How Sports Nutrition Actually Works With Hanah Mills

·1 hr 20 min·5 clips

Hanah Mills says body composition can decide elite races, but only for athletes paid to compete.

1. The Science of Fitness Podcast episode centers on Hanah Mills and sports nutrition for athletes and active people. 2. Hanah Mills appears as a qualified sports dietitian, and the host frames her as someone who works across body composition, running, and performance. 3. The episode asks what sports nutrition actually looks like when food, training, and body image all collide. 4. Mills explains that sports dietetics covers sweat rate, body composition, disordered eating, REDS, and athlete-specific nutrition. 5. She contrasts that with general dietetics, which she describes as more focused on chronic disease, diabetes, and broader medical settings. 6. A personal-values question leads Mills to food scarcity, starvation, poverty, and more equal distribution of food and money. 7. She connects that answer to obesity, food waste, and the contrast between abundance in some places and starvation in others. 8. Mills says one lesson from the last 12 months has been letting go of hustle culture. 9. She links relentless striving to mental health strain, weaker community connection, and more addictive outlets. 10. The host responds by describing work pressures, small-business stress, and the idea of moving like water. 11. Mills says she has always loved dietetics because she grew up in a health-conscious household with a mother who became a diabetes educator and nurse practitioner. 12. She says private practice lets her build long-term relationships, including clients she has worked with for four or five years. 13. Mills describes her approach as holistic, meeting people where they are on food literacy, money, time, addiction, or overwhelm. 14. She says her own route into dietetics was shaped by runner, rower, and dancer training loads of up to three hours a day as a teenager. 15. She also says hypothalamic amenorrhea and under-fueling caused missing periods, injuries, and disordered eating tendencies in high school. 16. Mills describes body composition as important for elite paid athletes, but not as the first priority for people whose sport is not their job. 17. She uses the analogy of a knee injury and a squat PB to explain why a poor relationship with food should be addressed before a body composition cut. 18. The conversation turns to warning signs such as thinking about food constantly, losing control of intake, and using food in a way that feels like a vice. 19. The tone is conversational interview style, with the host asking broad questions and Mills answering with practical examples and clinical framing. 20. Listeners who want sports nutrition, endurance fueling, and practical dietitian advice will get the most from it, while people wanting entertainment over coaching detail may skip it.
