Discover how your 28-day hormonal cycle can revolutionize your productivity, health, and happiness. "In the FLO" challenges traditional one-size-fits-all wellness approaches with female-specific biohacking that's transformed countless women's lives. What if your "hormonal disadvantage" is actually your greatest untapped superpower?
Alisa Vitti is the bestselling author of In the FLO and a pioneering expert in women’s hormonal health and functional nutrition. A Johns Hopkins graduate and founder of FLO Living, she developed the Cycle Syncing Method®—a proprietary framework that aligns diet, exercise, and lifestyle with the female infradian rhythm to optimize energy, fertility, and overall wellness.
Her work, rooted in her personal journey healing from polycystic ovarian syndrome (PCOS), has helped thousands resolve menstrual disorders, boost fertility, and reclaim hormonal balance without medication.
Vitti’s previous book, WomanCode, established her as a leading voice in holistic menstrual health, while her FLO Living platform and top-ranked MyFLO app provide tools for symptom tracking and personalized care. A sought-after speaker, she has presented at TED and SXSW and been featured in The New York Times, Forbes, and Vogue. Her methodology is backed by clinical research with Columbia University and has sparked a viral wellness movement, with over 125 million #cyclesyncing mentions on social media. In the FLO continues her mission to revolutionize women’s healthcare through science-backed, natural solutions.
In the Flo provides a science-backed approach for women to optimize health and productivity by aligning daily routines with their 28-day hormonal cycle. It introduces the Infradian Rhythm and Cycle Syncing Method®, offering dietary guidelines, workout plans, and stress-management strategies tailored to each menstrual phase. The book emphasizes leveraging biological rhythms to improve energy, focus, and overall well-being.
This book is ideal for women experiencing hormonal imbalances (PCOS, PMS, endometriosis), professionals seeking productivity hacks, or anyone interested in biohacking their health. It’s particularly valuable for those tired of rigid diets and one-size-fits-all wellness advice, offering personalized strategies grounded in chronobiology.
Alisa Vitti’s signature framework syncs diet, exercise, and work routines with the four menstrual phases:
This method aims to reduce burnout by aligning activities with hormonal shifts.
The book provides phase-specific meal plans:
Vitti argues traditional dieting fails women by ignoring cyclical metabolic changes, advocating instead for nutrient-dense eating patterns that adapt monthly.
Some readers note limited peer-reviewed citations for certain claims, particularly around Chinese medicine integrations. Critics suggest combining Vitti’s insights with clinical medical advice for complex hormonal conditions. The book’s focus on 28-day cycles may also require adaptation for irregular cycles.
It rejects male-centric “grind culture,” proposing a cyclical workflow:
This approach claims to boost output by 30% while reducing fatigue.
The Infradian Rhythm refers to women’s 28-day biological clock governing hormone production, metabolism, and brain chemistry. Vitti contrasts this with the 24-hour circadian clock, showing how ignoring longer rhythms contributes to chronic fatigue and hormonal disorders.
Workouts are tailored to hormonal states:
The book argues this prevents overtraining and accelerates results by matching intensity to energy availability.
Unlike symptom-focused guides, it offers a systemic view linking hormonal health to career performance and relationships. Unique tools include the DailyFLO Planner and Motherhood Easier Chart, providing actionable templates for cycle-based living.
Vitti identifies the luteal phase as a vulnerability window for adrenal fatigue. Strategies include:
This phased approach claims to lower cortisol by 40%.
Yes, the FLO Protocol included in the book addresses root causes of infertility like insulin resistance and inflammation. By optimizing cycle regularity through diet and lifestyle, many users report improved ovulation tracking and conception success.
While WomanCode focuses on fixing hormonal dysfunction, In the Flo targets high-performing women seeking to leverage their biology for peak performance. The newer book expands on workplace strategies and includes updated nutrition science.

What if everything you've been told about maintaining consistent productivity is fundamentally wrong-at least for half the population? Women worldwide push through fatigue, brain fog, and hormonal chaos, believing the solution lies in more willpower, better time management, or the right supplement. Meanwhile, science has quietly documented a second biological clock that governs female energy, creativity, and metabolism-one that's been systematically ignored. This isn't about working harder. It's about discovering that your body operates on a 28-day rhythm with four distinct phases, each offering unique cognitive and physical advantages. When you align with this rhythm rather than fight against it, something remarkable happens: symptoms vanish, energy stabilizes, and productivity soars-not through force, but through flow.
