Episode notes
Use Dense Liquid Calories After Severe Low Energy States
- After acute low energy availability (illness) prioritize calorie and fluid restoration with dense liquid calories.
- David used Beta Recovery and liquid calories to replenish after a prolonged stomach bug and warned recovery lags despite quick refueling.
Run A Bicarbonate Fatigue Resistance Study
- Test sodium bicarbonate with a fatigue resistance protocol: do 90 minutes at LT1 then a time-to-exhaustion test, comparing bicarb vs control.
- David argued this design targets marathon-relevant endurance and could settle whether bicarb helps beyond ~1 hour.
Low Leptin Needs Context Not Panic
- Leptin is noisy and context-dependent, so single low readings aren't diagnostic.
- Megan noted leptin varies day-to-day with sleep, stress, training and should be interpreted alongside cycles, free T3 and other markers.
