You can't have alcohol during the Lose It! phase. After that, you can have a little bit of alcohol: about 75 calories a day, on average.
Where Does Peristalsis Occur. Peristalsis occurs throughout the digestive tract. It begins with the primary peristaltic wave in the esophagus as you swallow food from your mouth to the stomach. As food enters your stomach these muscular movements continue right through to your anus, where waste is eliminated from the body.
Upon entering the esophagus, peristalsis (wave-like contractions) of smooth muscle carries the bolus toward the stomach. Two layers of smooth muscle, the outer longitudinal (lengthwise) and inner circular, contract rhythmically to squeeze food through the esophagus. Throughout the digestive tract, smooth muscle peristalsis aids in transporting food. From the esophagus, the bolus passes through a sphincter (muscular ring) into the stomach. All sphincters located in the digestive tract help move the digested material in one direction. When the stomach is empty, the walls are folded into rugae (stomach folds), which allow the stomach to expand as more food fills it.
