Diabetes is an issue for any thyroid patient and it is not specific to the Circadian T3 Method.

All thyroid hormone is active within cells not in the bloodstream. T3 cannot work properly without enough ATP (cellular energy). ATP is made by the mitochondria (one mitochondrion in each cell). ATP needs glucose for it to be manufactured.

Glucose enters the cell because of our diet, our digestive system, our cortisol (which maintains glucose levels) and insulin enables the cell walls to accept glucose. Any imbalance in any of these will stop thyroid hormone working. So, those on a calorie restricted diet may be stopping their thyroid hormones from working properly because their blood glucose never rises enough. Those with insulin issues may not have enough glucose entering the cells.

A glucose tolerance test (GTT) and insulin measurement can identify if there is a glucose or insulin issue.
