The Gundry Diet, developed by Dr. Steven Gundry, is a unique approach to health and wellness that focuses on optimizing gut health and reducing inflammation in the body. Dr. Gundry, a renowned heart surgeon turned nutritionist, believes that many chronic diseases and health issues can be attributed to a leaky gut and the consumption of certain foods that are harmful to our bodies.

The Basics of the Gundry Diet

The Gundry Diet is centered around the concept of lectins, which are a type of protein found in many plant-based foods. According to Dr. Gundry, lectins can cause inflammation and damage to the gut lining, leading to a variety of health problems. The diet aims to eliminate or minimize the consumption of lectin-rich foods to promote better gut health and overall well-being.

Here are the key principles of the Gundry Diet:

  • Avoidance of lectin-rich foods: The diet recommends avoiding or minimizing the consumption of foods high in lectins, such as grains, legumes, nightshade vegetables, and certain fruits.
  • Focus on low-lectin alternatives: Instead of lectin-rich foods, the Gundry Diet encourages the consumption of low-lectin alternatives, including leafy greens, cruciferous vegetables, pasture-raised meats, wild-caught fish, and healthy fats.
  • Emphasis on gut health: The diet emphasizes the importance of maintaining a healthy gut microbiome by consuming probiotic-rich foods, such as fermented vegetables and yogurt, and taking probiotic supplements.
  • Intermittent fasting: Dr. Gundry recommends incorporating intermittent fasting into the diet, which involves restricting the eating window to a specific period of time each day.
  • Supplementation: The Gundry Diet suggests the use of certain supplements, such as polyphenols and prebiotics, to support gut health and reduce inflammation.

The Science Behind the Gundry Diet

While the Gundry Diet has gained popularity, it is important to examine the scientific evidence behind its principles. The concept of lectins and their potential negative effects on health is supported by some studies. Lectins have been shown to disrupt the gut barrier and contribute to inflammation in animal studies. However, more research is needed to fully understand the impact of lectins on human health.

Additionally, the Gundry Diet’s emphasis on gut health aligns with emerging research on the gut microbiome and its role in overall well-being. The gut microbiome, which consists of trillions of microorganisms, plays a crucial role in digestion, immune function, and even mental health. Maintaining a diverse and balanced gut microbiome is essential for optimal health.

Intermittent fasting, another key component of the Gundry Diet, has been studied for its potential health benefits. Research suggests that intermittent fasting may improve insulin sensitivity, promote weight loss, and reduce inflammation. However, it is important to note that intermittent fasting may not be suitable for everyone, and individual needs and preferences should be taken into account.

Potential Benefits of the Gundry Diet

The Gundry Diet claims to offer a range of health benefits, including weight loss, improved digestion, increased energy levels, and reduced inflammation. While individual results may vary, there is some evidence to support these claims.

Weight loss: By eliminating or reducing high-lectin foods and focusing on nutrient-dense alternatives, the Gundry Diet may help individuals achieve weight loss. Additionally, intermittent fasting, which is a part of the diet, has been shown to promote weight loss and improve metabolic health.

Improved digestion: The Gundry Diet’s emphasis on gut health and the consumption of probiotic-rich foods may help improve digestion and alleviate symptoms of digestive disorders, such as bloating, gas, and constipation.

Increased energy levels: By eliminating foods that may cause inflammation and disrupt gut health, the Gundry Diet may help individuals experience increased energy levels and improved overall well-being.

Reduced inflammation: Inflammation is believed to be a root cause of many chronic diseases. The Gundry Diet’s focus on reducing lectin consumption and promoting gut health may help reduce inflammation in the body.

Potential Drawbacks and Considerations

While the Gundry Diet offers potential benefits, it is important to consider some potential drawbacks and limitations:

  • Restrictive nature: The Gundry Diet can be quite restrictive, as it eliminates or limits many common foods, including grains, legumes, and certain fruits and vegetables. This may make it challenging for some individuals to adhere to the diet long-term.
  • Limited scientific evidence: While there is some scientific evidence to support the principles of the Gundry Diet, more research is needed to fully understand its effectiveness and long-term impact on health.
  • Individual variability: Each person’s nutritional needs and tolerances are unique. While lectins may cause issues for some individuals, others may tolerate them well. It is important to listen to your body and make dietary choices that work best for you.
  • Cost and accessibility: The Gundry Diet may require the purchase of specific supplements and specialty foods, which can be costly and may not be readily available to everyone.


The Gundry Diet, developed by Dr. Steven Gundry, offers a unique approach to health and wellness by focusing on gut health and reducing inflammation. While the diet has gained popularity and offers potential benefits, it is important to consider the limitations and individual variability when deciding whether to adopt this dietary approach.

By understanding the science behind the Gundry Diet and considering its potential benefits and drawbacks, individuals can make informed decisions about their dietary choices and overall health. It is always recommended to consult with a healthcare professional or registered dietitian before making significant changes to your diet.
