Psoriasis is an inflammatory disease of the epidermis, affecting 2-3% of the world's population. It is triggered by genetic, environmental, and nutritional factors. Studies have shown that obesity is a common factor in many patients with psoriasis, and weight loss interventions have been shown to improve the condition. The ketogenic diet, a popular weight-loss method, has been studied as a potential treatment for psoriasis. While some sources suggest that certain ketogenic diets may exacerbate psoriasis, others have found that a ketogenic diet can improve psoriasis symptoms and reduce inflammation.

What You'll Learn
Ketogenic diets and weight loss
The ketogenic diet has been shown to be an effective strategy for weight loss. This is a nutritional regimen that involves a reduction in carbohydrates and a relative increase in protein and fat intake. By depriving the body of glucose, the main energy source for cells, the body begins to produce an alternative fuel called ketones from stored fat. This state is known as ketosis, and it can be challenging to achieve and maintain.
The keto diet has gained popularity due to its promise of rapid weight loss. This is achieved through glycogen depletion and water loss. However, long-term fat loss depends on sustained caloric deficits and metabolic adaptation. The high-fat content of the diet may also contribute to weight loss by decreasing food cravings and reducing appetite-stimulating hormones. Additionally, ketone bodies may play a direct role in reducing hunger.
Despite its effectiveness for weight loss, the keto diet has some potential drawbacks. It can be difficult to adhere to due to its restrictive nature, and individuals may experience nutrient deficiencies if they do not carefully plan their meals. Common symptoms of low blood sugar, a potential side effect of the diet, include weakness, shaking, sweating, a fast heartbeat, and dizziness. The keto diet has also been linked to an increased risk of heart disease due to its high saturated fat content and lack of fibre. Furthermore, rapid weight loss on the keto diet may lead to muscle loss, which can negatively impact athletic performance.
While the keto diet may be beneficial for weight loss in the short term, it is important to consider adopting healthier eating habits for sustainable weight management. Additionally, combining the keto diet with other dietary regimens, such as intermittent fasting, can provide a more balanced approach and help maintain nutrient intake.

Ketogenic diets and inflammation
Psoriasis is a chronic inflammatory disease that affects approximately 2–3% of the world's population. It is associated with obesity, as excess adipose tissue causes a systemic inflammatory state. Therefore, weight reduction is a strategy to combat this pro-inflammatory condition.
The ketogenic diet is a nutritional regimen characterized by a reduction in carbohydrates and a relative increase in protein and fat. This diet induces a switch to ketone metabolism, lowering blood glucose and increasing blood ketones and mitochondrial function.
Several studies have shown that a low-calorie ketogenic diet can be a successful strategy to improve psoriasis-related dysmetabolism and correct the metabolic and inflammatory status. A 22-week study found that a combined Mediterranean-ketogenic diet program resulted in a significant reduction in weight, BMI, waist circumference, total fat mass, and visceral fat. After the ketogenic diet, patients displayed a significant reduction in the Psoriasis Area and Severity Index (PASI) and the Disease Activity Index of Psoriatic Arthritis (DAPSA).
The ketogenic diet's impact on inflammation is related to three main factors: insulin reduction, BHB synthesis, and glucagon increase. Insulin reduction leads to weight loss, which has anti-inflammatory effects. Additionally, the ketogenic diet may improve insulin sensitivity, reducing the production of pro-inflammatory cytokines such as TNF-α, IL-1b, and IL-6.
In summary, the ketogenic diet appears to be a promising strategy to manage psoriasis by reducing inflammation and improving metabolic markers. However, further large-scale studies are needed to confirm these findings and establish the diet's efficacy in a real-world setting.

