Whether wearable technologies that monitor physical activity and diet improve long-term weight loss is not clear. In a clinical trial involving 471 overweight and obese young adults, Jakicic and colleagues compared weight loss among participants randomly assigned to use a wearable technology and to participate in a standard lifestyle intervention of low-calorie diet, prescribed increases in physical activity, and group counseling with weight loss among participants assigned to the lifestyle intervention alone. The authors report that addition of a wearable technology to a standard behavioral weight loss intervention resulted in less weight loss over 24 months.
