Ep 140: Should Women Fast? Talking fat loss, muscle growth & sustainability
Muscle Science for WomenShow Notes
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. CHAPTERS 00:13 Welcome 02:25 Ashleigh's 12-week cut and how it has actually felt 03:24 Extend the fat loss phase or start reversing out of it 05:47 Why Rachel treats the reverse diet as the part that matters most 07:29 Why hunger often goes up when you start eating more 09:47 Ashleigh's planned diet break, and never having reverse dieted with a coach 12:02 Coming back to structure after a diet break 13:31 Thinking about calories weekly and monthly instead of daily 15:48 Have a plan, without turning it into a numbers game 16:37 How the 36-hour fast came about 16:53 Rachel's fasting history and fasting as a tool in the toolbox 19:47 Resilience as Ashleigh's reason for short fasts 21:55 Rachel stopping at 24 hours, and changing the plan without calling it a failure 23:13 Ashleigh's 36 hours, and cycling the calories around the fasting day 27:41 Hunger during the fast, and hunger in a fat loss phase 30:22 Going to bed hungry, protecting sleep, and what Rachel eats before bed 33:26 Calorie cycling, autophagy, and who fasting may not suit 37:18 Getting enough protein inside a restricted eating window 39:17 PSMF explained, and what a PSMF day looks like in a week 44:23 Protein-forward resets, and why there is no one right way 46:15 Adherence as the deciding factor, and trying things for yourself 47:49 Wrap up, and where to send questions 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.

Can you be addicted to food? Rachel opens with the research she has been doing since the emotional eating episode. Then the ladies answer two listener questions: whether three, ten-minute blocks spread across a day can build strength, and how to adjust training through heavy cycles, low iron and deep fatigue.

How much fiber do you actually need, and can you overdo it? Rachel and Ashleigh sort the fiber claims that hold up from the ones that don't: where the 30 gram number came from, what happens when you jump from 10 grams to 40, whether fiber does anything for your hormones, and what to do about constipation on a GLP-1. They also talk about fiber supplements, resistant starch from cooked and cooled rice and potatoes, whether you should eat fiber before training, and more.

In this episode, Rachel and Ashleigh talk about recent struggles with comfort eating, sharing the reality that nearly EVERYONE has experienced at least once: eating in secret, or feeling shame and guilt over their food choices, and eating in a way that doesn't support your goals even when you know you don't really want to. Why do we sometimes eat compulsively even when we tell ourselves we shouldn't, or don't want to? Why do we feel so much shame around "guilty pleasure" eating? Rachel also shares where she has been over the past few months, including another heartbreak/grief cycle, a period of depression, starting a low dose antidepressant, and the body image feelings that come with regaining weight. In addition to sharing some very personal stories, they also offer a range of strategies and tactics for breaking habits that aren't serving you: things like urge surfing, planning, mindfulness and other therapies that can have a big impact. Some big lessons come out of this episode, including the fact that you are not alone in your struggles; externalizing your fears can make them less scary; and there is always work to be done (and why this is a good thing!)

Chapters 00:13 What this episode covers instead of fiber 03:44 Listener feedback on the Strong and Sculpted Shoulders program 05:48 Using food to take the edge off 08:36 Why the brain defaults to food under stress 10:16 Shame, guilt, and eating in secret 11:43 Meeting the pattern with compassion instead of shame 15:13 Getting back on track faster instead of never messing up 16:04 Urge surfing and pausing before you react 19:30 Interrupting the pattern and building new pathways 21:16 Setting up your environment and taking a portion instead of the whole bar 24:43 Working with a coach, structure, and tracking as data 26:11 Change takes time, Ashleigh on eating two dinners 28:25 Rachel on the past few months 30:18 Getting lean while depressed 32:41 Starting an antidepressant and what changed 36:27 Body image, postpartum, and pressure in the fitness industry 39:29 Externalizing it and asking for help 41:27 Stigma around antidepressants and weight loss drugs 45:43 What this podcast is for 47:00 The work is not done 48:55 Sponsor break, True Nutrition 51:42 Sign off Takeaways Both hosts say they eat to cope with stress, and both say that knowing the mechanism does not stop them doing it. Rachel frames the goal as getting back faster rather than never slipping, and says that interrupting the pattern even once starts building new pathways you can prove to yourself. Ashleigh's tool is putting time between the urge and the reaction, five or ten minutes, then deciding, so the choice is a made one either way. Rachel's portion approach for clients: take a serving instead of the whole bar, eat it somewhere else, pay attention to it, then step away and pick a different way to cope if the feeling is still there. Rachel says a low dose antidepressant has helped alongside therapy and her own work, and she is careful to say the medication did not cause the weight gain.
