Belinda Beck, founder of The Bone Clinic and a leading authority on exercise physiology and bone health, delves into the science of osteoporosis, bone density, and the lifelong importance of maintaining skeletal health. In this episode, she explains how the foundation for strong bones is established during childhood, offering valuable advice for parents on optimizing bone health for their kids. She also explores how bone remodeling occurs throughout life, driven by activity, nutrition, and hormones. Belinda highlights the power of resistance training in improving bone strength, even for those at risk of bone loss, and emphasizes the role of essential vitamins and minerals in maintaining bone health. She shares practical strategies, backed by research, for preventing fractures and combating osteoporosis.

We discuss:

Belinda’s journey into bone health research and training [2:45];
The physiology of bone and how bones adapt to mechanical loading [8:15];
Bone development from birth to adulthood, why early life is a crucial period, the functions of osteoblasts and osteoclasts, and gender differences in BMD [14:00];
How parents can optimize their children’s bone health through diet (calcium and vitamin D), sunlight exposure, and physical activity [27:30];
The best sports and activities for promoting bone health, weight training for kids, and advice for parents [36:30];
The impact of corticosteroid use on bone health in children and strategies to minimize negative effects [48:30];
Advice for people in middle age to preserve bone density: physical activity and bone-loading exercises [52:00];
Bone loss during the menopause transition for women: hormone replacement therapy and other strategies to mitigate BMD losses [59:30];
Interpreting the bone mineral density results from a DEXA scan: T-score, Z-score, and more [1:03:00];
The LIFTMOR study: testing the effects of heavy weightlifting on bone health in postmenopausal women with low bone density [1:10:15];
Profound benefits of weight training outside of BMD improvements: exploring the broader impacts on patients in the LIFTMOR study [1:19:30];
Guidance for people wanting to use exercise designed to improve their bone health [1:29:30]; and
More.

0:00.0	Hey everyone. Welcome to the Drive Podcast. I'm your host Peter Attia. This
0:15.7	podcast, my website, and my weekly newsletter all focus on the goal of
0:19.6	translating the science of longevity into something accessible for everyone.
0:24.0	Our goal is to provide the best content in health and wellness,
0:27.0	and we've established a great team of analysts to make this happen.
0:31.0	It is extremely important to me to provide all of this content without relying
0:34.9	on paid ads. To do this, our work is made entirely possible by our members, and in return,
0:40.3	we offer exclusive member-only content and benefits above and beyond what is available for free.
0:46.0	If you want to take your knowledge of this space to the next level, it's our goal to ensure members get back much more than the price of a subscription.
0:54.0	If you want to learn more about the benefits of our premium membership,
0:58.0	head over to Peter AttiaMD.com
1:01.0	forward slash subscribe. My guest this week is Professor Belinda Beck.
1:07.0	Belinda is a professor of exercise science in the School of Health Science and
1:11.0	social work at Griffith University in Queensland, Australia.
1:14.4	Her research is primarily related to the effects of mechanical loading on bone.
1:19.2	In 2015, she established the bone clinic to roll out this groundbreaking program of research, which we discuss in a lot of detail in this podcast.
1:27.0	She was the principal investigator of the Lift More and Lift More M clinical trials, which demonstrated exercise as therapy for osteoporosis and
1:36.3	low bone mass, something I've discussed a lot on the podcast.
1:39.6	In my conversation with Melinda, we dive into the physiology of bone. It's actually important that you
1:44.7	understand how bone works as a tissue. It's easy to think of it as sort of a
1:50.0	static tissue, but in fact it's quite a reactive tissue. We talk about how the
1:54.7	foundation is set during childhood and how the remodeling over the course of
