What is basal metabolic rate?
Basal Metabolic Rate (BMR) is the minimum amount of calories the body consumes to sustain life in a state of complete rest. It accounts for 60 to 751 calories of the total daily calorie expenditure.
Comparison of two formulas
Mifflin-Saint George (more accurate, currently recommended):
Male: 10 × weight + 6.25 × height − 5 × age + 5
Female: 10 × weight + 6.25 × height − 5 × age − 161
Harris-Benedict (traditional formula):
Male: 88.362 + 13.397 × weight + 4.799 × height − 5.677 × age
Female: 447.593 + 9.247 × weight + 3.098 × height − 4.330 × age
Male: 10 × weight + 6.25 × height − 5 × age + 5
Female: 10 × weight + 6.25 × height − 5 × age − 161
Harris-Benedict (traditional formula):
Male: 88.362 + 13.397 × weight + 4.799 × height − 5.677 × age
Female: 447.593 + 9.247 × weight + 3.098 × height − 4.330 × age
How to increase basal metabolic rate
- Increase muscle mass through strength training (BMR increases by approximately 13kcal per 1kg of muscle)
- Maintain sufficient protein intake (dietary thermogenic effect)
- Sufficient sleep (BMR decreases due to lack of sleep)
Frequently Asked Questions
What is basal metabolic rate?
Basal Metabolic Rate (BMR) is the minimum amount of calories the body consumes to sustain life when in a resting state without doing anything. It accounts for 60 to 751 calories of the total daily expenditure.
Which formula is more accurate?
The Mifflin-St. George formula is currently considered to be more scientifically accurate. The Harris-Benedict formula is an older formula developed in 1919 and tends to overestimate modern people.
How can I increase my basal metabolic rate?
Increasing muscle mass is the most effective method. Since muscle consumes more energy than fat, building muscle through strength training raises your basal metabolic rate. Consuming sufficient protein and getting enough sleep are also important.
