Nine Months That Count Forever

How your pregnancy diet shapes your baby's future




Jessie Inchauspé, biochemist and international bestselling author of Glucose Revolution and The Glucose Goddess Method, returns with an empowering and groundbreaking guide to pregnancy nutrition, backed by nutrition science.

Most pregnant women are told: ‘Don’t worry – eat whatever you normally eat. Your baby will get what they need from you.’ But science tells a different story: your diet during pregnancy can shape your baby’s brain, body and health for life. And somehow, no one has told you the rules. Until now.

When biochemist Jessie Inchauspé became pregnant, she sifted through hundreds of studies and uncovered striking research: choline, DHA, protein and glucose are four key nutrients that can influence a baby’s development in the womb; yet most women don’t get nearly enough of the first three – and too much of the fourth. And the effects can last a lifetime.

In 9 Months That Count Forever, Jessie reveals science-based hacks to optimise these four nutrients and help give your baby a stronger foundation for life.

These principles can:
- support your baby’s brain development, cognitive growth and emotional resilience
- help lower their risk of health challenges later in life
- influence your baby’s body composition, organ function and long-term metabolism

Complete with guidance on supplements, nausea, labour and breastfeeding, as well as meal plans and recipes, 9 Months That Count Forever also shares Jessie’s deeply honest account of her own pregnancy journey, offering support and reassurance through these crucial months.

This landmark book reveals the extraordinary power mothers hold during pregnancy – and is an essential companion for every parent-to-be.

'This book cuts through confusion with science and heart. Clear, evidence-based and empowering, it’s an essential guide for anyone who wants to understand how food supports life from the very beginning.'
Mark Hyman, MD, #1 New York Times bestselling author of Young Forever and Food: What the Heck Should I Eat

Praise for Nine Months That Count Forever

In this groundbreaking book, Jessie Inchauspé shines a long-overdue light on the critical role of blood sugar health during pregnancy, not only for a mother’s well-being today and across her lifetime, but also for the health of the next generation. It offers healthcare providers and mothers-to-be the answers I have shared with women for decades in my work as a midwife and physician. I am thrilled to see this knowledge so clearly articulated and widely amplified. We have the opportunity to profoundly impact women’s lifelong health, and pregnancy is one of the most powerful times to do so. This book is an important key.

Aviva Romm, MD, midwife, New York Times bestselling author of Hormone Intelligence and The Natural Pregnancy Book, and founder of The Mama Pathway

I love this book. Jessie Inchauspé’s Nine Months That Count Forever is a revelatory guide that transforms the outdated ‘bun in the oven’ myth into an empowering call to action, showing how everyday food choices during pregnancy can profoundly shape a baby’s brain, body, and lifelong health. Backed by rigorous science and laced with the author’s warm, personal insights, it’s the essential companion every expecting parent needs to nourish not just survival but thriving.

As a registered dietitian who has spent her career helping women understand their bodies, I can say this book is a breakthrough. In a world where women are still expected to navigate pregnancy with guesswork and guilt, Jessie offers truth, science, and grounding. She has a rare ability to turn complex biology into practical, life-changing tools, giving women clarity instead of confusion, and empowerment instead of fear. This work is not just helpful – it’s revolutionary. Every woman deserves the knowledge in these pages.

Jessie’s book offers beautifully clear, science-based guidance to help expectant mothers optimize their babies’ health. By focusing on essential nutrients like choline and omega-3s, she makes it easy to understand how to best nourish the developing baby’s brain and body. This book is not just a guide, it is a blueprint for maximizing the potential embedded in pregnancy and beyond. I highly recommend this vital information for all future mothers.
