Intermittent Fasting 2025: Science-Backed Results vs. Social Media Hype

🥗 Introduction: The Fasting Frenzy

By 2025, intermittent fasting (IF) has evolved from a niche diet strategy into a global wellness phenomenon. Influencers, celebrities, and corporate wellness programs have popularized methods like 16:8, 5:2, and OMAD (One Meal a Day), each promising benefits ranging from weight loss to mental clarity. Yet, while clinical studies show compelling outcomes, social media hype often oversimplifies or exaggerates the science.

This deep-dive explores scientific research, cultural roots, risks, policy impacts, and market trends, separating evidence-backed health benefits from viral claims.
