Fitness expert claims alternating PSMF protocol broke 9 percent body fat plateau

What was said

"I got to 9% body fat, and the thing that actually moved the needle wasn't what I was doing 7 days per week. It was what I was doing 2 days per week, and it was surprisingly easy. It's a protocol called PSMF, and I use it as a metabolic shock to break through plateaus whenever I feel a little bit stuck."

The speaker describes using a two-day-per-week protein-sparing modified fast (PSMF) protocol to break through fat loss plateaus and reach 9% body fat, contradicting the conventional approach of sustained moderate caloric deficits. The protocol involves consuming only 800-1000 calories on two days weekly, consisting almost entirely of lean protein with minimal carbs and fat, followed by five normal eating days. He cites research showing alternate-day fasting approaches outperformed traditional time-restricted eating in meta-analysis of 24 randomized controlled trials.
