>What’s the long term prognosis if the muscle tissue happens to be your heart?
The body rebuilds the muscle tissue from protein every day and your body has a lot of muscle mass.
Glycogen reserves are only about 1,500 to 2,000 calories. Which means if you ever do any sort of heavy physical activity for a prolonged period then you’re body will also use glyconeogenesis to produce Glycogen. It’s not starvation mode, it’s normal mode.

From what protein, if someone is on a water fast?
