Define basal metabolic rate and give one short worked example.

# Basal Metabolic Rate (BMR) **Definition:** Basal Metabolic Rate is the number of calories your body needs to perform essential life-sustaining functions while at complete rest (breathing, circulation, cell production, nutrient processing, etc.). It represents the minimum energy required to keep your body functioning if you did nothing but rest for 24 hours. ## Worked Example **Problem:** Calculate the BMR for a 30-year-old woman who weighs 65 kg and is 165 cm tall. **Solution:** Using the Mifflin-St Jeor equation for women: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) - 161 BMR = (10 × 65) + (6.25 × 165) - (5 × 30) - 161 BMR = 650 + 1031.25 - 150 - 161 **BMR = 1370.25 calories/day** This means this woman needs approximately **1,370 calories per day** just to maintain basic bodily functions at rest, before accounting for any physical activity.
