I think a lot of overweight people overestimate how much they eat and vice versa. I always thought I ate a decent amount until I looked up the recommended calories vs the calories I was getting. If I'm not working out and trying to get bigger I rarely eat over 1000 calories in a day lol. Not sure how some people have such big appetites. I really gotta force feed myself to get over 2000 cals and I should be getting between 2500 and 3000.
