Do you have a weakness for sweets? Do you feel hungry all the time? Do you eat when you're feeling sad? Do you eat just for the sake of eating? If you do, you do not have an eating problem. You have a brain chemistry problem -- a glitch in your hunger switch. In Turn Off the Hunger Switch, diet specialist Paul Rivas, M.D., shows how the excessive hunger that creates weight gain is a direct result of erroneous brain chemistry messages which turn on your hunger switch. Turn it off, and your hunger -- and weight problem -- disappears. Dr. Rivas's revoltionary no-diet, no-exercise plan places you into one of the following types: You are a type "N" with a norepinephrine deficiency if: You feel tired frequently and blame your fatigue for your weight. Your weight climbs for no apparent reason. You are a type "S" with a serotonin deficiency if: You crave chocolate. You eat out of boredom. You eat large quantities of food at one sitting. You are a type "D" with a dopamine deficiency if: You continue to crave salt or sweets even after various medications have been tried; You are easily distracted. You are a type "C" with a carbohydrate sensitivity if: You can't lose weight even if you have excellent appetite control; Low-calorie diets don't work; You strongly crave mainly carbohydrates like pasta and bread.
