in Health and Weight Loss
I don't understand that the three months I was off MFP I ate what I wanted, didn't excersise and I managed to keep off the ten pound I lost. NOW, I am excersising, eating better (not perfectly, but better) and I have gained four pounds back. What is up with that? The only excersise I have been doing is cardio so it's not like I've been lifting weights to gain that much muscle. Please help! I need encouragement. :sad:

    You could still gain muscle from cardio. I know that the elliptical and treadmill (especially at an incline) uses a decent amount of muscle.

    Have you taken measurements along your journey?

    I have taken measurments, but am only losing a couple of inches throughout my whole body.

    Inches lost are inches lost. Here's an article at website: http://answers.google.com/answers/threadview?id=576481

    Subject: Re: Muscle Density vs. Fat Density
    Answered By: raisingmyhand-ga on 17 Oct 2005 16:30 PDT

    Hello Holstein13,

    Thanks for your question. I hope you will find this answer to be
    provided with solid scientific references.

    Summary: Muscle density is 1.06 g/ml and fat density is (about) 0.9
    g/ml. Thus, one liter of muscle would weight 1.06 kg and one liter of
    fat would weight 0.9 kg. In other words, muscle is about 18% denses
    than fat. This should not be confused with the "energy density" of
    muscle and fat, which may be where you got the 3x figure that you
    mention in your question.

    I have made a special effort to find credible sources for the answer.
    Below I provide sources for the two numbers separately.

    1. The density of mammalian skeletal muscle is 1.06 g/ml.
    "... 1.06 g/cm-3 which is the density of mammalian skeletal muscle"

    composition of mammalian muscle. Metabolism 9:184-188.

    2. The density of adipose tissue (fat) is about 0.9 g/ml
    "...by multiplying the density of adipose tissue (0.9196 g/ml)"

    I hope you find this to be useful and a complete answer to your
    question. Let me know if there is anything I can clarify.

    Regards,
    RMH

    Search Strategy:
    I searched Google using the phrase "density of mammalian skeletal
    muscle" and "density of adipose tissue". I used a computer in a
    medical center that has free, online access to many scientific
    journals.

    Also another place that can help you determine if it's fat or muscle.

    Thanks. I looked at the last website you gave me. It makes it simple to determine. I just need to get a thing to measure my bodyfat.
