Not all calories we eat are the same

Desserts

Although it is not always recommended, many when trying to lose weight or take care of their diet begin to count calories and although 1 Kcal is 1 Kcal, not all the calories we eat are the same, that is, for our body it is not the same to eat 100 Kcal of fat than 100 Kcal derived from protein.

Calories derived from carbohydrates

Carbohydrates have a different effect than fats or proteins in our body, since they are a nutrient that is easily oxidized for energy, and although it can be stored, the body's capacity is limited.

In addition, when we ingest 100 Kcal derived from sugars, insulin in the blood quickly rises, the hormone that is responsible for entering glucose into the cells and that encourages anabolism, that is, the creation of deposits of either glycogen or fat and it preserves the reserves in our body.

While if we ingest 100 Kcal derived from complex hydrates such as whole grains, fresh fruits and vegetables with skin, insulin rises more slowly, we will have energy for longer, we will not have an appetite quickly and the risk of accumulating fat due to The effect of insulin will be less, as there will be no hormonal peak that encourages it.

Calories derived from protein

Proteins are a nutrient that, although it provides the same amount of calories per gram as hydrates (4Kcal), have a totally different effect from them. Thus, if we eat 100 Kcal derived from proteins, for example from egg white, our appetite will be easily satisfied and we will remain without hunger for a long time.

In addition, there will be no insulin spike, our body will work harder and burn more energy to digest and metabolize proteins and this nutrient will not be able to accumulate in case of surplus, because we do not have protein deposits, but we use them to form or repair structures or oxidize and / or dispose of them.

So, although 100 Kcal is 100 Kcal, for our body it is not indistinct that they derive from hydrates or proteins, since the latter will help those who want to lose weight and not accumulate fats much more than those derived from simple hydrates.

Calories derived from fat

Fats are a nutrient more concentrated in energy, that is, 100 Kcal of fat is much less quantity of food and less volume than 100 Kcal of carbohydrates or proteins.

On the other hand, fats are the only nutrient that has the possibility of being stored unlimitedly in our body, that is, we can accumulate and reserve excess lipids throughout the body, affecting the health of the body when, beyond adipose tissue, it is filled with fat the liver, arteries, heart and other vital organs.

As if that were not enough, 100 Kcal of fats do not oxidize quickly, but are the last resort used by the body as a source of energy and also, it does not fill us up quickly as if 100 Kcal of protein can.

All these mechanisms derive from our thrifty genotype that prepares us to reserve and store energy in order to survive adverse conditions such as lack of food.

Conclusion: not only the amount of calories matters

As we could see, not all the calories we eat are the same, because although 1 Kcal is 1 Kcal, in the body it matters where they derive from.

That is, if we start to count calories you have to take into account that not only the amount of calories matters but also the quality of it or where they come from. Well, it is not the same to ingest 100 Kcal of hydrates, that of proteins or fats.
