Are you doing everything right, eating well, exercising, sleeping, and still watching your belly grow and your energy disappear? Or maybe you've heard that menopause changes your metabolism, but nobody's actually explained what that means or what to do about it?

Today I talk with Dr. Siobhan Mitchell, one of the leading researchers on mitochondria, metabolism, and women's health.

We cover:

Why losing estrogen literally rewires how your body uses and stores energy
What happens to your gut microbiome as you transition into menopause
What GLP-1 medications are doing to your metabolism and muscle that no one talks about
A little-known molecule that is a powerful estrogen mimetic that few have heard of
What actually supports hormonal metabolic health in midlife beyond diet and exercise

Siobhan Mitchell is the chief scientific officer of MitoQ. She completed her PhD at SUNY Albany and a post-doctoral fellowship on brain aging. Siobhan held roles at the three largest food companies in the world (Unilever, Nestle and Pepsico), leading trials in Europe, North America and Asia, which investigated the effects of nutrition on cognitive decline, mood and performance. Additionally she was senior director at Noom, where she directed a team investigating chronic disease management, weight loss and mental health digital programs using cognitive behavior therapy methods. Siobhan has authored over 80 papers, and holds eight patents for aging, cognition and mood products.
