Abstract

Background: Time restricted feeding decreases energy intake without calorie counting and may be a viable option for weight loss. However, the effect of this diet on body weight in obese subjects has never been examined.

Objective: This study investigated the effects of 8-h time restricted feeding on body weight and metabolic disease risk factors in obese adults.

Design: Obese subjects ( = 23) participated in an 8-h time restricted feeding intervention (ad libitum feeding between 10:00 to 18:00 h, water fasting between 18:00 to 10:00 h) for 12 weeks. Weight loss and other outcomes were compared to a matched historical control group ( = 23).

Results: Body weight and energy intake decreased in the time restricted group (-2.6% ± 0.5; -341 ± 53 kcal/d) relative to controls over 12 weeks ( < 0.05). Systolic blood pressure decreased in the time restricted feeding group (-7 ± 2 mm Hg) versus controls ( < 0.05). Fat mass, lean mass, visceral fat mass, diastolic blood pressure, LDL cholesterol, HDL cholesterol, triglycerides, fasting glucose, fasting insulin, HOMA-IR, and homocysteine were not significantly different from controls after 12 weeks (no group×time interaction).

Conclusion: These findings suggest that 8-h time restricted feeding produces mild caloric restriction and weight loss, without calorie counting. It may also offer clinical benefits by reducing blood pressure.
