Everything you were never told about your hormones – and how to make them work for you

Do you ever wish you could skip the week leading up to your period? So many of us feel like we’re riding a premenstrual roller coaster every month and, as women, we’ve learned to accept it – until now.

In this transformative book, award-winning researcher Dr Sarah Hill explains why during the luteal phase – the second half of our cycle – we feel emotional, bloated, tired, anxious and even depressed, and, most importantly, what we can do to avoid experiencing the same crash every month.

Drawing on the very latest research, you’ll find out how to:

· Sidestep PMS ‘cravings’ by eating more – you burn up to 11% extra calories in the luteal phase!

· Exercise in a way that’s invigorating instead of draining

· Understand your sex drive and why it changes across the month

· Navigate motivational and energy dips without added stress

· Use anti-inflammatory foods to ease PMS

Providing you with a science-backed roadmap to understanding PMS and the more severe form, PMDD, this book will empower you to finally take control and feel at your best whether you have your period or not.
