for fastest weight loss you eat only lean meat, fish, some liver and eggs, ascorbic acid and optionally fiber.

for somewhat slower weight loss you can leave some more fat in by eating full fat steaks instead of lean chicken breasts, and have more eggs and bacon, and eat oranges instead of taking vitamin C.

if you're an athlete who trains for 2+ hours a day you can have some carbs in your diet in form of things like rice. in this case you would have to go back to lean chicken breasts. you can't mix fatty steak and eggs with carbs like rice. one or the other. and again, carbs like rice should only be used by people who do cardio every day !

if you mix carbs and fats - forget it ! it doesn't matter what else you do - you will fail. period.
