Nutcase: I couldn't disagree with you more.
Decreasing food intake is one of the hardest things I could imagine doing. I've tried, but the pain in my stomach, the light-headedness, and everything else that comes with eating less than your body thinks it needs feels like suicide. Even just cutting out a small portion of a meal leaves me unsatisfied and itching for more.
On the other hand, exercise (though boring) is easy. I can play softball, bike to work, or walk to the corner store without too much trouble. That's not to say I do it often -- after all, I'm lazy -- but it's a lot easier than trying to starve myself.
Also, I don't think you understood what he meant about motivation. No, you don't need motivation to lose wait -- you just need to burn more than you consume -- but without motivation, you'll have an awful time actually doing any exercise. That's why I don't exercise -- I can't be bothered. Yes, I should. Yes, I wish I would. But the motivation to fit into my clothes and not be so tired isn't as strong as the hatred of wasting an hour, exerting myself, and getting sweaty. It may seem trite, but that's how it works. If I was more motivated (say, I thought I was going to die, or somebody was willing to pay me a lot of money to lose some weight), I would sure as hell get off my ass and workout. Motivation doesn't cause you to lose weight; it causes you to work out, which causes you to lose weight.
