Thank yourself!
Did you feel at any time that the calorie deficiency was eating at your muscles, instead of fat?
No. When I had to do something physical like snow shoveling, I wasn't dragged down at all. If there were some of that, it was subtle and unnoticeable.
Can't say what would happen over two months, but for the month I was drawing down fat.
Good to know; one of the assumptions I have is that calorie deficits attack muscle first. I must have read something wrong there, or remembered it wrong!
De nada ;)
I'm sure what you read is true if you're buff or don't have much fat on your bones.
