As a fellow chonk, if you want a serious answer to what makes you feel full, it's protein and complex carbohydrates (generally stuff with a shitload of fiber).

As a fellow chonk, if you want a serious answer to what makes you feel full, it's protein and complex carbohydrates (generally stuff with a shitload of fiber). As for what's making us bigger, it's cheap and easy access to high-calorie foods that don't make you feel full (generally high simple carb foods like candy, cake, chips etc). A candy bar or can of regular soda is over 10% of someone's daily calorie intake and probably double their recommended sugar intake. And they're everywhere; gas stations, grocery stores, restaurants. I can't remember the last time I was more than 5 minutes away from some massive sugar source. Portion sizes have also gotten out of hand as restaurants competed on portion size to give customers "value". A serving of beef is something like the size of a stack of playing cards. Most restaurants are handing out 2-4x that, and people start to internalize that as how much they should be eating. I think the pricing policies might be effective. Discourage restaurants from competing on caloric content, and make junk food more expensive. Probably not for the current generation, but maybe for future generations the same way as smoking. If your weight is an issue for you, you may want to look at medical appetite suppressants. I've had good luck dieting with my ADHD meds with the appetite suppressing effect (when I'm consistent about trying anyways). Makes dieting a bit easier by taking hunger off the table.
