Meal Frequency and Glycemic Control in Individuals With Type 1 Diabetes

This group will follow a dietary prescription consisting of three meals per day. The total energy value will be distributed in accordance with the macronutrient recommendations for type 1 diabetes (T1D), as follows: 45% of energy from total carbohydrates, prioritizing those with a low glycemic index; up to 30% from total fats, with unsaturated fats being the primary source; and 25% of energy from proteins. Caloric distribution will be divided into 30% for breakfast, 40% for lunch, and 30% for dinner, with 14 g of fiber per 1000 kcal distributed across the three meals. Furthermore, the gram amounts of the macronutrient in each meal will be apportioned such that 15-20% of the total carbohydrate intake, 7-10% of the total protein intake, and 10% of the total fat intake.Participants will also be instructed to maintain their habitual physical activity level.

This group will follow a dietary prescription consisting of six meals per day. The total energy value will be distributed in accordance with the macronutrient recommendations for type 1 diabetes (T1D), as follows: 45% of energy from total carbohydrates, prioritizing those with a low glycemic index; up to 30% from total fats, with unsaturated fats being the primary source; and 25% of energy from proteins. Caloric distribution will be divided into 20% for breakfast, 10% morning snack, 30% for lunch, 10% afternoon snack, 25% for dinner and 5% bedtime snack, with 14 g of fiber per 1000 kcal distributed across the three meals. Furthermore, the gram amounts of the macronutrient in each meal will be apportioned such that 5-10% of the total carbohydrate intake, 2-7% of the total protein intake, and 2-8% of the total fat intake.Participants will also be instructed to maintain their habitual physical activity level.
