If you want to maintain your current weight, it's helpful to know how many calories your body uses. You can calculate the number with a formula that measures your body's caloric needs.
Basal Metabolic Rate
Basal metabolic rate is a measure of calories your body uses when you're at rest. To calculate the BMR for a female, use this formula: 655 + (4.35 x weight in pounds) + (4.7 x height in inches) - (4.7 x age in years). For a male, use this formula: BMR = 66 + (6.23 x weight in pounds) + (12.7 x height in inches) - ( 6.8 x age in years).
Harris Benedict Equation
The Harris Benedict equation is a formula that calculates your BMR with your activity level. This formula determines how many calories your body uses on a typical day. If you're inactive, multiply your BMR by 1.2. If you exercise three to five days a week, multiply your BMR by 1.55. If you're exceptionally active, multiply your BMR by 1.9.
Conclusion
By consuming the number of calories indicated by the Harris Benedict equation, you can maintain your current weight. Weight fluctuations can occur if you increase or scale back your activity level.
