Waiting for stomach hunger will be like waiting for the “E” (empty) on the automobile fuel gauge. Your normal blood sugar after a meal ranges from 80 to 120 milligrams per hundred deciliters of blood. When your blood sugar level drops to eighty milligrams per hundred deciliters of blood, the hypothalamus (a part of the brain) senses this drop. The brain then sends a message by means of hormones and nerve impulses to the stomach to produce hydrochloric acid, which, in turn produces an empty, hollow, burning, hunger sensation. Your stomach was designed to make and handle this acid production. Acid production, digestion, and absorption of food are all controlled by your nerves (central nervous system) and hormones.
The difference between you and a car is that your body has stored fuel (your fat stores) so that you really do not run out of gas. It should not be scary to go to empty “E”; rather, you should welcome it, for this is how you will lose your excess weight.
