Safety of 8-h time restricted feeding in adults with obesity

Appl Physiol Nutr Metab. 2019 Jan;44(1):107-109. doi: 10.1139/apnm-2018-0389. Epub 2018 Sep 14.


This study examines the safety of time restricted feeding (TRF; 8-h feeding window/16-h fasting window daily) in obese adults. Twenty-three subjects participated in an 8-h TRF intervention for 12 weeks. Self-reported adverse events, body image perception, complete blood count, and disordered eating patterns did not change from baseline to week 12. These findings suggest that consuming food within an 8-h window can safely facilitate weight loss in subjects with obesity.
