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).
