Can Diet Affect Energy Levels?
According to Dr. Ray Peat, the gap between the body's resources and the demands placed on it from the environment creates disease. Thus harmful degenerative processes occur instead of repair and healing when there is a lack of cellular energy production. My diet recommendations support the energy production systems of the body, meaning thyroid function and metabolism. My diet recommendations are based on the revolutionary research of Dr. Ray Peat, who for more than 40 years researched the interplay between thyroid function and foods.
What Is The Best Thyroid Supporting Diet Plan?
My thyroid supportive diet teaches you:
Why sugar is necessary for a healthy metabolism.
What types of carbohydrates and sugars are best for thyroid function.
What oils directly harm your body's thyroid function.
What types of fats are supportive of cellular energy production.
How much protein your body needs in order to keep the liver healthy.
What types of protein are best for your metabolism.
How to combine food to optimise and stabilise your blood sugar.
What types of supplements are helpful in an energy supportive lifestyle.
My diet guides help you implement my thyroid supportive diet into your daily routine. They include meal examples and protein and calcium guides that teach you how to get enough of these anti-inflammatory nutrients into your daily diet. You can find all of this in my book How to Boost Metabolism with Food and my Metabolic Nutrition Mastery course.
Are There Foods To Avoid With Hypothyroidism?
The western diet and many health diets contain foods that directly suppress thyroid function. So if you are not using a special thyroid supporting diet, you are most likely getting many foods and substances that directly inhibit your thyroid function and cellular energy production. In my Metabolic Nutrition Mastery course you can learn about what foods and substances suppress your thyroid function. My approach to treating hypothyroidism is always to start out with a thyroid supporting diet, before using thyroid medication.
What Is The Ray Peat Thyroid Diet?
My thyroid promoting diet advice is based on the research of Dr. Ray Peat, an American biologist who for more than 40 years researched the interaction between nutrition, hormones, and health. I have used Dr. Ray Peat's thyroid promoting diet concepts in my own hypothyroid recovery. You can sign up to my mailing list and get my health story, where you can learn how I used Dr. Ray Peat's diet and health principles to overcome hypothyroidism and hormonal imbalances.
Can You Heal Hypothyroidism With Diet?
You can significantly increase your metabolism by using the right diet principles. In order to have a good thyroid function, you need a high-quality diet each day. For optimal production of thyroid hormones T4 and T3, your body needs enough high-quality protein, fats, and carbohydrates daily. In addition, special anti-microbial fibre-rich foods and certain vitamins and minerals are essential for a healthy metabolism and hormonal balance.
My diet advice is based on the research of Dr. Ray Peat. This diet is not just another quick fix — instead, it is built on a deep understanding of how the body works on the biochemical level. The main principle is to provide the cells of your body with the best food sources for producing energy.
What Fats Are Good For Thyroid?
An important principle of a thyroid supporting diet is to use the right fats. On a normal western diet, people are getting oils that powerfully suppress thyroid function on every level — including the production of the thyroid hormones in the thyroid gland, transport of the thyroid hormones in the blood, as well as the cell's response to the active thyroid hormone T3. Therefore my thyroid supporting diet includes fats that support thyroid function and excludes oils that suppress metabolism. My book How to Boost Metabolism with Food goes into detail about the different kinds of fats and oils and how they affect thyroid function.
What Is The Connection Between Liver And Thyroid Function?
The liver has many important functions in controlling thyroid function on the cellular level. Without good liver function, your production of the active thyroid hormone T3 is not sufficient. The liver controls most of the conversion of the inactive thyroid hormone T4 to the active thyroid hormone T3, and good liver function requires a large amount of high-quality protein as well as good sugars and carbohydrates to function optimally.
High-quality protein can come from certain dairy products, eggs, and selected meats. Healthy carbohydrates come mainly from low-starch fruit and vegetables. A healthy liver function also requires enough of all the B-vitamins as well as selenium, so it is important to focus on getting enough of these vitamins and minerals through your diet. My Metabolic Nutrition Mastery course goes into detail about how to support liver function with foods and supplements.
What Is The Best Hypothyroidism Diet?
My book How to Boost Metabolism with Food and my Metabolic Nutrition Mastery course go through all my diet and health principles for treating hypothyroidism. You will get a detailed description of my diet principles, with biochemical explanations for all my recommendations, as well as other important health and lifestyle information for improving thyroid function and hormonal balance.
If you are completely new to Dr. Ray Peat's health method, you may find some of the recommendations surprising, as my thyroid diet goes against many popular health guidelines. I strongly suggest starting with the full programme so you have the biochemical context behind each recommendation.
My Metabolic Nutrition Mastery course also helps you implement my thyroid supporting diet principles into your daily routine, with suggestions for breakfast, lunch, dinner, and between meals for supporting your thyroid function and hormonal balance.
Frequently Asked Questions
Can diet really affect thyroid function and energy levels?
Yes — according to Dr. Ray Peat, whose research my approach is based on, the gap between the body's energy resources and the demands placed on it creates disease. When cellular energy production is insufficient, harmful degenerative processes occur instead of repair and healing. Diet is one of the most powerful tools for supporting the energy production systems of the body, which includes thyroid function and metabolism.
What foods should I avoid with hypothyroidism?
The most important foods to avoid are those that directly suppress thyroid function — primarily polyunsaturated fats found in liquid vegetable oils, nuts, and seeds. The western diet and many popular health diets are full of these. Indigestible fibres from grains and most raw vegetables can also feed intestinal bacteria and increase endotoxin production, which suppresses thyroid function. I cover the full list in my Metabolic Nutrition Mastery course.
What fats are good for thyroid health?
Saturated fats — particularly butter and coconut oil — support thyroid function and do not interfere with thyroid hormone production, transport, or cellular response. Polyunsaturated fats from vegetable oils, nuts, and seeds do the opposite: they suppress thyroid function at every level. Replacing liquid oils with butter and coconut oil is one of the single most impactful dietary changes you can make for thyroid health.
Why is liver health so important for thyroid function?
The liver controls most of the conversion of inactive T4 into active T3 — the thyroid hormone that directly drives cellular energy production. Good liver function requires adequate high-quality protein, B-vitamins, selenium, and good sugars from low-starch fruits. Without these, T3 production is impaired regardless of how well the thyroid gland itself is functioning. Supporting the liver through diet is therefore an essential part of treating hypothyroidism.
How is the Ray Peat thyroid diet different from other diets?
The pro-metabolic approach based on Dr. Ray Peat's research goes against many popular health guidelines — it recommends sugar from ripe fruit and juice, coffee with milk and sugar, dairy, saturated fats, and the avoidance of many foods considered "healthy" such as vegetable oils and raw leafy greens. These recommendations are grounded in over 40 years of biochemical research on how food interacts with hormones and thyroid function. I used these principles myself to overcome hypothyroidism and hormonal imbalance, and I explain the biochemistry behind each recommendation in my How to Boost Metabolism with Food book.
