you are carb depleted and when you are carbed up.

currently on a carb depletion cycle. and got bf% tested, and i know when you are carbed up, your muscles get "bigger" or fill out more, and your skin tightens around the muscle.

Does anyone know this?

currently at around 13% bf at carb depleted

hopefully some bb'ers who are cutting for comps can help me with this

If you don't add bodyfat with a simple carb load then take all the additional weight gain you get and apply that to your skin fold measurements.

So if someone goes from 200 to 205 on a carb load then basically they just added 2.5% more LBM mass. (LBM mass is a funny measure and so is BF%. Basically if it's not fat it's LBM). If you were at 10% BF (20lbs of fat) now you should be at about 9.75% BF.

Something like:

Absolute difference = |205 - 200| = 5
Average value = (205 + 200) / 2 = 202.5
Percent difference = (5 / 202.5) X 100 = 2.47%

10/1.0247 = 9.76%BF (Assuming you didn't add any fat)

The real question is ... Who cares?
