A Calorie is Not a Calorie
Eat less than you burn and you’ll lose weight – it’s preached as the “be all, end all” of weight loss and it’s completely WRONG.
Truth is, the number of calories you eat is not the only factor that affects your body composition. In fact, there are at least 5 other factors that need to be considered, including:
1.The thermic effect of the food ingested. The thermic effect of food (TEF) measures the amount of energy that is required to support the processes of digesting, absorbing, and assimilating food nutrients as well as the energy expended as a result of the central nervous system’s stimulatory effect on metabolism when food is ingested. Of the three macronutrients, protein carries the highest thermic effect.
2. The fiber content of the food ingested. Due to its chemical makeup, fiber is classified as a carbohydrate; however, it is unlike other carbohydrates in that it is a mostly indigestible nutrient. Even though each gram of fiber contains four calories, these calories will remain undigested and will not be absorbed. Therefore, if one were to consume 300 calories of red beans (a food in which nearly 1/3 of the caloric content is from fiber), approximately 100 of these calories would pass through the intestinal tract undigested.
3. The glycemic and insulin index of the food ingested. The glycemic and insulin index are scaled numbers that refer to how quickly a particular carbohydrate source enters the bloodstream as sugar and how much insulin is needed to rid that sugar from the bloodstream, respectively. Generally speaking, there is a positive relationship between the two; that is, the quicker sugar enters the bloodstream, the more insulin is needed to rid that sugar from the bloodstream. When high levels of insulin are present within the blood, fat burning is brought to a screeching halt, which is anything but desirable for those whose goal is just that.
4. The macronutrients present in the food ingested. Although insulin’s primary function is to shuttle glucose (sugar) into skeletal muscle, it also carries many other nutrients to their respective storage sites; this includes fat. Since carbohydrate ingestion stimulates a large insulin response and fat ingestion gives rise to blood lipid levels, the two, when consumed together in high levels (especially in the absence of protein), promote the greatest fat storage.
5. The timing of the meals ingested meals. Ingesting a large amount of carbohydrates before bed spikes insulin, sabotages overnight fat burning, and increases fat storage during sleep. On the contrary, consuming a great deal of calories early in the day does not bring about this problem; rather, these calories are likely to be used as energy to support daily activities.
As you can see, someone could be eating a relatively small amount of calories daily, but at the same time promoting a great deal of fat storage by:
1) making poor food choices
2) eating carbs and fat together in large amounts without protein, and
3) consuming meals at inopportune times
