378 ‒ Women’s health & performance: how training, nutrition, & hormones interact across life stages

Guest Introduction and Background00:00

Peter Attia hosts Abby, a former collegiate distance runner (3K, 5K, 1500, 800) who loves strength training despite endurance goals. Fell in love with science and research: "the more you know, the more you don't know." Bob Kaplan quote: "the further you get from shore, the deeper the water gets."

800 and 1500 are most painful events; 1500 requires two more laps at similar pace to 800.

Exercise Across Women's Life Cycle01:33

Exercise delays chronic disease onset and improves healthspan/quality of life. Focus on exercise for women from beginning of life cycle.

Osteoporosis as a childhood disease: Women reach genetic peak bone density ~age 19, then maintain it lifelong; menopause erodes it.

Recommendations for 10-Year-Old Girls

• Exercise as play, transitioning to varied types.
• Build early fitness base: easier to maintain over time.
• Literature supports early start.

Menstruation turning point: Girls often leave sports due to body changes, performance differences.

Abby's lab researches menstrual cycle impacts on performance, recovery, bloating, mental health.

No one talked about menstruation when Abby was growing up.

Abby played all sports; grew up with "exercise more and eat less." Running and resistance training empowering as fitness/strength visibly improves.

Lack of education: menstruation healthy; in sports, no period seen as badge of honor; tied to nutrition.
