What is BMR?
Your Basal Metabolic Rate (BMR) represents the total number of calories that your body needs to perform basic, life-sustaining functions (like breathing, circulation, and cell production). It does not include the calories burned during physical activity. Understanding your BMR can help you set appropriate calorie goals for weight maintenance, loss, or gain.

Energy expenditure breakdown (kcal/day)
Several factors influence your BMR:
- Age: BMR generally decreases with age.
- Gender: Men typically have higher BMRs than women due to higher muscle mass.
- Body Size & Composition: Larger individuals and those with more muscle mass usually have higher BMRs.
- Genetics: Your genetic makeup can influence your BMR.
- Climate/Temperature: Living in cold environments can slightly increase BMR.
- Thyroid Hormones: Thyroid gland disorders can significantly affect BMR.
- Exercise: Regular exercise, especially strength training, can increase muscle mass and thus BMR.
