A structured 12-week calorie-restricted dietary intervention starting with a 6-week Very Low-Calorie Diet (VLCD) phase (800-1200 kcal/day) followed by a 6-week maintenance phase significantly reduces body weight and improves postprandial glycemic response in Korean adults with early type 2 diabetes and obesity.
For Korean adults with early type 2 diabetes and obesity, a structured 12-week program starting with a 6-week very low-calorie diet (800-1200 kcal/day, with meals provided) followed by a 6-week self-managed maintenance phase can lead to significant weight loss (approx. 7-8%) and improved blood sugar control. The key is the structured, phased approach and meal provision to ensure adherence.
This structured dietary intervention demonstrated substantial weight reduction and improved glycemic response in adults with type 2 DM, highlighting its feasibility and effectiveness as a guided strategy for weight management.
Why this rating
