It would be pretty difficult to find the body variables without opening the game's files in a rpg maker mv project, you'd have to compare saves before and after a moment where you know a body variable was changed and then exhaust all the changed variables until you find the correct one, and it would then take some experimentation to find the functional range of the variables.
Here's a cheatsheet with the variable numbers and functional ranges tho.
Variables:
62 - Butt size [0,2] (higher is bigger)
63 - Breast size [0,4] (higher is bigger)
64 - Hair length [0,2] (higher is longer)
68 - Height [-1,0] (higher is taller)
75 - Skinniness [-1,0] (higher is chubbier)
122 - Nipples [0,3] (0 is normal, 1 is pink, 2 and 3 are black)
124 - Dick Size [-4,1] (higher is bigger)
126 - Face change [0,1] (0 is default, 1 is feminized)
128 - Skin tone [0,1] (not sure about this one)
129 - Shoulder size [0,1] (higher is slimmer)
286 - Hair color [0,1] (0 is default, 1 is blond)
I think those are all the transformations that are tracked through variables and have an impact on the MC's art and dialogue when looking at themselves in the mirror. There are some other TFs that are tracked through variables but aren't mentioned very often in the game or visually noticeable and other TFs that are controlled through switches. You can read about some of those

Admittedly the effective range is low enough that editing is probably unnecessary at this point if you're actually playing the game anyway, but if the variables remain the same into future updates this info can be very useful if you're a cheating POS like me that wants to custom sculpt your end result.
