Intermittent very low-calorie diet lowers glucose levels in
Adults with obesity and type 2 diabetes improved glucose levels after eating a very low-calorie diet either 2 or 4 days per week, according to study findings published in the Journal of Diabetes Investigation.

Very few studies assess the effectiveness of different protocols of intermittent very-low calorie diet (VLCD) in patients with diabetes. This study was designed to compare the effects of 2 days/week and 4 days/week of intermittent VLCD on glycemic control, diabetes remission, metabolic parameters and quality of life in patients with type 2 diabetes and obesity.

Participants with obesity and type 2 diabetes were recruited and randomly assigned to three groups, consisting of control, 2 days/week and 4 days/week of intermittent VLCD. In the intermittent VLCD groups, participants received a 600-kcal diet per day on restricted days and ad libitum food consumption on non-restricted days. Glycemic control, rate of diabetes remission, metabolic parameters and quality of life were evaluated at baseline, weeks 2, 10 and 20.

Results:
-- A total of 40 participants were enrolled. The mean body mass index was 30.1 ± 5.9 kg/m2, and the mean glycated hemoglobin was 7.4 ± 1.2%.

-- At week 20, there was an improvement in glycemic control in both intermittent VLCD groups with significant decreases in glycated hemoglobin levels and insulin resistance index throughout the study periods.

-- Diabetes remission without the need for medications was equally found in 29% of participants in both intermittent VLCD groups.

-- Serum triglyceride, bodyweight, body mass index and fat mass were also significantly decreased in both VLCD groups. No serious adverse events were encountered.

Conclusively, intermittent VLCD was highly effective in achieving optimal glycemic control. The effects of 2 days/week and 4 days/week of intermittent VLCD on diabetes remission were relatively similar.
