"Lean Mass" presented as "Muscle Mass" in the HealthMate app

Withings App

I have a Body+ scale and I am very happy with it. However, there is one thing that is bugging me.

According to the "Muscle Mass" explanation in the HealthMate app, the "Muscle Mass" is calculated by substracting the fat and bone mass from your weight. (For me, this is 83.7%.)

But according to all kinds of sources on the web Muscle Mass is 33-40% on average for adult males and is calculated differently. I think the HealthMate app is displaying my Lean Body Mass (LBM) -- not my Muscle Mass as it currently says.

I am surprised this is somehow misrepresented in a Health app. Correcting it would be nice.

    Hello,

    Thank you for your feedback. Lean mass (defined by the weight of your body minus your body fat) is different from muscle mass. Withings calculates muscle mass (also known as lean soft tissue mass) by subtracting your body fat and bone mass to your total weight. Other indicators can be used for "muscle mass", such as skeletal muscle mass. Lean soft tissue mass and/or skeletal muscle mass are both used to represent muscle mass.

    I was wondering the same thing. Withings even gives different reference values for muscle mass, compared to those that you find on the internet. But they give no explanation of what these alternative values represent. See here for the alternative reference values for muscle mass: https://support.withings.com/hc/en-us/articles/218500778-Body-What-are-the-normal-ranges-for-body-composition-

    Did anyone get a answer to this? Everywhere else they say 30-40 is normal, Withing says 70-80% without any explanation?

    Just got my body+, and it appears this is still the case, is there any fix for this, or should I return it?
