In the FLO: Unlock Your Hormonal Advantage and Revolutionize Your Life
Shows women how to plan work, meals, rest and sex around the four hormonal phases of a 28-day cycle, so they get more done with less strain and stop dismissing their symptoms.

1. Introduction
1 min 01 sec
Many women run their lives on a schedule built for a body that never changes, then blame themselves when energy, mood and focus swing across the month. In In the FLO, nutritionist Alisa Vitti argues that those swings follow a pattern: a 28-day hormonal cycle with four distinct phases, each suited to different kinds of work, food, movement and rest. A woman who plans around that pattern, instead of pushing through it, gets more done and feels better doing it.
Vitti came to this through her own health. For seven years she was told her symptoms were in her head, until her own research pointed to polycystic ovary syndrome. The approach she built afterwards, the Cycle Syncing Method, treats the monthly cycle as a second body clock to work with. Ahead: why that clock gets ignored, what each phase brings, and how to fit a real month of meetings, meals and deadlines onto it, even in a rigid office job.
2. Talk about your body without the old shame
1 min 28 sec
A school biology textbook gave one set of organs the starring role and the other a walk-on part. Vitti traces how that kind of language follows women into adulthood and into the choices they make about their health.
3. Take period pain as seriously as a cold
1 min 29 sec
A sniffle earns rest, medicine and sympathy. Monthly pain that lasts for days usually earns a shrug. Vitti argues that this gap has real consequences, and she learned it the hard way over seven years.
4. Meet the monthly clock behind your energy
1 min 17 sec
Everyone knows the body keeps time across a day. Far fewer know it keeps a second schedule across a month, and that the two clocks can throw each other off in ways that show up as poor sleep or irregular periods.
5. Know what each of the four phases offers
1 min 33 sec
Some days your mind feels sharp and social, and some days it wants a quiet room. Vitti links those shifts to four hormonal stages, and each one turns out to be good at something different.
6. Plan your month in four energy seasons
1 min 33 sec
Vitti used to hit big deadlines by running herself into the ground and paying for it afterwards. A four-letter planning frame changed that, and it rests on an idea farmers have relied on for a very long time.
7. Eat for the phase you are in
1 min 39 sec
Cutting calories and adding punishing workouts often ends with the weight returning and a sense of failure. Vitti offers a different way to eat, one that changes the menu as the month moves on.
8. Intimacy that follows the shape of your month
1 min 30 sec
Desire that comes and goes can feel like a problem with you or with your relationship. Vitti suggests a simpler explanation, and a phase-by-phase way to enjoy sex more at every point in the cycle.
9. Stay in sync with your cycle in a nine-to-five job
1 min 31 sec
Most offices run on the same timetable every day of the month. One overworked entrepreneur and a five-step planning routine show how much room there still is to work with your cycle instead of against it.
10. Conclusion
1 min 05 sec
Vitti’s book asks women to stop treating the month as thirty identical days. The body she describes changes on a schedule: a creative opening, a short social peak, a long stretch suited to finishing work, and a few days that call for rest. Much of the trouble she sees, from crash diets to burnout to symptoms dismissed for years, comes from ignoring that schedule. She presents cycle syncing as a way to support hormonal health and, through it, a career, a relationship and a sex life that last.
The starting point is knowing which phase you are in today. From there, the moves are small. Put the hard conversations and big meetings in your ovulatory days. Before your period, cut the to-do list down to what truly must happen. And when you feel more drained than usual, look for what Vitti calls energy leaks: short sleep, skipped meals, taking on too much and never asking for help. Find where the time and energy are going, then close the gap.
Farmers learned long ago that soil left to rest gives a better harvest. Vitti’s claim is that a woman’s month works the same way.
About this book
What is this book about?
Many women live by a routine built for a body that never changes. When their energy, focus and mood swing across the month, they push through, try another crash diet or accept that period pain is simply part of life. Alisa Vitti argues that these swings follow a predictable pattern, and that ignoring it costs women their health and their best work. Vitti, a functional nutritionist whose own symptoms went unexplained for seven years before she traced them to polycystic ovary syndrome, describes a second body clock that runs alongside the daily one: the monthly cycle, with four phases that each bring different strengths. She explains how social stigma, poor sex education and medical dismissal keep women from paying attention to it. Her answer is the Cycle Syncing Method. It matches meetings, deadlines, meals, exercise and intimacy to the follicular, ovulatory, luteal and menstrual phases, using a simple frame she calls POWR. Readers get a phase-by-phase map of what to eat, when to socialize, when to finish projects and when to rest, plus a planning routine that works even in a rigid office job.

