Dieting Myth: Fat Loss Controlled by Calorie Types

By Stephen Bartlay

It's all over the Internet . . . this crazy idea that calories come in "types."

I've seen an article that actually classifies the calorie types. This person would have us believe that there are fat calories, carbohydrate calories and protein calories. Another warns you of the woes that may befall you if you don't know your "calorie types."

Frankly, in reading this stuff, I'm not sure whether to shed tears of laughter or of pity.

A calorie is a measurement. It is a precise amount of energy. Specifically, it is the amount of energy required to raise the temperature of 1 gram of water 1 degree Centigrade.

Pounds don't come in "flavors", inches don't come in "colors" and calories don't come in "types." To talk like this just wouldn't make any sense (except perhaps in poetry).

We can however, talk about things like the amount of energy in food. We can also talk about the amount of energy you burn when you perform some task, such as walking, raking leaves of shoveling snow.

In either case, we would talk about these energy amounts in terms of calories.

Different foods contain different amounts of energy. In the same way that it takes way more feathers to make a pound than it does of coal, it takes way more celery to hold 200 calories than it does of chocolate.

This sort of "food science" is the basis for some diet programs. It should also be one of the cornerstones of your lifestyle eating strategy. When we say we feel "full", one of the things involved is this idea about the amount of food compared to the amount of calories. There is more to it than just this, but we can"t go that deep in this article.

But I can say that the relationship between volume of food and number of calories is very important when it comes to weight control. If we can find foods that supply large quantities but small numbers of calories, we stand a better chance of feeling satisfied while not gaining (and maybe even losing) weight.

The notion that there are "types" of calories needs to be replaced with the idea that different foods contain different amounts of energy.

And we now know that to lose fat, we need to burn more calories than we eat. - 16955
