Step outside for ten minutes right now. After that, you just equaled an hour workout. This comes from a study at the University of Sydney in Australia.They say that shivering 10-15 minutes burns as many calories as an hour of moderate exercise. Some sort of “brown fat” burns the calories. Daily Mail reports that the brown fat is the good fat because it can burn up to 300 calories per day, so much for white fat.
So if this is all true, why do we usually gain weight during Winter?
