Episode 486: Protein Sparing Modified Fasting

In this episode, we’re diving into the hot topic of protein sparing modified fasting (PSMF) and why short, strategic “3-day sprints” can be a powerful metabolic reset. Ali shares how these brief hypocaloric phases may help accelerate body fat loss while supporting anti-inflammatory processes and increasing autophagy, the body’s natural cellular cleanup system.

The literature consistently shows that most diets fail long term, with weight regain common within five years, and often much sooner with more aggressive interventions like GLP-1 medications or surgical approaches. In this conversation we explore who may benefit from protein sparing fasts, who should avoid them, where supplements fit in and how to implement this strategy. We also discuss research on autophagy.
