The role of green tea on the body composition of obese sedentary subjects
Abstract
Introduction: Food with functional properties promote nutrition and various health benefits, such as reducing the appearance and control of chronic diseases, such as obesity. The World Health Organization estimates that in 2015 the population of obese people in the world will reach 700 million people, do not follow his recommendation to increase physical activity and diet control. Objective: To review the scientific literature on the properties, effects, dosage, form, and mechanisms of action of green tea on change in body composition in obese sedentary. Literature Review: Green tea has been widely used by people to weight loss. Several studies have shown that green tea and its components are capable of, among other benefits, to promote thermogenesis, decrease body fat and lipid oxidation, helping to prevent and treat obesity and its comorbidities. The main mechanisms of actions reported relate to epigallocatechin gallate and caffeine, which perform actions on the sympathetic nervous system by inhibiting key enzymes involved in the process of thermogenesis and lipid oxidation. Conclusion: Green tea promotes, among other benefits, change in body composition in obese sedentary. However, the dosage and form of presentation are not yet defined and the mechanisms by which tea exerts on the body yet to be further clarified. Therefore, we need more studies to clarify these points.