Ketogenic diets and nutrition
Ketogenic diets have become an extremely popular way of achieving weight loss, but their impact on psoriasis is still unclear. Some sources suggest that certain keto diets may worsen psoriasis symptoms, while others claim that a ketogenic diet can help reduce them.
A study published in the Journal of Investigative Dermatology found that certain fats in the keto diet, particularly medium-chain triglycerides (MCTs), can exacerbate psoriasis. MCTs are found in coconut oil and are often used in cooking. However, the same study found that well-balanced ketogenic diets limited to long-chain triglycerides (LCTs) such as olive oil, soybean oil, avocado, and meats, did not worsen skin inflammation.
Ketogenic diets are characterized by a reduction in carbohydrates and a relative increase in protein and fat. This dietary change induces a switch to ketone metabolism, reducing blood glucose and increasing blood ketones and mitochondrial function. The ketogenic diet has been shown to have therapeutic potential in other inflammatory diseases, such as diabetes, and has been associated with weight loss, which can also help reduce psoriasis symptoms.
Several studies have found that a ketogenic diet can improve psoriasis-related dysmetabolism and reduce psoriasis symptoms. One study showed that a 22-week Mediterranean-ketogenic diet program led to beneficial results in disease activity and pro-inflammatory markers, with most benefits attributed to the ketogenic element. Another study of 30 psoriasis patients found that a ketogenic nutritional regimen improved clinical parameters, metabolic profiles, and inflammatory states.
While the ketogenic diet may offer potential benefits for psoriasis patients, it is important to note that individual food sensitivities can also trigger psoriasis flares. A personalized, balanced eating plan focused on avoiding trigger foods may be more effective for some individuals.

Ketogenic diets and obesity
Obesity is a significant worldwide health hazard, contributing to adult mortality rates as high as 2.8 million per year. It is closely linked to numerous chronic diseases, including diabetes, hypertension, and heart disease. Implementing tailored diet regimens for weight reduction can help tackle the obesity epidemic.
The ketogenic diet is a nutritional regimen characterized by a reduction in carbohydrates and a relative increase in protein and fat. The fat-to-carbohydrate ratio is typically 5:1. This diet induces a switch to ketone metabolism, reducing blood glucose and increasing blood ketones and mitochondrial function.
Several studies have shown that the ketogenic diet is quite effective in reducing body weight and improving weight-related risk factors for various chronic diseases. For example, a study of 83 obese patients with high glucose and cholesterol levels showed significant decreases in weight, body mass index, total cholesterol, and LDL cholesterol after 24 weeks on the ketogenic diet. Another study of 30 psoriasis patients on a ketogenic diet for four weeks showed improvements in clinical parameters, metabolic profiles, and inflammatory states.
The ketogenic diet has also been shown to be beneficial when combined with other diets. A 22-week combined Mediterranean-ketogenic diet program for patients with psoriasis and psoriatic arthritis led to beneficial results in disease activity and pro-inflammatory markers.
In summary, the ketogenic diet can be an effective tool for weight management and improving related health issues. However, more in-depth studies are needed to fully understand its safety and physiological effects on obese individuals.

Ketogenic diets and psoriatic arthritis
The ketogenic diet has been shown to have therapeutic potential in managing various diseases, and its effects on psoriasis and psoriatic arthritis have been explored in several studies.
Psoriasis is a chronic inflammatory disease affecting 2-3% of the global population. It is associated with obesity, as excess adipose tissue causes systemic inflammation. Weight loss interventions have been shown to improve psoriasis, and the ketogenic diet is a nutritional regimen that facilitates weight loss by reducing carbohydrates and increasing protein and fat intake. This dietary approach induces a switch to ketone metabolism, lowering blood glucose and increasing blood ketones and mitochondrial function.
A 2024 randomised crossover trial evaluated the effectiveness of a Mediterranean diet versus a Ketogenic diet in patients with psoriasis and psoriatic arthritis. The study found that both diets resulted in significant reductions in weight, BMI, waist circumference, total fat mass, and visceral fat. Notably, the ketogenic diet led to a significant reduction in the Psoriasis Area and Severity Index (PASI) and the Disease Activity Index of Psoriatic Arthritis (DAPSA).
Another study, a 22-week randomised, open-label, controlled crossover trial, divided 16 patients into two groups: one following a ketogenic diet and the other a Mediterranean diet for 8 weeks, followed by a switch after a 6-week washout period. The ketogenic group reported substantial decreases in interleukin (IL)-6, IL-23, DAPSA scores, and PASI scores. These findings suggest that the ketogenic diet can effectively improve disease activity in psoriatic arthritis.
A 9-week very low-calorie ketogenic diet intervention among overweight patients with psoriatic arthritis resulted in improvements in skin and joint disease activity, lipid profile, and significant weight loss. This diet was well-tolerated and demonstrated the potential of the ketogenic approach in managing psoriatic arthritis.
In conclusion, the ketogenic diet has shown promising results in improving disease activity and reducing inflammation in patients with psoriatic arthritis. It can be a valuable adjunct treatment to conventional pharmacological therapy, and further large-scale studies are needed to confirm these beneficial effects.
