If you have no thyroid can you still increase your metabolism by eating more often and excercising. etc.. I've tried looking online but can find no answers. I would think that my metabolism would pretty much be a constant because the Synthroid keeps it regulated. I gained so much weight right away after the thyroid removal that it's frustrating. Six months later now I think they're starting to figure out the right dose (200mcg) Just wondering if there's anything I can do to help my metabolism along now, or if it's gonna be set by the Synthroid. Just curious if anyone knows... Thanks.
