What WomanCode and In the FLO do well

Alisa Vitti's two books — WomanCode (2013) and In the FLO (2020) — deserve credit for bringing cycle syncing into mainstream awareness. They introduced millions of women to the concept that the female body operates on a monthly rhythm and that aligning daily life with that rhythm produces better outcomes than fighting it.

WomanCode is primarily a healing guide. It is built around restoring hormonal health in women dealing with conditions like PCOS, endometriosis, irregular cycles and post-pill hormonal disruption. It is thorough, empathetic and covers the full spectrum of hormonal health from a functional nutrition perspective. Best for women who have a known hormonal condition and want a whole-system healing approach.

In the FLO is the practical follow-up — a 28-day biohacking programme covering food, exercise, relationships and work by phase. More action-oriented than WomanCode and better suited to women who are already broadly healthy and want to optimise their daily life using their cycle. Best for women who want a structured whole-life approach to cycle syncing.

Is WomanCode worth reading?
Yes — particularly for women dealing with hormonal conditions like PCOS, irregular cycles or post-pill hormonal disruption. WomanCode by Alisa Vitti is one of the most comprehensive guides to restoring hormonal health through nutrition and lifestyle. It is less focused on training and performance optimisation and more on healing and rebalancing.

Where they fall short — and what is missing

Both books were written for a general women's health audience and are necessarily broad. What they do not provide is specific, phase-mapped training protocols for women who exercise — what to lift, when to push, when to pull back, what the research says about oestrogen and muscle protein synthesis, how to structure a training week that accounts for both follicular peak performance and luteal phase catabolic pressure.

The nutrition guidance in both books is also general. Neither provides the specific phase-by-phase food guidance — iron after menstruation, cruciferous vegetables for oestrogen metabolism in the follicular phase, magnesium and complex carbohydrates in the luteal phase — that active women need to make their nutrition work with their cycle rather than against it.

WomanCode is the bible. In the FLO is the practice. The Women's Hormone Blueprint is the performance manual — for the woman who trains and wants real results.

The Women's Hormone Blueprint — where it fits

The Women's Hormone Blueprint by Zōē is not trying to replace WomanCode or In the FLO. It is built for a specific woman: active, performance-focused, wanting to understand exactly how her hormonal cycle affects her training, nutrition and energy — and exactly what to do about it in each phase.

It is more specific and more actionable than either Vitti book on the questions that matter most to women who train: which sessions to push, which to pull back, what to eat when and why, how to manage fat loss through hormonal transitions, and how to understand the signals your body sends in each phase. At 60 pages with pocket guides, a phase tracker and cycle diagrams, it is designed to be used — not just read.

What is the best WomanCode alternative for active women?
The Women's Hormone Blueprint by Zōē is specifically designed for women who train and want phase-specific training and nutrition guidance. It covers all four hormonal phases with practical protocols for workouts, food timing, fat loss and recovery. $37 digital download at byzoewomen.com — more targeted than WomanCode for performance-focused women.
Is The Women's Hormone Blueprint a good In the FLO alternative?
For women whose primary goal is training and nutrition optimisation rather than a full lifestyle overhaul: yes. The Women's Hormone Blueprint provides more specific training and nutrition protocols than In the FLO. For women wanting a complete life restructure around their cycle — relationships, work, creativity — In the FLO remains comprehensive. The two are complementary rather than competing.
