Sex good for weight loss? Scientists say otherwise…

For the longest period it has been believed that sex and weight loss were closely related. Doesn’t seem so.

Scientists in New England Journal found that a man who is about 70kg would ‘expend approximately 3.5 kcal per minute (210 kcal per hour) during a stimulation and orgasm session’.

This is like taking a walk at about 4km/hr.

Then this:

Given that the average bout of sexual activity lasts about 6 minutes, a man in his early-to-mid-30s might expend approximately 21 kcal during sexual intercourse.

Of course, he would have spent roughly one third that amount of energy just watching television, so the incremental benefit of one bout of sexual activity with respect to energy expended is plausibly on the order of 14 kcal.

Facts suck.
