What You'll Learn

Dr Gundry's diet philosophy
Dr. Steven Gundry is a former cardiac surgeon and physician with a 40-year career in medicine. His philosophy is a radical break from traditional dietary advice, offering a breakthrough for those who have struggled with their energy levels, weight, and health.
Gundry's diet philosophy centres on the belief that many plants contain harmful levels of lectins, a class of proteins that cause weight gain and chronic diseases. Lectins are found in legumes, grains, and nightshade vegetables like tomatoes, eggplants, and bell peppers. He advocates for a lectin-free diet, which has been criticised by some in the scientific community for lacking evidence and contradicting mainstream nutritional science.
Gundry's approach to nutrition is detailed in his book "The Plant Paradox: The Hidden Dangers in 'Healthy' Foods That Cause Disease and Weight Gain." The book emphasises the consumption of whole, nutritious sources of protein and fat while banning nightshades, beans, legumes, grains, and most dairy. He also promotes a low-carbohydrate diet, as outlined in his book "Unlocking the Keto Code," which includes goat and sheep dairy, grass-fed beef, shellfish, olive oil, and red wine.
Gundry's advice also includes increasing the intake of plants and nuts, reducing simple carbohydrates, and consuming fish and grass-fed meats. He suggests that plateauing on a diet is a sign of being on the right track and emphasises choosing micronutrient-rich, "calorie-scant" foods over simply “low-calorie” options. Additionally, he recommends avoiding artificial sweeteners and certain medications like antacids, statins, and drugs for high blood pressure, as they only mask health issues instead of addressing them.
Gundry's diet philosophy has been praised by some for its effectiveness in weight loss and improving health markers, but it has also faced criticism for contradicting established dietary recommendations and lacking scientific support.

Lectin-free diet
Dr Steven Gundry is a former cardiothoracic surgeon and the founder of the Center for Restorative Medicine in Palm Springs, California. He is also the author of several books, including *Dr Gundry's Diet Evolution: Turn Off the Genes That Are Killing You and Your Waistline*, and *The Plant Paradox*. In his books, Dr Gundry advises against the consumption of lectins, which are naturally occurring proteins found in all foods, especially plants.
According to Dr Gundry, lectins are responsible for numerous physical discomforts and may cause intestinal hyperpermeability, or leaky gut syndrome. Lectins may attach to the cells lining your intestines and can stay there for a long time, potentially causing an autoimmune response.
A lectin-free diet avoids grains, sugars, processed foods, all beans, lentils, legumes, some nuts and seeds, dairy containing the A1 protein, and specific vegetables, including tomatoes, squash, and bell peppers. Lectins tend to be highest in raw legumes, such as peas, beans, lentils, soybeans, and peanuts, and in whole grains such as wheat.
However, it is important to note that the lectin-free diet has been criticised by some experts. Robert H. Eckel, an endocrinologist and past president of the American Heart Association, argues that Dr Gundry's diet advice contradicts standard dietary recommendations. Harriet Hall of Science-Based Medicine has also noted that the evidence for the benefits of a lectin-free diet is anecdotal and meaningless, as there are no studies with control groups in the medical literature to support these claims. Additionally, lectin-free diets eliminate many foods that are recommended as part of a healthy, well-balanced diet, such as fruits, vegetables, whole grains, and nuts and seeds.
If you are considering starting a lectin-free diet, it is always a good idea to consult a healthcare professional or a registered dietitian to ensure that you are getting all the necessary nutrients and to determine if this diet is suitable for your individual needs.

The Plant Paradox diet
The diet plan cuts out or significantly reduces foods that contain high levels of lectins, such as wheat, beans, legumes, peanuts, soybeans, nightshade vegetables (like eggplants, peppers, potatoes, and tomatoes), traditional dairy products, grains (including wheat and rice), sugar, and whole grains. It is important to note that cooking methods can affect lectin levels, and proper cooking techniques, such as pressure cooking and fermenting, can reduce potential negative effects.
While some individuals, especially those with pre-existing digestive issues or autoimmune conditions, have reported positive results and weight loss with the Plant Paradox diet, critics argue that there is insufficient scientific evidence to support the idea that all lectin-containing plant foods are harmful. In fact, many lectin-containing foods are highly nutritious, and cooking methods can further reduce any potential negative effects.
Before starting any restrictive diet, it is always advisable to consult with a healthcare professional or registered dietitian to ensure it is safe and appropriate for your individual needs and health status.

Micronutrient-rich, calorie-scant foods
Dr Gundry's advice focuses on heart health and follows the conventional wisdom of Western diets, such as drinking a glass of red wine per day, increasing the intake of plants and nuts, reducing simple carbohydrates, and consuming fish and grass-fed meats.
Some examples of micronutrient-rich, calorie-scant foods include:
- Kale: a green, leafy vegetable rich in vitamins, minerals, fibre, antioxidants, and various bioactive compounds.
- Blueberries: a powerful source of antioxidants.
- Avocados: a great source of healthy monounsaturated fats, potassium, folate, and vitamin E.
- Oily fish, such as salmon and mackerel: high in omega-3 fatty acids, which are essential nutrients for the correct functioning of every cell in the body. They are also high in protein and B vitamins, and support heart health.
- Mushrooms: low in calories but nutrient-dense, containing antioxidants, fibre, and B vitamins.
- Pumpkin seeds: a good source of magnesium, zinc, and healthy fats. They promote heart health, prostate health, and sleep quality.
It is important to note that no single food can provide all the nutrients your body needs, so a varied diet with a wide variety of fresh foods is ideal.

Dr Gundry's advice focuses on heart health and follows the conventional wisdom of Western diets. This includes drinking a glass of red wine per day, increasing the intake of plants and nuts, reducing simple carbohydrates, and consuming fish and grass-fed meats.
When it comes to fats and oils, Dr Gundry recommends a variety of options, including:
- Olive oil: While olive oil may increase cholesterol levels, consuming a liter of olive oil a week will not lead to weight gain and may even help with weight loss.
- Coconut oil: Coconut oil is good, but it should be consumed in moderation as it is pure saturated fat.
- Grass-fed ghee: Dr Gundry recommends grass-fed ghee as it has a more balanced ratio of saturated to unsaturated fat and a superior omega profile, including high levels of Omega 3 fats.
- Macadamia nut oil: Macadamia nut oil is rich in monounsaturated fats and Omega 9s. It is also great for cooking.
- Red palm fruit oil: This oil is one of the approved oils in the Plant Paradox diet and can be difficult to find in stores.
In general, Dr Gundry encourages a diet with a wide variety of fats, as this will improve your microbiome's biodiversity. Additionally, he emphasizes the importance of avoiding fake fats, which can be harmful to heart health.
