BMR Equations:
| From: | To: |
Basal Metabolic Rate (BMR) is the number of calories your body needs to perform basic life-sustaining functions while at complete rest. It represents the minimum energy required to keep your body functioning, including breathing, circulation, and cell production.
The calculator uses the Mifflin-St Jeor equations:
Where:
Explanation: These equations provide an estimate of your basal metabolic rate, which forms the foundation for calculating your daily caloric needs for weight loss.
Details: Knowing your BMR is essential for creating effective weight management plans. It helps determine your maintenance calories and establishes a baseline for creating a caloric deficit needed for weight loss.
Tips: Enter your weight in kilograms, height in centimeters, age in years, and select your gender. For accurate results, use precise measurements and consider that the weight loss calorie recommendation is an estimate that may need adjustment based on your individual metabolism and activity level.
Q1: How accurate is the BMR calculation?
A: The Mifflin-St Jeor equation is considered one of the most accurate BMR formulas for the general population, but individual variations can occur.
Q2: Why subtract 500 calories for weight loss?
A: A deficit of 500 calories per day typically results in losing about 0.5 kg (1 lb) per week, which is considered a safe and sustainable rate of weight loss.
Q3: Should I eat below my BMR to lose weight?
A: It's generally not recommended to eat below your BMR as this may slow your metabolism and cause nutrient deficiencies. Instead, create a deficit from your TDEE.
Q4: How often should I recalculate my BMR?
A: Recalculate whenever your weight changes significantly (5+ kg) or every few months as you lose weight, since BMR decreases with weight loss.
Q5: Does muscle mass affect BMR?
A: Yes, muscle tissue burns more calories at rest than fat tissue. People with more muscle mass typically have a higher BMR.
