Abstract

As obesity is the epidemic of the 21st century and has become a major public health problem worldwide, being responsible for the vast majority of chronic diseases, a prospective convenience study was carried out on the effect of low-carb and low-calorie diets in people with overweight and/or obesity, at the Centro Hospitalar Universitário do Algarve (CHUA), Portimão unit, at the external nutrition appointment. The study lasted three months. As a result, there is a decrease in weight, Body mass index, fat mass (FM), and visceral fat (VF) in users who had nutritional intervention, with statistical significance (weight (p=0.012), BMI (p=0.012), FM (p<0.001), and VF (p=0.003). In short, concludes that, throughout the appointments, there were statistically significant reductions in weight, BMI, fat mass and visceral fat.
