A 400-calorie every-other-day diet for two months improved symptoms, airflow, and reduced oxidative stress and inflammation in overweight asthma patients.

“These were overweight asthma patients, and we put them on a really rigorous regimen where every other day, they only ate 400 calories. So, that's not something that can be maintained as a lifestyle because it's very hard to maintain your body weight with that. But in these overweight asthma patients, over two months, it had profound beneficial effects in improving their symptoms, their air flow in their lungs. My lab, we measured indicators of oxidative stress and inflammation in the blood, which went down not right away but between two and four weeks of initiating that every-other-day metabolic switching regimen.”
