DIET AND EXERCISE Many people seem to believe that there is a magic diet formula that will guarantee weight loss.[1] This is a fallacy. Most fad diet, if followed conscientiously, will result in weight loss due to thereduction in calories. [2] However, they are nearly always too monotonous and sometimes too unhealthyto be followed in the long term. [3] Worse, fad dieters who don't become physically active and learn toeat sensibly will eventually regain the weight they lost, and often even more. [4] Some of the most popular fad diet in recent years have been low-carbohydrate programs, whichwork by making the body produce ketons. Ketons are normal and efficient source of energy for thehuman body. When the intake of carbonhydrate is severely restricted, body fats are broken down intofatty acids that can be used as fuel. The fatty acids may be incompletely metabolised, yielding ketons.When your body is producing ketons, and using them as fuel, this is called ketosis. Most diets based onketosis do not limit the consumption of protein, fat, or total calories. As a result, their fat content tendsto be very high. Promoters claim that ketosis will lead to increased metabolism of unwanted fat, even ifthe calories are not reduced. This is not entirely true; calorie reduction is likely to occur because of thediet's lack of appealing foods. This is not conductive to forming sensible eating habits. The major widely used low-carbohydrate diet is the one advocated by the late Robert AtkinsM.D, of New York City. Under the Atkins program, the dieter is permitted to eat unlimited amounts ofnon-carbohydrate foods "when hungry". The American Medical Association and many individualexperts have warned that the unlimited intake of saturated fat under Atkins food plan can increase thedieter's risk of heart disease. In 2000, researchers at the University of Kentucky did a computer analysisof a week's worth of sample menus and reported several alarming findings: the diet contained 59% fat; itprovided fewer servings of grains, vegetables, and fruits than recommended by most nutritionists, andwhile it can produce short-term weight loss, long-term use is likely to increase the risk of bothcardiovascular disease and cancer. The weight loss usually doesn't last, either. As ketosis begins,weight will be shed quickly, giving the misleading impression that significant fat reduction istaking place. In fact, most of the weight loss is water rather than fat; the lost water is regained quicklywhen a normal diet is resumed. Appetite, which is often reduced during ketosis, also returns. Atkins advocated his diet for more than 30 years and claimed that more than 60,000 patientstreated at his centre had used his diet as their primary protocol for losing weight. Yet he never publishedany study in which people who used this program were monitored over a period of several years.Besides the dubiousness of its effects in the long term, the Atkins diet shares another shortcoming of allfad diets: inflexibility. People are different, with different health problems and genetic characteristics,and no single diet is right for everyone. An additional downside to the recent craze for low-carbohydrate diets is that it has encouragedfood companies to market low-carbohydrate foods for people who want to "watch their carbs". Most ofthese foods are much higher in fat than the foods they are designed to replace. "Low carb" advertising isencouraging both dieters and non-dieters to eat high-fat foods, which is exactly the opposite of medicaland nutrition authorities have been arguing for decades. Following a low-carbohydrate diet undermedical supervision may make sense for some people, but a population-wide increase in fatconsumption would be a public health disaster.
