I've always gained 5+lbs in winter, so this year I decided to up my winter riding and see what happens. Well, I still gained 5lbs (at least it wasn't close to 10 like last year). I rode slightly less than I do in the warmer months, but this January I got a trainer because we had snow/ice for the entire month, so I didn't ride THAT much less. I watched what I ate, consumed less calories than I do in summer, and still gained 5lbs.

Now, it's DST, and I've started commuting to work, and the lbs are dropping, just like always at this time of the year. I'm wondering if it's not the amount of miles I'm riding that keeps my weight in check, but the 2 rides per day. I'm actually doing slightly less miles due to a hectic schedule right now.

Could it be that I'm boosting my metabolism by the second ride/day, even though it's not as much time in the saddle?

I should add, even at my winter weight, I'm within normal weight range. I just can't wear a certain pair of jeans and breathe!
