What this means for your health
Cardiometabolic risk rises sharply in this band, but is far from deterministic — fitness, diet quality, and sleep substantially modify outcomes.
Practical next steps
- Consult a GP for a full metabolic assessment (blood pressure, HbA1c, lipids).
- Set an initial target of 5–10% body-weight loss — clinically meaningful and achievable.
- Combine dietary change, daily movement, and sleep optimisation.
- Discuss whether structured programmes or medication are appropriate.
