In this masterclass episode, Vanessa sits down with Dr. David Church, one of the most exciting young researchers in protein metabolism and a mentee of Dr. Arny Ferrando and Dr. Robert Wolfe. Together, they break down the latest science on protein timing, distribution, and supplementation — and how to apply it to achieve fat loss, preserve muscle, and enhance cognition.

You'll learn:

• How stable isotope tracer studies work and what they reveal about muscle protein synthesis (MPS).

• The minimum protein per meal needed to trigger muscle growth and repair — and whether you can hit it with two meals a day.

• The truth about intermittent fasting and muscle preservation — what happens to MPS in 2-meal and 1-meal-a-day patterns.

• Why older adults and women over 40 face anabolic resistance and how EAAs (essential amino acids) can help overcome it.

• What happens when you double your protein intake from 0.8 g/kg to 1.6 g/kg — and why distribution may matter less than total intake.

• The surprising power of small doses of EAAs in muscle maintenance and cognitive support.

• Why creatine is foundational for women, including new research showing benefits for brain health and sleep deprivation.

• How to optimize body recomposition — burning fat while protecting lean mass — even during calorie restriction.

• The difference between supplemental vs. replacement nutrition, and why EAAs work for older adults with low appetite.

• The synergy of protein + resistance training + sleep + activity in driving sustainable fat loss.

Dr. Church also shares his own daily stack — including why he takes 20 g of creatine per day and combines it with EAAs for energy, cognition, and recovery — plus his favorite high-protein meals for busy days.

If you've ever wondered how to burn fat efficiently while protecting every gram of muscle, this episode is packed with evidence-based takeaways you can implement right away.
