Ultra-processed foods reduce fullness signals because they require less chewing and are engineered to taste irresistible, so you eat more calories before feeling satisfied. Ben Greenfield explains why total calories still matter for weight loss, even if junk food makes it harder to stop eating.
Even if we shove all of the concerns aside and say there's no research at all on deleterious effects from a toxicity standpoint, there is absolutely no doubt that because you do not feel as full as fast when eating these ultra processed foods, because you don't have to chew them as much, they just go in and out of your mouth more quickly, they're hyper palatable, you tend to eat more, People tend to eat more. And this is not just me saying it's based on research. When they have a diet high in ultra processed foods, really the biggest contributor to whether or not you're going to lose weight is how many freaking calories, you know, regardless of the food quality. Like, I could get somebody to lose weight Drinking 2000 calories of coca Cola a day, as long as they're burning like 2100 calories a day. I'm not endorsing that. I don't think it's healthy.
