The Myth of Water Weight Loss

This is a controversy report which I encourage those concern about their weight by using pills to loose water in their body.

Do you know, our body is consist of 70-75% of Water?? Our Brain is consist of 90% of Water??

Do you know that the Water molecules have to be small enough for the cell to carry??

In fact our body have act as a filter system by itself, so in order for the waste to discharge out from the body, there must be enough water as a carrier.

Just as the "I-Medicine Sutra" say, the 5 abstrate elements must be balance in the body, otherwise, illness would form.

So for your great health drink minimum 8 Glass of Filtered Water a day.

The Myth of Water Weight Loss
by Anthony J. Burlay M.D.

There’s a common belief that any initial weight loss on a diet plan comes from lost water weight. It is not clear how this inaccuracy originated. In mammals, including humans, there is no water reservoir sac or gland that empties upon beginning a diet. (Even camels, contrary to popular belief, store fat, not water in their humps.) Where does water in the body come from?

There are two sources: intake and byproducts of metabolism.

The first line of nutrient storage in the human body is glycogen. This is basically a water free glucose polymer stored in the liver and to some degree in muscles. The average liver weighs about 2.5-3.0 pounds. Glycogen usually accounts for about 10% of this weight. This equals less than half a pound. Muscles have about twice the amount of glycogen as the liver, so this is less than a pound or two of total glycogen. Even if all the reserve were converted to water, it would account for less than a pound. (Actually, a chemical reaction called phosporylation breaks down glycogen, not hydrolysis as is commonly believed.) The water molecules that are formed account for only a fraction of the weight of broken down glycogen and are later used for new glucose production.

When fat is broken down, it produces fatty acids and glycerol as its first byproducts. Glycerol enters metabolic pathways to produce energy and glucose molecules, which the rest of the body can use for its energy needs. Fatty acids are chemically converted by oxidation and hydration to Acetyl CoA, which is broken down in other energy and amino acid pathways. These other energy pathways actually use water rather than release it. Even if fat break down were to release an equivalent amount of water per pound, what is the difficulty? Fat gets broken down and weight loss occurred.

What about total body water? The human body has about 42 liters of water. There is a lot of body machinery to keep water at a constant equilibrium. This ranges from thirst centers in the brain, to changing absorption in kidney tubules, to a number of regulatory hormones.

The body is made of 60% water (women have water content closer to 50%). Sixty percent of total water is within cells. Forty percent is in between cells and within blood vessels. Interestingly, more lean people have higher water content than those with a higher total body fat. This is because lean tissue has more water content than fat tissue. Thus, as one loses weight, percentage of water content actually goes up.

Where does the notion about water loss come from? It appears to be from misinformation, not biochemistry and physiology.
