Skipping a meal or two may not be the safest way to fit into a smaller size but it does have some benefits. When people choose to go days without food they may loose some weight however once they begin their normal routine that weight will probably show back up. Keeping a fast as a part of a monthly routine has a great benefit. There have been studies to show that a monthly routine fast can give the digestive system a rest allowing the body to clean itself out. Those fasting to lose weight can also consider the monthly fast as it will help people to go down a size or two when they are consistent in their fitness plan.
