Why You Can’t Lose Weight Anymore (Even in a Calorie Deficit)

sally oneill podcast kira sutherland lose weight calorie deficit

One of the most common frustrations I hear from clients is: “I’m eating in a calorie deficit and training hard, but the weight just won’t shift.”

If that sounds familiar, you’re definitely not alone, and there are very real physiological reasons behind it.

I recently joined Sally O’Neil on her podcast to talk through why fat loss often feels harder as we move through our 30s, 40s, and beyond.

It’s not about being “broken” or doing something wrong; it’s about understanding how your hormones, metabolism, recovery, and muscle mass all change with age, and how to work with your body instead of against it.

In this episode, we cover:

  • Why the old “eat less, move more” approach often stops working after 30
  • How stress, cortisol, and perimenopause influence fat storage
  • The crucial connection between muscle mass and metabolism
  • Why so many women are under-recovering rather than overtraining
  • Key strategies like blood testing, bone density checks, cycle syncing, and tracking body composition

If you’ve been feeling stuck despite your best efforts, this episode will help you understand what’s really going on under the surface and how to take a smarter, kinder approach to your health.
