Mindsip insights from this episode:
Utilize Dutch test for comprehensive hormone analysis in cycling women
For cycling women, a urinary Dutch test is superior to a blood test because it shows how estrogen is being broken down (metabolites), not just the total level.
Disregard flawed study linking time-restricted eating to heart attack risk
A recent study claiming a 91% increased heart attack risk from time-restricted eating was based on unreliable, sloppy data and should not be used to scare people away from the practice.
Manage stress to support progesterone levels
The hormone progesterone, which is dominant the week before a period, is very sensitive to cortisol, so when cortisol from stress goes high, progesterone levels drop.
Vary fasting according to menstrual cycle to balance hormones
Continuously fasting one meal a day can destroy women's hormones; instead, fasting should be varied according to the menstrual cycle to balance estrogen and progesterone.
Reboot dopamine system with a 48-hour fast
Fasting for 48 hours can reboot the dopamine system by creating new receptor sites, allowing you to get more pleasure from less food.
Refeed after fasting to rebuild stronger muscle
While fasting can cause temporary muscle breakdown, the refeeding period is a powerful opportunity to rebuild muscle stronger by consuming at least 30 grams of protein every few hours.
Implement 5-1-1 fasting schedule for optimal health
For men and post-menopausal women, a recommended weekly schedule is five days of intermittent fasting, one day of a longer fast, and one day of feasting with no fasting.
Limit fasting to 15 hours for nursing mothers' health
Nursing mothers should not fast longer than 15 hours because toxins released from cells during autophagy can pass into their breast milk.
