Well, if you are fat enough for the average american to notice you can expect a reduced lifespan. If you are slightly overweight relative to BMI charts you actually have a longer life expenctancy. (http://en.wikipedia.org/wiki/File:WikiRRM.jpg)
It's still relative but when you tip 40+ BMI you still have a significantly shorter life expectancy.
On average, obesity reduces life expectancy by six to seven years:[2][27] a BMI of 30–35 reduces life expectancy by two to four years,[21] while severe obesity (BMI > 40) reduces life expectancy by 10 years.[21](http://en.wikipedia.org/wiki/Obesity)
PS: I have a BMI of 34 so I want to know just how bad it can get if I let myself go any further. There is a lot of misinformation out there but being overweight has real negative effects on your heath.
