"There has been interest in the effect of various types and amounts of dietary carbohydrates and proteins on blood glucose. Aim: to test the hypothesis that a diet that is low in carbohydrate, and particularly low in food-derived glucose, could lower FBG and the postprandial blood glucose in people with T2D."
5 weeks for each diet with a 5-wk washout between diets.
"Based on recommendations of the American Heart Association Standardized meals provided Targets E: individualized to maintain weight (2825kcal/d) Carb: 55%E, 388g/d; emphasis on starchy foods Protein: 15%E, 106g/d Fat: 30%E, 94g/d Sat fat: 10%E, 33g/d"
"Primary: blood glucose (HbA1c, FBG) Secondary: lipids, urinary and plasma BOHB, fasting insulin, glucagon, urea, creatinine to test compliance."
"All glycemic control measures SS improved on LoBAG diet, including Hba1c. Only lipid measure with SS change was for TG, favoring the LoBAG diet. Fasting insulin changes were NSS, while net and total 24-h integrated insulin area response were both SS lower on LoBAG diet. Plasma and urinary BHOB were similar on both diets."
"...a LoBAG diet can dramatically reduce the 24-h integrated glucose concentration and consequently the percentage of glycohemoglobin in people with T2D. These positive results occur without a signiﬁcant change in serum lipids, except for a signiﬁcant decrease in tRG concentration."
