My method relies heavily on the Glycemic Index. They haven't yet introduced the concept of Glycemic Load, but it will come sooner or later. In the meantime I can take it into consideration myself.

The principle is pretty simple. First you eliminate all refined foods, sugar, white flour, potatoes, corn etc. For each of your meals you choose one of the following combos. Protein/Fat/non starchy veggies OR Low Glycemic carbs/veggies/low-fat. That's pretty much it in a nutshell.

Example: Breakfast : Eggs or ham/bacon OR Whole-wheat Bread with no sugar jam.

Lunch : Whole wheat spaghetti with low fat tomato sauce, side salad. OR Atkins type lunch
