Effects of Low-Carbohydrate/High-Monounsaturated Fatty Acid Liquid Diets on Diurnal Glucose Variability and Insulin Dose in Type 2 Diabetes Patients on Tube Feeding Who Require Insulin Therapy

Abstract Objective: A low-carbohydrate/high-monounsaturated fatty acid liquid diet (LC/HMD) was investigated for its role in long-term glycemic control in tube-fed type 2 diabetes patients who require insulin therapy. Patients and Methods: The study included 10 type 2 diabetes patients requiring insulin therapy who were being tube-fed with a high-carbohydrate liquid diet (HCD). With stable glucose control maintained, these patients were monitored for glucose levels for 4 consecutive days by using continuous glucose monitoring (CGM). The patients were continued on HCD during the first 2 days and were switched to an LC/HMD during the final 2 days. The patients were then continued on the LC/HMD, and seven of the 10 patients were monitored for glucose levels for 2 consecutive days by using CGM after 3 months of feeding with the LC/HMD. Insulin regimens used included basal-bolus insulin in five of these seven patients and intermediate-acting insulin in two patients. Results: Based on CGM data, the indices for ...
