Last time I went on a weight loss binge, I essentially ate only chicken and ground beef for about 2 months straight while weightlifting every morning. I went from 230lbs to 180lbs with little to no strength loss oddly enough. I dont recommend it though, by some miracle I've been able to keep the weight off for 4 years since I did it, but statistically most people wont when they do what I did. One big thing that has helped is that I've stayed with the daily weight training, I also mountain bike and ride my KX pretty frequently, and when I do, I typically try to ride pretty hard.
