Exact length of time couples would need to have sex to burn off calories from Brits’ favourite meals revealed
LOVERS can burn off the calories from fish and chips by having sex — but it would take them nearly two hours, research found.
Couples burn an average of 162kcal between them for every ten minutes in the sack, boffins say.
A portion of cod and chips has 861kcal — so 1,722kcal for two — meaning it would take one hour and 46 minutes of lovemaking for both to use up the energy.
It could be even longer for those scoffing a Sunday roast, which can come in at more than 1,000kcal each.
Isaac Robertson, of fitness website Total Shape, said: “It’s important to note the number of calories burned during sex varies widely from one session to another.
“Different positions and how fast-paced it is can change the number burned.”
Half of Brits say they have sex once a week on average.
But it rarely lasts long enough to burn off a fatty dinner — with most saying anything over 30 minutes is “too long”.
Mr Robertson added: “If you’re looking to maximise the calorie burn during sex, then having a healthy diet and taking vitamins can help you last longer.”
