“…However, a large part of the postprandial glucose and insulin responses was explained by the amount of carbohydrates in the meal [43]. In another study, differences in fat amount did not appear to affect postprandial glucose or insulin levels [33]; therefore, fat amounts can be readily altered without any negative outcome. In fact, dietary fat is reputed to enhance the palatability of diets made for cats, and this may be the sole reason for including it as a constituent [19].…”

Impact of Commercially Available Diabetic Prescription Diets on Short-Term Postprandial Serum Glucose, Insulin, Triglyceride and Free Fatty Acid Concentrations of Obese Cats

ABSTRACT. Diet therapy is an important treatment component available for obese cats. In this study, the impact of four commercially available prescription diet regimens (1 for general use and 3 aimed at treating obesity and diabetes mellitus (DM)) on short-term postprandial serum glucose, insulin, triglyceride and nonesterified fatty acid (NEFA) concentrations was investigated with five obese cats. The diet regimens used were as follows: C/D dry (general use: moderate protein, moderate fat, high carbohydrate and low fiber), M/D dry (DM: high protein, high fat, low carbohydrate and high fiber), W/D dry (DM: high protein, low fat, high carbohydrate and high fiber) and Diabetic dry (DM: high protein, low fat, low carbohydrate and high fiber). A significant reduction (10-13%) in postprandial glucose (area under the curve; AUC) was observed with the M/D and Diabetic diets, which both contained lower concentrations of carbohydrates than the C/D diet. An accompanying significant reduction (30-36%) in postprandial insulin AUC was also observed with the three DM diets, which all had higher amounts of fiber, as compared with the C/D diet. Lastly, a significant increase (32-65%) in postprandial NEFA AUC was observed with the M/D and Diabetic diets as compared with the C/D diet. Therefore, dietary amounts of carbohydrates and fiber, as opposed to protein content or dietary fat, appear to have a very significant impact on postprandial glycemia and subsequent insulin requirement levels in obese cats. In addition, dietary amounts of carbohydrates may also impact lipid metabolism in obese cats.

“…It is possible that the fat and carbohydrate contents of an evening meal affect GI determination the following morning. Peak blood glucose concentrations to an oral glucose challenge were higher when the previous evening meal contained high fat compared with high carbohydrate (Robertson et al, 2002). On the other hand, controlling the evening meal and activities compared with a less strict regimen resulted in postprandial glucose excursions after standardized breakfasts that were not different (Campbell et al, 2003).…”

The effect of the fat and carbohydrate contents in the evening meal preceding GI testing on GI

et al. 2009

A crossover study was designed to determine whether the fat and carbohydrate contents of evening meals consumed the night preceding glycaemic index (GI) testing had an effect on the GI. Twenty participants consumed two different evening meals in which the energy contributions from fat, carbohydrate and protein were in the ratio 50:30:15 and 25:60:15, respectively. Each participant completed eight tests that involved two evening meals with different macronutrient compositions followed the next morning by two treatments, glucose beverage or fruit bread, all carried out in duplicate. The GI of fruit bread was determined on the mornings following each of the evening meals. The GIs (95% CI) were 68 (60, 76) and 59 (52, 67) after the highcarbohydrate and high-fat meals, respectively, and were not different (P ¼ 0.11). Thus, varying the fat and carbohydrate contents of the evening meal before GI testing the next morning did not affect the GI.

Extended effects of evening meal carbohydrate-to-fat ratio on fasting and postprandial substrate metabolism

Abstract: The present study showed that the effects of high-fat and high-carbohydrate evening meals persist at least overnight and suggests that knowledge of recent dietary history is essential to the effective design of metabolic studies.
