Abstract

This study aimed to summarize earlier randomized controlled trials on the effects of ketogenic diet (KD) on body composition and anthropometric measures. Four databases were searched from inception to May 2020 using relevant keywords. All clinical trials investigating the effects of KD on body weight (BW), body mass index (BMI), waist circumference (WC), fat mass (FM), fat-free mass (FFM), lean body mass (LBM), visceral adipose tissue (VAT) and percentage body fat (PBF) in adults were included. Overall, 18 trials were included in the review. Pooled effect sizes revealed a significant effect of KD on BW (weighted mean differences [WMD]: −2.87 kg, 95% confidence interval [CI]: −3.84 to −1.89), BMI (WMD: −1.44 kg/m2, 95% CI: −2.07, −0.81), FM (WMD: −1.40 kg, 95% CI: −2.50, −0.30), FFM (WMD: −0.81 kg, 95% CI: −1.32, −0.30), LBM (WMD: −0.63 kg, 95% CI: −1.21, −0.06), WC (WMD: −3.23 cm, 95% CI: −4.38, −2.09), VAT (WMD: −28.91 g, 95% CI: −50.57, −7.24) and PBF (WMD: −2.81 kg, 95% CI: −3.82, −1.80), respectively. Taken together, the data suggest that KD has beneficial effects on BW, BMI, FM, FFM, LBM, WC, VAT, and PBF. However, the effectiveness of the long term effect of this dietary pattern is unclear.

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.
