Basal Metabolic Rate (BMR)
BMR is the number of calories your body needs to accomplish its most basic (basal) life-sustaining functions like breathing, circulation, and cell production.
Think of it as the calories you would burn if you stayed in bed all day.
Simplified Estimate:
BMR \approx \text{Weight (kg)} \times 24 \text{ hours}
?FAQs
Does BMR decrease with age?
Yes, as muscle mass tends to decrease with age, BMR also slows down.
