Your BMR: 0 calories/day
Your TDEE: 0 calories/day
BMR Calculator Guide:
A BMR (Basal Metabolic Rate) Calculator helps you determine how many calories your body needs to function at rest. This means the minimum calories required for essential functions like breathing, circulation, and cell production, even if you do nothing all day. This tool helps you:
- Weight Management
- Fitness Goals
- Health Awareness
- Diet Planning
How to Use the BMR Calculator:
- Select your gender (male/female)
- Input your age in years
- Enter your weight(toggle between kg/lbs)
- Enter your height(toggle between kg/lbs)
- Choose your activity level
- Click "Calculate BMR"
Check Your Result:
The result will show:
- BMR: Calories burned at complete rest
- Daily Needs: Calories for your activity level
- Weight Goals: Loss/gain calorie targets
Note: BMR is an estimate. For exact needs, consult a nutritionist.
Frequently Asked Questions
1. What exactly is BMR?
Calories your body needs daily just to stay alive (breathing, heartbeat, etc.).
2. How is BMR different from TDEE?
- BMR: Calories at total rest
- TDEE: BMR + calories burned through activity
3. Which activity level should I choose?
- Sedentary: Office job + little exercise
- Active: Exercise 3-5x/week
- Very Active: Physical job + daily workouts
4. Why does gender affect BMR?
Men typically have more muscle mass, which burns more calories.
5. How accurate is this calculator?
About 70-80% accurate. Muscle mass and genetics play roles too.
6. How often should I recalculate?
Every 3-6 months, or after significant weight changes.
7. Why does age lower BMR?
Metabolism slows naturally by about 1-2% per decade after 20.
8. Can I lose weight by just eating my BMR?
Yes, but eating slightly above BMR (but below TDEE) is healthier.
9. What if my BMR seems too high/low?
Double-check inputs. Thyroid issues can also affect BMR.
10. How can I increase my BMR?
Build muscle through strength training and eat enough protein.
