those with normal weight, people who were overweight or obese had no
increased risk of death during a follow-up period of six years. People
who were severely obese did have a higher risk, but only if they also

higher short-term mortality with any amount of extra weight, The Journal

currently a widespread belief that any degree of overweight or obesity

associated with an increased risk of death, due to co-occurring diabetes
and hypertension," said a California statement.
