Intermittent Fasting: Physiological Implications on Outcomes in Mice and Men

Area of Science:

• Nutrition Science
• Metabolic Health
• Aging Research

Background:

• Intermittent fasting (IF) is a dietary approach involving cycles of eating and fasting.
• IF is recognized for potential benefits against metabolic diseases, aging, and neurodegenerative conditions.
• Despite promising animal studies, IF's clinical feasibility and efficacy are debated.

Purpose of the Study:

• To review and compare IF outcomes and mechanisms in animal and human studies.
• To investigate tissue-specific changes induced by IF in preclinical models.
• To identify gaps in translating IF research from bench to bedside.

Main Methods:

• Comparative analysis of existing animal and human IF studies.
• Review of mechanisms underlying IF's effects.
• Discussion of limitations and inconsistencies in IF research.

Main Results:

• Animal studies report significant health benefits of IF.
• Clinical data on IF's feasibility and efficacy remain controversial.
• Systemic effects of IF necessitate tissue-specific investigations.

Conclusions:

• Further research is needed to validate IF's therapeutic potential in humans.
• Understanding tissue-specific responses is crucial for assessing IF's safety and efficacy.
• Bridging the gap between preclinical findings and clinical application is essential for IF translation.
