To not understand why my healthy (I think) way of eating isn't making me feel energetic and fabulous

TSH is the thyroid stimulating hormone, it tells the thyroid to produce t4 and is regulated by the pituitary gland

why do you think my interpretation of the relationship between TSH and t4 is confused

I stopped taking any notice when you wrote: All carbs are heavily processed and refined, and have minimal nutritional value.

REALLY?

I'm not getting what you mean here. I think your interpretation of the relationship between TSH and T3/T3 is confused. But it isn't clear from the way you've phrased it. Can you explain further?

The only thing with sugar in the smoothie is the banana and the fat from the avocado and peanut butter will slow down its absorption. So no, definitely not high in sugar. Moderate at most.

Peanut butter on sourdough is not high in sugar either and definitely healthier than a upf rice cracker.

You have proved with your previous apparent inability to distinguish complex carbohydrate from Kit Kats, that you are no more competent to weigh evidence than any of the other people, including those with clearly disordered eating, on this thread.

If you google, there are plenty of studies. While the evidence is too scant to draw large scale conclusions, the overall opinion seems to be that a low carbohydrate diet, as part of an AIP protocol (which is meant to be a short term measure), may reduce inflammation. The downside is that studies also seem to show that while a low carb diet might be beneficial in terms of TSH, it can also reduce circulating T3. As anyone who is hypothyroid will tell you, T3 is much more relevant to who you feel than TSH, which is a broad brush marker. It also helps to differentiate between what might benefit people who have elevated levels of TPOAb and TgAb but are not yet hypothyroid and people who are already hypothyroid.

Both my consultant endocrinologist and my mother, who is a doctor, feel that on balance, the evidence is, if you are already hypothyroid, a keto or very low carbohydrate diet is not recommended. By that, they of course, do not mean that people should be wolfing down the foods that you seem to believe represent the whole of the carbohydrate food group.

😂🤣😅
Egg recommendations vary over the years. A GP once said no more than 3 a week. The BHF says no more than 1 a day.
Same with red wine, sometimes there are advisory notes saying dont drink it, sometimes its good for your heart!
Now chocolate eggs-as many as you like!!😁😅🤣

That study says EXACTLY the opposite. That carbs have a negative effect on thyroid function and high protein and fat a positive effect. I don't want to be a dick, but it proves you flat out wrong. Am I missing something about your point?

its not the opposite though, its not straight forward, there are three measurements of the thyroid and different outcomes

TSH high GI foods have a negative affect
T4, T3 High GI foods have a positive affect

high protein and saturated fats have a negative affect on T4 and T3

In our study, frequent consumption of foods with a high glycemic index showed a positive association with fT3 and fT4 levels and a negative association with TSH levels, whereas foods rich in saturated fatty acids and with a high protein concentration showed a negative association with fT3 and fT4 levels

so the high glycemic foods are negative on TSH and positive on T3 & T4, so as TSH is the cue that lets out T4 thats not good and T4 produces T3

but protein and saturated fatty acids are negatives on T3 and T4 which isn't great

Well, you're the one who made the claims I listed above, and you're also now claiming that you are competent to weigh the evidence and draw those conclusions, so I'm asking you for your sources for the above specific claims, as you did to someone else earlier in the thread.

I would suggest that making such claims without being willing to back them up because it's not "[your] turn" is the opposite of posting in good faith, but then I'm a big believer in the maxim he who asserts must prove.

It's not my turn. I'm not seeing anyone else backing up their points with good evidence and it's unreasonable to insult my argument and discredit me, when I am the only person who has backed up a claim with reputable evidence. It's fair to ask me to, and I will post in good faith. But I ask for investment from others in return.

Also, as you seem to have omitted it, I have added I mean starchy grains and not fruits and vegetables.

I am absolutely not a nutritionist, but given that all grains come from plants (ie they are natural) and that grains of one kind or another have been eaten for thousands of years by all civilisations, and that we are all the descendants of people who have survived and reproduced for years while sustaining themselves eating grains, I think it's safe to say that grains have some nutritional value.

Ok, now do these claims:

"[carbs] have nothing you need"
"[carbs] are not a natural food group"
"all carbs are heavily processed"
"grains ... really do have limited nutritional value"

Yes. That is a an Internet page peddling product. It is not a source you should depend on to evidence a point. The actual quality evidence posted by mistake says the complete opposite. And not only supports my point that carbs are bad, but also that I am competent to draw that conclusion and weigh evidence, and critique a source. And if you think that page is a good source you definitely aren't. Which would be fine - we all have different skills - but you are saying you are and I'm not and am posting 'insane' things.

That is a poor quality internet page written by a firm selling a diet and thyroid products. It over simplifies both carbohydrate metabolism and thyroid function to the point of misrepresentation. It's not wrong, necessarily. But it's biased, incomplete, basic, poorly contexted and meant to sell products for personal gain. It IS referenced, and I'll check them out. But it's NOT a reputable source itself and even says the study it draws on is small. Giving it equal weight to the first article you linked is exactly people's point about how just anyone can't evaluate this information and conclude with authority. Source matters. Knowledge matters. Context matters.

The article you mistakenly linked WAS a reputable source. It was a large study, by a large team, published a reputable journal, vetted by other scientists, not selling anything. It was quality evidence and should COMPLETELY refute the first source if they are contradictory, even if the references check out (especially if the references check out, actually). This is exactly the problem that others are saying I'm an example of - authority without knowledge or evidence. And here we are, with my point supported both in terms of facts and process.

What happens if you don't have a thyroid?

This is an article written for lay person reading, but there are attributions to clinical studies at the end.

Aren't you the poster who said that utterly insane shit about carbohydrate earlier in the thread?

Are both things that some people eat and others don't. The OP, for example, doesn't eat meat, and said that in her OP.

Here’s a breakdown of the minerals and vitamins in oats

• Manganese. Typically found in high amounts in whole grains, this trace mineral is important for development, growth, and metabolism.
• Phosphorus. This mineral is important for bone health and tissue maintenance.

• Vitamin B1. Also known as thiamine, this vitamin is found in many foods, including grains, beans, nuts, and meat.
• Iron. As a component of hemoglobin, a protein responsible for transporting oxygen in the blood, iron is absolutely essential in the human diet.
• Selenium. This antioxidant is important for various processes in your body. Low selenium levels are associated with increased risk of premature death and impaired immune and mental function.
• Magnesium. Often lacking in the diet, this mineral is important for numerous processes in your body.
• Zinc. This mineral participates in many chemical reactions in your body and is important for overall health.

Red meat, fermented foods

Of course grains are a natural food. They're not made in a lab, and we've been eating them for the entirety of human history.

Nobody is saying UPFs are healthy.

But I do believe complex carbs have a place in a healthy diet. I’ve just had some quinoa for lunch. Are we trying to claim that that’s not healthy?

They are nutrient dense and also
a source of fibre. They provide energy and can help with bad cholesterol..

I mean grains. They really do have limited nutritional value

But according to various sources, whole grains such as brown rice are a source of fibre, protein, vitamins b1, b2, b3, b5, and b6, iron, folate, magnesium, phosphorus, zinc, copper, manganese, selenium, potassium, calcium, and phenols/flavonoids. Are you saying none of this is true?

Plenty of protein here - milk, yogurt, cheese, eggs, nuts, oily fish.
