When we crave sugar or salt, most of the time what the body really needs (as opposed to wants) is simply pure H2O — pure, clean, unadulterated WATER. In not reading the signal properly, we feed the body precisely what it needs the least of, the same salty or sugary substances that created the deception in the first place. The body becomes even more depleted of water.
An overload of salt or sugar has created a condition of mild dehydration in the body, and the body is asking that its fluid demands be met. We read the signal as wanting more food (usually sugar). Yet, a mere glass of water will satisfy the craving.
I know that this explanation sounds ridiculously simplistic — too easy to be true. Yet, I, and other smart doctors and researchers who have understood the value of water, have recommended water as a cure for food cravings to scores of people with absolutely impeccable results. Unfortunately for all the people who have suffered needlessly, it is only recently that any of us have begun to see the error of the ways of traditional western medical thought in regard to water.
When science began its inquiry into the human body, it followed the basic principles that had been established in chemistry. The 25% solid matter of the body was considered to be the solute, the substances that are dissolved and carried in the blood and serum of the body. The 75% water part was seen as the solvent, meaning that whatever it touches, it begins to dissolve that substance. Following the laws of chemistry and test-tube experiments, it was assumed that the solute composition of the body was the truly important part of the body. The solid materials were seen as the regulator of all bodily functions. The solvent, the water in the body, was seen as a mere space filler whose only function was a means of transport for the important solutes.
This erroneous assumption prevented researchers from even asking the question of whether or not the regulation of the fluids of the body ever go awry. Now that we understand the multiple functions of the solvent, the water in our bodies, we know that the answer is that the fluids in our bodies can and do go awry, and much more often than we would imagine. Most of us have an undiagnosed condition of sub-clinical dehydration. The traditional assumption that we only need to drink water when we experience “dry mouth” is totally false, and is, as well, a dangerous assumption. In fact, dry mouth is the last outward sign of dehydration. Food craving, in particular sugar craving, is a much earlier sign, but one that is not read correctly, and thus not responded to appropriately. So is tiredness. Fatigue can occur when the body is trying to carry out its normal functions on a limited supply of water. Many of us eat when we’re tired in order to get the energy surge that food gives us; what we need, however, much of the time, is just water.
