This is why you're wrong. Your body needs protien to keep maintained. Your body needs power to keep moving. It can get power in one of two ways: it can eat sugar or it can eat fat.

If you eat limited calories and have, lets say, a 60%c/30%p/10%f diet, your body won't be receiving enough sugar to function during the day. The reason is that after a meal, whatever glucose is not immediately used will be coverted via an insulin rush into fat. When your body suddenly has no glucose to burn, it begins glucogenesis by burning protien. Unfortunately, it is easier to cannibalize your muscles than to convert the free-floating protiens in your body ... which may or may not be used repair the immediate damage that your body is causing. In the end you STILL gain fat and you will find it difficult to gain muscle mass. Your metabolism may slow down due to the lack of primary energy supplies (glucose).

Okay, lets take that one step farther: we REALLY want to do the low calorie thing. Now our body goes into ketosis, so we're burning fat: good deal. Unfortunately, since we're still eating more carbohydrates than we can burn at that time, it all STILL immediately gets stored as fat. If there is a big enough swing, your body will convert back into glucogenisis for a while, but will now break down even MORE protiens from your body. In the end, half the time you're burning fat, and the other half the time you're burning muscle mass and GAINING fat. Now you're really screwed. Your metabolism will drastically slow down due to a lack of your primary energy supply (glucose), making it harder to lose weight and leaving you constantly exhausted.

On the other hand, if you eat 5%c/40%p/50%f your blood sugar will stabilize. No insulin spikes mean that your body won't burn off excess protien or your pittance of carbs via insulin (no fat growth) while constantly burning either your stored or dietary fat for energy. Your muscles don't get broken down, and you do nothing but lose weight. As long as there is still SOME small amount of carb intake your metabolism doesn't slow down because your body's primary energy source is never depleted (ketone bodies).

That is the truth of weight loss and why NO low fat/low calorie diet can EVER work right without extreme effort and/or starvation and why you will ALWAYS gain the weight back: as soon as you start eating more calories again you will instantly gain that weight back because your body is in starvation mode and feels in NEEDS to pack on fat just in case.

Does that make sense to you?
