Briefly explain basal metabolic rate and one common misconception about it.

## Basal Metabolic Rate (BMR) **What it is:** BMR is the number of calories your body burns at complete rest just to maintain essential life functions like breathing, circulation, cell production, and temperature regulation. It typically accounts for 60-75% of your total daily calorie expenditure and is measured under strict conditions (after fasting, in a thermoneutral environment, at complete rest). ## Common Misconception **"Eating certain foods or small frequent meals significantly boosts your metabolism"** While digestion does burn calories (the thermic effect of food), the impact is relatively modest—about 10% of calories consumed. No specific "metabolism-boosting" foods create meaningful increases in BMR. Similarly, meal frequency has minimal effect on total daily calorie burn; what matters most is total calorie intake, not whether you eat 3 meals or 6 smaller ones. Your BMR is primarily determined by factors like body size, muscle mass, age, sex, and genetics—not eating patterns or "superfoods."
