What if the reason you feel like garbage at 3PM every Tuesday isn't your coffee intake or your sleep schedule, but literally just... where you are in your cycle?
Okay, so I'll be honest - this isn't my usual genre. I'm way more likely to be listening to hard sci-fi or something about distributed systems than a book about hormones. But my friend Amanda kept texting me about it, and I was curious about the biohacking angle. Plus, 10 hours is basically a week of commutes, so I figured why not.
The Engineer Brain Meets Hormonal Cycles
Here's what got me: Vitti basically treats the menstrual cycle like a system with four distinct phases, each with different optimal inputs and outputs. As someone who literally debugs systems for a living, this framework clicked for me in a way that vague "listen to your body" advice never has. She breaks it down into follicular, ovulatory, luteal, and menstrual phases - and maps out what foods, exercises, and even work tasks are supposedly optimized for each one.
Is it backed by the kind of rigorous peer-reviewed research I'd want? Meh. She cites studies, but some of the claims feel more anecdotal than scientific. But here's the thing - the basic premise that women's bodies operate on a roughly 28-day cycle rather than a 24-hour one? That part actually makes sense. And the fact that most productivity advice is based on research done primarily on men? Also true, and kind of infuriating when you think about it.
The ROI on this audiobook is honestly pretty good if you're someone who's ever wondered why your energy levels are so inconsistent month to month. Even if you take the specific recommendations with a grain of salt, the framework itself is useful.
Vitti Narrating Her Own Work
So Vitti narrates this herself, and it's... fine? She's clearly passionate about the material, which helps when you're listening at 6AM surrounded by other commuters who look equally dead inside. Her enthusiasm is genuine and kind of infectious. But - and this is a real but - her pacing is on the slower side. I bumped it up to 1.5x pretty quickly and even considered going to 1.75x in some sections.
The production quality is clean, no weird audio issues. There's apparently a PDF that comes with it for the meal plans and charts, which... yeah, you're gonna need that. Some sections are basically her reading lists of foods and exercises, and that does NOT translate well to audio. I found myself zoning out during those parts. Could've been a blog post. (Actually, a lot of this could've been a blog post, but that's true of like 80% of self-help books.)
Who Should Listen (And Who Should Skip)
Perfect for: train, gym, walks. Skip for: deep work - there are sections where you'll want to take notes or reference that PDF.
If you're someone who's been on hormonal birth control for years and never really thought about your natural cycle, this might genuinely shift how you think about things. If you're already deep into cycle syncing and have read WomanCode, you'll probably find this repetitive - skip it.
I finished this in about 5 commutes, and I've actually started loosely tracking my cycle phases against my calendar. Not in a rigid way, but more like... okay, maybe I shouldn't schedule that big presentation during my luteal phase when I historically feel like a trash goblin. Is that placebo? Maybe. But also, who cares if it helps?
The science doesn't hold up as rigorously as I'd like - I wanted more citations, more data, less "I've seen this in my practice." But as a framework for thinking about your body differently? It's worth the listen. Outliers had me thinking differently about success patterns, and this does something similar for understanding biological patterns. Just maybe grab the physical book too if you actually want to implement the meal plans and exercise charts, because trying to remember "eat leafy greens during follicular phase" while half-asleep on BART is not it.
