BF% level

[Munky]

If your bf% level is too low can that cause you to be cranky and tired alot of the time?

[David]

How low are we talking about here?

Give us a %.

What is low for you may or may not be low for us.

[Ritzol]

When your bf% is low, yes, some people experience fatigue.

I dunno about crankiness though, but that would make sense since some hormones are likely not functioning properly.

I am told that I have a tendency to be somewhat irritable when I'm hungry. I can't imagine why. *snicker*

Maybe that's your problem, rather than low BF.
