Maintaining Muscle Mass while Malnourished

I'm working on a character who is homeless and relies on stealing and cheating just to get by. Obviously, not having a steady/reliable source of food or income (in a small village nonetheless) means they're probably pretty malnourished (at least to the point where their ribs are somewhat visible). The problem comes with the fact that their weapon of choice is a bow and arrow, which I know requires a lot of upper-arm strength. My question is this: would it be possible for them to maintain enough muscle/strength to feasibly use a bow while malnourished? 

I tried several searches related to this topic, and read articles on WebMD and Mayo Clinic relating to malnutrition, but I couldn't find a single line anywhere specifically talking about whether or not one can maintain muscle mass while malnourished.

Also, the story is set in a fantasy world not our own, so there's not really a real-world time period with which to compare. Though- if this helps- there's not a lot of technology beyond simple things like watches, for example.

Is there a technical term for artificial light diffusion on snowy nights?

If you’re sighted and have experienced a heavy nighttime snowstorm in an illuminated urban area, you know what I’m talking about: the sandwich of light between the snowy white ground and snowy white sky, infusing the landscape with the soft white light of a frosted light bulb—-sometimes enough to read by, certainly enough to see by. (It must be coming from the ambient artificial lighting; my personal experience is that snowy nights on back country roads are darkness manifest.)

This is a subcategory of skyglow (https://en.wikipedia.org/wiki/Skyglow); I’ve come across “snowglow”, for light reflected from snow-covered ground (https://www.sciencemag.org/news/2019/08/light-reflected-fresh-snow-can-outshine-moon) but the article specifically discusses snowglow’s contribution to urban light pollution and interference with astronomical observation—-necessarily implying clear nights.

“Whiteout” overlaps with what I’m looking for, but specifically denotes reduced visibility; I get the impression that a whiteout need not be nocturnal or involve artificial light sources: http://www.awstats.net/whiteout/

“Diffuse reflection” seems to cover it somewhat: https://en.wikipedia.org/wiki/Diffuse_reflection

To repeat: what I have in mind is the reciprocal reflection/diffusion of light from sources within the space between the snowy sky and snowy ground.
