Key Takeaways

  • You can burn fat without losing muscle by keeping protein high and calories low.
  • Autophagy occurs from calorie restriction — not protein restriction.
  • Ketones created during PSMF provide mental clarity, calm, and focus.
  • Strategic refeeds help lock in fat loss and prevent rebound weight gain.
  • When combined with strength training, PSMF becomes a powerful metabolic reset tool.
