Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Classic IF diet

The 16:8 intermittent fasting model, 45-60% carbohydrates, 10-15% protein, and 25-30% fat dietary model applied.

Group Type EXPERIMENTAL

Diet therapy for Classic IF diet group

Intervention Type OTHER

The 16:8 intermittent fasting model was applied for six weeks. Time restrictions were tailored to fit the participants' lifestyles, with feeding times set between 10:00-12:00 and 18:00-20:00 for all participants. The classic intermittent fasting diet was planned with a macronutrient distribution of 45-60% carbohydrates, 10-15% protein, and 25-30% fat. Additionally, total energy intake was reduced by 500-750 kcal.

Low carb-High fat IF diet

The 16:8 intermittent fasting model, 10-30% carbohydrates and 50-65% fat dietary model applied.

Group Type EXPERIMENTAL

Diet therapy for low carb-High fat IF diet group

Intervention Type OTHER

The 16:8 intermittent fasting model was applied for six weeks. Time restrictions were tailored to fit the participants' lifestyles, with feeding times set between 10:00-12:00 and 18:00-20:00 for all participants.The low carb-high fat intermittent fasting diet included 10-30% carbohydrates and 50-65% fat.Additionally, total energy intake was reduced by 500-750 kcal.
