The calorie theory says that weight management in humans is a simple matter of calories-consumed vs
calories-expended. It is suggested that this is a matter of the second Law of Thermodynamics which
states essentially that energy is conserved in a closed system, in other words, all calories have to
be accounted for, none is *created* and none is *lost*.
The flaws in this theory:
1) The human body is not a closed system. Duh!
2) The theory assumes that *all* food that is consumed is broken down *completely* into energy, in
its *entirety*, in *all* circumstances, at *all* times. This is an incredibly absurd assumption.
This theory ignores the fact that each of the three macro-nutrients, fats, proteins and
carbohydrates, are metabolized differently and used to various degrees for tissue rebuilding and
energy needs in different ways at different times depending of the state of the body.
Each nutrient breaks down differently and each nutrient affects various hormones and in turn may
affect how the body uses the nutrients in various states of hunger or satiety. The amount and
quality of the food itself changes the metabolism on an on-going minute by minute basis.
The second Law of Thermodynamics does not apply to weight management in humans.
I challenge anyone to provide us with the name(s) of the researcher(s) or scientist(s) who showed
beyond a doubt that the 2nd Law of Thermo applies to the human body and give us the names of the
study or study that first proved it.
This is the very foundation of our nutritional beliefs. Something as fundamental and as crucial as
this is to the nutritional sciences should be well documented and easy to find.
