If you’ve ever looked down at your belly in your 40s and thought… “Where did that come from?” this one’s for you.

I first discovered Angela Foster through The High Performance Health podcast, which I binged. I was left thinking, “where has this woman been all my life?” She was asking the exact questions so many of us are quietly thinking, especially when our bodies start to change in midlife. Today I’m sitting down with Angela to unpack what’s actually happening when we begin storing more fat around the middle, why sleep suddenly becomes so hard to maintain, why sugar cravings ramp up, and why the old strategies just stop working.

The big ideasKey Takeaways

  • 01Midlife belly fat is about more than ageing. Changing hormones, insulin resistance and stress all shift how and where our bodies store fat.
  • 02Sleep and belly fat are linked. Waking at 2 or 3am and poor sleep quality can quietly drive weight gain around the middle.
  • 03The old strategies stop working. Fasting needs a rethink in midlife, and 20 minutes of the right exercise can bring huge benefits.
