Re: When somebody loses weight, where does the fat go?
The entire article never even mentions food, eating, or digestion. The article seems to entirely neglect the central fact that humans need to eat!
The article exclusively examined bodyfat, which might have been useful, except that it ONLY examined the biochemistry of bodyfat, and never even considered the chemistry or the energy involved in the foods eaten in a day. The article carefully analyzed that when bodyfat is metabolized, it creates 84% of carbon dioxide and 16% of water vapor in the exhaled breath.
However, when a daily diet combination of carbohydrates, protein, and animal fat foods is metabolized, the results are quite different, around 71% of carbon dioxide and 29% of water vapor in the exhaled breath.
The reason for that is quite obvious, that various foods contain different combinations of chemical elements and compounds than bodyfat does, especially oxygen atoms, and so the metabolism produces different percentages of waste products.
The article also seemed to claim enormous importance in that 84% carbon dioxide, but it does not seem to make clear WHY that would be important. The scientists around here do not see why there should be any importance of whatever that exhaled proportion is.
In fact, on a day when the person ate just enough food to supply all the metabolic needs of the body, no bodyfat gets used at all. On nearly all days, for most people, the body’s metabolism is entirely supplied by the foods eaten, and in fact, in recent years, many people’s bodies wind up with extra food values which it CONVERTS into additional bodyfat, toward obesity.
That suggests that all the math presented in that article is usually quite wrong on most days for most people. The only exception would seem to be if the person did an absolute Fast for a few weeks, where no foods or juices were consumed at all, such that the entire body’s operation would have used bodyfat for its energy supply. That is rather rare.
Please explain why foods and eating would not be important in such a subject. In contrast, an older article which your notes refer to, at http://mb-soft.com/public3/weight.html , seems to consider all aspects of food and eating, and seems to present more accurate, complete and valuable information.
