Am J Clin Nutr. 2007 Mar;85(3):688-94. http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=pubmed&cmd=Retrieve&dopt=Abst ractPlus&list_uids=17344488&itool=pubmed_DocSum Common characteristics of PCOS (insulin resistance, infertility, hirsutism) improve with even modest weight loss. Optimal dietary treatment for PCOS is not known. The objective of the study was to compare the effects of acute protein administration with those of glucose challenges on hormones related to obesity and insulin resistance (ie, cortisol and insulin), hirsutism [ie, dehydroepiandosterone (DHEA) and androstenedione], and hunger (ie, ghrelin). The study found glucose ingestion caused larger fluctuations in blood glucose and more hyperinsulinemia than did protein. Both glucose and protein suppressed ghrelin. The study concluded glucose ingestion caused significantly more hyperinsulinemia than did protein, and it stimulated cortisol and DHEA. Protein intake suppressed ghrelin significantly longer than did glucose, which suggested a prolonged satietogenic effect. These findings provide mechanistic support for increasing protein intake and restricting the simple sugar intake in a PCOS diet. ************************************** See what's free at http://www.aol.com.

The patients were divided into 2 groups. The lean group had BMIs between 18.5 and 24.9. The obese / overweight group had BMIs between 25 and 40. Higher blood pressure, insulin resistance indices, triglycerides and free testosterone were found in the overweight / obese group. Lower HDL levels were also found in that group. The study concluded obesity is associated with insulin resistance and diabetes mellitus in PCOS. The absence of correlation between the IR indices and the FT with the lipidic profile suggests that other factors, such as the free fatty acids, can be involved in the pathogenesis of dyslipidemia in PCOS ************************************** See what's free at http://www.aol.com. -------------- next part -------------- An HTML attachment was scrubbed...
