Will sex-ercise shed those extra pounds?

Dear Alice,

You know how you often see that, for example, a 30-minute jog burns such and such number of calories. Well, I was wondering if there are any figures for sex. Thanks.

Dear Curious,

Burn, baby burn — talk about a great workout! While you may experience some of the same physical effects during sex as you would during a vigorous workout (sweating, rapid heartbeat), you may not want to rely on sex as a main source of exercise.

It is estimated that the average 175-pound person burns 150 to 200 calories during 30 to 40 minutes of sex. Of course this will vary, depending on a person's weight, the type of sexual activities involved, and a person's overall fitness level. When compared with activities such as running, cycling, or rollerblading, however, sex does not burn as many calories. A research article on sex and the heart suggests that the maximum energy expenditure during sex occurs during orgasm but returns to normal within two to three minutes after. So, while you may burn more calories during orgasm, this higher rate of metabolism is not sustained after orgasm has ended.

Keep in mind that the number of calories burned during sex depends on a variety of factors, including duration, intensity, length of orgasm, type of sexual activity (i.e., oral, vaginal, anal), and position. Individual factors such as age, weight, and body composition also influence how many calories are burned during sex as with any other physical activity. It may be helpful to check out What exactly does moderate intensity mean? in the Go Ask Alice! fitness and nutrition archives for more information on energy expenditure and how it is calculated.

If you are interested in finding ways to burn calories and/or achieve a higher level of fitness, you may want to consider starting/maintaining a regular exercise program. If you are a student at Columbia, you can check out the offerings at the Dodge Fitness Center and/or join the  CU Move initiative.  CU Move encourages members of the Columbia community to engage in active lives that include regular physical activity. The program provides participants with motivation and incentives to be active throughout the year. You can also check out the Centers for Disease Control and Prevention for more information on physical activity and calorie-burning.

So, while sex-ercise may not be the primary option for shedding pounds, you can still enjoy sex for the other benefits it provides.
