Understanding Your BMR Result
Your Basal Metabolic Rate (BMR) represents the number of calories your body needs to perform basic life-sustaining functions like breathing, circulation, and cell production — while at complete rest.
Knowing your BMR is essential for setting personalized calorie goals, whether you're trying to lose, gain, or maintain your weight. It's also the foundation for calculating your Total Daily Energy Expenditure (TDEE).
| Factor | Effect on BMR | Explanation |
|---|---|---|
| Gender | Men typically have a higher BMR | This is due to generally having more lean muscle mass, which burns more calories at rest. |
| Age | BMR decreases with age | Muscle mass tends to decline with age, slowing the metabolic rate. |
| Weight & Height | Higher values increase BMR | Larger bodies require more energy to maintain basic functions. |
| Body Composition | More muscle = higher BMR | Muscle tissue is more metabolically active than fat. |
Note: Your BMR is calculated using formulas like the Mifflin-St Jeor equation. While accurate for most people, these results are still estimates. For a complete health assessment, consult a licensed professional.
