Hello waffleswaffleswaffleswaffles,
No.
and you will be extremely fortunate to find one.
Mainstream medicine make no distinction between fasting and starvation, as they believe that fasting and starvation are words that are synonymous and interchangeable, and where they also believe that there is no distinction between them.
If you would like me to elaborate on this distinction, then please let me know, as they are worlds apart.
According to Mainstream you will die if you abstain from food for longer than 5 days.
Absolute and complete nonsense.
