Peristalsis, involuntary movements of the longitudinal and circular muscles, primarily in the digestive tract but occasionally in other hollow tubes of the body, that occur in progressive wavelike contractions. Peristaltic waves occur in the esophagus, stomach, and intestines.
As the ketogenic diet gains popularity, itâs important to have a balanced discussion regarding the merits of this diet. Let me emphasize right out of the gate that this is not a diet without merits (excuse the double negative); in fact, it has significant therapeutic potential for some clinical pathologies.
In What is a Low-Carb Diet?, I outline three approaches to low-carb eating, only one of which focuses on ketosis as a goal throughout the diet. Diets such as the Atkins Diet start out as a very low-carb ketogenic diet, but as people add carbohydrate, many or most will be eating too much carbohydrate to be in ketosis. It is probably more accurate to talk about the degree to which a diet is ketogenic rather than whether or not a diet is ketogenic.
