BMR vs RMR

Your BMR (Basal Metabolic Rate) is measured in extremely controlled conditions — lying still, fully rested, and fasted. RMR (Resting Metabolic Rate) is slightly higher (~10%) because it accounts for the energy your body uses to digest food (the Thermic Effect of Food). RMR is the more practical number for everyday use.

What is the Thermic Effect of Food (TEF)?

Digesting, absorbing, and processing food burns calories — typically 10% of total calorie intake. Protein has the highest TEF (20-30%), meaning a 500-calorie protein meal might cost 100-150 calories to process. Fat has the lowest TEF (~3%).

How the RMR Calculator Works

The RMR Calculator draws on validated research in its domain to score or estimate your result from your self-reported or measured inputs. The methodology is grounded in peer-reviewed science, and results are contextualised against reference ranges used in clinical and research settings.

Wellness is multidimensional. This calculator captures one or more specific aspects of it. Use the result alongside your own self-awareness and, where relevant, professional guidance to build the most complete picture of your health.

Frequently Asked Questions

What does this score or result mean for my wellbeing?

The result reflects your current status across the dimensions measured by the calculator. It's a snapshot, not a fixed label. The goal is awareness — understanding where you are today so you can make informed decisions about lifestyle habits that support your mental and physical health.

How reliable are wellness scores?

Wellness calculators are based on validated psychological or physiological research, but self-reported measures introduce variability. Answer honestly and consistently across retests for the most useful trend data. Use results as a guide to reflection rather than a definitive assessment.

How can I improve my score?

Improvements depend on the specific dimensions involved. Common high-impact strategies include regular physical activity, consistent sleep schedules, mindfulness or stress-reduction practices, social connection, and addressing nutritional deficiencies. Small, consistent changes compound meaningfully over time.

How often should I retake this assessment?

Every 4–8 weeks is a useful interval for most wellness metrics — frequent enough to detect meaningful change, infrequent enough to reflect genuine shifts rather than day-to-day fluctuation. Some metrics (like mood-related scores) may benefit from weekly check-ins.

Can a calculator really measure wellness?

Calculators can quantify specific, measurable aspects of wellness — sleep quality, nutritional intake, physical activity — but full wellbeing is multidimensional and not entirely quantifiable. Use these tools as useful checkpoints alongside your own qualitative self-awareness.
