The average runner could fuel 13 marathons on this snack alone

If there was ever another reason to sign up to that next marathon (and then pop down to the shop), this would be it.

New research has looked at the snacking habits of 1,940 people and found that the nations’ most popular guilty pleasure is chocolate biscuits. In fact, the odd biscuit here and there actually mounts up to an average of over 32,000 calories per year – enough to fuel at least 13 marathons.

According to research by myvouchercodes, the top ten guilty pleasures us Brits consume most in terms of calories are:

Chocolate biscuits – 32,256 calories per year
Fast food – 30,177
Crisps – 29,520
Chocolate bars – 28,800
Ice cream – 26,272
Cakes – 25,272
Cheese and biscuits – 16,450
Alcohol – 15,456
Pastries – 15,080
Puddings – 14,650

Anders Nilsson, spokesperson at myvouchercodes, said: “When all the calories from all the treats we eat in a year are added up, it can look pretty shocking – the average biscuit-loving person goes through the equivalent of 389 chocolate digestives a year. But these salty, sugary, fatty foods are treats, and a bit of what you like every so often is just fine.

I was surprised to see chocolate biscuits beating fast food and pastries, which might say something about my own eating habits, but in a famously tea-drinking country perhaps it’s inevitable that a good, dunk-able chocolate biscuit will be the nation’s top indulgence.”

Now, where did we leave those Hobnobs?
