any link between low carb-TSH

I was diagnosed with borderline diabetes 5 months before with normal TSH.

So I started following low carb diets .but I observed TSH level also reached to boundary.I searched sites and found link between the two .I had symptoms of

palpitation,muscle cramps,fatigue.also observed when I reduced total calory around 1200 -1400 for (with increased healthy carbs) feel light,energetic,less.please advise

Insulin resistance may cause type 2 diabetes. It has also a direct connection to the decrease of thyroxin hormone level causing hypothyroidism. There is no link between low carbohydrate diet and TSH.

At most laboratories ,. the official reference range for the TSH test runs from approximately 0.5 to 4.5 or 5.0 (mIU/Lof blood). A person whose TSH level is within the reference range is referred to as "euthyroid," and is considered to have normal thyroid function.

When you say you eat low carb diet,it is necessary to know how low is your carb portion of your diet compared to total diet in terms of grams and when you feel okay at what level of carb in terms of grams

Hypothyroidism is becoming increasingly more common in Western countries.One of the main symptoms of this hormone disorder is a slower metabolism and gradual weight gain.

Low carb and ketogenic diets have emerged as popular approaches to weight loss, at least in otherwise healthy individuals. But there is some controversy over the safety of these eating patterns for hypothyroidism.

A low carbohydrate (low carb) diet is any eating pattern that limits carbohydrate consumption.

The standard Western diet is about 50-60% energy carbs, or roughly 300 grams per day. Low-carb diets are typically 30% energy or lower, although there is no set criteria.

However, there is a clear distinction between a low carb diet and a ketogenic diet.

A ketogenic diet (keto diet) is a very-low carb diet that restricts carbs to less than 20-50 grams per day, or less than 10% of total energy intake.

This makes the body switch to ketones for energy – produced from fats – rather than glucose from carbs

Thyroid hormones are essential to maintain and regulate carbohydrate/energy metabolism).

Conversely, the energy (glucose) we get from carbs is required to fuel the production of thyroid hormones.This is because the parts of the brain ultimately responsible for thyroid hormone regulation – the hypothalamus and the pituitary gland – require glucose to function.

In fact, the main regulation hormone, called Thyroid Stimulating Hormone (TSH), is made up partly of glucose molecules.

.

In addition to these important roles, carb intake appears to influence the amount of T3 that gets converted from T4 thyroid hormone. This is important for hypothyroidism as T3 is the active thyroid hormone that you need .to increase..It appears that when carb intake is drastically reduced, conversion of T3 from T4 declines).

This could be explained by the possible interaction between insulin and the enzymes that convert T4 into the T3.

It’s known that a state of prolonged calorie restriction or fasting reduces T3 hormone production.

This occurs to slow down metabolism, increasing chances of survival when our ancestors were in times of food shortage.

Of course, lower T3 (and therefore a slower metabolism) is typically undesirable when food is abundant… especially for those with an underactive thyroid.

A ketogenic diet mimics starvation or fasting, at least from a metabolic point of view.

This means it may limit T3 production and potentially influence metabolism.

Average T3 plasma concentrations after 11 days of high carbohydrate diet (white), control diet (grey) and low carbohydrate diet (black) in 6 healthy males. The * indicates a significantly lower T3 level for the low carbohydrate diet, which is not desirable in hypothyroidism.

These results are similar to those of another study where participants received an 800 Kcal low calorie diet comprising of either 0%, 25% or 100% carbohydrate, for a period of 2 weeks.

The results showed T3 levels were reduced from both fasting and the 0% carbohydrate diet, but not from the 100% carbohydrate diet (11).
