Time-Restricted Eating May Aid Weight Loss With Type 2 Diabetes

THURSDAY, July 27, 2023 (HealthDay News) -- Time-restricted eating (TRE) may help people with type 2 diabetes lose weight, according to a study presented during NUTRITION 2023, the annual meeting of the American Society for Nutrition, held from July 22 to 25 in Boston.

Vasiliki Pavlou, R.D., from the University of Illinois Chicago, and colleagues compared the effect of eight-hour TRE, calorie restriction (25 percent), and no intervention (control) on body weight, cardiometabolic risk factors, and glycemic control in 57 randomly assigned adults with type 2 diabetes and overweight or obesity.

The researchers found that by month 6, body weight decreased significantly in the TRE group (−4.7 percent) versus calorie restriction (−1.6 percent) and control (−0.8 percent). There was also a significant decrease in fat mass in the TRE group versus control, but not versus calorie restriction. In the TRE group, high-density lipoprotein cholesterol increased significantly versus calorie restriction, but not compared with control. There were no significant between-group differences noted for changes in systolic and diastolic blood pressure, visceral fat mass, lean mass, low-density lipoprotein cholesterol, triglycerides, fasting glucose, fasting insulin, hemoglobin A1C, or insulin resistance at month 6. Throughout the trial, adherence to TRE remained high, with participants adhering to the eight-hour eating window on six days/week.

"There are multiple types of medications for those with type 2 diabetes, some of which can cause low blood sugar and some that need to be taken with food," Pavlou said in a statement. "Therefore, it is important to work closely with a dietitian or doctor when implementing this dieting approach."
