From the dangers of “turkey back” to the secrets of Santa’s sexiness, universities across the land have served up weird and wonderful festive titbits this Christmas.

Food and drink are common themes in a number of universities’ festive news releases.

The University of Brighton provides information on how much walking, horse riding or mountain biking is needed to work off a Christmas bulge caused by scoffing a turkey dinner, mince pies, Christmas pudding, a few chocolates and some mulled wine. For example, a 2,000-calorie turkey dinner with all the trimmings would be dealt with by an 18-mile walk or a three-and-three-quarter-hour bike ride.

The University of the West of Scotland takes the opportunity to link Christmas bingeing to Scotland’s fight against obesity, while Leeds Metropolitan University, highlighting a weight-management initiative, says that youngsters can often consume nearly four times their recommended daily amount of calories on Christmas Day.

The seasonal fun does not end there. A video shows scientists at the University of Nottingham , on which the usual tinsel, baubles and chocolates have been replaced with plastic models of molecules.
