Secrets of Popular Diets: Fasting Mimicking Diet (FMD) — Calories, Macros & the High-Protein Advantage for Fat Loss & Muscle

In this episode, Vanessa breaks down the fasting mimicking diet (FMD) — including the exact calories, macros, and protein intake used in the research — and compares it to higher-protein fat loss approaches like protein-sparing modified fasting (PSMF) days .

You'll learn what the science actually shows about fat loss, lean mass preservation, and autophagy , and why emerging human data suggests that energy restriction — not protein suppression — may be the primary driver of many fasting-related benefits.

This episode challenges the idea that protein and mTOR are "anti-longevity" and explores a more nuanced, evidence-based approach — especially for women focused on body recomposition, fat loss, and metabolic health .

🧠 In This Episode:

• The exact calories and macros of the fasting mimicking diet (FMD)

• What the 2017 FMD study actually showed

• Why lean mass loss can occur on low-protein approaches

• New 2025 human research on autophagy and protein intake

• Why energy deficit — not fasting frequency — drives fat loss

• What alternate-day fasting research shows about body composition

• The role of protein in preserving muscle during fat loss

• Why mTOR is not the enemy

• The high-protein advantage for fat loss and muscle retention
