Psychological benefits of a high-protein, low-carbohydrate diet in obese women with polycystic ovary syndrome—A pilot study
Abstract
This study compared the psychological effects of a low-protein high-carbohydrate (LPHC) diet and a high-protein low-carbohydrate (HPLC) diet in women with polycystic ovary syndrome (PCOS). Twenty-five overweight women with PCOS were matched for age, weight, and whether they were trying to conceive. They were randomly allocated to the LPHC or HPLC diet for 16 weeks. All participants attended a weekly exercise, group support and educational program. The Hospital Anxiety and Depression Scale and the Rosenberg Self Esteem Scale were administered at the beginning and end of the study. The HPLC diet was associated with significant reduction in depression and improvement in self-esteem. There was no change in any psychological measures for the LPHC group. There was no difference in weight loss between the groups. Due to enhanced feelings of well-being, it is possible that HPLC diets may be associated with better compliance and hence be more successful in the long term treatment of obesity.

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.
