BMR Equation:
| From: | To: |
BMR (Basal Metabolic Rate) is the number of calories your body needs to perform basic life-sustaining functions at rest. It represents the minimum energy required to keep your body functioning, including breathing, circulation, and cell production.
The calculator uses the BMR equation:
Where:
Explanation: This equation calculates the basal metabolic rate based on your body's basic physiological parameters.
Details: Knowing your BMR is essential for weight management, creating effective diet plans, and understanding your body's energy requirements. It helps in determining your total daily energy expenditure when combined with activity level.
Tips: Enter your weight in kilograms, height in centimeters, and age in years. All values must be valid (weight > 0, height > 0, age between 1-120). For accurate results, use your current measurements.
Q1: What factors affect BMR?
A: BMR is influenced by age, gender, weight, height, body composition, and genetic factors. Muscle mass increases BMR while fat decreases it.
Q2: How often should I recalculate my BMR?
A: You should recalculate your BMR whenever your weight changes significantly (5+ kg) or every 6-12 months as you age.
Q3: Is this equation suitable for everyone?
A: This equation provides a general estimate. It may be less accurate for athletes with high muscle mass, elderly individuals, or those with certain medical conditions.
Q4: How does BMR relate to weight loss?
A: To lose weight, you need to consume fewer calories than your total daily energy expenditure (BMR + activity calories). A deficit of 500 calories per day typically results in about 0.5kg weight loss per week.
Q5: Should I use BMR or TDEE for diet planning?
A: For diet planning, use your Total Daily Energy Expenditure (TDEE), which is your BMR multiplied by an activity factor. BMR alone represents only your resting metabolic needs.
