I’ll be sharing:
- Exactly how I structure PSMF days for myself, including my research based updates on the method
- How I base my approach on cutting-edge research, including the brand-new 2025 meta-analysis on protein intake and lean mass preservation during fat loss
- My personal results so far — how much weight I’ve lost since starting August 1, how it’s affecting my body composition, and what’s working best for me
- The latest studies on PSMF and refeed protocols: do refeeds really help with fat loss or just with muscle preservation and diet fatigue?
- Why pushing protein higher during a cut is “muscle insurance” and what the evidence says is the sweet spot for most women and men
If your goal is fat loss without losing muscle, this episode is your blueprint.
