I've definitely increased my fitness, but other than six pounds over many months, I wasn't able to lose any weight with cycling, probably due to the weight training I was doing, the fact that I'm a menopausal woman, and my riding had become training for a few long events, and other than interval training during the week, I was riding 60-80 mile rides on the weekend. I wasn't dropping anything, which my trainer told me would happen. Still, I felt great and looked like I weighed less than I really did. Since being injured six weeks ago, I've really been focusing on diet (only lots of fresh, non-starchy veggies, limited fruit, lean meats and fish in small portions), and I've lost 11 pounds. I'm sure some of that is muscle loss due to inactivity (doc said no exercise except stretching) which makes me sad because I was starting to look good (loving my legs), but I'm hoping to drop at least 10 more by the time I can get back on my bikes.
Keep it up, but lose the canned veggies if you can. Frozen are so much better. Cycling is just great for your health all around, and should inspire you to try out some other new habits. Maybe with the diet, just start with choosing one new healthy habit a week (e.g., no candy this week, or try frozen veggies instead of canned, etc.). Small doable goals are so much easier.
