Effect of a low-carbohydrate diet on appetite, blood glucose levels, and insulin resistance in obese patients with type 2 diabetes.
Effect of a low-carbohydrate diet on appetite, blood glucose levels, and insulin resistance in obese patients with type 2 diabetes. G Boden, K Sargrad, C Homko et al. Annals of Internal Medicine, March 15, 2005, 142:6, pages 403-411.
"Primary: weight, body, water E intake and expenditure, HbA1c, insulin sensitivity, FBG, insulin Secondary: and composition, diet satisfaction, BPHB, leptin, and ghrelin (hourly measures) "
Weight loss was due to deficit in E intake. 24-hr glucose profile normalized; HbA1c, insulin sensitivity, TG and total cholesterol levels improved.
"WG: NR BG: Y Glucose infusion to maintain euglycemia increased 30%"
Dosages for several medications decreased in several patients.
"Blood urea N SS increased 5.85→7.14mg/dL Serum and urinary creatinine, uric acid, urinary albumin excretion: NSS change "
"Diet satisfaction: questionnaire responses indicated low-carb and usual diet about equal in terms of hunger, E level, satisfaction, comfort. Renal function: blood urea nitrogen: SS increase. Serum and urinary creatinine, serum uric acid, urinary albumin: all NSS. Leptin: SS lower at end of low-carb diet. Ghrelin marginally lower."
"In a small group of obese patients with T2D, a low-carbohydrate diet followed for two weeks resulted in spontaneous reduction in E intake to a level appropriate to their height; weight loss was completely accounted for by reduced caloric intake; much improved 24hr blood glucose profiles, insulin sensitivity, and HbA1c, and decreased TG and C levels. The long-term effects of this diet, however, remain uncertain."
