I like having hard rules to follow, makes cheating less of a slippery slope.
I agree that if your going to over eat or underestimate calories ... starch will be the enabler.
I think I'm at the point where I'm not looking to loose any more mass, dropped from 230lb-200lb at 6'4". Now I'm finding that its a lot more work to build muscle than it is to lose weight.
When I was in middle years I lost weight fast. I ate very small portions of what ever Mom was making and was excercising and lifting weights. Lost 65 pounds in about 4 months. Managed to keep it off until I went to university, gained some back and then started doing the same thing and lost the weight again. I started my professional job and for the first two years of work I was buried and ate too much and did too little. 10 years later I was the heaviest I ever was. I started the Dukan diet in late Fall and lost a little weight and then fell off the wagon. I tried it again in February and really tried to stick to it. I am down nearly 40 pounds.
The wife still eats starches and so I still get cravings. I really crave fruit, pineapple, apples, and bananas.
