Its probably worth pointing out that men tend to carry weight on the belly, it does not have to entail beer at all. More over men that carry it predominately on their belly are at much higher risk of a heart attack.
So if cutting out the beer is not possible (I don't think I could do it) then have a look also at your diet. Tonight I made a risotto with mushrooms, onion, mixed organic beans, carrot and fresh peas.
What did you eat?
I am not preaching as I am around a stone over weight and I have sod all will power. What I do know is a run around like a maniac at work (which unfortunately is where I get a fair proportion of my calories) and I walk the dog daily. All I can assume is, if I was sat on my arse at a computer all day I would be a house.
