ZAMORA NAVARRO, Salvador  and  PEREZ-LLAMAS, Francisca. Errors and myths in feeding and nutrition: impact on the problems of obesit. Nutr. Hosp. [online]. 2013, vol.28, suppl.5, pp.81-88. ISSN 1699-5198.

The increase in obesity prevalence cannot be explained by a sudden and generalized change in human genome. It is certainly due to the modification of lifestyle habits and especially of the diet, as well as a lack of physical activity and sedentary living. Changes in the feeding pattern and the subsequent unbalance in the caloric profile of the diet may have had great importance in the occurrence of obesity. The social pressure in relation to the body image, the desire to have a slim body, and the fear to gain weight present in the current society have given way to the proliferation of myths and errors regarding pretentiously weight-losing foods and the appearance of miracle diets and dietary complements with magic results on weight loss. Weight-losing foods such as grapefruit, pineapple, apple, cucumber, wholemeal bread or drinking water while fasting are among the most popular and with less scientific evidence errors and myths. On the other hand, miracle diets cause more harm than good and their success is based on weight loss, but not fat loss, since they initially induce dehydration and a decrease in the muscle mass. The intervention study described here shows, once again, that when someone takes a hypocaloric diet he/she will lose weight and that the supplements tried with a satiating, lipolytic and supposedly weight-losing effect do not modify the weight loss produced by the hypocaloric diet. The main therapeutic tools available to fight against obesity are dietary therapy, which is a must in the program, education and behaviour modification, increased physical activity, to fight against sedendarism, and some pharmacological therapy available. The best solution to all these problems that have a great repercussion on the society surely is the development of wide and prolonged informational and educational campaigns in the field of nutrition.
