The health care industry is full of these kind of shenanigans. I recently cut out sugar and grains from my diet. Now I am eating a high fat, low carbohydrate, and moderate amount of protein. I feel fantastic and have lost over 40 pounds (~18 kg) so far. I also have Hashimoto's Thyroiditis, and was told by the endocrinologist that it will be more difficult to lose weight now. I can't wait to see his reaction in June when I go in for my yearly check up with him.
