BMI

Body Mass Index measures your body weight relative to your height. It's a useful screening tool for weight categories.

Underweight: < 18.5
Normal: 18.5 - 24.9
Overweight: 25 - 29.9
Obese: ≥ 30

BMR

Basal Metabolic Rate is the number of calories your body needs to perform basic functions like breathing and circulation while at rest.

Uses the Mifflin-St Jeor equation:
Men: 88.362 + (13.397 × weight) + (4.799 × height) - (5.677 × age)
Women: 447.593 + (9.247 × weight) + (3.098 × height) - (4.330 × age)

Daily Calories

Total daily energy expenditure based on your BMR and activity level. This helps determine your calorie needs for weight maintenance.

Sedentary: BMR × 1.2
Light active: BMR × 1.375
Moderate: BMR × 1.55
Very active: BMR × 1.725
Extra active: BMR × 1.9
