Frequently Asked Questions
What is BMR and how is it calculated?
BMR (Basal Metabolic Rate) is the number of calories your body needs at rest. We use the Mifflin-St Jeor equation, which is considered the most accurate formula for BMR calculation.
What is TDEE and how does it differ from BMR?
TDEE (Total Daily Energy Expenditure) is your BMR multiplied by an activity factor. It represents the total calories you need per day including physical activity, while BMR is just your resting metabolic needs.
How do I choose the right activity level?
Choose based on your typical weekly activity: Sedentary (desk job, no exercise), Lightly active (light exercise 1-3 days), Moderately active (moderate exercise 3-5 days), Very active (hard exercise 6-7 days), or Extremely active (very hard exercise + physical job).
Is this calculation accurate for everyone?
The Mifflin-St Jeor equation is accurate for most people but may vary for athletes, elderly individuals, or those with certain medical conditions. It's a good starting point for weight management goals.
How should I use my BMR and TDEE results?
Use BMR as your minimum daily calorie intake. Use TDEE to maintain weight, eat below TDEE to lose weight (deficit of 500-1000 calories), or above TDEE to gain weight (surplus of 300-500 calories).
