The aim of this study was investigated the effects of fennel supplementation with energy-restricted diets on body fat and muscle percentage and insulin resistance in women with PCOS. Sixty-four overweight/obese women with PCOS were randomly allocated to 4 groups for 12 weeks as follows: (1) standard diet + fennel (SDF), (2) high-protein, low-carbohydrate diet supplemented with fennel (HPF), (3) standard diet + placebo (SDP), and (4) high-protein, low-carbohydrate diet + placebo (HPP). After 12 weeks of intervention, there were significant changes in the percentage of body fat and muscle in all groups. Decreasing in fasting insulin was −4.12 micIU/ml (P = 0.01) for HPF and −4.5 micIU/ml (P = 0.03) for SDP groups. In addition, HOMA-IR significantly decreased in HPF (P = 0.02) and SDP (P = 0.02) groups. Energy-restricted diets independent of dietary composition improved the body fat and muscle percentage and insulin resistance indices in women with PCOS. High-protein diet and fennel compared with standard diet and placebo had no significant effect on insulin resistance, body fat and muscle.

这项研究的目的是调查补充能量受限饮食的茴香对PCOS妇女体内脂肪和肌肉百分比以及胰岛素抵抗的影响。将64名PCOS超重/肥胖妇女随机分为4组，每组12周，具体方法如下：（1）标准饮食+茴香（SDF），（2）补充茴香（HPF）的高蛋白，低碳水化合物饮食， （3）标准饮食+安慰剂（SDP），以及（4）高蛋白，低碳水化合物饮食+安慰剂（HPP）。干预12周后，所有组的体内脂肪和肌肉百分比均发生了显着变化。HPF空腹胰岛素减少为-4.12 micIU / ml（P = 0.01），SDP组减少为-4.5 micIU / ml（P = 0.03）。此外，HPF（P = 0.02）和SDP（P = 0.02）组的HOMA-IR显着降低。与饮食组成无关的能量受限饮食可改善患有PCOS的女性的体内脂肪和肌肉百分比以及胰岛素抵抗指数。与标准饮食和安慰剂相比，高蛋白饮食和茴香对胰岛素抵抗，体脂和肌肉没有显着影响。
