Intervention 1: Intervention group: Low-FODMAP diet in addition to general recommendations for IBD patients. Firstly, the basal metabolic rate (BMR) of the patients will be calculated using their age, sex, height and weight by the Harris Benedict formula. Then, daily energy requirement of each individual is calculated based on his/her physical activity when considering the thermogenic effect of foods (TEF). The macronutrient composition of this diet includes 55% energy from carbohydrates, 25% from fats, and 20% from proteins. Then, required values ??from each food group will be calculated. In each food group, food items with high FODMAP will be discarded, and the remaining foods will be divided into 6 meals/day, including 3 main meals and 3 snacks. Accordingly, a two-week meal menu will be set up that patients will continue it for two additional weeks (a total of 4 weeks). Intervention 2: Control group: General recommendations for patients with IBD including recommendations to have physical activity, timely disposing of feces, consumption of low-fat dairies and meats, consumption of vegetable oils, and reduction in consumption of refined sugars. |
