24-hour patterns of blood sugar, plasma insulin and free fatty acids in patients with primary endogenous hyperlipoproteinemia on isocaloric diets containing 30, 40 and 79 cal% carbohydrates.
10 patients with primary, endogenous hypertriglyceridemia (type IV hyperlipoproteinemia) underwent three different isocaloric dietary regimes of 10 days duration each. The diets contained either 30, 43 or 79% of calories as carbohydrate with 20% of calories from protein. Analyses of insulin, blood sugar and free fatty acids were conducted on the last day of each dietary period, at frequent intervals. There were no differences in either fasting or diurnal blood sugars with the different diets. Insulin levels were positively correlated with the amount of carbohydrate in the diet and there was an inverse correlation between the carbohydrate contents of the diets and circulating free fatty acid levels during waking hours. Since glucose tolerance is maintained, and diurnal plasma lipid levels are lowest with the low fat regime, such diets may be advantageously used for patients with endogenous hypertriglyceridemia.
