That is an odd, bold claim to make, that exercise doesn&#x27;t promote weight loss.<p>I&#x27;m at something of a loss to explain how, without changing my diet, but with adding 30-50 miles of cycling (plus a little jogging) a week, I&#x27;ve been losing around 5 pounds a month for the last six months.<p>Honest question time:  if it isn&#x27;t the exercise, what is it?
