The results showed that the mice that ate the diet, which typically includes various meat, fish, poultry and nonstarchy vegetables, had higher survival rates than mice who ate carb-heavy diets. The two senior researches believed this is tied to the keto diet-blocking inflammasomes, which induce inflammation in response to infections.
Inflammasomes can also induce harmful immune system responses in the host, triggering gamma delta T cells. These cells produce mucus in the lungs, aiding the body to expunge infectious agents via coughing them out through the airways. The study found that T gamma cells, which expand more rapidly in humans than in mice, resulted in lowered presence of the flu virus in mice who ate the keto diet.
