Ep 140: Should Women Fast? Talking fat loss, muscle growth & sustainability

Ep 140: Should Women Fast? Talking fat loss, muscle growth & sustainability

Author: Ashleigh VanHouten & Rachel Gregory | Fitness, Strength Training, Wellness August 18, 2026 Duration: 50:29

Rachel and Ashleigh both ran a short fast in the same week, Ashleigh for 36 hours and Rachel for 24, and this conversation is what came out of it. They cover why they each wanted to do it, how Ashleigh cycled the calories from her fasting day across the rest of her week instead of erasing them, and where fasting sits as one tool among many rather than a rule. The first stretch is a coaching conversation about Ashleigh's 12-week cut, how to decide whether to extend a fat loss phase, and why Rachel treats the reverse diet as the part that matters most. Later on, Rachel walks through how she uses a protein sparing modified fast day inside a weekly calorie budget, and both hosts talk about who fasting may not suit.

TAKEAWAYS
• Rachel's approach to extending a fat loss phase is to commit two weeks at a time rather than another four, and to keep going only if sleep, hunger and energy are still holding up.
• Rachel says the reverse diet is more important than the end of the diet, because hunger usually goes up as food increases, so the first two to three weeks are where the structure has to hold.
• Ashleigh fasted 36 hours and Rachel stopped at 24 because she was subbing for a football game that night and fighting a cold, which both hosts framed as changing the plan for a reason rather than failing it. Ashleigh, already in a deficit, redistributed the fasting day's calories across the rest of the week rather than erasing them, eating more in the days before and after.
• Rachel's PSMF day is roughly 0.8 to 1 gram of protein per pound of body weight with the rest filled by fiber and fat to around 1,000 calories, usually placed on a rest day, with the remaining calories spread over the other six days.
• Both hosts hedged the whole topic: fasting is a tool with benefits and drawbacks, it may not suit someone with a history of restrictive or disordered eating, someone pregnant or breastfeeding, or someone whose focus is building muscle, and nobody has to do it.
