it's easy to gain weight and hard to lose it. It's the same process either way. As I've taught all my children, you can spend an hour on a treadmill and burn 400 calories. And you can then eat a 10 piece chicken McNugget and large fry from McDonald's to consume about 1,000 calories. Add a sugary soda to that and you can blow the vast majority of your daily calories in about 20 minutes. My father never exercised, ate what he wanted, and was always skinny There are definitely multiple factors in play but the #1 factor is how much you eat. I have two sons; one is extremely skinny and the other is overweight. Not coincidentally, the skinny one "eats whatever he wants" which isn't much at all. My overweight son thinks nothing of eating 3-4 slices of pizza for dinner and my skinny son eats 1 slice and he doesn't like cheese so he scrapes that off first.
