You're Doing It Wrong

A CBC article entitled "7 Obesity Myths Shattered" takes a turn for the hilarious as it tackles myth number seven: "A bout of sexual activity burns 100 to 300 calories for each person involved." One Stefanie Senior, a Toronto dietician, disagrees: "'At the end of the day, it only burns less than 50 calories,' she told CBC News."

There certainly is a large gap between 50 and 300 calories, isn't there? Using the exercise lookup tool over at MyFitnessPal.com reveals the following (the default value of 150 pounds of body weight was used for all results):

• 30 minutes of cooking burns 68 calories
• 30 minutes of playing lawn darts burns 85 calories
• 30 minutes of walking at a slow pace burns 85 calories
• Sitting and playing the guitar for 30 minutes burns 68 calories
• 30 minutes of mild stretching burns 85 calories

Poor Stefanie Senior!
