don't do it. It will only make your life even worse than it already is. I've been obese my entire life, and I thought that weighing 350 pounds at 18 meant that my life was over so I stopped caring and essentially started trying to commit suicide via food. I peaked at about 500 pounds, but I somehow managed to climb out of the mental rut that I was in and decided that I had to lose the weight.
I'm down more than 200 so far and I've never felt better in my life. I just wish that I hadn't fucked myself up so badly, because even now at 285 pounds I have a shitload of loose skin and I know that once I'm down to a healthy weight I'm going to look like a fucking shar-pei. If at 18 I had decided to lose the weight I know that I would be in a far, far better spot than I am now.
It should be illegal to raise your kids to be fat and I fucking hate my parents because of it. Obviously getting to 500 was my own fault but anyone who has a 200 pound 12 year old should be whipped in public until their kid loses some fucking weight.
