Frequently Asked Questions
What is RMR?
RMR (Resting Metabolic Rate) is the number of calories your body burns at rest to maintain basic bodily functions. It is measured under less strict conditions than BMR and is typically 5-10% higher.
How is RMR different from BMR?
BMR is measured after 8+ hours of sleep and 12+ hours without food in a thermally neutral environment. RMR is measured under more relaxed conditions (after a meal, not necessarily after sleep). In practice, the terms are often used interchangeably.
What factors affect RMR?
Body composition (muscle vs fat), age, gender, thyroid function, genetics, and body size all influence RMR. Muscle tissue is metabolically active, so individuals with more muscle have higher RMRs.
Can I increase my RMR?
Yes. Resistance training builds lean muscle mass, which increases RMR. Other strategies include eating enough protein, getting adequate sleep, and managing thyroid health.
How is RMR used in calorie planning?
RMR is a key component of TDEE calculation. Multiply your RMR by an activity factor to estimate your total daily calorie needs for weight maintenance, loss, or gain.
