Intermittent Fasting for Psoriasis: Is It Safe and Can It Help?

You may already try to change or adjust your diet by eating or avoiding certain foods to reduce psoriasis attacks. But how would you like to focus on when you eat to improve your symptoms?

Intermittent fasting Diet is more focused on the time you eat that what you eat. It has become popular as a method to lose weight and increase metabolism. However, there is little evidence that fasting offers notable benefits to people with psoriasis, and practice may cause more harm than benefits.

We are told that some dietary adjustments improve the symptoms of psoriasis, but there is some research. In a 2017 U.S. national survey, People suffering from psoriasis reported that anti-inflammatory foods such as healthy vegetables and oils improve their skin. They also reported that the reduction of sugar, alcohol, morelle vegetables and gluten contributed to improving their skin.

Besides your medical treatment, you may want to change your diet or lifestyle to relieve the symptoms.

If you would like to learn more about intermittent fasting, here is a short description of the benefits and risks for people with psoriasis.

What is intermittent fasting?

There are so many ways of fasting intermittently. A common method is 16/8 when you limit your food to a few hours a day.

In this approach, you eat in a window of 8 hours each day, and quickly until the next cycle begins. For 16 hours of fasting, you will usually sleep. A lot of people prefer to continue fasting after sleep and skip breakfast and start their meal period later in the day.

Another method of limiting your calorie intake two days a week and eating the remaining days as usual. For instance, you can limit your calorie intake to 300 calories a day for two days a week. Or you can switch every two days between 300 calories a day and your normal eating habits.

The third method is 24-hour fasting when you stop eating for 24 full hours. This method is generally practiced during one or two days per week. It can lead to more harmful side effects such as tiredness, headaches, and reduced energy levels.

Before beginning any method of intermittent fasting, it is important to follow the advice of your physician or dietitian to find the right diet plan for you.


We have limited research on intermittent fasting and psoriasis. Little small observational research exists. Human studies of this subject are not clear either.

One observational study examined 108 patients suffering from mild to severe plate psoriasis. And they fasted in the month Ramajan. The researchers found a significant reduction in area and severity scores for psoriasis or PASI following fasting.

Another study The same researchers observed the effects of fasting among 37 people suffering from psoriatic arthritis. Their results have shown that short-term fasting improves patient activity scores.

But under a 2019 review on the effects of Ramajan fasting and other kinds of fasting on the health of the skin, the researchers found that the results lead to ambiguity or confusion in their suggested benefits.

Right now we have one 2018 review Nutritional strategies for observed psoriasis weight loss and a healthy lifestyle leads to a noticeable decrease in PASI scores in people with moderate to severe psoriasis. Low-calorie diets and periodic fasting have also been demonstrated to reduce the severity of psoriasis and other conditions in obese individuals.

Further research is needed to determine whether periodic fasting may improve the symptoms of psoriasis. However, following a healthy lifestyle and taking a low-calorie diet, if necessary, can help.


There is little evidence to suggest that intermittent fasting can improve the symptoms of psoriasis. Regular fasting may lead to harmful habits and hazardous side effects.

Certain possible side effects of fasting include:

  • eating disorders and disorganized eating, primarily excessive food intake on meal-free days.
  • Dizziness, confusion and dizziness when you work out during fasting.
  • severe hypoglycemia (low blood sugar) and other serious health issues for people taking diabetes drugs.
  • obesity as a result of skipping breakfast.
  • less energy levels.

A review of dietary guidelines for people with psoriasis and psoriatic arthritis resulted in the National Psoriasis Foundation recommending a low-calorie diet for obese people. Researchers found very little evidence that certain foods and diets may reduce symptoms in certain individuals. They also stressed the importance of continuous medical treatment rather than just in response to dietary changes.

Periodic fasting can be the most recent popular diet to lose weight. But there is a lack of scientific evidence to judge its effectiveness.

It can also present a risk to the health of people with certain complications, namely:

  • diabetes
  • pregnant/lactating women (breastfeeding)
  • Individuals with a history of eating disorders/eating disorders.


Further research is needed to enhance or reduce the impact of fasting on psoriasis.

Most studies about the benefits of intermittent fasting are only conducted on animals. There are only limited, small-scale studies which suggest possible improvements in psoriasis symptoms. They are particularly associated with low-calorie or short-term fasting diets.

Check with your doctor or dietitian for more information on how changes in your diet may help manage or reduce your psoriasis symptoms.
