Will Calories Make You Fat?

Will calories make you fat? That almost seems like a trick question with and obvious answer. Apparently the answer isn't as obvious as it seems. I saw an article on the internet recently that made the claim that "calories don't make you fat." My first reaction was "Try to get fat without them."

Although the author of that piece apparently did not know enough of what he was talking about to give a rational explanation of that claim - I think he actually thought he was correct - there is a sense in which the statement could stand as true. Calories per se do not make you fat. It is an excess of calories that makes you fat. But it is still calories that make you fat.

The author seemed to be confused about the fact that a calorie is simply a measure of available energy. That much is correct. But if you are going to look at it that way, you need to finish the equation and consider that fat is simply excess energy in storage. In fact, that is just what fat is. So will calories make you fat? As long as excess calories, or excess energy - if you want to insist on that definition, is stored as fat, Yes! Calories in excess will make you fat.

The question is: What is excess? How do you know when you are putting in more energy than you are using? Come on, now. You have a mirror. You can see the stored energy. Don't fuel your moped like it was a stock car.
