Researchers at Huazhong University of Science and Technology found that people who became obese between the ages of 25 and 47 were at a 22% increased risk of premature death from any cause and a 49% increased risk of dying from heart disease.
The study also found that gaining weight between middle age and old age increased the risk of dying young, but that the same was also true for people who lost weight and went from obese to a healthy weight during this time.
