A range of studies showed confusing data about the relationship between obesity, weight reduction and circulating total insulin-like growth factor -1 (IGF-1). The aim study was to compare influence orlistat (IO), metformin (IM), or calorie-restricted diet (LC) on IGF-1, with special respect insulin-resistance status. One hundred fourteen obese women aged from 18 40 years were divided into insulin sensitive (IS) resistant (IR) groups received a low calorie (LC), an isocaloric 500 mg twice...
