What are negative calories?

It is said that a food contains negative calories when the energy provided is less than that should use the body to digest and metabolize nutrients. That is, if a food provides 20 Kcal but the body uses to digest and assimilate 40 components, has negative calories.

While negative calories are still subject of discussion because it is not scientifically proven its existence, and we can not say that a food contributes -20 kcal, can approach the foods that collaborate when slimming.

That is, although we can not confirm the presence and usefulness of negative calories, if we can use the concept of this term as valid resource for weight loss.

A resource for weight loss

As we said, we can use the concept of negative calories and transform it into a good resource to promote weight loss. Although there are no negative calorie foods, if we consider that some foods more than others claim our digestive work and can even activate our metabolism, allowing us to burn more calories if consumed.

So, we know that our body burns calories to digest and for every nutrient calories consumed are different.

So, when you consume fats required 2.5% of the calories that contribute to digest this nutrient, whereas when you ingest carbohydrates are burned 7% of calories consumed as such and when the nutrient in question are proteins, the body uses 27% of the calories that contribute to metabolize.

So almost no fat protein or carbohydrates, can help our body to burn more calories to digest and thus, can contribute to weight loss. Foods like egg protein is only milk or nonfat yogurt can be quite useful when trying to lose weight.

On the other hand, foods with few calories but high in fiber, also demand more digestive work and therefore can increase caloric expenditure for digestion. This is the case of fruits and vegetables without cooking.

Also, some seasonings such as chili, pepper and mustard have been recommended to stimulate your metabolism and increase energy expenditure that our body has to perform its vital functions. Then, these foods can also help you lose weight if included as part of the diet.

We see then that although there are no negative calories, know your concept can be helpful in losing weight without starving, but eating the right foods to achieve the objective.
