My voice is lower?

[Clodfobble]

I have no actual scientific basis for this, but it does seem to me that losing that much weight could do it. It's like, higher ranges require your larynx muscles to be squeezed tighter, right? And with the fat all crammed in there, it's like your larynx was wrapped in a tight donut, helping it stay squeezed. Now that the donut is gone, you've got room to open the muscles wider, but it also turns out your muscles aren't strong enough to maintain the high pressure on their own. In a capella groups, the deepest baritones are always skinny tall guys.
