How the body uses food as energy?
The human body is incredibly complex. Every second, millions of chemical reactions happen to good health. The body creates things: heat, muscle, protein, hair, nails, fat, bones. And also breaks things: food, stored fat, and so on. These processes, together with all the organs and systems, they need fuel to perform all these functions. And the energy the body uses comes from what we eat and drink in our diet. In short, food is human gasoline.
Understand how food is used, how to burn those calories, how nutrients are absorbed among other things is very important to learn how to lose weight and eventually control it. It is important to know how come our calories, and also as burning.
The digestive system helps to absorb the energy and nutrients from food. Carbohydrates, fats and proteins are digested differently, but any excess of these three nutrients are converted into body fat and adipose tissue.
The body follows a priority order to burn fuel. And the fuel comes from protein, carbohydrates and fats. However, the exact mix that our body uses depends on the circumstances (our physical activity, our last meal). There is a “priority” that dictates which fuel is burned first. The first is protein, then fat. In practice, however, typically burn a mixture of carbohydrates and fats, depending on the quantities of each meal. If we exercise immediately after meals primarily burn carbohydrates instead the more distant we are eating (and obviously depending on the type of exercise we do) will burn more body fat.
According to experts, if we can not burn all the fat you consume, the rest is accumulated as adipose tissue. This “ability to burn fat” is determined in part by the amount of insulin in our bloodstream (a factor that strongly influences insulin release is the glycolic index, which is a measure of the amount of insulin releasing carbohydrates) . When levels are low, primarily burn fat. When are high, we burn carbohydrates.
