The effects of intermittent fasting on markers of health: A Narrative review

Abstract

Background: Intermittent fasting (IF) has gained significant popularity in recent years, both in medical and sports fields, primarily due to its potential improvements in various systems of the human body, including the metabolic, cardiovascular, and immune systems. Aim: This narrative review aims to explore the health effects of intermittent fasting (IF) in both healthy and unhealthy subjects, as well as mice. It aims to shed light on the diverse physiological mechanisms through which IF may influence health outcomes. Materials and Method: A comprehensive search for English-language manuscripts related to IF was conducted on PubMed and Google Scholar. The reviewed manuscripts focused on the effects of intermittent fasting on the immune system and lipid profiles. Results: The data analysis revealed that intermittent fasting had a positive impact on the mentioned indicators. The findings suggest that IF could be an effective strategy for achieving better overall health. Conclusion: Intermittent fasting appears to offer potential health benefits, showing positive effects on the immune system and lipid profiles. Further research is warranted to fully understand the mechanisms underlying these effects and to explore its suitability as a health intervention.
