Episode notes
Female Longevity Requires A Different Lens
- Women require an upstream, terrain-first longevity approach that considers cyclical hormones and life stressors.
- Tailor interventions to where a woman is (pre, peri, postmenopause) rather than copying male protocols.
Metabolic Flexibility Is Foundational
- Metabolic inflexibility underlies much of accelerated biological aging in women.
- Improving fuel use (carbs, fats, ketones) is foundational before fancy epigenetic tweaks.
Eat In The Light Phase For Better Metabolism
- Time eating to the daylight circadian window and stabilise blood sugar with protein-first meals.
- Aim for three nutrient-dense meals in the light phase: protein, healthy fats, complex carbs.
