Basal Metabolic Rate

Definition

Basal Metabolic Rate is the number of calories your body needs to maintain basic physiological functions like breathing and circulation while at rest.

Scientific / Technical Definition

Basal Metabolic Rate (BMR) refers to the rate of energy expenditure per unit time at rest, measured specifically in a thermoneutral environment and in the post-absorptive state, which means that the digestive system is inactive, requiring an overnight fast of 12 hours in humans. BMR accounts for about 60-75% of daily calorie expenditure in most individuals.

Benefits

• Helps determine daily calorie needs.
• Aids in weight management and planning dietary goals.
• Provides an understanding of overall metabolism and energy expenditure.

Examples

• Calculating BMR can help tailor a weight-loss plan.
• Fitness trackers or apps often use BMR to estimate calorie burn.

Additional Information

• Importance: Understanding your BMR is crucial for setting realistic weight management goals and dietary planning, as it indicates the minimum energy requirements to sustain vital body functions.
