"I'm not saying under-eating is the root cause over everyone's hypothyroid or that it's the only cause. Just saying it's the root cause to the majority of the people's hypothyroid in the AF section. "
That's pretty much exactly what you are saying when you write this:"Under-eating > hypothyroid > "AF" symptoms"
and this: "Hypothyroid is the direct cause of most of the so-called "AF" symptoms. Under-eating is the root cause of most people's hypothyroid."
and this as well: "What you are seeing is most of these so-called "AF" symptoms are directly caused by hypothyroid which was caused by prolonged calorie-restriction."
"Almost everyone in the AF section has a history of calorie-restriction"
How do you know? What constitutes "almost everyone"? I'd love to see these statistics!
