turned 40 last month and just got hooked cycling :)

It seems to me that most people don't lose much weight from cycling, because it makes you so hungry. So, you can ride as much as you want, but back off if anything starts to hurt, and eat more if you get too thin or weak. To me, the "ideal" is the place where I feel great, where nothing hurts, and it's fun to get on bike. Usually, if I ride too much, I feel fatigued, and if I ride too little, I get moody.

In my case, I'm the opposite. I'm doing Jenny Craig to loose some residual x-mas gained pounds but also started cycling as well and IM ADDICTED!!! So since I still want to loose 5 to 8 pounds before summer, the days that I ride my bike I have to eat at least 300 additional calories to avoid hitting a plateau. I'm 5'8 -153 pounds (not for long!)

Bike enough that it feels good and you're not burning yourself out. Add other things in there--some kind of weight-bearing cardio, weights (still trying to work that one out), some kind of core work, yoga--whatever sounds appealing to mix it up. That way your muscles get a different kind of work out, and you don't get burned out on one thing.
