Episode notes
Seamless Health Tracking Will Rise
- Seamless background tracking will collect many health signals and set personal baselines.
- Lara warns we must decide how much data we want and avoid obsessing over it.
Use CGMs Short-Term To Learn Patterns
- Try short-term continuous glucose monitoring for two weeks to learn personal food responses.
- Use insights to change simple habits like meal order, not for long-term diagnosis without clinician input.
Food Logging Still Has Big Limits
- Food logging with photos has improved but still misses hidden ingredients and dressings.
- Accurate diet tracking remains hard because portion and ingredient details are often unknown.
