Toss out your calorie counter. Pay no attention to the calorie count on food labels. Counting calories is a useless and simple-minded way to decide what you eat. How come? Firstly, a calorie is a unit of heat. Heat does not directly guide metabolism. When caloric heat is released, nothing will put 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!
Now that you know what calories really are (i.e, heat), you can understand that the only thing they can do is effect temperature. They are important for maintaining body temperature, but that is all.
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.
For one thing, you could never harvest all the energy out of food. You might get 10 or 20 percent of it, certainly no more than 30 percent. Sometimes you won't get any calories at all. Using a calorie counter tells you absolutely nothing about what your metabolism will do with different foods.
Think about it. In a calorimeter starch yields the same number of calories as cellulose, gram for gram. However, cellulose is indigestible fiber and starch is a source of food energy for people.
Furthermore, a calorimeter will measure the same number of calories from equivalent amounts of potato and celery (correcting for water content). Obviously, your body couldn't possibly do that.
Comparing the metabolism of food to how a calorimeter (furnace) works is not nearly as meaningful as understanding the fate of different foods when they are digested. It is especially meaningful to understand how different cells and tissues, such as fat vs. muscle, are impacted by 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.