This book is a total game-changer for anyone tired of feeling like their own body is a complete mystery. Vitti breaks down exactly why women shouldn't be following a lifestyle designed for the standard male 24-hour hormonal cycle. To be fair, I never realized how much my productivity was suffering because I was trying to force a linear schedule onto a cyclical biology. Learning about the Infradian Rhythm was like someone finally handed me the manual to my own hardware. While the tone can get a bit repetitive, the actual advice on diet and exercise for each phase made a tangible difference in my energy levels within weeks. I feel more empowered and less like I’m fighting an uphill battle every month. It’s about time we stopped treating our periods as a nuisance and started using them as a performance-enhancing tool for our careers.
Show moreFinally, someone explains why the standard health and wellness advice often fails women who are in their reproductive years! Truth is, most of the research out there is based on men, and Vitti does an excellent job of highlighting how our needs change every single week. Since I started adjusting my workouts—focusing on HIIT during my follicular phase and restorative yoga during my luteal phase—my periods have become significantly less painful. The lifestyle design method presented here is intuitive and flexible, allowing for a gradual transition rather than an overnight overhaul. It’s a must-read for anyone wanting to unlock their hormonal potential and stop feeling like a victim of their own cycle. I only wish I had known about these biological patterns in my early twenties instead of struggling for so long.
Show morePicking this up was the best decision I’ve made for my wellness this year. For years I thought my mood swings and fatigue were just things I had to endure, but this book taught me how to work with my hormones rather than against them. Actually, it’s a bit of a dense read at times, and some parts feel like a repeat of her previous work. However, the empowerment I felt after finishing it was worth every minute of reading. If you want to understand your body on a deeper level and stop the cycle of burnout, you need to grab this. It’s basically a biological roadmap for thriving in a world built for men. Highly recommend for every person who menstruates! You won't regret it.
Show moreHonestly, every woman needs to read this book—no excuses! It acted as the 'long overdue talk' I never got from my doctors or my family. Most of us grow up being told that pain is normal, but this book shows that it’s actually a sign of hormonal imbalance that we can fix. The practical advice on diet changes has already helped me stabilize my moods, which used to be a total rollercoaster every month. I love how it encourages an intuitive way of living that honors our natural rhythms instead of suppressing them with birth control. While the author does spend a lot of time telling you how great her method is before actually explaining it, the 'aha' moments are worth the wait. It’s an eye-opening guide that makes you realize you aren't crazy, you’re just cyclical.
Show moreAfter hearing so much buzz about 'In the FLO,' I decided to see if the hype was real or just good marketing. In my experience, the core message about the Infradian Rhythm is revolutionary, especially for women who feel like they can't keep up with the 24-hour hustle culture. Vitti explains the science—or at least her version of it—in a way that is easy to understand and implement. I did find the sections on 'feminine energy' a bit eye-roll inducing, and the formatting could have been way more concise. That being said, the charts for food and exercise are incredibly useful as a quick reference guide. It’s a 4-star book because the information is life-changing, even if the delivery is a bit repetitive and occasionally leans too hard into self-promotion.
Show morePersonally, I found this book to be a helpful introduction to women's health awareness, though it definitely has its flaws. The truth is, I’ve been following the advice to change my diet based on my cycle for a month now and I already feel significantly better. It’s empowering to understand the biological reasons why I feel more social one week and more introspective the next. However, I have to agree with other reviewers that the book feels like one long advertisement for the author's ecosystem of products. It’s also quite similar to WomanCode, so if you’ve read that one, you might want to skim this instead of reading every word. For a total beginner, it’s a goldmine of info, but for someone already well-versed in hormonal health, it might feel a bit redundant.
