In the realm of dietary plans, the ketogenic (keto) diet and the anti-inflammatory diet stand out as popular choices, each lauded for their potential health benefits. While both diets aim to improve overall well-being, they differ significantly in their approach, structure, and specific advantages. This article delves into a detailed comparison of these two dietary strategies, exploring their mechanisms, benefits, and practical implementation.
Understanding the Ketogenic Diet
The ketogenic diet is characterized by a high intake of fats, very low consumption of carbohydrates, and a moderate amount of protein. The primary goal of the keto diet is to induce a metabolic state called ketosis. Normally, the body uses glucose, derived from carbohydrates, as its primary energy source. However, when carbohydrate intake is drastically reduced, the body turns to fat for fuel. This process leads to the production of ketone bodies in the liver, which then become the alternative energy source.
How Ketosis Works
When the liver breaks down fats, it produces chemicals called ketones. When the level of ketones in the blood reaches the appropriate level, and the body relies on fat, or specifically ketone bodies, for energy, it enters a metabolic state called ketosis. The keto diet, in a sense, stresses the body initially, which sparks a protective response much like exercise does to muscles. As a result, it reduces inflammation, oxidative stress, and sensitivity within the nervous system- all of which can help with managing chronic pain.
Historical Context and Evolution
The ketogenic diet officially marked its 100th anniversary in 2021. In the 1920s, the keto diet was introduced as an alternative therapy to help children with epilepsy after doctors saw that mimicking the metabolism of fasting not only improved symptoms but also helped control seizures.
Variations of the Ketogenic Diet
The classic KD was designed in 1923 for the treatment of epilepsy by Dr. Russell Wilder at the Mayo Clinic. All KDs are a variation of the classic KD, the main difference being the macronutrient ratio: the Modified Ketogenic Diet (2:1-1:1), the Modified Atkins Diet (MAD; 1:1), and more recently the Medium-Chain Triglyceride (MCT) oil diet (1.9:1), Low Glycemic Index Treatment (LGIT) and Intermittent Fasting.

Potential Benefits of the Ketogenic Diet
- Weight Loss: The keto diet can be effective for short-term weight loss. By restricting carbohydrate intake, the body is forced to burn fat for energy, leading to a reduction in body fat stores.
- Improved Insulin Sensitivity: The keto diet has been shown to improve insulin sensitivity, which is beneficial for individuals with insulin resistance or type 2 diabetes.
- Seizure Control: The ketogenic diet was originally developed for the treatment of epilepsy in children who did not respond to medication.
- Reduced Inflammation: The keto diet may help reduce inflammation in the body. When your body is in ketosis, it is using fats for energy instead of sugars. Sugar happens to be inflammatory.
Potential Drawbacks and Considerations
- Nutrient Deficiencies: Eliminating grains, fruits, many vegetables, as well as other healthy foods from your diet depletes your body of the vitamins and minerals you need to stay in balance.
- The "Keto Flu": Shea first described how he felt after his body had switched into a state of ketosis.“[I initially] had a lot of gastrointestinal problems, [a] bit of stomach gurgling, bloating, [feeling] really, really lethargic. And I didn’t really want to do much, [it] felt like a headache as well. And that lasted for about four or five days,” he said. These symptoms are more commonly referred to as the “keto flu“.
- Digestive Issues: Dr. Guite, meanwhile, expressed concern about the health of the gut microbiome while on the keto diet. She said recent research has indicated that children on long-term ketogenic diets had lower levels of gut bacteria that protect the gut lining.
- Sustainability: On a more personal level, Shea also shared his struggles with strictly following the diet, especially in social settings.“[It] was very hard to do in the beginning. Because in the beginning, you just want a cake, cookies, bread, rice, anything. And then you have to realize that those are all things that you can’t really eat,” he said.
Exploring the Anti-Inflammatory Diet
Unlike keto, the anti-inflammatory diet focuses on reducing inflammation in the body. The anti-inflammatory diet is a proactive strategy for total wellbeing since it focuses on eating foods that reduce inflammation. This dietary approach emphasizes the consumption of foods known to combat inflammation while avoiding those that promote it.
Key Principles of the Anti-Inflammatory Diet
- Emphasis on Whole Foods: The anti-inflammatory diet prioritizes whole, unprocessed foods such as fruits, vegetables, whole grains, and lean proteins.
- Healthy Fats: Poly- and monounsaturated fats that come from foods such as fish, walnuts, and olive oil are best to help decrease inflammation, which is the root cause of joint pain.
- Limited Processed Foods: The diet restricts processed foods, refined sugars, and unhealthy fats, which are known to contribute to inflammation.
- Spices and Herbs: Spices like turmeric and ginger are incorporated for their potent anti-inflammatory properties.
Potential Benefits of the Anti-Inflammatory Diet
- Reduced Inflammation: The anti-inflammatory diet is designed to reduce inflammation, which is linked to chronic conditions like arthritis, cardiovascular disease, and even certain cancers.
- Improved Overall Health: By focusing on nutrient-rich foods, the anti-inflammatory diet supports overall health and well-being.
- Sustainable Long-Term Approach: Both diets reduce inflammation, but the anti-inflammatory diet is more sustainable long-term.
Potential Drawbacks and Considerations
- Requires Careful Planning: Implementing the anti-inflammatory diet effectively requires careful planning to ensure a balanced intake of nutrients.
- May Not Result in Rapid Weight Loss: While the anti-inflammatory diet can support weight management, it may not lead to rapid weight loss like the keto diet.

Scientific Evidence and Research Findings
Ketogenic Diet and Inflammation
Research suggests that the ketogenic diet may have anti-inflammatory effects. For example, a study published in Nature Communications found that a low-carbohydrate diet reduces inflammation in the brain. The researchers used a small molecule called 2-deoxyglucose, or 2DG, to block glucose metabolism and produce a ketogenic state in rats and controlled laboratory cell lines.
Mediterranean Diet and Psoriasis
MD is characterized by a high consumption of fruits, vegetables, and cereals; moderate consumption of fish, olive oil, nuts, and legumes; and low intake of poultry, eggs, and red meat. Recent studies have highlighted the positive effect of this eating pattern in many cardiometabolic and auto-inflammatory disorders possibly due to the reduction in oxidative stress and inflammation.
Ketogenic Diet and Psoriasis
The main characteristic of KD is the low content of carbohydrates (less than 30-50 g/day) along with an increase in protein and fat (75-80% kcal from fat, 5-10% kcal from carbohydrates, and 15-25% kcal from protein of the total daily energy consumption). This results in a metabolism switch to fat consumption as a main source of energy, leading to an increase in fatty acids and ketone bodies, which have anti-inflammatory properties by reducing IL-β and TNF-α plasma levels.
