New research in mice suggests that ketogenic diets with a very high fat content could actually worsen skin inflammation. The team now urges people with psoriasis to avoid such diets.
Ketogenic, or keto, diets are high in fats and low in carbohydrates.
People often use such diets for weight loss, as they stimulate the body to enter ketosis.
This is a state in which the body starts burning fat for energy rather than carbohydrates, as it naturally would.
Some studies suggest that keto diets may help manage the symptoms of type 2 diabetes and protect against cognitive decline, and doctors sometimes advise people with epilepsy to follow a keto diet to reduce the frequency of seizures.
