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.
