You advocate a starvation diet. You willingly admit that once the muscle is gone it will eat through the fat. Yet the part you're not understanding is as you get smaller, you will still look fat. You'll even look fatter as there is no muscle to hold the fat in around your stomach making you look bigger than you really are.
Basically I agree with the less calories part. I disagree with saying eating 800 calories a day will get you what you want. You'll still look fat, you'll just be smaller. That's the point I've been trying to make.
This part is not directed to you but, it's amazing how smaller people think it's so easy to lose weight. I've been battling weight loss for over 5 years now. I'm still trying to lose weight.
