Abstract
The effects of refeeding on REE and body composition were studied in 6 malnourished patients with cystic fibrosis, before and following 6 months treatment. REE was measured by open circuit indirect calorimetry after an overnight fast (12-14h) and results expressed as % of predicted (Harris-Benedict). Body composition waa determined by anthropometry and total body potassium.
Refeeding increased body fat, lean body mass (LBM) and resting energy expenditure (REE). We have previously shown that the REE of CF patients increase as their pulmonary functions worsen. We concluded: (a) that our CF patients initial REE was (relatively) reduced due to undernutrition; (b) that refeeding increases the caloric needs of CF patients.
