Living with psoriasis is a multi-layered experience. Patients contend with the physical symptoms of constant discomfort related to the red, scaly patches on the skin, along with the emotional weight of feeling self-conscious about the lesions. The relentless itch and irritation can make even simple tasks feel overwhelming. While there are many treatments available, the side effects often feel to patients like trading one problem for another. This leaves many searching for alternatives that provide genuine relief without the extra hassle.
In 2021, researchers at Ghent University conducted a randomized controlled cross-over clinical trial Study, published at the EADV Spring Symposium, that introduced a new approach in the search for effective psoriasis management. Their findings sparked interest and hope, suggesting there may be alternative ways to address the symptoms of this condition.

About The Study: Objectives And Methodology
The study aimed to investigate whether the 5:2 diet, a form of modified intermittent fasting (MIF), could alleviate symptoms of psoriasis. Traditionally managed with medications, psoriasis the role of diet in treating psoriasis has been less explored.
Researchers sought to determine if the 5:2 diet could complement existing treatments while examining the potential link between gut health and psoriasis. The 5:2 diet involves eating normally five days a week and drastically reducing calorie intake to 500 calories on two non-consecutive days.
The study was conducted as a randomized controlled trial (RCT) involving 24 participants with mild to moderate psoriasis. These participants were randomly assigned to two groups: one followed the 5:2 diet for 12 weeks, while the other continued their typical eating habits without any changes. The control group allowed the researchers to assess the specific effects of the diet, comparing them to the normal progression of the condition.
Throughout the study, the researchers closely monitored changes in psoriasis symptoms using tools like the Psoriasis Area and Severity Index (PASI) and Body Surface Area (BSA), as well as tracking body weight and waist circumference.
The study also explored the gut-skin connection, hypothesizing that the diet might improve gut health, potentially leading to reduced inflammation and, consequently, less severe psoriasis symptoms. This innovative approach offers valuable insights into how diet could influence chronic skin conditions.
Key Findings of the Study
The study found that patients who followed the 5:2 diet experienced a significant reduction in the severity of their psoriasis symptoms. Specifically, they reported less scaling and thickening of the skin, with 30% of participants also noting a decrease in itching, which provided much-needed relief from one of the more uncomfortable aspects of the condition.
At the beginning of the study, objective measures like the Psoriasis Area and Severity Index (PASI) and Body Surface Area (BSA) showed no significant differences between the diet group and the control group. However, by the end of the 12 weeks, those on the 5:2 diet showed more improvement in these scores, indicating that the diet positively impacted their psoriasis over time.
In addition to improvements in skin symptoms, participants on the 5:2 diet also saw reductions in body weight and waist circumference. This suggests that the diet not only helped with psoriasis but also contributed to overall weight loss, which may be linked to the observed reduction in symptoms.
Significance of the Findings
The significance of the study's findings lies in the potential impact on how psoriasis can be managed. Here are the key points:
Non-Pharmaceutical Management
The findings suggest that the 5:2 diet could offer a simple, non-pharmaceutical approach to managing psoriasis symptoms, providing an alternative for patients who prefer to avoid long-term medication.
Empowerment for Patients
The potential to control psoriasis symptoms through diet is empowering for patients, offering them a proactive way to manage their condition, which often requires lifelong treatment.
Contribution to Gut-Skin Research
This study supports the growing body of research linking gut health to skin conditions, highlighting the potential role of dietary changes in improving skin health by influencing the gut microbiome.
Impact of Weight Loss on Psoriasis
The study provides new evidence that weight loss and dietary changes may positively affect psoriasis, suggesting that managing obesity could be a key factor in improving skin symptoms.
Potential for Widespread Use
With further validation from additional research, the 5:2 diet could be recommended as a natural and accessible strategy for managing mild psoriasis, complementing existing treatments.
Limitations of the Study
While the study's findings are promising, the small sample size limits the generalizability of the results, requiring confirmation in larger, more diverse populations. Additionally, the study only examined the short-term effects of the 5:2 diet over 12 weeks, leaving its long-term impact on psoriasis unclear. More research is needed to determine if the benefits can be sustained over time and assess potential long-term risks.
The study also focused on individuals with mild to moderate psoriasis, so it's uncertain whether the 5:2 diet would be effective for those with more severe forms of the condition. This underscores the need for further research to explore the diet's impact on a broader range of psoriasis severity to ensure the findings apply to a broader patient population.

Key Takeaways
- The 5:2 diet has shown potential as a tool for managing psoriasis, with some patients experiencing reduced scaling, skin thickening, and itching. These initial findings suggest that dietary changes could be an effective strategy for symptom control.
- While the results are promising, further research is necessary to fully understand the diet’s long-term impact and effectiveness across different severities of psoriasis. These findings introduce a promising new approach to managing the condition without relying solely on pharmaceuticals.
- With more supporting evidence, the 5:2 diet could become a key recommendation for those looking for a natural and accessible way to reduce psoriasis symptoms.
