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.
Scientists have a very specific definition of a calorie. The simplest one is that a calorie is the amount of heat that is required to raise a cubic centimeter (milliliter) of water one degree Celsius, at room temperature and at sea level. Saying that you can consume 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 you now know that calories are merely heat, you can understand why the only thing they do is effect temperature. The help with maintaining body temperature, not directly with metabolism.
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.
The maximum amount of heat released from different food groups is 4 calories per gram of carbohydrate, 4 calories per gram of protein, and 9 calories per gram of fat. It is ridiculous to think that these food groups provide you with that much heat. The maximum number of calories from foods, as measured in a bomb calorimeter, is simply useless and misleading when it comes to weight loss.
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.
You can never, ever get all the energy out of food. At the most you might get 10 to 20 percent of the potential energy through your fuel-harvesting metabolism. You will certainly never get more than 30 percent. Sometimes you won't get any calories at all. Using a calorie counter tells you nothing about how your body will metabolize different types of food.
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.
Likewise, a calorimeter will derive the same number of calories from equivalent amounts of celery and potato, after correcting for water content. Obviously, your body could not possibly do that.
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.
It may surprise you, for example, to compare two well-known and nearly identical sugars, fructose and glucose. Their caloric yield is exactly the same in a bomb calorimeter. However, glucose goes through the liver into many different tissues, most notably brain and muscle, and fructose never escapes intact from the liver. Counting calories tells you nothing about these two different metabolic fates.
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, once you understand what is truly important about foods of all kinds, which is clearly not their calorie content, you will be very clear on why calories have nothing to do with being overweight. Chew on that comment for a while (pardon the pun), because this is the kind of clear thinking that will guide you to success in any weight loss or fitness program that works for a lifetime.
