Some foods can cause your satiety system to go bad and you then feel hungry and consume more food. Not everyone counts calories and says "oh, I've eaten too much today, better stop", some people (like me) actually feel real pain when they are hungry and going hungry lowers you willpower which you need to keep not eating and inflict pain on yourself.

Literally everyone feels pain when hungry. The trick is realizing its perfectly goddamn normal and you don't have to eat a 1000 calorie meal because of hunger pains.

It's certainly more complicated than that. I spent a year and a half trying to be in a calorie deficit, meticulously tracking every calorie and wasn't able to lose weight, because I wasn't able to stay in a calorie deficit long enough.

Recently switched to keto, which has the primary function of lowering insulin levels and reduction of feelings of hunger. And within 2 months I'm 18 lbs down.

It's not simply a matter of Calories in/calories out, the kinds of calories you eat matter. 2000 calories of donuts vs 2000 of beef are vastly different nutrient profiles and you will have corresponding health effects accordingly.
