The cheapest I've found works the best for me. Eggs/chicken breasts/tuna, favorite low carb protein powder, as many raw vegetables and fruit as you want. I wouldn't eat 6 pounds of blue berries every day but it's hard to over indulge calorie wise when everything is raw.

Also try to have that last meal 2-3 hours before bed and if you can get in a light workout before bed like a walk, 20 minutes of jump rope, etc. Burning off those last calories before sleep works wonders for me.

I completely avoid dairy (don't even do protein shakes) and keep aas at a decent level (400 mg of test give or take) to help spare the muscle tissue. It takes a week or 2 to get used to this diet but the effect is dramatic. I can drop 30 pounds in a month easily.
