One way to balance macronutrients in a daily meal plan is to follow the 50-30-20 rule, which suggests that approximately 50% of daily calories come from carbohydrates, 30% from healthy fats, and 20% from protein. This framework allows for a well-rounded intake of essential nutrients while accommodating individual energy needs and lifestyles. Adjusting these ratios can help optimize performance, support weight management, and meet specific health goals. Ensuring diverse food sources within each category enhances the overall quality of nutrition.
