  • AI coach
  • Food image recognition
  • AI workout planning
  • AI feedback summaries

• Collaboration among dietitians, doctors, and behavioral scientists ensures interventions are effective, safe, and scientifically sound.

Notable Quote:
"Everything that we do is evidence based and you know, there's no fad in sight…we have a nutrition score that takes into consideration calorie density...protein, fiber, unsaturated fats..."

Nutrition and Fertility: Evidence and Advice

[07:20-10:19]

• Nutrition has a powerful influence on fertility for both men and women, reducing conception time.
• The Mediterranean diet is foundational: anti-inflammatory, antioxidant-rich, emphasizing whole grains, colorful vegetables, legumes, nuts/seeds, olive oil, and oily fish; limiting red meat and sugars.
• Fertility nutrition can be highly personalized:
  • Addressing low sperm count: focus on vitamin B12, omega-3, CoQ10, lycopene.
  • Recurrent miscarriage: ensure sufficient vitamin D, B12, folate from both diet and supplements.
  • Encourage adopting pregnancy-supportive diets early, before pregnancy is confirmed.

Notable Quote:
"We know that for both men and women...the right nutrition can improve chances of conception and reduce the time that it takes to get there...where fertility nutrition gets really...exciting and appealing is it can get really specific."

The Future of AI in Personalized Nutrition & Patient Engagement

[10:57-13:09]

• AI coaching and large language models (LLMs) are reshaping personal health support.
• Shift from complex biological personalization (nutrigenomics, microbiome) to practical, accessible AI-based support.
• AI enables 24/7 access to knowledgeable, “human-like” coaches for accountability and behavioral change.
• The next evolution: voice-based AI coaching—users can engage in real-time voice calls, even receive proactive outreach from the AI coach.
• Rapid, recent advances in AI have resulted in significantly more sophisticated, supportive health coaching apps.

Notable Quote:
"What could have a much bigger impact is AI coaching...enabling...24/7 access to a coach that is knowledgeable, that is human like, that can offer support, accountability, and really be there every step of the way."
— Ro Huntriss [11:31]

Notable Moment:
"Very soon we'll be in a place where a user will be able to call the coach and have conversations which will feel...even more human like. And the coach can even call the user at times where they feel an intervention...may be necessary..."
