A startling fact is that carbohydrates are not responsible for making people fat. Don't feel too badly though, you are not the only person who was sold on the idea that a high protein, low carb diet was the only way to lose weight.

Here is a simple way to demonstrate this fact. Think about the vegetarians you know, are there any overweight problems among them? The high protein diets rely on a lot of animal fats and proteins, but these vegetarians don't eat them. Startling indeed, isn't it?

Maybe you don't know any vegetarians. They certainly are hard to find, especially in the Midwest, where I live.

You may wonder about the science involved here. After all, many of those folks promoting the low carb diets are well educated, aren't they? Being well educated doesn't mean that you are infallible. Besides, the same science that supports the low carb diet also supports the high carb diet. They didn't get it wrong, they just didn't consider the whole story.

That might sound like a contradiction, but it isn't. I'm going to explain why in just a moment. Fist, let me give you the science on this. You most likely are not a biochemist or a physiologist and neither am I. But I have studied the subjects a bit. Don't focus on the technical jargon in the next paragraph,just try to grasp the overall point. You don't need to be a scientist to use common sense and basic reasoning skills. Ready?

Consider this bit of biochemistry. Malonyl -CoA exists in high amounts when there is plenty of metabolic fuel present. Thus,carnitine acyltransferase is inhibited and this in turn prevents acyl-CoA from crossing into the cell
