In today's episode, Vanessa sits down with Dr. Howard, the lead author of a brand-new PNAS study that is challenging one of the most widely accepted ideas in human metabolism.

For years, many scientists believed that our bodies operate within a fixed daily calorie "budget," and that after a certain point, increasing activity doesn't increase total calorie burn. But Dr. Howard's new research suggests the story may be far more dynamic — and far more empowering — than we ever realized.

OneSkin is powered by the breakthrough peptide OS-01, the first ingredient proven to reduce skin's biological age. I use the OS-01 Face and Eye formulas daily—they've transformed my skin's smoothness, firmness, and glow. Visit oneskin.co/VANESSA and use code VANESSA for 15% off your first purchase.

This conversation explores what this new evidence could mean for:

How we think about calorie burn
Why activity matters (in ways we didn't fully understand before)
The role of fueling, recovery, and energy balance
What actually drives fat loss and body recomposition
How to train smarter, not harder

Mentioned in this episode:

Physical activity is directly associated with total energy expenditure without evidence of constraint or compensation — published in Proceedings of the National Academy of Sciences (PNAS).
