Why do some people gain weight over time after they lost lots of excess weight?

I've heard that it may have to deal with some hormonal changes or whatnot

it is the protein-carbohydrate balance of the body you should keep within the exercise-eat axis.

When you exercise you burn both proteins and fat. That is what you burn in total. On the after-exercise meal if you don't replace the muscles you've burnt with protein but receive an extra amount of calories to replace them turnig into more fat, you gain weight,

meaning you get fat.

a second thing is that you might be eating a lot of protein so that your muscles are developing while getting denser. In other words, you achtieve a heavy-but-fit-look.

again, you can look fat but weigh less, you can look fat and weigh a world, you can look fit but you are heavy in weight, and you can look fit but weigh less.

Looking both fit and being lesser in weight is probably ideal. And the only way to achieve that is to burn only a little more fat than you receive by eating. Make sure you get some protein right after the exercise, that will help to fix the possible damages on your muscles after working out.

This depends on many different things. It could be a hormonal thing, especially if they are older or if they have a health issue. I have a health issue so my weight fluctuates as my health changes. It sucks because people always complain and talk bad about me behind my back like I am purposely eating bad to gain weight and not taking care of myself. But that's not the case, I have been having problems for 6+ years, so yes weight gain will happen! Sometimes it also stems from the person slipping back into their old habits.

Weight is a hard thing to maintain, and a person has to stick to their lifestyle change in order to get results to stick. That is the hardest part, and why so many people get on this yo-yo dieting cycle.

Metabolism goes down as you get older. Which makes it harder to burn fat. (on your own)

Usually it's an elbow problem. They carry too much food toward their mouth.
