VLCD intervention significantly increases Sex-Hormone-Binding Globulin (SHBG) and reduces fasting blood glucose in obese women with PCOS, whereas moderate energy deficit does not significantly alter these specific metabolic markers over 8 weeks.
VLCDs offer a metabolic advantage over moderate dieting for PCOS patients by significantly boosting SHBG and lowering fasting glucose. This suggests VLCD may be necessary to reverse the underlying insulin resistance driving hyperandrogenism in some patients.
GoodSupportsMEDIUM confidence
In the VLCD arm, two women (18%) had a biochemical remission of PCOS (FAI < 4)... There was a significant within-group increase in the sex-hormone-binding globulin (p = 0.002) and reductions in fasting blood glucose (p = 0.010)... in the VLCD arm, but not in the energy deficit arm.
Why this rating
RCT data, but small sample size limits statistical power for secondary endpoints.
