Is Your Metabolism Really Broken?

23 de agosto de 2026 · 23 min

Notas do episódio

Do you really have a “slow” or broken metabolism - or is something else going on?

This week on Diet Notes, Susie takes a deep dive into how metabolism actually works, what influences your metabolic rate and why changes in muscle mass, activity levels and hormones can make weight management feel increasingly difficult as you get older.

Susie also clears up some of the most common metabolism myths, including whether skipping a meal will slow your metabolism, whether you need to eat every few hours, and why simply lifting weights isn’t always enough to improve metabolic efficiency.

Plus, she explains why muscle mass, insulin resistance, meal timing, protein intake and the intensity of your training can all play a role - and why rebuilding metabolic health is often a gradual process rather than a quick fix.

In this episode:

  • What actually makes up your metabolism
  • The difference between a “slow metabolism” and metabolic inefficiency
  • Why muscle mass becomes increasingly important with age
  • How strength and higher-intensity exercise can affect the way your body uses fuel
  • Why skipping the occasional meal won’t “damage” your metabolism
  • Whether you really need to eat every three hours
  • Why Susie recommends eating more earlier in the day and less later
  • How long it can take to improve metabolic health and body composition

If you’ve ever wondered why your body seems to respond differently to food and exercise than it once did, this episode will help unpack what may actually be happening.
