Another +1 for avoiding foods your grandmother wouldn't recognize. When I eat energy bars, e.g., Lunas, I actually gain weight no matter what I'm doing or what my diet is like.

As for exercise, mixing it up is good, especially since you only have 1-2 hours during the week. Interval training is tough but has been shown to be an effective fat burner along with preserving muscle mass. I would add in a couple of interval days during the week. So - maybe a couple of days weight training, a couple of days of intervals & use your weekends for your LSD rides (Long Slow Duration.) Take one day off a week for physical/mental/spiritual health.
