What is the life expectancy of an obese person?

The Oxford University research found that moderate obesity, which is now common, reduces life expectancy by about 3 years, and that severe obesity, which is still uncommon, can shorten a person's life by 10 years. This 10 year loss is equal to the effects of lifelong smoking.

Does obesity shorten your lifespan?

Obesity is associated with a reduced life expectancy, largely because obese individuals are at increased risk of so many medical complications. But not all obese individuals are the same, and some do not have the metabolic abnormalities that often accompany obesity.

What is the life expectancy of a 300 pound man?

At 250 pounds (113 kilograms), his life expectancy falls by three years, and at 300 pounds (135 kilograms) by seven years. At 332 pounds (150 kilograms/BMI of 45), his life expectancy plummets by 13 years.

What is the average lifespan of an obese woman?

For women, the total years lived as well as those lived both active and disabled were longer than for men. At age 70, nonobese women could expect to live 15.3 years; obese women could expect to live 15.5 years. Similar to men, nonobese women lived more active years and fewer disabled years than obese women.

Why do obese people have shorter life expectancy?

More rapid aging: Obesity may be slowing life expectancy gains by accelerating biological aging, particularly among U.S. women. Biological aging occurs more than two years faster among nonsmoking individuals with obesity, contributing to earlier onset of chronic disease, disability and death.

They found that women have a 25-percent increased likelihood of living past their ninth decade without serious disabilities or chronic illnesses (such as heart disease, cancer, or diabetes) if their mothers did. If both mom and dad maintain their health to age 90, daughters are 38 percent more likely to do the same.

What is the difference between morbidly obese and obese?

What BMI has longest life expectancy?

Participants whose BMIs were between 40 and 49.9 were more than twice as likely to die during the study period than those whose BMI was in the optimal range of 22.5 to 24.9.

What are the stages of obesity?

Overweight (not obese), if BMI is 25.0 to 29.9. Class 1 (low-risk) obesity, if BMI is 30.0 to 34.9. Class 2 (moderate-risk) obesity, if BMI is 35.0 to 39.9. Class 3 (high-risk) obesity, if BMI is equal to or greater than 40.0.
