    The effects of glucose or lipid infused intravenously or intragastrically on voluntary oral food intake and diet selection in the rat
    (1995) Burggraf, Kimberly K.; Koopmans, Henry S.
    Glucose or lipid was infused intravenously (I.V.) or intragastrically (I.G.) for 30 minutes before and during the 17 hours when rats were fed. Three day infusions of 28. 1 kcals of nutrient yielded the following: ( 1) infusions of glucose reduced daily food intake by 19. 7 ± 1. 9 kcal/day, representing an oral intake reduction equivalent to 70% of each calorie infused, and (2) infusions of lipid reduced baseline food intake by 11.2 ± 2.7 kcal/day or 40% of each calorie infused (12.<.0005). In addition: (3) infusions of nutrient I. G. reduced baseline food intake by 17. 6 kcals ± 2 .1 kcal/day or 63% of each calorie infused, and (4) infusions of nutrient I. V. reduced baseline food intake by 13. 7 kcals ± 2. 6 kcal/day or 49% of each calorie infused (Q<.05). Infused glucose is more effective than infused lipid in inhibiting short term intake, daily food intake and intake of high carbohydrate diet, and I.G. infusion is more effective than I.V. infusion in inhibiting daily food intake.
