Your right about the metabolism.
The bodies metabolism slows down. Thats the rate at which it burns fuel.
We all know what happens when you burn fuel. -- you get heat.
So less burning equals less heat.
Which makes summertime a wonderful time to do a MC. You rarely get hot when everybody's sweltering.
I have to correct you on the "starvation mode".
The body shouldn't go into starvation mode during a MC.
Only a cleansing mode.
When the body goes into starvation mode, the body is starving.
When it is starving it burns up muscle tissue.
Ever see old pictures of people that have been in prisoner of war camps.
They're mostly skin and bones, no muscle.
You got it, they were starving. Some for a long time.
The nutrition of the Master-Cleanse is designed to give at least minimum nutrition to the body, while at the same time allowing major bodily functions to slow or stop, which puts it into cleansing mode.
