78 It is now that the eliminative labours of life com- mence and proceed vigorously. Before hunger could be felt, elimination should be complete, and the body should be light. The bowels should there- fore b^cept clean in anticipation of hunger. There are thus several stages in the maturing of hunger :— 1. Emptying of the stomach, indicated by the • escape of a clean wind from the stomach/ through the mouth ; 2. Clearance of the bowels ; 3. A feeling of lightness of the body and an inclination to do work; 4. Physical activity which gives a keener edge to hunger when it is felt; 5* Rest: 6. Bath; 7. Feeling of mature hunger. THE FOUR KINDS OF ERUCTATIONS There are four kinds of eructations through the mouth which we should learn to distinguish from one another. The first one is the clean wind or a series of clean winds which one g6ts in the morning after getting up from bed. This is a sign of the stomach having become empty. Dyspeptics rarely get this more than once in a day. That is why we advise them to take to the one-meal plan. Healthy adults get it not oftener than twice a day/ once in the morning and again in the evening. That is why we say that health? adults should not eat more than two meals in a day. When the stomach is not empty, there can be no hunger; when there is no hunger/ there is no justification for eating.
