Scientists and nutritionists have for years searched for ordinary patterns in food habits and the human figure. In this area, developed a set of theories and hypotheses, but in the middle of the last century, experts managed to establish this relationship, which is based on parallels between metabolism, eating habits, and figure. It was found that it is possible to make out quite logical patterns between nutrition and the general state of health. In accordance with the characteristics of metabolism, all people can be divided into groups, where to allocate those interested in vegetable diet, those who may feel good on the protein diet, as well as those who are in dire need of a balanced diet. Good results in this study were able to make George Watson, that he owned the greatest achievements in this field.
