Ask Mary

By using the Activity Browser in the Exercise section, I found that an individual of your height and weight burns 72 calories per hour sitting quietly watching television.  That's the same number of calories you would burn by staring at a blank wall!  TV watching is positively associated with obesity (i.e. as TV time increases so does the obesity risk.)  Your goal should be to watch no more than 2 hours of TV a day, unless you want to exercise as you watch.  Read more about the effects of TV on weight at the Calorie Count Blogs.
