Counter Counter Is Useless

By Dr. Eva Reynosa


Throw out your calorie counter. Ignore the calorie count on food labels. Counting calories is a simple-minded and useless way to judge what you eat. Why? First off, a calorie is a unit of heat. Heat is not directly useful metabolically. Once a calorie is released, there is no putting it back.

A calorie is simply how much heat it takes to raise a cubic centimeter (milliliter) of water by one degree Celsius, starting at room temperature and at sea level. Saying that you can eat calories is like saying that you can eat heat.

Health professionals, trainers, nutritionists, and many other experts who ought to know better, wrongly equate food calories to metabolism. This is based on simple-minded reasoning that says calories from food provide you with energy. This is incorrect!

Since calories are simply a measure of heat, you can see why they have nothing directly to do with metabolism. Calories effect temperature, so they really only help keep your body temperature where it should be.

Do you realize how food calories are measured? We completely incinerate the food in a lab instrument called a bomb calorimeter. When a substance is completely burned up, until nothing except its charred remains are left, it has lost all the calories that it contained. When this is done in a bomb calorimeter, the amount of heat that is released is expressed as calories.

In a bomb calorimeter, carbohydrates yield 4 calories per gram, proteins yield 4 calories per gram, and fats yield 9 calories per gram. However, it is nonsense to suggest that these food groups provide you with anywhere near the amount of heat that they yield in a bomb calorimeter. You can see why the whole business of keeping track of food calories, as measured in a bomb calorimeter, for weight loss is so misleading as to be ridiculous.

If your body was really like a furnace, then the calorie count of foods, such as on nutrition labels and in food lists, would have more meaning. Your body, however, has nothing to do with how a furnace works.

In the first place, you can only harvest 10 or 20 percent of the calories from food, maybe up to 30 percent on the high end. Some foods will yield no calories at all, regardless of what they yield in a bomb calorimeter. A calorie counter does you no good whatsoever in evaluating different foods for their metabolic value.

Consider this comparison: starch vs. cellulose. Cellulose is indigestible fiber, whereas starch is a source of food energy for humans. However, gram for gram, they both yield the same exact number of calories in a bomb calorimeter.

Similarly, your body gets plenty of caloric value from potatoes and almost nothing from celery. However, in a bomb calorimeter, they would yield comparable calories per gram.

Instead of comparing food metabolism to a furnace (calorimeter), it is vastly more meaningful to understand the fate of different foods upon digestion. This entails how they impact different kinds of cells and tissues, such as fat vs. muscle, and what happens to these tissues because of different foods.

For a surprising example of what this means, compare the two nearly identical sugars, glucose and fructose. Following their metabolic fate is much more meaningful regarding their roles in diet and health than just keeping track of counting calories that they yield in a bomb calorimeter. In fact, these two sugars have identical caloric potential, 4 calories per gram. However, glucose goes into many different tissues, most notably muscle and brain, and intact fructose never escapes your liver.

The consequences of these differences are that glucose serves the metabolism of your entire body, whereas fructose has to be converted to something else before you can do anything with it. That something else is largely fat. In simpler terms, fructose will make you fat much faster than glucose will. Their caloric potential is irrelevant.

By the way, you will be clearer about the uselessness of calorie counts for losing weight once you grasp the difference between calories and metabolism. Chew on that notion for a while (pardon the pun). This is the clarity of thinking that will guide you to a lifetime of success in whatever weight management or fitness program that you pursue.
