You have digestive cycle called the MMC Migrating Motor Complex which kicks into action 4 hours after a meal and takes, so if you have your last meal at 2:00 PM it will start at 18:00 PM. Beverages, fruit drink and sodas are all seen by the digestive system as food and will restart the time. Water doesn't delay the MMC so it is far better to drink just plain water. The MMC is a cleansing phase which includes rapid evacuation of the stomach, increased intestinal contractions and the preparation for a eating phase. If you follow the Hulda Clark e regime then the digestive phase will be completed and the MMC advanced when you take the first dose of ES. If you eat, take a beverage, soda or fruit juice it could potentially reduce the full effect of the protocol.
