Gah.... I wish I could do that. I'm in far too much love with my pills though
I've never had a kid, but my tummy kinda looks like it. When I was 13-14 I ate a lot of fast food, and unhealthy food. I don't know how much I gained, but I gained A LOT of stretch marks, so I'd guess about 20 pounds. And I'm only 5'5 so it looked like more.
I've heard (through multiple sources) writing down what you eat is the best way to control your diet. You really don't want to write down "1 cheeseburger and about... 40 fries" (<-- My weakness) If I wrote down everything I ate, I would probly be a lot lighter right now.
Most personal trainers will tell you 80% of your weight loss is going to be your diet, then 20% is exercise.
