I left off last time saying we would look at the effects of low carb/ketogenic diets on thyroid function. Thyroid function is a hotly debated topic in the low carb world. While most people typically experience fat loss, better energy levels, and improved overall vitality on a low carb diet, in some individuals, measurements of thyroid-related hormones suggest that a low carbohydrate intake might be having adverse effects on the thyroid gland. Is it possible that a way of eating that has such wonderful benefits for so much of the body could be harmful for the thyroid?

At first glance, we might take this to mean that low carb causes a slowdown in metabolism, or maybe it has other negative downstream effects. On the other hand, physicians and researchers who’ve spent decades improving the lives of their patients with low carb and ketogenic diets . So what’s the deal?
