You are more than a lab value.
Lab values are based off tests run in the 1960s based on high carb standard American diet
What is the Thyroid?
TSH secreted by Pituitary Gland (in your brain)
TSH stimulates the thyroid gland (in your neck)
A gland that secretes hormones
Two main hormones T4, T3
Thyroid function is measured by measuring TSH, T4, T3
Influences fertility, energy, metabolism, body temperature regulation, blood lipids, It
controls the metabolic rate of every organ in the body
You die without a thyroid
Disorders of Thyroid
Hypothyroidism (more common)
People often take levothyroxine
Hyperthyroidism (too much thyroid hormone)
Does diet influence thyroid?
Absolutely, but why?
E.G if you are in famine, you wouldn’t want to have baby, you would want to slow
your metabolism etc.
Any change in environmental stimuli / lifestyle may affect thyroid
Diet is no exception
T3 increases as carbs increase
(To help metabolise carbohydrates)
When you decrease carbs, T3 decreases
If your on meds, you will need a change
Like Coumadin. Its neither bad nor good just a change
Is this bad? Maybe maybe not
Anecdotally, people do report change in thyroid function when going from SAD to KETO, the question is why?
All these things may lower metabolism to conserve energy.
IT ALL COMES DOWN TO HOW YOU FEEL
If you feel great, who cares what your thyroid panel comes back at
If you don't feel right and your thyroid panel is abnormal and you have a history of thyroid issues, adjust medication as needed
Work with your physician.
When changing anything in your environment your thyroid medication MAY need to be changed so you might needs labs checked every 2 week
What does the research show?
Most studies are on rats
Most studies that look at low carb, high fat use PUFAs (corn oil, safflower)
Let’s remind everyone WHY we don't eat veggie oils EVER!
Rats on a safflower oil diet have a more greatly reduced metabolic response to T3 than rats on a beef fat diet.
Let's remind everyone WHAT brown fat is
Rats on a long-term diet high in soybean oil have terrible body temperature regulation, which thyroid function in large part controls.
Let's remind everyone WHY we don't eat soybean oil
The more rapeseed meal (from which PUFA-rich canola oil is derived) you feed turkeys,
This reduced thyroid signaling isn’t a function of all polyunsaturated fats, however.
What about a study on Humans?
Jeff Volek ran a low-carb, high-fat study in adults using a diet with Primal-ish fatty acid ratios (8% carbs, 61% fat, 30% protein, with 25% calories coming from SFA, 25% from MUFA, and 11% from PUFA). He didn’t directly measure T3, but the high-fat group had normal T4 and lost significant body fat, which is very hard to do if you’re hypothyroid.
If you have thyroid issues, recognize keto might not work for you. Maybe try LCHF
Lower carbs without ketosis does not influence thyroid function usually
With LCHF you have many of the same benefits with the unlikely result of influencing thyroid
