(TheDrinksBusiness) - A new report claims there is no scientific evidence to support the assertion that beer causes weight gain and has labelled the beer belly a myth. Wine and beerThe report called “Beer & Calories; a scientific review” was written by nutritionist Dr Kathryn O’Sullivan and was sponsored by the beer industry. Dr O’Sullivan claims that because beer has fewer calories per 100ml than wine, spirits and orange juice, swapping certain beverages for beer could be a sensible way to diet. Although she does add that beer should still be drunk in moderation and if you consume large amounts of beer you will gain weight, but the same goes for those who consume significant quantities of wine.
