Actually that is pretty much wrong. You need your carbs. Whole wheat breads/pasta are good for you if ate in moderation, and potatoes are some of the best foods for you, especially sweet potatoes/yams. They just get a bad wrap because of their high glycemic index. And second, I know we all dont want to here this but, but alot of meats have a high level of saturated fats. The the "good" fat is the mono unsaturated fat found in stuff like peanut butter. Is this going to stop me from eating meat, hell no!
I've been on the body for life and just recently the burn the fat feed the muscle plan, and I have dropped 40lbs over the course of 3 months. And they want you to eat carbs, as long as they are complex carbs(oatmeal, whole wheat bread, fiberous veggies, rice, and yams/potatoes)
The most important thing is to get correct size portions, stay away from simple carbs(sweets, processed food) eat several small meals aday(I try to get 6 in everyday) and get some sort of exercise(the most important part I think).
