Lean body mass

Can someone explain what lean body mass is? How does it correlate with losing weight?

Thank you!

Lean body mass is your muscle.

Muscle is good, even for a girl.

You want muscle, but sadly muscle is very hard to earn.

When you are losing weight, what you really want to lose is body fat, losing muscle makes you sad.

Not sure if I did it right, but I am a month into my weightless/exercise plan. I took measurements and did an online calculator. I have lost 12 lbs..and it says I gained 9 lbs of lean body mass. Could this be correct?

LBM is not just muscle, it's your total body mass without fat - bones, muscles, organs etc. However, when your LBM changes, obviously that indicates a change in muscle since once you're a fully grow adult, adding bone or organ mass is impossible (unless there's some medical issue/anomoly involved).

OP, it's impossible that you gained 9 pounds of LBM in a month. I'm not sure those calculators that go by measurement are very accurate. I think the best way to know for sure is to have your body fat measured by a personal trainer with calipers or one of those fancy body fat calculating machines. As a woman, about the most you can gain a month is 1 pound of muscle and that's with a very strict regime of diet and exercise.
