I don't know what type of measurement and calculation was used (tape measure, calipers, , impedance, etc.), but accuracy may not be the same across all weight ranges. As mentioned, some of your lean weight is fluid and other tissues that goes down with weight loss. Even your total blood volume is higher with obesity. Also, when people gain weight, it's not all fat. It's partly muscle. When you're not carrying 300 pounds or 250 pounds around every day, you won't sustain the same muscle mass either. If you maintained all that lean body weight but got down to 18% bodyfat, you'd weigh 207 pounds, and that would be *extraordinarily* muscular for a 5'6" woman.
