And mega miles + eating everything in sight = weight gain. The (obvious) point was that all else being equal, a modest exercise program is better than nothing and, more on point, better than an ambitious exercise program that can't be sustained and ends up being nothing (see: http://www.nytimes.com/2010/06/29/he...?ref=nutrition). No one should expect to lose 10 lbs a month on such a program, but over a period of years it will assist in weight management. Don't get me wrong, I'm not trying to justify my own level of riding (over 800 miles for July). But I don't think people who do much less should be dismissed as wasting their time. On the other hand, as pointed out in the previous posts which I agreed with, they should also be realistic about the benefit they will receive.
