For individuals grappling with chronic, elusive health conditions, the quest for answers can often be a long and frustrating journey. When conventional medicine falls short of providing definitive solutions, some individuals turn to anecdotal evidence and personal experimentation, which can occasionally lead to sustainable improvements. The Ray Peat diet, an unconventional approach to food and health, has garnered attention from those seeking alternative solutions to hormonal imbalances and metabolic issues.
Who Was Ray Peat?
Raymond "Ray" Peat, born in 1936 and passing away in November 2022 at the age of 86, was a PhD in chemistry who worked outside traditional academic settings. Based in Oregon, he dedicated his research to understanding the cell and developing theories about nutrition and the impact of specific foods. Peat's work often presented counterintuitive conclusions, challenging conventional nutritional wisdom.
Decoding the Ray Peat Diet: More Than Just a Food List
It's important to note that the Ray Peat diet isn't a rigidly defined eating plan with a specific food list. Instead, it's a philosophy centered around making "pro-metabolic" dietary changes to correct hormonal imbalances and improve metabolism. Erin Holley, a registered dietitian at the Ohio State University Wexner Medical Center, notes that even followers of the diet sometimes struggle to define it precisely.
Unlike many diets, Peat never published a book outlining specific eating guidelines, nor did he offer structured programs or lists of foods to eat or avoid. Much of the information available comes from secondary sources, such as wellness coaches and functional nutrition therapy practitioners, who may not always be reliable interpreters of Peat's ideas.
Despite the lack of a definitive guide, the Ray Peat diet has attracted a dedicated following, with many individuals reporting significant relief from various health issues through his unconventional recommendations. Benedicte Lerche, a biochemist, nutritional counselor, and thyroid specialist, is one such example. After struggling with a low thyroid disorder and finding limited help from conventional medicine, she consulted with Peat and found his theories instrumental in resolving her symptoms.

Core Principles of the Ray Peat Diet
While a specific food list is elusive, several core principles underpin the Ray Peat diet:
Prioritize Easily Digestible Sugars
The diet emphasizes the importance of glucose, or sugar, for fueling cellular function. Proponents believe that the liver needs sugar to activate thyroid hormones. However, rather than advocating for unrestricted consumption of sugar-heavy foods and drinks, the diet suggests prioritizing fruit and honey as sources of easily digestible sugars, as they also contain beneficial vitamins and minerals.
However, moderation is key, as excessive consumption of even natural sugars can have negative consequences.
Embrace the Right Kind of Fat
A central tenet of the Ray Peat diet revolves around the type of fat consumed, particularly for individuals with hypothyroid conditions. Polyunsaturated fats (PUFAs), commonly found in vegetable oils, nuts, seeds, and fatty fish, are often considered heart-healthy due to their omega-3 fatty acid content. However, the Ray Peat diet suggests that PUFAs can be detrimental to health by inhibiting thyroid function.
Followers of the diet also point to the omega-6 fatty acids in PUFAs, which can promote inflammation and vascular problems when consumed in excess. Additionally, they argue that PUFAs are unstable due to their low melting point and can easily oxidize, becoming rancid and toxic.

Instead, the Ray Peat diet often favors saturated fats from sources like coconut oil and pasture-raised animal products.
Moderate Protein Intake
While Peat is very pro-carb and pro-fats, he isn’t as big of a proponent of protein. Protein intake is moderate and should be at least 80 grams per day. If you are more active, this is preferably 100 grams. Muscle meats like lean poultry, beef, pork, veal, and organ meats (e.g., liver) are recommended to be minimised because of their iron, tryptophan, cysteine, and methionine contents.
Frequent Meals
Those on a Ray Peat Diet need to consume more frequently, as it is believed to increase the metabolic rate.
Red Light Therapy
Light therapy, particularly red light, is another component of the Ray Peat method. Red light is believed to act as an anti-stress mechanism, supporting longevity and reducing cellular deterioration. As a component of sunlight, red light can penetrate tissues and promote healing.
Foods to Include in the Ray Peat Diet
While there isn't a definitive list, the following foods are generally included in the Ray Peat Diet:

- Dairy products: Milk, cheese (especially full-fat varieties)
- Fruits: Ripe and easily digestible fruits like oranges, tangerines, peaches, cherries, and melons
- Fruit juice: Freshly squeezed orange juice is particularly emphasized for thyroid health.
- Honey: Raw honey is considered a beneficial sweetener.
- Coconut oil: Recommended in moderate amounts.
- Shellfish: Oysters, mussels, clams, and prawns are included for their mineral content.
- Gelatin: A source of protein.
- Liver: In small quantities.
- White sugar: Considered a safer alternative to other sweeteners besides honey.
- Carrots and Bamboo Shoots: Raw grated carrot salad with coconut oil
Foods to Avoid or Limit
The Ray Peat diet typically advises limiting or avoiding the following:
- Polyunsaturated fats (PUFAs): Found in vegetable oils (sunflower, safflower, canola, corn, soybean, cottonseed, peanut, hemp, flax, palm, sesame), nuts, seeds, fatty fish, margarine, and processed foods.
- Processed foods: Sodas with high fructose corn syrup, pre-prepared foods, and restaurant meals.
- Excessive muscle meats: Lean poultry, beef, pork, and veal are recommended to be minimized because of their iron, tryptophan, cysteine, and methionine contents.
- Certain additives: Carrageenan, carob bean gum, guar gum, xanthan gum, locust bean gum, agar agar, and thickeners like corn, potato, wheat, and rice starch.
- Citric acid: Especially synthetic citric acid found in many processed foods.
Potential Benefits of the Ray Peat Diet
Ray Peat's research focused on hormones and the effects of eating habits on hormonal balance. Although more research is needed to fully explore the short- and long-term effects of this eating routine, some potential benefits have been suggested:
- Improved thyroid function: Proponents believe the diet can positively impact thyroid hormones and insulin secretion.
- Increased energy levels: By providing the body with readily available energy from carbohydrates and fats, the diet aims to increase metabolic rate.
- Hormonal balance: The diet emphasizes foods that boost thyroid and sex hormones to optimize hormonal balance and energy levels.
Potential Downsides and Risks
It's crucial to consider the potential downsides and risks associated with the Ray Peat diet:
- High carbohydrate intake: The diet's emphasis on carbohydrates can prevent ketosis, potentially hindering weight loss efforts.
- Blood sugar fluctuations: Consuming high-sugar foods can lead to fluctuations in blood glucose levels, potentially increasing the risk of insulin resistance, diabetes, and related health issues.
- Potential health problems: A high-sugar diet has been linked to inflammation, heart disease, obesity, type 2 diabetes, increased mortality, mood swings, tiredness, increased hunger, cancer, and fatty liver.
Is the Ray Peat Diet Right for You?
The Ray Peat diet is a controversial approach to eating, and its principles often contradict conventional nutritional advice.
Before making any significant dietary changes, it's essential to consult with a healthcare professional, especially if you have underlying health conditions or thyroid issues. There are conventional treatments available for hypothyroid conditions that may not require such drastic dietary changes.
