BMR is the estimated amount of energy which the body burns in resting state to maintain normal bodily functions like breathing, digestion, and heart rate (HR). BMR ( Basal Metabolic Rate ) is used to determe a person’s total daily energy expenditure, which takes includes person’s physical activity level ( Calories burned due to daily physical activity) in addition to their BMR.
BMR equation is as follows:
For Men ( Adult) : BMR ( Basal Metabolic Rate ) = (10 * weight in kg) + (6.25 * height in cm) – (5 * age in years) + 5
For Women( Adult) : BMR ( Basal Metabolic Rate ) = (10 * weight in kg) + (6.25 * height in cm) – (5 * age in years) – 161
The equation is then finally multiplied by a physical activity factor to derive estimated total daily energy expenditure.
It’s important to note that BMR ( Basal Metabolic Rate ) values are just an estimation, and it may not be accurate for everyone. Many other Factors such as muscle mass, body composition, and genetics may also play a role in a person’s BMR. Additionally, BMR ( Basal Metabolic Rate ) also changes with age, hormonal changes, illness, and other conditions, so it’s important to regularly evaluate your BMR if you notice any changes in your body.
Knowing your BMR might be a helpful tool when trying to lose weight or gain weight. By analysing your minimum Daily calorie consumption you can fix your daily calorie intake accordingly. To lose weight your daily target calories intake should be less that your daily calorie requirement while to gain weight your daily calorie intake should be higher than your estimated daily calorie requirement.
