Abstract

Objective: In contrast to intentionally restricting energy intake, restricting the eating window may be an option for treating obesity. By comparing time‐restricted eating (TRE) with an unrestricted (non‐TRE) control, it was hypothesized that TRE facilitates weight loss, alters body composition, and improves metabolic measures. Methods: Participants (17 women and 3 men; mean [SD]: 45.5 [12.1] years; BMI 34.1 [7.5] kg/m 2 ) with a prolonged eating window (15.4 [0.9] hours) were randomized to TRE ( n = 11: 8‐hour window, unrestricted eating within window) versus non‐TRE ( n = 9: unrestricted eating) for 12 weeks. Weight, body composition (dual x‐ray absorptiometry), lipids, blood pressure, 2‐hour oral glucose tolerance, 2‐week continuous glucose monitoring, and 2‐week physical activity (actigraphy assessed) were measured during the pre‐ and end‐intervention periods. Results: The TRE group significantly reduced the eating window (end‐intervention window: 9.9 [2.0] hours) compared with the non‐TRE group (end‐intervention window: 15.1 [1.1] hours) ( P < 0.01). Compared with non‐TRE, TRE decreased the number of eating occasions, weight, lean mass, and visceral fat (all P ≤ 0.05). Compared with preintervention measures, the TRE group reduced the number of eating occasions (−21.9% [30.1%]) and reduced weight (−3.7% [1.8%]), fat mass (−4% [2.9%]), lean mass (−3.0% [2.7%]), and visceral fat (−11.1% [13.4%]) (all P ≤ 0.05). Physical activity and metabolic measures remained unchanged. Conclusions: In the setting of a randomized trial, TRE presents a simplified view of food intake that reduces weight.

  • Recent human trials on TRE have highlighted numerous beneficial metabolic effects of TRE, e.g., improved mean daily glucose levels, fasting glucose levels, insulin resistance or insulin sensitivity, triglyceride levels, total cholesterol, and LDL cholesterol levels.

    “Recent human trials on TRE have highlighted numerous beneficial metabolic effects of TRE, e.g., improved mean daily glucose levels (107, 108), fasting glucose levels (108–110), insulin resistance (108, 110, 111) or insulin sensitivity (112, 113), triglyceride levels (107, 109, 114, 115), total cholesterol (115, 116), and LDL cholesterol levels (116).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
