Can a keto diet help with psoriasis?
The evidence is limited and mixed. Some people with psoriasis report improvement when they lose excess weight or reduce inflammatory, processed foods, but keto is not a proven treatment for psoriasis. Manage the condition with a dermatologist rather than relying on diet alone.
What We Can and Cannot Say About Keto and Psoriasis
Psoriasis is a chronic autoimmune-related skin condition that needs medical management. Diet is, at most, a supporting factor, and the research on keto specifically is not strong enough to make firm claims.
Where diet might play a role
Excess weight and obesity are associated with psoriasis severity in some studies, so weight loss can be helpful for certain people. Cutting back on ultra-processed foods, added sugar and alcohol is generally sensible and may reduce factors linked with inflammation. These benefits are not unique to keto.
Why keto is not a treatment
There is no reliable evidence that ketosis itself clears psoriasis, and responses vary. Some people feel better; others notice no change. Keto should never replace prescribed treatment. If you and your doctor think a weight-focused low-carb approach is worth trying, you can estimate your macros as a starting point.
Sensible expectations
A healthy weight and a whole-food diet may support overall skin and metabolic health, but they are complements to medical care, not substitutes. For related condition questions, you can explore the keto FAQ.
