Mindsip insights from this episode:
Understand Alzheimer's as type 3 diabetes linked to glucose dysfunction
Alzheimer's is called type 3 diabetes because it is fundamentally linked to glucose dysfunction and insulin resistance within the brain.
Incorporate Ginkgo, L-Alpha GPC, Phosphatidylserine, and Citicoline to reverse brain fog
Four of the best supplemental ingredients to reverse brain fog are Ginkgo, L-Alpha GPC, Phosphatidylserine, and Citicoline.
Recognize brain fog as a warning sign of mitochondrial breakdown
Brain fog is not laziness or aging but a biological warning sign that your brain's cellular energy system, the mitochondria, is breaking down.
Limit cardio to reduce brain fog
Too much cardio can actually make brain fog worse by raising cortisol, wrecking sleep, and further draining your mitochondria.
Get morning sunlight to stimulate new mitochondria
Getting 5-10 minutes of direct morning sunlight on your skin and eyes within 30 minutes of waking triggers the creation of new, healthy mitochondria.
Trigger mitophagy with 14 to 18-hour fasting
A 14 to 18-hour fast triggers a process called mitophagy, where your body clears out old, damaged mitochondria to make room for new ones.
Choose food wisely to enhance brain function or prevent sabotage
Every bite of food you take is either making your brain sharper or actively sabotaging it by causing inflammation; there is no neutral option.
Nourish your brain to prevent self-digestion of neurotransmitters
When your brain is starved of the 40+ specific nutrients it needs, it starts breaking down its own neurotransmitter pathways to scavenge them.
Choose five-minute REHI workout for superior cardiorespiratory gains
A five-minute workout called REHI, involving two 20-second all-out sprints, provides better cardiorespiratory improvements than a traditional hour-long session.
