gaining weight.

A lot of it is through liquids. A double gulp or Starbucks drink is a daily routine for most Americans.

Depends what you’re eating. 2000 calories of oreos or soda go down in minutes. 2000 calories of broccoli probably kills you lol
