How to Use the Diet Calculator?

This calculator helps you estimate your daily caloric needs based on your personal information and your goal (weight loss, maintenance, or gain). It uses the Mifflin-St Jeor formula to estimate your Basal Metabolic Rate (BMR) and adjusts this figure based on your activity level.

Enter your gender, age, height, and weight. Select your physical activity level (from sedentary to extremely active) and your goal. Then click 'Calculate My Needs'.
