People are overweight for many reasons, the most important one of which is

that they eat the wrong foods, get the wrong types of calories per meal, and they also eat meals at the wrong time each day.

That is the reason why you can eat 1,000 calories per day and not lose any weight, while your friends can eat 2,500 calories per day and not gain any weight.
