It’s true that good sex burns up calories; but the choice of a position is also very important. German scientists conducted an experiment involving about 500 couples. Volunteers were requested to have sex in the vertical position only, standing and not less than once a day for two weeks.
The result showed that during the 14-day period the female participants dropped from 3 to 5 kilograms without cutting down on their meals or sweating in the gym.
The reason is that when in the standing position people use up the greatest amount of calories. Partners have to move more and spend more energy on body movements than, for example, when in the missionary position, in which the woman is quite passive.
