Time-Restricted Eating Shows Modest Weight Loss in Adults with Obesity and Prediabetes

A study suggests time-restricted eating (8-10 hour window) can lead to modest weight loss in adults with obesity and prediabetes or diet-controlled Type 2 diabetes.

The 12-week study investigated if restricting meal timing without calorie restriction impacts weight, eating behavior, inflammation, and appetite hormones.

39 adults (92% female, 92% Black, ages 18–69) with obesity and prediabetes/Type 2 diabetes were assigned to a 10-hour eating window or a 16-hour usual pattern.

Both groups followed a personalized DASH diet with their usual caloric intake maintained. Meals were prepared by researchers.

At study's end, both groups showed similar, modest weight loss: 2.7% for the time-restricted group and 2.5% for the usual pattern group.

Both groups reported improved eating behaviors, including greater restraint and reduced hunger. Appetite hormones and inflammation markers were comparable.

The study found that while time-restricted eating led to weight loss and improved eating habits without calorie restriction, no unique health benefits beyond weight loss were identified.

Future research will explore time-restricted eating's role in weight loss maintenance. Authors disclosed potential conflicts of interest.
