Very possible. The stock forks on entry level bikes can be super heavy. I took off a 130mm RST Launch and put on a 160mm RS Domain that I thought was going to be crazy heavy, and actually dropped weight.
I don't know if heavier is better for fitness/weight loss though, since you could just ride the lighter bike faster. I'd say it's a wash.
