Evaluating the Influence of Diet-induced Weight Loss on Fat (Adipose) Tissue's Insulin Sensitivity and Testosterone Synthesis in Women With Overweight or Obesity, Insulin Resistance, and Hyperandrogenemia

The investigators will measure plasma concentrations of the hormones insulin and testosterone as well as measures of insulin sensitivity in women with overweight or obesity who have insulin resistance (IR). Women who meet these criteria that also have elevated total or free testosterone will be eligible to participate in the diet intervention. The dietary intervention is designed to produce a 5% reduction in starting body weight to test whether weight loss will acutely lower fasting insulin and testosterone concentrations.
