I've lost almost 20 lbs in 3 months. I lost most of it without trying to and now that I'm exercising more I'm losing more. I exercise to burn off the energy. Although I have seen that I'm eating more often, just lesser amounts of food. I know my thyroid is at a normal level and most of my meds say weight gain, so I don't have any answers lol. If they want you to gain weight then I would say just start enjoying more food lol
