Resting Metabolic Rate
Estimate your Resting Metabolic Rate — the energy your body uses at rest.
Energy at rest
Resting Metabolic Rate is the energy your body uses at rest to keep its basic functions running — very close in concept to Basal Metabolic Rate, differing mainly in the exact conditions under which each is defined and measured. This estimates it from your details, giving a figure for your resting energy use.

RMR, BMR and what the number is for
The distinction between resting and basal metabolic rate is technical — basal is measured under stricter conditions of complete rest, while resting is a slightly more practical measure — and in everyday use the two are close and often used interchangeably. Either way, it represents the large share of daily energy your body uses simply to keep going, before activity is added. As with any such estimate, it is a population-based approximation that varies between individuals with muscle mass, genetics and health, so treat it as a baseline rather than an exact figure. This is general information, not medical or nutrition advice; individual energy needs vary, and decisions about diet or health are best made with a qualified professional.
Frequently asked questions
What is the difference between RMR and BMR?
They are very close — basal rate is measured under stricter conditions, resting rate is slightly more practical. In everyday use the two are often used interchangeably.
Is the estimate exact?
No — it is a population-based approximation that varies between individuals with muscle, genetics and health, so treat it as a baseline.
Is this medical advice?
No — it is general information. Individual needs vary, and diet or health decisions are best made with a qualified professional.
