5 Metabolism Lies Keeping You Stuck (and What Actually Works)

Zoë Müller & Donaé Marinus Season 1 Episode 39

Let’s get to know each other!

We’re busting the biggest metabolism myths holding women back—from “six small meals” to “no food after 7 PM,” endless cardio, magic fat-burners, and the belief your metabolism crashes at 30. We unpack what metabolism really is, why protein and strength training matter, how sleep and circadian rhythm fit in, and how to build habits that last.

🎥 We also recap our first YouTube Live Q&A (it was spicy 😅).


What you’ll learn

• Why meal content beats meal frequency

• How protein’s thermic effect gives you an edge

• Cardio vs. strength for a faster “engine”

• The truth about “fat-burning” foods/supplements

• Why metabolism stays stable 20–60 (lifestyle is the lever)


Resources mentioned

• Large lifespan metabolism study (published 2021)

• Late-eating & circadian rhythm research (published 2022)

(Note: none of this is medical advice. Talk to your healthcare provider, especially regarding GLP-1 meds.)
