24 Vitamin D, Perimenopause and Muscle: The Deficiency Most Trained Women Don't Know They Have
Body by DesignShow Notes
You’re putting in the work, but your body response isn't delivering the return on effort you expect. It’s a strategy gap many women over 40 face, often linked to an overlooked deficiency that impacts everything from muscle function to hormonal balance and perimenopause symptoms.
This isn't about a lack of sunshine or a simple fix. It’s about understanding a critical nutrient that, when deficient, can completely alter how your body responds to training and nutrition, leaving you guessing why your consistent efforts aren't paying off.
Lou Driver cuts through the noise to explain why this particular deficiency is so common in trained women, even those who spend time outdoors. She reveals the subtle symptoms you might be missing and how correcting this imbalance is key to proper calibration.
Tune in to stop guessing and truly understand what your body is telling you about this vital deficiency.

You want the midlife makeover, so you went all in on a diet. And you’re not seeing what you expected. One diet was never going to do it. The body you want is built across multiple phases over a couple of years, and the diet is only one of them, usually the smallest. This episode is the honest version nobody sells, for women over 40 who are serious about a real transformation.
You’re intelligent. You’re independent. You work everything out, your career, your business, your household, the problems no one else can solve. So you’ve decided you can work out your body too.
Two narratives are shouting on your feed: every perimenopausal woman must be on HRT, and menopausal women can’t lose fat in a deficit. Both are wrong. This episode is the nuance nobody wants, why perimenopause revealed your symptoms rather than caused them, and why fixing the foundations first means most women need far less than they’re told.
Marlene asked for this one before her holiday, so here it is.
This is the episode nobody in the industry talks about. Not more protein, not progressive overload. Who you have to become to have the body and health you want. Your body is a receipt, the lagging result of who you’ve been being, and you can’t get the body you want inside the identity of who you are now. For women over 40 ready to do the real work.
