Ketogenic Enteral Nutrition – KEN™ Weight Reduction System.
This novel technique to assist overweight patients with Body Mass Index (BMI) over 25 involves the placement of a fine-bore Nasogastric Tube (2 mm diameter) to allow the continuous infusion of a specially formulated feed over a 10 day period via a portable pump. Patients are able to carry out their normal duties over this period and are encouraged to drink generous amounts of fluids, but do not feed for this period. KEN cycles can be repeated after a 10 day break interval, until the patients reach their target. This target is calculated from Bio-impedance measurements at each visit to the clinic.
