The Invisible Decade: Understand your hormones, reclaim your energy, and feel yourself again

There is a decade in every woman's life that almost no one prepares her for.It often begins in your mid-thirties — years before anyone says the word "menopause." Sleep that no longer restores you. A mood that turns without warning. Weight that won't shift. Brain fog mid-sentence. You go to your doctor, the labs come back "normal," and you're told you're simply too young. So you go home feeling like a stranger in your own body — and no one can tell you why.This book tells you why.Written by women's health scientist Mona Poulev (M.Sc.), drawing on more than fifteen years of work with over a thousand women, The Invisible Decade is the clear, honest handbook for perimenopause that most women are never given.Inside, you'll find:A plain-language map of what actually happens in your body — hormones, brain, metabolism, sleep, mood, bones — from your thirties into your fifties and beyondThe truth about why this knowledge was withheld for decades, and how one misread study shaped a generation of careAn evidence-informed look at hormone replacement therapy: routes, timing, risks, and the myths that still circulateThe diagnostics worth asking for — and how to read your own values against functional ranges, not just "normal"The lifestyle levers with the greatest impact: strength, protein, blood-sugar stability, sleep, and nervous-system regulationA symptom-to-cause map, lab tables, and a practical 90-day plan to turn knowledge into actionPerimenopause is not a deficit and not a decline. It is a transition — and with the right understanding, it becomes a turning point.If you have ever sensed that something is different and finally want to understand why, this book is for you.This book is for education and is not a substitute for individual medical advice. Mona Poulev is a nutrition scientist (M.Sc.), not a physician. Read more
