I don't understand. Are you trying to bulk up? Are you trying to lose weight?
You never really mentioned your goals.
As for bulking up (which seems to be the case, mentioning all the protein), I would actually advise against this. Becoming musclebound can actually hinder later exercise. Plus you can overdo protein and gain weight. But I probably can't tell you not to, so instead I'll say this.
Diet works in conjunction with exercise. A high protein diet that you you get from supplements and such, you need to burn the proteins in order to turn them into muscle. If not, your body does catabolism
that is, it kinda eats itself. Either it turns it into fat, or you simply don't gain muscle mass. With my brother moving to Texas, it kinda did the first one. Pump weights, but also do some walking so your body isn't rigid with muscle.
For leaning your body out, I strongly recommend grains (not breads or grain products, by grains I mean oatmeal, rice, bulgur wheat, that sorta thing), and sources of vegetable fiber. Avoid trans fats and artificial chemicals. And again, exercise. This time, run/walk instead of lifting weights. Do a few situps and pushups and exercises to improve flexibility, and run/walk regularly. Here's a trick someone at track taught me. It's tempting to do the Gatorade approach afterwards, but this creates a kind of sugar spike. Instead, do a cooldown walk up to 30 minutes after a run. Your body creates some lean muscle, and your metabolism is alot better than trying to pump it with sugar. It will need water and electrolytes, but the latter you get from food.
Remember, Atkins is not a solution for weight loss. It works at all because of the catabolism factor. And because of lack of varied nutrients (the same way giving up milk would cause weight loss, it isn't that milk is bad, it's the nutrient variety absence).
