No thyroid, no problem. Think of your lack of thyroid diet similar to that of hypothyroidism. They have very similar characteristics in the symptoms that may occur. Weight gain, difficulty sleeping, feeling tired, and constipation are symptoms that diet can help manage.


Fibrous beans and legumes will help with constipation.

Dairy products fortified with vitamin D can aid with calcium and vitamin D intake to help minimize deficiencies.

Fresh fruits are full of antioxidants to help reduce inflammation.

Vegetables, starchy and non, are an option for a healthy plate and to help avoid vitamin deficiencies.

Lean protein such as chicken, turkey, fish, eggs, etc. are a great way to fill you up and avoid snacking or overconsuming on other foods.

Seeds and nuts help with heart health, are a good fat and protein choice.


This list looks like everyday eating or even the Mediterranean diet, and honestly it is very similar. Weight gain is a very common symptom but is manageable with a plan for your diet and exercise.



Let’s look at a few foods we want to limit.

Coffee. Caffeine in the afternoon, of any type, is not going to help you as much as you think. Lack of a thyroid may make you feel tired, however increasing caffeine can cause sleep disturbances later on that night.

High sugar. If your metabolism is slowing down the chocolate cake is not going to add value to your current lifestyle. Look for foods high in nutrients.

High fat. One symptom is an increase in your cholesterol so to help your heart and lipid panel out we want to reduce fried and highly processed foods.

Alcohol. Let’s be honest what diet tells you to drink any alcohol you want, and it will work wonders for you? Limit alcohol consumption due to excess calorie consumption and blockage of nutrient absorption.


Depending on the medication you are taking there can be what's called a food drug interaction. Meaning certain types of foods may decrease the absorption of the medication. Levothyroxine may be decreased by foods such as soybean flour, cotton seed meal, walnuts, dietary fiber, calcium, and calcium fortified juices. These foods should be avoided within several hours of dosing if possible. Also, multivitamins with iron have a moderate food drug interaction.



Supplements are another item to be mindful of with medications. Certain types and high doses of supplements may alter blood work results. Let your doctor know anything you are taking.



Weight loss will be one of the biggest hurdles you may face. Weight loss is not cut and dry- if I don’t eat this many calories, I will lose weight. Setting realistic weight loss goals and working with a dietitian who can personalize a plan for you and your needs is one way to improve your weight loss. Following a healthy lifestyle and diet can improve symptoms caused from lack of a thyroid.
