Hyperinsulinemia is believed to contribute to or worsen all of these conditions, and increases androgens in women with PCOS. Carbohydrates are the main stimulators of insulin release, but research shows that dairy products and starches elicit greater postprandial insulin secretion than non-starchy vegetables and fruits. The purpose of this study was to determine whether an 8-week low-starch/low-dairy diet results in weight loss, increased insulin sensitivity, and reduced testosterone in women with PCOS. METHODS: Prospective 8-week dietary intervention using an ad libitum low starch/low dairy diet in 24 overweight and obese women (BMI≥ 25 kg/m(2) and ≤ 45 kg/m(2)) with PCOS. Diagnosis of PCOS was based on the Rotterdam criteria. Weight, BMI, Waist Circumference (WC), Waist-to-Height Ratio (WHtR), fasting and 2-hour glucose and insulin, homeostasis model assessment of Insulin Resistance (HOMA-IR), HbA1c, total and free testosterone, and Ferriman-Gallwey scores were measured before and after the 8-week intervention. RESULTS: There was a reduction in weight (-8.61± 2.34 kg, p<0.001), BMI (-3.25± 0.88 kg/m(2), p<0.001), WC (-8.4± 3.1 cm, p<0.001), WHtR (-0.05± 0.02 inches, p<0.001), fasting insulin (-17.0± 13.6 μg/mL, p<0.001) and 2-hour insulin (-82.8± 177.7 μg/mL, p=0.03), and HOMA-IR (-1.9 ± 1.2, p<0.001) after diet intervention. Total testosterone (-10.0± 17.0 ng/dL, p=0.008), free testosterone (-1.8 pg/dL, p=0.043) and Ferriman-Gallwey scores (-2.1 ± 2.7 points (p=0.001) were also reduced from pre- to post-intervention. CONCLUSION: An 8-week low-starch/low-dairy diet resulted in weight loss, improved insulin sensitivity and reduced testosterone in women with PCOS. Article Published Date : Mar 31, 2015

Influence of a fermented protein-fortified dairy product on serum insulin-like growth factor-I in women with anorexia nervosa: A randomized controlled trial.

Clin Nutr. 2016 Oct;35(5):1032-8 Authors: Trombetti A, Carrier E, Perroud A, Lang F, Herrmann FR, Rizzoli R Abstract BACKGROUND & AIMS: Patients with anorexia nervosa (AN) have low serum IGF-I levels that may contribute to a lower bone mineral mass. We investigated the effects of a fermented, protein-fortified, dairy product on serum IGF-I levels in patients with AN during an in-hospital refeeding program. METHODS: In this multicenter, randomized, double-blind, placebo-controlled, clinical trial conducted at 3 university hospitals and 3 private clinics in France and Switzerland, 62 women recently admitted with confirmed AN and with a baseline low serum IGF-I level were randomized to 2 daily isocaloric fresh cheese pots containing either 15 g/150 g or 3 g/150 g (controls) of protein for 4 weeks. The primary outcome was the change in IGF-I levels. RESULTS: In the primary intention-to-treat analysis, mean serum IGF-I levels increased during the intervention phase from 22.9 ± 1.5 to 28.6 ± 1.3 nmol/L (means ± SEM) (+20.2%) in the intervention group and from 20.2 ± 1.2 to 25.7 ± 1.5 nmol/L (+16.8%) in controls. In a preplanned analysis of covariance with repeated measures, the between-group difference was close to statistical significance (P = 0.071). In a post-hoc mixed-regression model analysis, the difference was statistically significant (4.9 nmol/l increase; P = 0.003), as was the change of the ratio IGF-I/IGF-BP3 (P=0.004). There was no between-group difference in biochemical markers of bone turnover (osteocalcin, P1NP, CTX) or in serum parathyroid hormone level. Serum calcium levels slightly increased during the intervention phase in the higher protein group (P = 0.02). IGF-BP2 decreased significantly more in the intervention group during the follow up period at week 4 after supplements cessation (P = 0.019). CONCLUSIONS: Intake of a fermented, protein-fortified, isocaloric dairy product during 4 weeks may slightly increase serum IGF-I levels in women with AN, without significant changes in bone turnover markers.
