Summary

In this episode, Vanessa breaks down one of the most important conversations on the podcast to date — her interview with Dr. Carlene Starck on newly published research suggesting that protein requirements may be significantly higher than current guidelines.

Vanessa dives into what this new model reveals about how the body actually uses — and loses — amino acids every day, and why many people may be under-eating protein even when they think they're eating "high protein."

She explains how overlooked factors like gut losses, amino acid oxidation, and protein turnover may be driving higher true protein needs — and what this means for fat loss, muscle retention, satiety, and metabolic health.

This episode also highlights why protein quality matters, why essential amino acids are the real drivers of results, and why some protein sources may be far more effective than others when it comes to body recomposition.

If you're trying to lose fat, preserve muscle, or optimize your metabolism — this episode connects the dots between cutting-edge research and practical application.

In this episode:

  • Why protein requirements may be higher than current guidelines

  • Hidden amino acid losses (gut, oxidation, turnover)

  • Why "high protein" may still not be enough

  • Essential amino acids vs total protein

  • Why protein quality impacts fat loss outcomes

  • Animal vs plant protein efficiency

  • Protein, satiety & appetite regulation

  • How protein supports muscle retention in fat loss

  • Practical protein targets for body recomposition

The PSMF Library is officially live for pre-order 🎉

This is a resource Vanessa created based on what worked so effectively for her for fat loss and body recomposition — using a structured, high-protein approach instead of trying to restrict calories every single day.

Instead of guessing what to eat or starting over each week, this framework provides a clear, repeatable way to structure nutrition using high-protein, lower-energy days alongside maintenance days.

What's included:

  • 📘 Printed PSMF Library (premium quality edition)
  • ⚡ Instant digital access

  • 🥩 High-protein, low-carb recipe library

  • 🧠 Tiered system for PSMF + maintenance days

  • 🛒 Grocery lists and planning tools

  • 👥 3 months of community access and support

Welcome to the optimal protein podcast. I'm Vanessa Spina.

Hello, my friends. Welcome back to the optimal protein podcast. I'm your host Vanessa.

0:10.4

And today's episode is a deep dive recap of one of the most important conversations that we've had on the podcast recently.

0:19.0

My interview with Dr. Carleen Stark. This is one of those

0:23.2

episodes that I truly believe has the potential to change how we think about protein, not just for

0:30.3

muscle building, but also for body recomposition, fat loss, satiety, optimizing metabolic health and wellness, and even our gut health.

0:40.7

Now, the research that Dr. Carleen Stark is doing is absolutely groundbreaking, and I think she

0:47.6

is one of those incredibly brilliant scientists that we will look back on, or other people will

0:54.1

look back on in the future and honor

0:56.9

as one of those people who made extremely valuable groundbreaking contributions to our current

1:05.7

understandings of things like protein nutrition and amino acid nutrition.

1:11.8

Now, Dr. Carleen Stark works with an incredible group in New Zealand, which includes Dr.

1:17.6

Bob Wolf, who is one of the goats, I guess there are a few out there, one of the greatest

1:22.7

of all time when it comes to protein and amino acid nutrition and research. And the latest cutting edge

1:31.2

paper that she just published is extremely exciting. So she reached out to me to let me know

1:38.3

that it had been published. And we had talked about having her come back on as soon as this new study came out.

1:46.6

So this is cutting edge, hot off the presses, brand new information from this most recent

1:53.0

publication by Dr. Stark.

1:55.3

And it suggests that our protein requirements may actually be significantly higher than we previously thought. And today I'm going

2:04.4

to break all of it down for you. What this new study actually found, why current protein

2:09.9

recommendations may be flawed, what's really happening with amino acid losses in the body,

2:17.4

why protein quality matters more than ever,
