Abstract

Background Polycystic ovary syndrome (PCOS), a common condition in women, improves with weight loss. Meal replacements in short-term weight loss and strategies for weight maintenance have not been investigated in PCOS.Objective We compared in overweight women with PCOS the effects of meal replacements in short-term weight-loss and longer-term carbohydrate- or fat-restriction strategies on weight maintenance and improvements in reproductive and metabolic variables.Design Overweight women with PCOS (n = 43; x +/- SD age: 32.1 +/- 5.2 y; weight: 96.1 +/- 18.4 kg) followed an 8-wk weight-loss regimen (2 meal replacements/d, 4904.4 +/- 127 kJ; phase 1) and then a 6-mo weight-maintenance carbohydrate- (<120 g/d) or fat- (<50 g/d) restriction regimen (phase 2).Results Thirty-four women completed phase 1, and 23 women completed phase 2; the proportion of dropouts was similar in the 2 groups. During phase 1, significant (P < 0.05) reductions in weight (5.6 +/- 2.4 kg), waist circumference (6.1 +/- 2.5 cm), body fat (4.1 +/- 2.2 kg), insulin (2.8 +/- 1.1 mU/L), total testosterone (0.3 +/- 0.7 nmol/L), and free androgen index (3.1 +/- 4.6) occurred; these changes were sustained during phase 2. No significant differences between diet groups were seen for any variables. At 6 mo, both approaches resulted in a net weight loss of 4.7 +/- 4.6 kg. Improvements in menstrual cyclicity occurred for 16 (57.1%) of 28 subjects.Conclusions Meal replacements are an effective strategy for the short-term management of PCOS. Advice on moderate fat or carbohydrate restriction was equally effective in maintaining weight reduction and improving reproductive and metabolic variables.

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.