Show moreThe chapter on the Infradian Rhythm alone makes this book a worthwhile purchase for anyone struggling with hormonal issues. It’s a shame the useful advice is buried under so much fluff and constant references to the author's app. To be fair, the shift in how I view my productivity has been massive; I no longer beat myself up for needing more rest during my menstrual phase. I do think the author's dismissal of traditional medical advice can be a bit extreme at times, and she should be more careful with how she discusses eating disorders. But the basic premise—that we should live in a way that supports our hormones—is something every woman should hear. It’s not a perfect book. However, it is necessary for changing the conversation around female biology.
Show moreWhile the concept of cycle syncing is absolutely brilliant, the execution of this book left me feeling like I was trapped in a 300-page infomercial. Frankly, it felt like a slightly expanded version of her first book, WomanCode, but with much more aggressive marketing for her proprietary app and supplement line. I appreciate the message that we need to listen to our bodies and adjust our habits based on our phases, but the constant 'buy my program' vibes diminished my trust in the information. There is definitely good stuff in here about managing your workflow and relationships, yet you have to sift through a lot of fluff to find the practical steps. It’s a solid introduction for beginners who have never considered their hormones, but experienced 'syncers' might find it redundant and overly salesy.
Show moreLook, the core message here is vital, but the book itself could have been about a hundred pages shorter without losing any value. There is so much 'paja' or filler content that it sometimes feels like Vitti is just trying to hit a word count. Personally, I found the chapters on work and relationships to be the most insightful because they offer a perspective I’ve never seen in other health books. It’s fascinating to think about how our brains actually change throughout the month, affecting everything from our communication style to our libido. I do wish she acknowledged that not everyone has the career flexibility to shift their schedule as drastically as she suggests. It feels a bit elitist in that regard. Still, the underlying framework is a solid tool for anyone looking to live more naturally.
Show moreI really wanted to love this, but the lack of scientific grounding and the occasional victim-blaming narrative made it a difficult read. To be fair, the idea of exercising in sync with your cycle is helpful, but claiming that deep-seated conditions like endometriosis can be solved by addressing 'repressed emotions' is irresponsible and dangerous. Endometriosis is a physical disease that often requires surgery, not just a change in mindset or feminine energy. Furthermore, the author continues to push debunked myths about soy and uses terms like 'adrenal fatigue' which isn't a recognized medical diagnosis. Not gonna lie, the constant plugging of her center and app made the whole thing feel less like a health guide and more like a revenue stream. There are better, more evidence-based books out there for women’s health that don't rely on such 'woo-woo' logic.

What is the main idea of In the FLO by Alisa Vitti?
Vitti argues that women have a second body clock, a monthly hormonal cycle with four phases: follicular, ovulatory, luteal and menstrual. Each phase brings different energy and mental strengths. Living the same routine every day works against this rhythm. Her Cycle Syncing Method matches work, food, exercise, rest and sex to each phase, which she says supports hormonal health and helps women achieve more with less effort.
What does POWR stand for in In the FLO?
The acronym POWR covers Prepare, Open up, Work and Rest, with one word assigned to each phase of the cycle, beginning with the follicular. Vitti uses it to plan her month: big meetings and social events go in the ovulatory Open up phase, and a few days before her period she trims her to-do list to the two or three tasks that must get done and moves the rest.
What should you eat in each phase of your cycle according to Alisa Vitti?
Vitti suggests light, fresh food such as kimchi salads, carrots, chicken, trout and oats in the follicular phase. Around ovulation she favors tomatoes, spinach, berries, quinoa and corn to help the liver process extra estrogen. In the luteal phase she advises more calories, B vitamins from cooked greens like watercress, root vegetables and millet. During menstruation she recommends more protein, healthy fat, red meat, kidney beans and buckwheat.
How can I use cycle syncing in a job with a fixed schedule?
Vitti offers a planning routine. List what you must deliver in the coming month, map your cycle phases onto the calendar, and place flexible projects in the phases that suit them. Add fixed deadlines wherever they fall, remove nonessential tasks from your menstrual phase, then schedule team meetings and bring each phase’s strengths to them. Her client Allie also stopped hard morning workouts and left work at 5:00 p.m. during her period.
Who should read In the FLO?
It suits women who feel their energy and mood change across the month and want to plan around it, especially busy professionals, founders and parents prone to overwork. It also speaks to women whose period pain or PMS has been brushed aside, since Vitti, who spent seven years being told her symptoms were in her head, argues these symptoms deserve real attention.
