24 hour?
There are 12 days to Christmas, that's 288 hours of eating too much junk.
There are mince pies, Christmas pudding, stollen, creams, brandy butter, pretzels with peanut butter inside, various chocolates, savouries, nuts, obviously the turkey dinner(s) and there is bound to be stuff I have forgotten about.
I will deserve to be about 5kg heavier at the end and be about 1 or 2 as normal.
