A new study finds men burn up to 101 calories during sex compared to just 69 calories for women. This is the first time science has been used to show difference in male and female calorie-burn during sex. And it seems the reason for the difference is that, in most cases, guys are doing a lot more of the "work", the Daily Star reported. The findings shatter the long-held urban myth that you use up 300 calories during sex and that there is no difference between men and women. It tallies with research by the sex toy firm Lovehoney, which found that 80 calories are used up during each intercourse session. Researchers worked with 21 straight couples who were asked to measure their calorie burn every time they had sex. They were asked to have sex in the privacy of their own homes on four separate occasions and to practise their usual sexual activities. To that end, they were instructed not to use Viagra or any other performance enhancement drugs and they were told to avoid any unusual sexual activities. During each sex session, the couples were told to wear an armband that could record the amount of energy expended. On average, participants' sexual activity sessions lasted around 25 minutes, although there was a substantial range that went from 10 minutes on the low end to 57 minutes on the high end. These numbers include time spent on foreplay as well as time spent on sexual intercourse. Across the four sessions, male participants burned an average of 101 calories each time (or 4.2 calories per minute), while female participants burned 69 calories (or 3.1 calories per minute). The research is published in the American scientific journal Plos One.Source: ANI << High Cholesterol Fuels Breast Cancer Growth California Health Insurance Exchange Focuses on December 23... >> Recommended Reading Three-in-one Combo - Getting Work Done, Charging the Laptop With Pedal Power and Burning Calories The innovative team at Pedal Power has focused on another product which can be used at the workstation that enables people to cycle and simultaneously charge a device like computer or a laptop.
