While many people are fighting the battle to reduce weight, studies are beingconducted concerning the appetite and how it is controlled by both emotional and biochemicalfactors. Some of the conclusions of these studies may give insights into how to deal with weightproblems. For example, when several hundred people were asked about their eating habits in timesof stress, 44 percent said they reacted to stressful situations by eating. Further investigations withboth humans and animals indicated that it is not food which release tension but rather the act ofchewing.A test in which subjects were blindfolded showed that obese people have a keener sense oftaste and crave more flavorful food than non- obese people. When deprived of the variety andintensity of taste, obese people are not satisfied and consequently eat more to fulfill this need. Bloodsamples taken from people after they were shown a picture of food revealed that overweight peoplereacted with an increase in blood insulin, a chemical associated with appetite. This did not happento average-weight people.In another experiment, results showed that certain people have a specific, biologicallyinduced hunger for carbohydrates subsides. Eating carbohydrates raises the level of serotonin, aneurotransmitter in the brain. Enough serotonin produces a sense of satiation, and hunger forcarbohydrates subsides.Exercise has been recommended as an important part of a weight-loss program. However, ithas been found that mild exercise, such as using stairs instead of the elevator, is better in the longrun than taking on a strenuous program, such as jogging, which many people find difficult tocontinue over a long periods of time and which also increases appetite.
