Exercise is to get better condition or get stronger not to loose weight, you can eat in 5 minutes more kcal then you had lost in an hour of exercising, if you want to loose weight you must eat less, reduce the carbs, eat protein, and fat, and you will loose weight doing nothing. Every research done on it proves it to be effective, also you can eat as much as you feel like, you will naturally not crave as much food when eating mostly protein, and fat.
I don't experience any runners high , or any other positive emotional effect that is supposed to be as a result of it, it just makes me tired. I have nothing against movement that doesn't seem like to much effort. I can walk for miles without any problems but I avoid anything that feels like I have to force myself to do it.
I am fat now because I can't care, but I wasn't always fat, and I know that this is about eating the right foods, not those from the obese pyramid that doctors propose. Both from research, and personal experience I actually did take the diet just out of curiosity not because I did care to loose weight I did go from 93kg to 85kg in a month eating as much as I had felt like it. 187cm.
