The important bit missing from the Wiki link there is "irreversible". Alcoholic gynaecomastia doesn't go away when a bloke stops drinking; he can lose the pot belly, the love handles, but the moobs stay. Only surgery can get rid of them. :(
Women & booze is a bit less clear-cut. As a source of pointless calories, it will encourage fat to deposit wherever a woman's body tends to store it - this tends to be round the hips, but in the long term, alcoholic anorexia is pretty common amongst hardcore female drinkers. Economics plays a part...
