The trap of the energy balance


The trap of the energy balance

Energy can neither be created nor destroyed, only transformed. Sure you have heard before this statement. And it is true, it is the principle of conservation of energy, that is derived from the first law of thermodynamics:
Energy that enters a system = Energy out of system + Variation of internal energy of the system
This is the basis on which is built the theory of energy balance. The theory of energy balance states that, as energy can neither be created nor destroyed, the calories that enter the human body less calories out (expended), are the calories that will accumulate or lose fat:
Calories in - Calories out = Variation of the fatty tissue
But this is a deduction wrong the first law of thermodynamics. The approach of the energy balance equation it is not compatible with the law of conservation of energy or the first law of thermodynamics.
Let's see why.

Do I have slow metabolism?


Do I have slow metabolism?

Sure that on more than one occasion you've heard the expression "slow metabolism". But, does it make sense to speak of a slow metabolism? What factors influence? How can we increase?

To answer these questions let us see first what are the components in which is divided the daily energy expenditure of a person:

The nonsense of the theory of energy balance


The nonsense of the theory of energy balance

The theory of energy balance established from the first law of thermodynamics, that the energy that enters our body, the less that comes out is equal to what is stored in the form of fat.

This statement is true but does not explain the process of accumulation of the fat. The first law of thermodynamics is a universal truth, which is always met, but that has nothing to do with the metabolic processes of fat accumulation.

Does it make sense to count calories for weight control?


Does it make sense to count calories for weight control?

No, it makes no sense to count calories for weight control. The calorie is a unit of thermal energy. Traditionally been used the calorie measure the energy of food ingested and as well to develop diets by applying the energy balance equation: the calories that you ingest less energy expenditure is equal to the fat that is stored.

But this is a serious error, the calories did not influence the body composition of individuals. Scientific studies have shown that diets isocaloric (identical calorie) with same distribution of macronutrients different, have a different impact on the accumulation of body fat.
