> I've always lost fat when I gained muscles without changing my diet that much. The fat-burning aspect of muscle growth has been fundamental for me. 45 minutes of weight-lifting has had a far greater effect on fat reduction than 90 minutes of cardio. I don't know that I can say it's "weight-lifting" vs. "cardio", but rather the specifics of what those entail. I do free weights, and feel like I work my body out better than the cardio work that I've done. But I'm with you in that respect -- building muscle is effective for fat loss for me, and I achieve that better through weight-lifting vs. cardio.
