BMR Equation for Men:
| From: | To: |
Basal Metabolic Rate (BMR) is the number of calories your body needs to maintain basic physiological functions at rest. Knowing your BMR is essential for effective weight loss planning as it helps determine your daily caloric needs.
The calculator uses the Mifflin-St Jeor Equation:
For Men:
\[ BMR = 88.362 + (13.397 \times weight) + (4.799 \times height) - (5.677 \times age) \]For Women:
\[ BMR = 447.593 + (9.247 \times weight) + (3.098 \times height) - (4.330 \times age) \]Where:
Explanation: The equation accounts for differences in metabolism between genders and the natural decline in metabolic rate with age.
Details: Accurate BMR calculation is crucial for creating effective weight loss plans, determining daily caloric needs, and setting appropriate calorie deficits for healthy weight loss.
Tips: Enter your weight in kg, height in cm, age in years, and select your gender. All values must be valid (weight > 0, height > 0, age between 1-120).
Q1: Why is BMR important for weight loss?
A: BMR represents the majority (60-75%) of your daily calorie expenditure. Knowing it helps create an appropriate calorie deficit for weight loss.
Q2: How much should I reduce calories for weight loss?
A: A deficit of 500-1000 calories per day from your maintenance level typically results in 0.5-1 kg weight loss per week.
Q3: Does muscle mass affect BMR?
A: Yes, muscle tissue burns more calories at rest than fat tissue. Increasing muscle mass can raise your BMR.
Q4: How often should I recalculate my BMR?
A: Recalculate after significant weight changes (5+ kg) or every 3-6 months during weight loss.
Q5: Is BMR the same as TDEE?
A: No, TDEE (Total Daily Energy Expenditure) includes BMR plus calories burned through activity and digestion.
