Have you ever wondered if you could accelerate fat loss with just a few high-protein, very low-calorie days each week? In this episode, Vanessa dives deep into the modern science of Protein-Sparing Modified Fasts (PSMF) and how intermittent high-protein fasting can help women lose fat, preserve lean muscle, and improve metabolic health.
Vanessa reviews the latest studies on:
- 1–3 PSMF days per week compared to daily dieting
- Alternate-day and 5:2 style intermittent fasting approaches with high protein
- How PSMF days stack up against water fasting and generic low-calorie diets
- Fat loss, lean mass retention, and insulin sensitivity outcomes in women
She also shares her personal PSMF experiment — one month of cycling three PSMF days per week — and reveals her results: fat loss, waist measurement changes, muscle preservation, and how it felt in real life.
If you’ve been curious about modern approaches to PSMF, how to implement them safely, and whether they truly outperform traditional dieting, this episode brings you the evidence and the personal perspective.
