Keto diet was earlier used to reduce and treat seizures in children, recently keto diet has overtaken the popular diets such as Atkins and Intermittent fasting and is one of the trending diets worldwide.

Before that let’s understand what is Keto diet. Keto diet is nothing but high fat, moderate protein and low carbohydrate diet which has shown promising results for people who want to lose weight, studies also show that keto diet are used for therapeutic purpose like treating epilepsy, diabetes, cancer and Alzheimer’s disease. But keto diet and hypothyroidism? You must be wondering how can this be right? It’s definitely possible, before that let’s look into the aspects of how keto diet work.  

How does Keto diet work? 

Keto diet drastically reduces your carbohydrate intake by replacing it with fat. This adaptation lets your body switch the main fuel from carbs to fat, this switch over helps you attain a state called ketosis. This state helps the body to burn fat efficiently by producing ketones for energy. This makes the body assume that a person is fasting, but actually you’re not the process is known as fasting mimicking.  

Benefits of keto diet  

  • Helps you lose excess fat 
  • Increased ketones in the body reduces the blood sugar levels and improves insulin sensitivity.  
  • Helps in reduction of Blood pressure and triglyceride levels 
  • Improves results of traumatic brain injury, used in the treatment of epilepsy in children, reduces the symptoms of Alzheimer’s and delays its progression.

What Hypothyroidism does to your body?  

Hypothyroidism is a condition where thyroid hormones are not sufficiently produced which slows down your metabolism makes you feel lethargy and tired, leads to weight gain and intolerance to cold temperatures.  

Stress can be one of the underlying causes of hypothyroidism. Stress can elevate hormones such as cortisol and adrenaline, which suppresses the thyroid function which further reduces liver detoxification generating toxins in the body and reduces the gut function leading to increased inflammation. This vicious cycle ultimately ends with stress again and worsens the condition.  

So, finally you must have got a better understanding about why you have been facing issues like bloating, constipation, sluggishness, tired and fatigued constantly. Yes, Stress is the main culprit so be stress free 😊  

Now, let’s see the role of Keto diet in hypothyroidism 

Does Keto diet help with hypothyroidism? 

As we know the knack of keto diet is fasting mimicking diet, but we are not actually fasting. During the keto diet, the body produces ketones, which potentially lowers inflammation, boosts the metabolism, supports muscle function and lowers body fat.  

In hypothyroidism, to achieve normal thyroid levels, T3 has to rise. But through keto diet your T3 levels go down but the person just feels right and excellent. The knack here is though your T3 levels remain low, the ketones produced are just doing right for your body.  

You’ll see improvements in the following symptoms related to hypothyroidism when you’re on keto diet: 

  • Skin health: you might have been experiencing dry skin, acne related issues if you have hypothyroidism, but I must say keto diet has a positive impact on your skin due to inclusion of healthy fat sources and reduced sugar consumption. 
  • Fatigue: Studies have shown that keto dieters have seen improvements in focus and energy on a long-term basis. 
  • Depression/poor memory: Research shows that by following keto diet, one can improve their symptoms related to depression and also enhances memory function.  
  • Digestive issues: though some studies are contradictory, keto diet aids in gas related issues, stomach cramps and lowers acid reflux.  

How to start Keto diet with Hypothyroidism? 

  • Switching the main fuel: Move from carbs to fats for your energy. By gradually lowering the carbs you’re lowering the insulin too. And the best part is you get access to your fat stores where you can efficiently burn them off.  
  • Moderating protein intake: Protein intake can be considered based on the age and weight. Protein also contributes to rise in insulin levels so make sure the intake is in moderate amounts.  
  • High in fat: interesting fact about keto diet is the liberal intake of fat. Let me give you a word of caution, by liberal quantity I mean the liberal intake of healthy good sources of fat.  
  • Vitamins and Minerals: Make sure to take your supplements if you are deficient in any vitamins/minerals like iodine, zinc, vitamin D etc. which are important for thyroid function. Now that you know how to start the keto diet, you must be wondering about the quantity of fat, carbs and proteins you should be taking if you are on a keto diet 

Now that you know how to start the keto diet, you must be wondering about the quantity of fat, carbs and proteins you should be taking if you are on a keto diet

For a person with 2000 calorie diet: Go for 165g of fat, 75g of protein, 40g of carbohydrates. Yes, that’s a lot of fat! And that’s how keto diet works.
