The Diet Plan Calculator helps you create a personalized nutrition plan based on your age, gender, height, weight, activity level, and fitness goal. Using the Mifflin-St Jeor equation, it estimates your daily caloric needs and recommends a balanced ratio of protein, carbohydrates, and fats. It also suggests a simple daily meal structure with healthy food options to support weight loss, maintenance, or muscle gain. This tool provides a great starting point for planning nutritious meals and achieving long-term wellness goals.
