I don't know how long you intend to fast but do not worry about weight loss. I promise you will not waste away to nothing and become a skeleton if you are on a fast. Amazingly your body adapts and regulates. I just ended a 20 day fast and only lost 1 pound the last week. My main weight loss was the first 10 days. So ENJOY those pounds slipping away quickly because when you stablize you will realize that it takes alot more than a fast to lose weight. Don't let the family get you down. They cannot relate to your needs right now, so you need to be strong for yourself. You will never regret not caving into their demands. YOU deserve this fast. YOU are important too. YOU are giving them the best of yourself by fasting for health. I wish you happiness and a peace about what you are undertaking. Stay Strong.
