What's usually going on
From your late thirties muscle slowly gives way to fat, sleep gets shorter, stress gets quieter and appetite shifts. None of it is a character flaw, and none of it is fixed by being told to try harder.
Some men will do well with changes to food, movement and sleep. For others, treatment prescribed and monitored by a clinician is the right next step. The honest answer depends on you.
Wording under reviewClinician sign-off before publishing.
When we open, all of this happens online.
An honest assessment
A short online questionnaire, your height, weight and history, reviewed by a UK clinician.
A plan you agree together
Food, movement, sleep and, where it is suitable, prescribed treatment. Your clinician explains the options and what to expect.
Check-ins that notice change
Your weight, your energy and your Daily Debrief sit alongside your plan, so you and your clinician see the whole picture.
Three measurements. Four questions. Your numbers, explained.
Your BMI and waist-to-height ratio on screen with a plain band label, then a doctor-written report by email if you want it.
