Using MTB to get back into shape, ?miles

I purchased a mtn. bike a week ago, a 2006 GT avalanche 2.0 disc. Not top end, but a decent bike for my needs. Ever since I was 15 I've strength trained and done some type of aerobic exercise, even did a bodybuilding contest at 18, I'm 37 now. Anyways, as life goes sometimes, I got out of my good habits and into some very bad ones (surfing the internet, sitting on my butt, drinking 6-8 beers 2-3 days per week). I was focusing on getting to the gym and doing what I've always done but with a wife and kids and a job I just don't have the 1 1/2 hours a day to spend in the gym that I used to have. I got frustrated at not being able to do what I've always done so the beer and internet was easier. I finally figured I had to find something to fill my exercise need. The mountain bike is working out GREAT! I've been riding anywhere from 3.7miles to 5.4 road miles daily. I'm familiar with the feeling of needing to recover so I listen to my body and take a day off when needed. I need to lose some weight but I'm a registered dietitian so that's not a problem. 5'7" approx. 225lbs now, goal 190lbs depending on bodyfat measurements once I get there. My motivation has returned so eating is not an issue, it's under control. Here's my question, should I continue just to cycle and increase the mileage as I feel I can or do I need a set "cycling program"? I don't have a problem pushing myself. I had a couple of harder rides earlier this week, my legs felt tired last night. Instead of riding hard, I rode my longest ride, almost 5 1/2 miles but it was all pretty much flat and I did it mostly to stretch my legs and take it easy. I felt good afterwards and my legs feel good this morning. Am I on the right track? Please give me any advice you feel is appropriate. I plan on continuing the road riding but also plan on doing some offroad mtn. biking trails around the area as able. But, I'm waiting to increase my fitness before I go offroad. Thanks in advance, Greg

Your riding distances look my first ones. I rode 5-15 km per ride during my first month on a bike and was proud of myself. Be the way the bike was GT MTB too, '97 arrowhead.
