For many years the reduction in the dietary fat has been recommended to the population, in order to prevent cardiovascular diseases, obesity, type 2 diabetes mellitus, among other chronic diseases. The consequence has been the replacement of carbohydrates by fat, resulting in the adoption of high carbohydrate diets. However, it has been still discussed if very rich carbohydrate diets should be recommended to the general population. Researches point out controversies about the association between these dietary habits and harmful effects on health and metabolic aspects, such as raise in de novo lipogenesis and triglyceride concentration, reduction in HDL concentration and effects on adiposity. This review evaluates the effects of diet modification, particularly the high-carbohydrate diet, in cardiovascular risk factors such as dyslipidemia and obesity. It also reviews its interaction with physical activity since it is still unknown with which extension it can minimize possible harmful effects of high carbohydrate diets in the long term.
