Yes, this. I dont have insulin resistence but my 16yo daughter does. We went thru months of testing and three different drs before the last one did a glucose tolerance test and finally said yes she has insulin resistence. She has been on metforim for 9 months now and along with a low carb diet she has finally lost over 50pounds. She still wants to loose another 45pounds or so. I am so thankful for her current dr because my daughter was so depressed about her weight before, she had been eating low carb and exercising for 5months and had lost nothing until she started the metforim
