A Biochemical View on Intermittent Fasting's Effects on Human Physiology-Not Always a Beneficial Strategy.

Area of Science:

• Nutrition Science
• Metabolic Health
• Dietary Interventions

Background:

• Intermittent fasting (IF) is a popular dietary approach with potential health benefits.
• Evidence links IF to improved insulin sensitivity, reduced inflammation, and weight management.
• IF may play a role in managing obesity-related conditions like type 2 diabetes and fatty liver disease.

Purpose of the Study:

• To review the evidence for intermittent fasting's health benefits and therapeutic potential.
• To explore the mechanisms underlying IF's effects, including metabolic switching and AMPK activation.
• To discuss the variability in IF response and the need for personalized protocols.

Main Methods:

• Systematic review of preclinical and clinical studies on intermittent fasting.
• Analysis of mechanistic pathways involved in IF's metabolic effects.
• Evaluation of IF's impact on various health conditions and diseases.

Main Results:

• IF demonstrates potential in improving metabolic health markers and aiding weight loss.
• Mechanisms include metabolic switching and activation of adenosine monophosphate-activated protein kinase (AMPK).
• Responses to IF vary significantly among individuals, influenced by health status and diet.

Conclusions:

• Intermittent fasting holds promise as a disease-modifying intervention.
• Personalized implementation based on patient characteristics is essential for optimal outcomes.
• Future research should focus on identifying ideal IF protocols for different conditions.
