# How to Boost Thyroid Function: 10 Diet Tips That Work

By Dr. Benedicte Lerche · Nutrition

> Ten practical dietary changes that directly support thyroid function — from which fats to use, to why raw carrots and coffee belong in a thyroid-healthy diet.

## Can I Boost My Thyroid With Diet?

1\. Following [Dr. Ray Peat](/blog/who-is-dr-ray-peat)’s bioenergetic approach, avoid all polyunsaturated fats — meaning liquid oils, nuts, and seeds — as these strongly inhibit your thyroid function on many different levels.

2\. Use coconut oil and butter as your sources of fat. Saturated fats and especially coconut oil support your thyroid function.

## Why Is Protein Important for Your Thyroid?

3\. Get lots of protein from milk products, eggs, shellfish, and meat. Good quality protein is important for a healthy liver, and the liver is important for the activation of the inactive thyroid hormone T4 to the active hormone T3.

4\. Get good sugars from ripe fruits and fruit juices — orange juice is a great choice. You can increase your thyroid function by about 25% by supplying your body with good sugars.

## How Do Full Meals Support Your Metabolism?

5\. Combine your meals to include both protein, fats, and carbohydrates. When your body gets a full meal, the stress hormones are lowered and your metabolism is strengthened.

6\. Keep your blood sugar steady by having milk and fruit between meals. A steady blood sugar keeps your metabolism up.

## Which Fibers Should You Avoid?

7\. Avoid indigestible fibers including seeds, grains, and raw vegetables in general. These fibers can feed bacteria in the intestine and produce toxins.

8\. Eat one to two raw carrots per day to clean your intestine. Carrots are an exception to the advice in number 7 and should be used raw, due to the antimicrobial properties of the raw carrot fibers.

9\. Use lots of [coffee](/blog/thyroid-coffee) with milk and sugar throughout the day (unless intolerable). Coffee stimulates metabolism and contains magnesium and B-vitamins.

10\. Get sunlight every day. If there is no sunlight, use light therapy lamps to support your thyroid and hormonal balance.

All of these dietary changes are explained in depth in my book [How to Boost Metabolism with Food](/books/how-to-boost-metabolism-with-food) and my [Metabolic Food Mastery™](/courses/metabolic-food-mastery) course, along with practical meal guidance and food lists.
