Computer typing

Sometimes it feels like the whole day is spent at the computer—work, studying, social media, chatting. You might think this burns no calories, but your body disagrees. What you consider a “useless” activity for weight loss is actually real exertion for your body. Typing reports, handling business emails, or chatting with friends burns about 140 calories per hour. Add the energy your body expends just by sitting—around 60 calories per hour—and there’s even more reason to be happy.
