👉 Diet math involves calculating the number of calories you need to consume daily based on your specific needs and lifestyle factors. This includes considering your basal metabolic rate (BMR), which is the number of calories your body burns at rest, and your activity level, which multiplies BMR to account for daily movements. Using formulas like the Harris-Benedict equation, you can estimate your BMR; then, adjust it based on activity levels (sedentary, lightly active, moderately active, or very active) to determine your daily caloric needs. This math helps ensure you maintain a balanced diet that supports your health goals, whether you're aiming to lose, gain, or maintain weight.
