Obesity is a very serious problem at the 21^st Century essentially affecting developed countries. It may be considered a pandemicity. Among predisposing factors for obesity here are, on the one hand, the new feeding habits with fat-and carbohydrate-rich pre-cooked foods, and in the other hand sedentary lifestyle due to occidental society lifestyles. Although obesity is considered a chronic disease, it would really represent a normal and physiologic adaptation mechanism to an "obesogenic" environment. Bariatric surgery represents a solution for morbid obesity when all the other conservative measures have failed, achieving the modification of nutritional habits and nutrients absorption. However, it is paramount to modify lifestyle concerning sedentary lifestyle. Individualized exercise monitoring offers the advantage of motivating and rejection to exercise. It is necessary to study and assess the efficacy of aerobic and anaerobic physical activity at both pre-surgical preparation and further course of these patients.
