The number of obese Americans keeps rising. Dieters know that simply consuming fewer calories for a period of time is not always the answer. They go back to their old habits and the weight they lost is regained.
Some scientists are taking a new look at the problem. They are asking what makes us overeat? One possible answer is that it is not the number of calories, but rather the kind of calories we consume
Calories from fat become fat tissue, not muscle tissue. Since we use our muscles for energy we need to eat more to keep going..
Chips, crackers, cakes, soft drinks, sugary breakfast cereals, white rice and bread are refined carbohydrates. Carbohydrates produce insulin in the body. Nobody knows exactly why but insulin triggers a biological craving for food.
Too much of anything is a bad thing. Too much fat and/or too many carbohydrates create conditions where the body desires more food. The body is hungry.
Scientists say the answer is to reduce both the fat and refined carbohydrates we eat.
Experts say our diets should lead us to the body’s “set point” of weight. The set point is the weight range your body is programmed to weigh. Reducing fat and refined carbohydrates should take our bodies back to the set point.
Other experts say food is an addiction. It is a necessary one, but still an addiction. Big eaters must control their addiction.
Scientists say research should focus on the biological and psychological reasons we overeat.
