Impact of intermittent fasting on health and disease processes

This comprehensive 2017 review examines the potential clinical benefits of fasting, drawing data from human and animal trials. The authors present a promising but clearly preliminary body of evidence supporting the clinical benefits of various forms of fasting. They note the evidence suggests fasting improves whole-body insulin sensitivity and may reduce risk of neurodegenerative disease and cancer, though additional research is required to determine whether fasting will lead to hard clinical outcomes such as diabetes remission or heart disease prevention.
