Obesity´s rapid rate of growth in the world makes it a major risk factor in this millennium. Between 1980 and 2008 its prevalence has doubled and according to the Latin American Consensus it is directly or indirectly responsible for two hundred thousand deaths each year. High investments in research have enabled science to discover numerous metabolic, genetic and neurological processes, associated with obesity. However, a solution to this public health problem, that affects half a billion people worldwide, still does not exist. Most obese patients seeking treatment have psychiatric disorders, mainly depression and anxiety. There is also a subpopulation of obese patients suffering from eating disorders, such as, Binge Eating Disorder (BED). These co-morbidities may adversely affect the management and conduct of treatment. The aim of this study was to review several publications that relate obesity, binge eating (BE) and BED, highlighting aspects of their prevalence, etiology, and the results obtained from different treatment proposals. This review was compiled from a variety of databases, articles, periodicals and specialized books. The results show that BE and BED have a high prevalence in obese and overweight patients, that there is high co-morbidity of obesity and psychiatric disorders, and that this impairs the results of weight loss treatments. Key Words: Obesity, Binge Eating, Binge Eating Disorder, Weight Loss.

Objectives: To evaluate the importance of a balanced and healthy nutrition associated to regular physical exercise in the prevention of atherosclerosis. Review: Atherosclerosis gradually changed from a chronic degenerative disease model and, exclusively of advanced age patients, to a subclinical chronic inflammatory disease model, already present in childhood. Due to this alarming situation, strategies are being defined for the control of non communicable chronic diseases. One of these strategies would point to a balanced and healthy diet, with an increase in unsaturated fats, and a reduction in saturated fats, which would be beneficial not only for prevention and treatment of atherosclerosis, but also for prevention and control of other associated risk factors, such as arterial hypertension - SAH and diabetes mellitus - DM. Another strategy is the regular practice of physical exercise that can act as a preventive mechanism, since in addition to the improved cardiovascular function, it also promotes significant biochemical and hemodynamic alterations (reduction in arterial pressure, increase in high density lipoprotein cholesterol - HDL - C, reduction in low density lipoprotein cholesterol - LDL - C and in plasmatic triglycerides, and increase in glucose tolerance), which results in the improvement of the health of the individual. Conclusions: Balanced and healthy nutrition associated to regular physical exercise has a great importance in the prevention of risk factors of atherosclerosis development. Key words: obesity, atherosclerosis, balanced diet, physical exercise.

Introduction: The global epidemic of obesity is a combination of genetic and environmental factors. Among the environmental factors, the abundance of palatable foods and calorie low cost is undoubtedly one of the causes that contribute most to the epidemic, which is a gateway to various disorders such as the metabolic syndrome, a complex disorder represented by a set of cardiovascular risk factors, usually related to central adiposity and insulin resistance. Objectives: To reveal the role of exercise in the treatment and prevention of metabolic syndrome. Methodology: Literature review. Conclusions: Physical fitness affects some parameters of metabolic syndrome such as insulin resistance, glucose intolerance and obesity, so should be encouraged for healthy individuals and those with multiple risk factors, provided they are able to participate in a physical training program. Just as clinical therapy helps to maintain the function of organs, physical activity promotes favorable physiological adaptations, resulting in improved quality of life. Key words: Obesity, Physical fitness, Quality of life.
