Sustainable diet Puns

John the Baptist of Biblical fame used to walk through the desert in his bare feet. This left his feet tough, which is understandable- the hot sand and rough terrain would leave anyone's feet tough. He was known to receive signs from God and occasionally perform mystical feats. He subsisted on a diet of locusts and honey. Without access to dental hygiene at the time, this left him with somewhat bad breath. It also left him frail, as the diet wasn't varied and would have required an immense intake of food to be remotely sustained.

I guess that you could say that he was a super-callused fragile mystic plagued with halitosis.
