Perimenopause Fitness and Nutrition, Backed by Research

Your body isn't broken. It's running on different rules now.

Perimenopause changes how your body handles fat, muscle, hunger, and sleep, at a hormonal level. Most fitness advice was never built for this. This book explains exactly what changed and gives you a science based plan to work with it, not against it.

Why this book, and not another generic guide

Mechanism, not motivation

Every chapter explains the actual hormonal mechanism behind what you're experiencing: estrogen, ghrelin, muscle loss, sleep disruption. Once you understand why, the plan makes sense.

Built from real research

Drawn from published research and guidance from organizations including the American College of Sports Medicine, The Menopause Society, and peer reviewed studies, not trends or influencer opinions.

A plan you can start today

Chapter 6 turns the science into a simple four week starting structure, so you're not left with information and no next step.

Common questions

Why do I gain weight in perimenopause even when nothing about my diet changed?

Fluctuating estrogen changes how your body metabolizes and stores fat, often shifting it toward the abdomen. Hunger hormones like ghrelin also run higher, and muscle mass, which burns more energy at rest, naturally declines. This is a hormonal shift, not a sign you're doing something wrong. Chapter 1 covers the full mechanism.

Is strength training safe during perimenopause?

Yes. Major health organizations recommend two to three full body resistance sessions per week during this transition. Chapter 3 covers exactly how to structure this, including load and frequency.

How much protein do I actually need?

Most current research points to roughly 1.2 to 2.0 grams per kilogram of body weight per day during perimenopause, notably higher than the standard RDA. Chapter 4 breaks this down by body weight with practical meal examples.

Will lifting weights make me bulky?

No. Visible bulk requires a specific, sustained combination of training volume, calorie surplus, and hormonal conditions most women do not have. Resistance training here typically improves body composition and bone density instead.
