I'm not going to read all that, but all I saw was blah blah exercise. Will they even acknowledge that the main contributor to body fat is diet? You can't outrun a bad diet. Those 30-60 minutes of outdoor play won't make up for drinking Coke or similar garbage all day. Actually, exercise mostly just improves the size and fitness of your muscles. If you're doing the stuff that makes your muscles big, it'll make you eat more, and you won't lose fat because of it.
