Hi all, good luck with keeping your fast.
I'm just popping on to say that some Christians are fasting too because it is Lent.
The vast majority give up something they like for the 40 days but some denominations have stricter rules.
This is why (if you don't already know) 'Pancake day' is the day before lent and was used to use up all the flour / sugar /eggs.
Lots of Christians do something positively as well, extra prayer, charity etc. So if you give up Chocolate then you give the money saved to charity.
If you are doing a 'full on' fast it is 40 days but does not include Sundays so actually lasts nearer 6 weeks.
A full fast is only one meal in 24 hours, you can have 2 'snacks' but they must equal less than a meal and many adherents also give up meat and animal products so eggs, milk, cheese although fish is OK with most denominations.
A minority do not eat before Sundown.
If you already knew that, well sorry to bore you, if you didn't - well I find it fascinating that similar idears and practices exist.
Now I could also go on about Jewish and Hindu fasts but I'd have to check the dates.
I will add that for some Jewish fasts it isn't just food you don't eat (for 25 hours) but there can be restrictions on washing and wearing of leather.
