Many thyroid suffers look to the LCHF diet. Like with most people, there are benefits to being on the diet, whatever your condition. On this episode of the LCHF Podcast, Dr Gary Fettke gets quizzed specifically on an underactive thyroid. Is the LCHF diet the answer?

Transcript

Brad Brown: This is the LCHF podcast and question in today from Sedia and we’ve got Dr Gary Fettke on the podcast once again. Doc, welcome back, nice to chat. Sedia was saying, she’s 40 years old, she has an underactive thyroid and she’s been following the LCHF diet for about five weeks. She’s only lost 1kg, she wants to know, is she doing something wrong or is this diet not suitable for someone who has thyroid disease?

Gary Fettke: As we’ve mentioned before, we can’t really give individual advice on this podcast Brad, so I always recommend that patients or individuals definitely work with their treating doctor on this to make certain that there’s nothing else funny going on, or some other disease process and check that out first of all.

Thyroid diseases tend to be autoimmune

In principle, thyroid diseases tend to be autoimmune. In the modern diet, which is high in sugars, carbohydrate and polyunsaturated oils; I think that puts them at risk for it, at least the concept is along that line. Can we cure thyroid disease, autoimmune disease of the thyroid by adopting a LCHF lifestyle? I don’t think so, but you might in fact give it a chance for the body to heal itself over a long period of time.

There is some reading at the moment that your thyroid function dropping down is in fact a more primitive state, so that in anthropological evidence, then having an underactive thyroid may in fact have some protective benefits.

We tend to get caught up on hypothyroidism and hyperthyroidism, that’s a thyroid dysfunction, not enough or a thyroid that’s over functioning and the thyroid is clearly involved in metabolism. Some people who are actually going LCHF have actually found their thyroid function to drop down a bit. So it’s still a complex issue.

I’ve got to openly admit, I don’t think we’ve got the full answer on exactly what happens to thyroid function once you start low carb healthy fat, but if you already have an underactive thyroid, it doesn’t seem to be doing any harm.

You should still feel the benefit of the LCHF diet

So, the benefits of running LCHF is that you’re generally feeling better, you’ve got more energy levels and that certainly helps the people who have got underactive thyroid. What happens to their metabolic rate, well I think that she’s only been going for a few weeks here. I think this is early days for her and rather than actually think that LCHF is or isn’t working, I’d actually be going back to her portion sizes.

So I’d be getting a good, clear understanding of exactly how much  she’s cutting carbohydrates down and as we’ve talked about in previous podcasts, make certain she’s not actually replacing that with too much fat. It’s getting those portions right that is probably more important than worrying about where her thyroid is actually going up or down at the moment.

Again, if Sedia has got an issue with her thyroid, she shouldn’t be just doing this LCHF and changing major things in her life without the guidance of her own treating doctor.

BB: Absolutely fabulous advice, Dr Gary Fettke, thank you very much, Sedia, good luck on your journey. If there is anything else we can help you with, be sure to be in touch. You can get to the website, lchfpodcast.com, you can submit your question there and we look forward to chatting again next time here on the podcast. From myself Brad Brown and Dr Gary Fettke, it’s cheers.
