BMR Calculation Formula

$$\text{BMR} = 88.362 + (13.397 \times \text{weight in kg}) + (4.799 \times \text{height in cm}) – (5.677 \times \text{age in years})$$ $$\text{BMR} = 447.593 + (9.247 \times \text{weight in kg}) + (3.098 \times \text{height in cm}) – (4.330 \times \text{age in years})$$

Explanation:
The BMR formula helps estimate how many calories your body burns while at complete rest. It depends on your age, sex, weight, and height. The result can be used to plan dietary intake and energy expenditure.

Basal Metabolic Rate represents the minimum number of calories your body requires to maintain vital functions like breathing and circulation while at rest. This is a fundamental metric for anyone tracking calories, adjusting diets, or starting a fitness plan. You can also combine your BMR with your physical activity level to estimate your Total Daily Energy Expenditure (TDEE).
