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.

Objectives Time restricted feeding (TRF) is a novel approach to intermittent fasting which
includes a 4–10 hour feeding window and a 14–20 hour fasting window daily. However, the
safety of TRF has yet to be determined. This study was undertaken to determine the effects
of TRF on certain safety parameters, including: eating disorder symptoms, body image
perception, complete blood count, resting metabolic rate, and frequency of adverse events,
in adults with obesity. Methods Adults with obesity (n= 23) participated in an 8-h TRF …
