Big voices

Does your weight affect your vocal chords or voice. I’ve noticed that alot of fat ppl have great voices like opera singers. If a fat person lost weight, would their voice change?

I have usually been fat.

For a while, I was not fat.

I have a “big” voice. I did when I was fit, and when I was fat.

I had much better wind when I was fit. I can’t yell as long now, although I can certainly yell as loud.
