Basal Metabolic Rate
Definition
Basal Metabolic Rate (BMR) is the number of calories your body needs to maintain basic physiological functions like breathing, circulation, and cell production while at rest.
Scientific / Technical Definition
Basal Metabolic Rate (BMR) is the amount of energy expressed in calories that a person needs to keep the body functioning while at rest. It represents the minimum amount of energy expenditure per unit of time by endothermic animals at rest. The measurement of BMR is usually taken under very restrictive conditions while the individual is in a physically and psychologically relaxed state, in a post-absorptive state (i.e., about 12 hours after the last meal, to ensure that the digestive system is inactive, which requires a high level of resting energy), and at a neutral temperate environment.
Benefits
- Helps determine daily calorie needs for weight maintenance.
- Provides insight into metabolism and energy requirements.
- Aids in the development of personalized diet plans.
Examples
- Calculation through predictive equations like the Harris-Benedict Equation.
- Assessment using tools available at nutritionist clinics.
Additional Information
- Importance: BMR is important for understanding how much energy your body requires at rest, which helps in weight management and designing effective nutrition and exercise plans.
