Hi Chrisb1, I ate vegetarian/vegan for 14 years. Some time ago I was reading an article on Mercola's website, written by Chet Day, which gave the following information on Upton Sinclair. (I did not realize he was a faster.)
"A famous writer and ex-vegan by the name of Upton Sinclair, the activist who forced the meat-packing industry to clean up its act many decades ago when he wrote The Jungle, found he couldn't maintain his work levels on a vegan diet.
Writing sadly that he hated to give up veganism, Sinclair did so nonetheless because he found his brain just wouldn't function at an optimal level on fruits, vegetables, juice, nuts, and seeds. He turned to Salisbury steak as his answer.
Although Upton Sinclair was nearly crucified by his vegan friends for changing his diet and writing about the positive results from the change, he maintained that he went where the truth led him."
I feel the same way.
I will be starting a Water Fast September 29. I will look forward to reading your posts!
