Understanding Your BMR (Basal Metabolic Rate)
Your Basal Metabolic Rate (BMR) is the number of calories your body needs to maintain basic physiological functions while at rest. These functions include breathing, circulation, cell production, nutrient processing, and protein synthesis.
What Affects Your BMR?
- Age: BMR typically decreases with age due to loss of muscle mass.
- Gender: Men generally have a higher BMR than women due to greater muscle mass.
- Body Composition: Muscle tissue requires more energy to maintain than fat tissue.
- Genetics: Family history can influence your metabolic rate.
- Hormones: Thyroid health and other hormones affect metabolism.
How to Use This Information
Understanding your BMR can help you:
- Set realistic weight management goals
- Create appropriate calorie deficits for weight loss
- Ensure you're consuming enough calories during intense training
- Adjust your nutrition as you age or your lifestyle changes
Note: This calculator uses the Mifflin-St Jeor equation, which is considered one of the most accurate formulas for estimating BMR. For medical advice or precise metabolic measurements, please consult with healthcare professionals.
