The detail, made simple

Why a measured metabolism changes everything

A generic calculator can be off by hundreds of calories a day. Over a month, that is the difference between progress and a plateau.

When we measure your RMR, your nutrition plan stops being guesswork and starts being math that works for you.

Before you come in

How to prepare for your RMR test

Your resting metabolic rate is sensitive to what you did in the hours before. These four things matter.

Fast for two hours

Nothing to eat in the two hours before. Water is fine, and skip caffeine that morning.

No exercise beforehand

Come rested. Training beforehand raises your metabolic rate and the reading will not reflect your true baseline.

Sit quietly on arrival

You will rest for a few minutes before we start. Build in ten extra minutes so you are not rushing in.

Leave the metal at home

No underwire, zips, buckles or heavy jewellery. Comfortable, plain clothing is ideal.
