The God Diet

I have to explain the God Diet. I have invented the God Diet because I have come to understand through close scientific consideration that some food is evil and that a little spiritual guidance is a good thing is you are a bit fat.
The empirical evidence for this is zero but I have a lot of faith. Faith is a functional prerequisite of the God Diet.
Working on the premise that all Gods have set their canons against greed, self abuse and crisps I see the God Diet as a intra-religious diet suitable for followers of all faiths. For instance Buddhists are encouraged to wonder around India hoping some nice passer by will fill their begging bowl as they search for enlightenment on their way to the Ganges. During Ramadan Muslims aren't allowed to eat all day and Jesus took off to the desert and was so hungry he saw the devil who could easily have tried tempting him with ice cream but was too stupid, and went for riches and power instead.
So.....God wouldn't want you to eat some food because:
A) You don't need it. You will be fine without it and feeling hungry is very virtuous.
B) It's a horrible processed piece of evil meat.
C) It's made of alcohol and will make you half witted, kill your liver, cost the NHS millions of pounds and make you fight someone or be boring.
D) It's not courgette soup or similar.
The essential thing to ask yourself is "Is this food evil, bad or toxic?" if the answer is "yes" or "probably" don't put it in your mouth. Obesity obliterated!
Follow these rules for three months and you will be very thin and happy.
Obviously I haven't tested my theory. I have been on the God Diet for one week and I have accidentally eaten alcohol and half a slice of bread and my Jigsaw trousers still don't fit me.
Nonetheless  I have faith.
