Even the guy who was the low-carb guru said his diet was unbalanced. I did it, and it's right in the front of his book. He said all diets are unbalanced (low-fat, no-fat, low-carb, etc. etc. etc.) and that's why people lose weight on them.
His point with his diet was that you could eat all you wanted of no-carb food, and in moderation of low-carb food.
But it's UNBALANCED. Your body isn't getting the nutrients it needs. That's why people can't maintain the weight loss on those diets. They are starving and they finally break. There is one way to weight loss that works for good: eat less, move more. Period.
I think raw is probably the best way to go, but I know people who can't handle totally raw. They get bursitis. So they do a combo of raw/steamed. The truth is, we have to listen to our bodies. People aren't real good at that. I would suspect some people could eat meat until the cows come home. (Sorry) But, and I'll tell this story again, we have a friend who says he feels absolutely terrible when he eats meat. I don't feel anything at all, but when I eat any of the grasses: wheat, rice, sugar cane, oats, etc., I feel horrible, heart races, skips beats, blood pressure goes to the moon.
Mostly people would just do better if they ate real food. Shop the outside of the supermarket if you can't do farmer's markets or grow your own. I read a great thing last night: food shouldn't have labels. If it has a label, it's not real. Pretty easy to figure that one out when we shop for food, eh?
