BMR Calculator
🔥 What is BMR (Basal Metabolic Rate)?
BMR (Basal Metabolic Rate) is the number of calories your body burns at complete rest to maintain essential functions like breathing, blood circulation, cell repair, and body temperature regulation. It represents the minimum energy your body needs each day to survive without any physical activity.
🧍♂️ Normal BMR Limits for Males and Females
While BMR depends on several factors such as age, weight, height, and gender, here are general average ranges:
| Gender | Age Range | Normal BMR (approx) |
|---|---|---|
| Male | 18–30 years | 1600 – 1900 kcal/day |
| Male | 31–50 years | 1500 – 1800 kcal/day |
| Female | 18–30 years | 1400 – 1700 kcal/day |
| Female | 31–50 years | 1300 – 1600 kcal/day |
💡 Note: These are average estimates. Athletes or people with more muscle mass often have higher BMRs. Older adults typically have a lower BMR due to decreased muscle.
📈 Factors That Affect BMR:
- Gender (males generally have higher BMR)
- Muscle mass (more muscle = higher BMR)
- Age (BMR slows down with age)
- Genetics
- Hormonal conditions (like thyroid issues)
✅ Why Is BMR Important?
Knowing your BMR helps you:
- Understand your calorie baseline
- Plan your diet and fitness goals
- Estimate your TDEE (Total Daily Energy Expenditure) for weight maintenance or fat loss
