When I told my family doctor last year, he said "You will lose, but you will put it all back on, better to go with the low fat diet, because you have high blood pressure.....yada, yada, yackety, schmakety. About 30 pounds lost later, I was diagnosed with thyroid disease, had a bout of thyroiditis, and dx'd with hypothyroid. Then I was sent to an endocrinologist. I almost fell off my chair when he told me to stay on this plan for life!!! I told him my family doc's feelings and he called him, and explained the entire thing!! I have gone on to lose almost to my goal, which I no longer think is 111 lbs, by the way, I'm looking pretty good at 119. No more blood pressure pills, and they haven't even started me on any thyroid meds, and I still lost the weight, and had lots of energy despite my thyroid diagnosis.
