Main Outcome Measures. Serum total and free thyroxin (T4), total and free T3, reverse T3, TSH (TSH) concentrations.

I guess it saying the T3 levels of croners are lower, not abnormal. So its a eat less, burn less strategy, with the eating less having the health benefits. Thats kind of interesting though that you can still feel good with lower T3 and not have hypo side effects. So do croners have healthy offspring if they do that whle pregnant?

Sorry to ask this, I know you must have said this before, how did you choose your calorie level for this?
