Maybe you should focus less about the # and more about what it's made up of ? If you've gone from sedentary to very active, you have probably put on some muscle mass as well as fat loss. I'd get a tape measure (waist size) and a body fat scale to get a better picture of where you are.

Comparing before and after blood pressure, cholesterol levels and your every-day performance (like: stairs) will also give you a better picture on what matters the most.

My weight fluctuates crazily due to water retention or mild dehydration. It varies up to 8#. The bodyfat scale seems to help me figure it out.

Bike rides I seem to have more trouble losing weight than I had when swimming. I guess I'm afraid of going out on a ride then bonking or not being strong enough to manage the hills or running out of the time allotted (ie, get to work/finish before sunset). Afterwards my appetite is huge. When I swim, I'm never farther than 50 feet away from the end of the workout and I am usually just tired, not hungry, when I finish.
