Well it seems like there is no way out of it. Just write of the month and start training when its over.
Can you consume anything at all? water?
I'm not giving my views on religion here, I believe religion can be a great thing I'm just telling you about my friend. He is a Muslim but does not fast at ramadan. He gives up on all 'nice foods' and drink. so he wont eat food for pleasure, like beer, and unhealthy snacks. He believes that his god understands and the traditon of fasting was created before we knew what was healthy for our bodies. He still eats to stay healthy and believes that is what his god would want him to do.
Again - I would like to stress that I'm not trying to offend anyone, I'm just putting it out there. I dont want this to turn in to a debate on religion.
