I've read on various health sites that the symptoms for insulin resistance and having an underactive thyroid can be really similar. I suspect I may have hypothyroidism, but it worries me that I might be becoming insulin resistant from my low fat/higher carb (which also means higher sugars) diet.
Aside from seeing a doctor and getting tests done (not possible at the current time), is there any way to get a better idea to distinguish between the two? What are the major differences?
