My understanding of a bear Belly is more of a swollen kind of thing.
Liposuction takes away fat, I don't think it would completely rid you of that beer belly, but i'm not a doctor! Cut down on the beer (as hard as that sounds!!!) and exercise a bit.
Here's one website i have found, if you type in beer belly on google LOADS come up. I realise that liposuction is an effort free way to lose it but this wedbsite says its only a 10 minutes a day workout thing. So thats not a HUGE undertaking!
