You may be celebrating, but that doesn’t mean that that you should send your judgement on holiday. Alcohol can interfere with your blood sugar by slowing the release of glucose into the bloodstream; it also contains a lot of calories – 89 calories per glass of white wine or champagne, 55 calories in a shot of vodka and 170 calories in a pint of stout beer. What’s more, alcohol breaks down your inhibitions and judgement, which makes you that much less likely to resist the junk foods that you would otherwise be able to pass up.
