Time-Restricted Eating Without Calorie Counting for Weight Loss in a Racially Diverse Population. A Randomized Controlled Trial and Time-Restricted Eating for Treatment of Obesity? The Devil Is in the (Counseling) Details

(from the August 2023 Annals for Educators)

Time-restricted eating without calorie counting has become a popular weight loss strategy, but long-term randomized trials evaluating its efficacy are limited. This randomized clinical trial examined the effect on weight loss at 12 months of an 8-hour time-restricted eating strategy (without caloric restriction) versus a strategy focused on reducing calories. The accompanying editorial discusses the findings, the important role of counseling in any weight loss intervention, and evidence gaps in what we know about the effectiveness of time-restricted eating.
