Britons who find it hard to say no to food may welcome some handy tips on how to avoid weight gain this winter.
According to the British Nutrition Foundation, people gain an average of 2kg (5lbs) in the four-week Christmas period, meaning that a typical person consumes an extra 500 kcal a day.
However, experts insist that the festive period need not necessarily have to end in the usual new year diet, as there are several simple steps that can be taken to avoid piling on the pounds.
Bridget Aisbitt, a nutrition scientist at the British Nutrition Foundation, suggests that people should snack healthily before office parties so that they feel disinclined to eat the less healthy treats on offer.
She also recommends avoiding high-sugar alcoholic drinks, such as cocktails containing fruit juice and creamy liqueurs, as these will contain more calories than wine, for example.
The expert insisted: "You can still enjoy it. I think it's [a case of] picking your occasions.
"Weight gain doesn't really happen from one meal, it happens from consuming more than you need over a number of days and weeks."
Meanwhile, Ms Aisbitt's advice for those trying to lose weight ahead of the festive period of indulgence is to avoid making "huge sweeping changes" that you cannot maintain.
"There's no problem with going on a diet or something different for a little while, but it's important to realise that if you do that and then go back to how you were before, then the weight will just come straight on which is obviously really frustrating and depressing."
