What may play a factor in the proper nutritional protocol is whether the person is natural or not. A steroid user can look much fuller and still gain muscle and lose fat on a pretty low amount of carbs. I think it's different for most naturals. If you see a lot of (true) natural guys in contests, they look cut but they get very flat. For a natural to diet down and look full, they have to diet down much slower and longer than a user. They probably shouldn't cut carbs below 100 grams a day. Fats can be kept at a decent amount. A juicer can often stay pretty full looking even taking in only 50 grams of carbs provided they up their fats and protein like in the Palumbo diet. Personally, I do the best on about 100 grams of carbs a day, 200 grms protein, fat I don't really count but I get some from egg yolks, oils, and some almonds and of course in some lean red meat. Since I have some good cardio machines in my house, I throw in a couple of cardio sessions a day. This keeps me fairly lean and I weigh almost 200 pounds now at 5'9", natural at 46 years old, where as 10 years ago I would have to weigh 185 to look about the same.
