Almost 32% of obese adults who did not have multiple metabolic risk factors at baseline had developed them in 5 years time. The percentage rose to 40.9% in 10 years, and 51.5% after 20 years. This data was gathered from the long-running Whitehall II study in Britain. Only one in 10 of these people lost enough weight over 20 years to become healthy nonobese people.
