![]() ![]() The number of calories a person needs each day depends on how much physical activity they engage in. ![]() For women: BMR = (10 x weight in kg) + (6.25 x height in cm) – (5 x age in years) – 161.For men: BMR = (10 x weight in kg) + (6.25 x height in cm) – (5 x age in years) + 5.Mifflin-St Jeor Equation To Calculate BMR: The Mifflin-St Jeor Equation has been shown to be more accurate than the revised Harris-Benedict Equation. It was revised in 1984 to be more accurate and was used up until 1990, when the Mifflin-St Jeor Equation was introduced. The Harris-Benedict Equation was one of the earliest equations introduced. How To Calculate BMRīasic formula for calculating BMR (Basal Metabolic Rate): However, it’s recommended to aim for a sustainable deficit or surplus of 500-1000 calories for healthy, manageable weight loss or gain over time. The greater the difference between your calorie intake and your BMR, the faster the rate of weight change. This surplus provides the extra energy needed to support muscle growth, and weight gain.įor example: if your BMR is 1800 calories per day and you consistently consume 2200 calories per day. To determine the calorie surplus required, add 500-1000 calories to your BMR. To gain weight, you need to consume more calories than you burn daily. A sustained caloric deficit leads to weight loss over time.įor example: if your BMR is 1500 calories per day and you consistently consume only 1200 calories per day. This deficit forces your body to tap into its stored energy reserves, primarily in the form of fat, to meet its energy needs. When you consume fewer calories than your BMR, you create a caloric deficit. To determine the calorie deficit required for weight loss, subtract 500-1000 calories from your BMR. To lose weight, you need to consume fewer calories than you burn each day. How Does BMR Affect Weight Loss And Weight Gain? Weight Loss This includes the energy that the body expends to maintain the functions of our body, such as: The BMR accounts for approximately 60-70 per cent of the calories we burn or expend. ![]() You can do this by eating a calorie-dense diet and lifting weights. This means eating more calories than your BMR. If you want to gain weight, you need to create a calorie surplus.You can do this by eating a healthy diet and exercising regularly. This means eating fewer calories than your BMR. If you want to lose weight, you need to create a calorie deficit.Your BMR can help you determine how many calories you need to consume each day to maintain your weight, lose weight, or gain weight. Physical activity accounts for nearly 20% of expenditure, while digestion accounts for about 10%. Genetics: Your BMR is partly determined by your genes.įor most people, the normal daily activity requirement is about 70% of total energy (calories) each day. ![]()
