This week on Bountifull, I’m joined by Brittany McNabb for the first in a four-part series exploring health, wellbeing, food and fitness from a very different angle.
Brittany is a personal trainer with a background spanning psychology, business, psychotherapy, nutrition, meditation and behaviour change. Her work starts from a simple idea: lasting change is about far more than calorie deficits, macros or what you do at the gym.
Brittany describes much of the health and fitness industry as focusing on the tip of the iceberg: the habits, meal plans, macros and training programmes we can see. Her work goes underneath that, into our identity, beliefs, nervous system, conditioning and capacity for change. Because the goal isn’t simply to achieve a result. It’s to find an approach to health that you can actually sustain — one that builds your strength, energy and capacity for life rather than requiring you to make your life smaller to maintain it.
But first, we go back to Brittany’s own story. We talk about growing up as a Jehovah’s Witness, severe bulimia and anorexia, shame, perfectionism, miscarriage, birth trauma, significant weight gain and the journey that eventually led her to lose 40 kilos, rethink her relationship with health and build a business helping thousands of women create lasting change.
It’s the story behind the work, and the foundation for everything we’ll explore next.
Episode Highlights

How shame, perfectionism and not feeling “good enough” can shape our behaviour
