Millions of words have been written and spoken about overweight. By now everybody knows everything about it – except what causes it and how to get rid of it. Do you believe that overweight is just a result from overeating? This is one of many assumptions we have taken for granted over the years, one of the many myths of the problem of being overweight. The first diet books by doctors and dietitians told as that losing weight is just about adjusting your calorie intake and eating a balanced diet. Adjusting your calories and a balanced diet is not the answer to the overweight epidemic. To understand overweight problems you must understand metabolic rate and the function thereof. Metabolic imbalances are one of the main factors in gaining weight and not being able to control weight loss.
