Has it been easy for you to gain weight? Some people have high metabolisms that make it difficult to put on weight, regardless of what their diet is like. I know my cousin had a very high metabolism when he was a teenager, he could eat a lot of food but never gain an ounce of weight. I have a coworker who has the same issue, no matter how much he eats he barely gains anything. I'm sure that will catch up with him as he ages though. As for me, I do find that it's somewhat easy for me to gain weight.
