Understanding the Truth About Calorie Deficits
 

You've heard it before: "The only way to lose weight is a calorie deficit." And while that statement is technically true, it's also one of the most oversimplified pieces of fitness advice on the internet.

In this episode, I'm breaking down what a calorie deficit actually is, why it's not as simple as "eat less and move more," and why some women may need to focus on maintenance calories before worrying about fat loss.

If you've ever felt stuck, frustrated, or confused about why eating less isn't working anymore, this episode is for you.

Episode Recap:

  • What a calorie deficit actually is and how it works
  • Why fat loss requires a calorie deficit - but that doesn't mean starvation
  • Why "eat less, move more" isn't always helpful advice
  • How your starting point determines your fat-loss approach
  • When maintenance calories may be more beneficial than a deficit
  • What reverse dieting is and who it may help
  • How calorie deficits connect to body recomposition
  • Signs your calorie deficit may be too aggressive
