I have been taking 75mcgs of T3 only for two and a half years. I have felt almost back to normal on it but I cannot lose weight. In fact, I am steadily gaining it! I take iron and all the supplements I am supposed to for good health. But the only way I can stop the scales steadily creeping up is to eat one meal a day. This leaves me miserable, as you can imagine. I am quite fit and walk between twenty and twenty five fast miles a week with my husband and our dogs. I am utterly mystified as to why my weight continues to creep up. Can anyone shed any light on this, please?
