Slimmer Doesn’t Always Mean Fitter

From the article: "Dr. Tarnopolsky said that he got his best VO2 max — 86 milliliters of oxygen per kilogram of body weight — when he weighed 156 pounds. “Like everyone else, I said, ‘Maybe if I drop some body fat, it will go higher,’ ” Dr. Tarnopolsky said. So he got his weight down to 152 pounds. But to his surprise, his VO2 max decreased, to 82."
