There was once a girl who valued health, and on this basis she became vegetarian. Actually she became Vegan. Soon after, that girl decided to further restrict her diet to raw food only. She felt that raw food would help her further pursue her goal of health. Unsatisfied, she decided that despite these restrictions her body was still full of toxins and impurities – so she decided to fast for a week. She had the choice between a fast with no food whatsoever, or a soft fast which would have incorporated juices and some greens – you know which one she picked. After fasting for a week, she felt not yet purified and decided to continue for another three days. After ten days of drinking nothing but tea, she decided that the tea she had ingested was in fact a toxin and further purging was required to rid her body of its toxins. She decided that since she had been fasting for so long already, that she should first resume eating for the sake of fasting again, this time without any toxins whatsoever. However, although she forced herself to eat in order to further detoxify in the future, she found the process frustrating – she had begun to see food only as a collection of toxins. So, as she repeated the process – eat to gain strength for the sake of further fasting, each time she ate less and fasted for longer. While mentally she still understood that her body required food to further detoxify, she developed a bodily dislike of food – her body would no longer accept even the most health giving of foods without a fight. Finally, she was no longer able to eat anything. She was no longer able to fast, only to try to eat, which made her sick. Her body began to produce toxins to expel any food that she dared put inside. Her body began to rot. Her will to eat slowly passed, it was easier, she said, not to eat.
And thus she passed away – on her gravestone it is written, “SO here lies M , because it was easier, she said, not to eat.”
Only a Northern Song 
I think diets including meat, vegetarian diets, and vegan diets can all be perfectly healthy, though the last may require the most effort to do so. Being vegan is probably the most ethically acceptable, but vegetarianism is a decent compromise between health, convenience, and good morals.
I see no sense in raw foods, nor fasting for health reasons.
If this post is meant to be a ‘slippery slope’ argument, it isn’t very convincing. For one thing, the body gets pretty unhappy about not being fed pretty fast. After a one day fast motivated by moral rather than health concerns, I could attest to that.
I actually find that after the initial nagging hunger ceases, eating becomes totally unappealing.
For me, when I get into a bad eating cycle, eating becomes nothing but a chore. I don’t feel hungry, I just get dizzy when it becomes dangerous. I can usually justify my reasoning by telling myself that it I’m doing the morally right thing by buying less into the harmful food production system.
I think there’s something to be said here for the addictive nature of sacrifice.
This piece reminds me of my ‘rice and green tea’ diet that I embarked upon as a vegetarian (turned, I guess, vegan). It was actually an attempt at ‘eating clean’ as well.
(It ended in very poor health, but.. I did get to eat anything I wanted in large quantities for months afterwards, once I got my appetite back!)
This isn’t meant to be an argument. It’s a true story.
