In the KE diet, a feeding tube is inserted through the nose of an individual down their
oesophagus. At the other end of the tube is an electric pump. The only nourishment the patient receives is KE diet powder – an infusion of
proteins, fats and micronutrients with no
carbohydrates – mixed with water through the feeding tube. The patient only takes in about 800 calories a day, but the infusion is constant and the absence of carbohydrates curbs hunger. The dieter does not need hospitalization but requires doctor supervision and can carry the pump and liquid with them. The pump can be removed for up to one hour a day. While on the diet, the individual cannot eat anything and may only drink water, tea, coffee (with no milk, sugar or sweeteners) or sugar-free herb teas with the tube in.
Laxatives may be given to dieters to ease
constipation caused by the diet. Practitioners screen their patients before administering the diet to them and monitor them with blood and urine tests during the diet. == Safety and effectiveness ==
