Abstract

Objective To compare the effects of protein vs. simple sugars on weight loss, body composition, and metabolic and endocrine parameters in polycystic ovary syndrome (PCOS).Design A 2-month, free-living, randomized, single-blinded study.Setting University PCOS clinic.Patient(s) Thirty-three patients with PCOS.Intervention(s) To achieve a final energy reduction of 450 kcal/day, first the daily energy intake was reduced by 700 kcal; then a 240-kcal supplement containing either whey protein or simple sugars was added.Main outcome measure(s) Changes in weight, fat mass, fasting glucose and insulin, plasma lipoproteins, and sex steroids.Result(s) Twenty-four subjects (13 in the simple sugars group and 11 in the protein group) completed the study. The protein group lost more weight (-3.3 +/- 0.8 kg vs. -1.1 +/- 0.6 kg) and more fat mass (-3.1 +/- 0.9 kg vs. -0.5 +/- 0.6 kg) and had larger decreases in serum cholesterol (-33.0 +/- 8.4 mg/dL vs. -2.3 +/- 6.8 mg/dL), high-density lipoprotein cholesterol (-4.5 +/- 1.3 mg/dL vs. -0.4 +/- 1.3 mg/dL), and apoprotein B (-20 +/- 5 mg/dL vs. 3 +/- 5 mg/dL).Conclusion(s) In patients with PCOS, a hypocaloric diet supplemented with protein reduced body weight, fat mass, serum cholesterol, and apoprotein B more than the diet supplemented with simple sugars.

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.
