For lent you mean? I am not a big fan of fasting and I don't believe that we have to submit our bodies to such torture without any reason. But if you are one of those people who believe in fasting then I would suggest that you take care over it. When you are fasting you must keep in mind that your body will constantly demand food and you cannot succumb to it. Do you think its worth it? Why not just be normal and eat food three times a day. It is so much more easier and life will be less complicated.
