Think your metabolism has slowed down, broken, or been damaged by years of dieting?
You're definitely not alone.
Maybe you could seemingly eat anything in your twenties. Maybe losing weight feels harder now you're in your forties or fifties. Or perhaps you've dieted so many times that you're convinced you've permanently damaged your metabolism.
But what if your metabolism isn't broken at all?
In this episode of The Fundamentals of Fitness, Alison Berrisford takes you inside the science of human energy expenditure to explain what's really happening.
You'll discover:
- What your metabolism actually is
- Where your body burns energy every day
- Why NEAT matters far more than most people realise
- What metabolic adaptation actually means
- Whether dieting can really "damage" your metabolism
- Why weight loss often gets harder over time
- Whether metabolism really slows down after 40
- What actually changes during menopause
- Why "metabolism-boosting" foods, teas and supplements aren't the answer
- What you can genuinely do to support your metabolism
Plus, we explore fascinating research involving more than 6,400 people across the human lifespan that challenged one of the biggest assumptions we have about ageing and metabolism.
Because your metabolism isn't a switch that suddenly breaks.
It's a dynamic system that adapts.
