In my clinical experience, 20 stone is a weight where patients often reach a turning point. It is a heavy weight for the human frame to carry, and I frequently see patients presenting with mechanical issues—knee and hip pain—as much as metabolic ones. When I am managing a patient at 20 stone, I look for small wins. Losing even 5% of your body weight (about 6.3 kg) can significantly lower your blood pressure and improve your insulin sensitivity. It’s about moving from a high-risk state back towards a manageable one, one step at a time.
