About

Poor eating habits contribute to weight gain and obesity, leading to numerous metabolic issues such as diabetes and cardiovascular diseases. The treatment of obesity involves lifestyle interventions that include dietary and nutritional modifications, physical activity, and behavioral therapy. Literature supports both carbohydrate and fat restriction in the treatment of obesity. In low-carbohydrate diets, less than 40% of energy is sourced from carbohydrates.Besides the dietary model, individual eating behavior can also influence the diet's outcomes. There is a significant relationship between eating behavior and food choices. Given that food choices can impact diet satisfaction, evaluating eating behavior is important when assessing dietary compliance.The literature includes studies demonstrating the effects of a classic intermittent fasting diet. However, no studies have compared the potential effects of intermittent fasting models based on the macronutrient distribution within their content. Therefore, this study aims to evaluate the effects of high-fat, low-carbohydrate intermittent fasting versus classical intermittent fasting on body composition, eating behavior, and diet satisfaction.
