Should women intermittent fast, or does meal timing matter more?

In this conversation, we explore the difference between intermittent fasting and time-restricted eating, why eating in sync with your circadian rhythm may support metabolic health and sleep, and why these considerations can become increasingly important during the menopause transition.

We also discuss early versus late eating windows, eating close to bedtime, protein and fiber, and the common mistakes people make with melatonin.

$How to Build Bone Density After 40: Resistance Training, HRT, and Creatine Your bones dont just start failing at menopause. The cascade starts years before your last period, and most women dont find out until a wrist fracture at 50 tells them they were already decades behind. In this episode, I sit down with Dr. Tracey Clissold, founder of OSTEO-GAINS and a bone health and jump training specialist, and Dr. Jocelyn Wettstein, orthopedic surgeon and womens musculoskeletal health researcher at Duke University, to cover everything active women need to know about building and protecting bone across the female lifespan. We get into why common exercise approaches arent enough, what actually moves the needle on bone density, and how to stack exercise, nutrition, and hormonal tools together for a skeleton that stays robust well into your 60s and beyond. This is a science-first episode for active women who want to stay strong, resilient, and structurally robust across every decade of life. Dr. Tracey Clissold is a New Zealand-based researcher and educator with 30+ years in exercise science and sports nutrition. She holds a PhD from AUT University, where her research proved that a targeted jump-landing program can improve bone mineral density by 3.5–5% in just 12 months. She created the OSTEO-GAINS app — a science-backed, 2–5 minute daily bone-building program with over 25,000 users worldwide. 🔗 osteo-gains.com | @osteogains Dr. Jocelyn Wittstein is a board-certified orthopedic surgeon, sports medicine specialist, and associate professor at Duke University Medical Center. A nationally recognized expert in womens musculoskeletal health, she leads NIH-funded research on bone density, joint health, and the musculoskeletal effects of menopause.
