ELI5: Do obese people, on average, take more from the tax pot (extra healthcare etc) or add more (because they die earlier and don't collect as much pension or old age healthcare) relative to the average person?

EDIT: see lung_doc's reply below which is much more betterer than this one.

Research has unfortunately shown that healthy people do cost more to society than unhealthy people. Despite the expensive medical procedures associated with common cancers and heart disease caused by bad diet / smoking, a healthy person who lives a long full life will inevitably face these issues in old age and for is likely to need more treatment over a longer period of time. Also, longevity is an inevitable drainer on the pension pot.
