> 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.

> According to the CDC, 9.4% of adults in the United States were severely obese between August 2021 and August 2023. This is higher for women (12.1%) than men (6.7%). The prevalence of severe obesity varies by age group, with the highest rates in adults aged 40–59 (12.0%)
Only 9.4% of people are severely obese. Moderately obese people have only a ~4% shorter life-span than healthy weight individuals - much of which can probably be attributed to other lifestyle issues besides simply being overweight.
This will move the needle, but I doubt as much as you think.
There's a lot more smokers than there are severely obese people.
