To the Issue of Intermittent Fasting Diet Effect on Human Body

The article raises the issue of intermittent fasting (IF) effect on human health, including patients with comorbidity. The aims of the paper are to study, investigate and summarize the results of the clinical experimental work dedicated to IF over the past fifteen years, as of 2005. The author evaluates a “risk–benefit” ratio of IF; its effect on nutrition restrictions linked with religious fasting; IF exposure on the structure and composition of microbiota of intestinal tract. Despite numerous papers dedicated to experiments held on rodents, the issue under discussion is yet insufficiently studied and needs further research.
