You are in the lowest 9% for avg fat mass
Fat mass index
Fat mass adjusted for height; lower numbers generally align with better metabolic health

Osteoporosis is a silent killer
Your age, family history, and lifestyle push your risk up. The NHS is too slow and too reactive to catch it early. Neglected bone health can change your life
Osteoporosis affects 3.5M Britons
Most of them don’t know it until a bone suddenly breaks. There are no symptoms: you can’t feel your bones thinning over the years
Fractures can be lethal
Half of women and a fifth of men over 50 will break a bone because of osteoporosis. A hip fracture is a heart-attack-level event: roughly one in four over-50s die within a year
NHS waits have spiralled
The number waiting beyond the six-week target rose nine-fold in two years. Nearly half of services now miss it, and a quarter take over 13 weeks
