BMR Equation:
| From: | To: |
The BMR (Basal Metabolic Rate) equation estimates the number of calories your body needs to perform basic life-sustaining functions at rest. This calculation helps determine your daily caloric needs for weight management.
The calculator uses the BMR equation:
Where:
Explanation: The equation calculates your basal metabolic rate based on your weight, height, and age to determine the minimum calories needed for basic bodily functions.
Details: Knowing your BMR is essential for creating effective weight management plans, whether for weight loss, maintenance, or gain. It forms the foundation for calculating your total daily energy expenditure.
Tips: Enter your weight in pounds, height in inches, and age in years. All values must be valid (weight > 0, height > 0, age between 1-120).
Q1: What is Basal Metabolic Rate (BMR)?
A: BMR is the number of calories your body needs to maintain basic physiological functions while at complete rest, such as breathing, circulation, and cell production.
Q2: How is BMR different from TDEE?
A: BMR represents calories burned at rest, while TDEE (Total Daily Energy Expenditure) includes all calories burned through physical activity and digestion.
Q3: What factors affect BMR?
A: Age, gender, weight, height, body composition, and genetic factors all influence your BMR. Muscle mass increases BMR while fat decreases it.
Q4: How often should I recalculate my BMR?
A: Recalculate whenever you experience significant weight changes (±10 pounds) or every 6-12 months as part of regular health assessment.
Q5: Can I use BMR for weight loss planning?
A: Yes, BMR helps determine your maintenance calories. For weight loss, create a calorie deficit by consuming fewer calories than your TDEE while ensuring you meet nutritional needs.
