Handgrip Strength
Handgrip strength measures how hard you can squeeze — a simple test of overall muscle strength that predicts health better than muscle size alone.
Plain English
Patient-Friendly Explanation
Handgrip strength is measured by squeezing a small device called a hand dynamometer as hard as you can, usually a few times with each hand. It sounds simple, but grip strength is one of the best quick indicators of overall muscle strength and health: it reflects how well your muscles and nerves work together and predicts future mobility, independence and even long-term health. In weight management, grip strength matters because losing weight too quickly can cost muscle, not just fat — and a falling grip reading can flag that. Preserving or building grip strength, mainly through resistance exercise and enough protein, protects your metabolism while you slim down.

Clinical Definition
Handgrip strength, measured with a calibrated hydraulic or electronic dynamometer in kilograms, is a validated surrogate for whole-body muscle strength and correlates with appendicular lean mass and physical function. Low grip strength is a core diagnostic criterion for sarcopenia in the EWGSOP2 consensus, with Asian Working Group for Sarcopenia (AWGS) cut-offs commonly cited around <28 kg for men and <18 kg for women; it independently predicts incident disability, frailty, falls and all-cause and cardiovascular mortality across populations. In obesity, grip strength discriminates between simple low muscle mass and sarcopenic obesity, where low strength coexists with high adiposity and carries compounded metabolic and functional risk. Longitudinal grip measurement during weight-loss programmes can detect unintended muscle loss early, guiding prescription of resistance training and adequate protein intake to preserve function.
Key Insight
Why It Matters
The bathroom scale cannot tell you whether you are losing fat or muscle — but grip strength can. We can measure it in a minute during your review, and tracking it across your weight-loss journey helps keep the weight you lose as fat, not strength.
