Mindsip insights from this episode:
Fuel your brain with ketones for optimal energy
The brain prefers ketones over glucose for fuel, obtaining up to 70% of its energy from them even when glucose levels are twice as high.
Utilize Lumen to optimize evening carb intake for fat-burning
A breathalyzer device called Lumen can show a direct correlation between your evening carb intake, meal timing, and your ability to enter fat-burning mode overnight.
Test metabolic flexibility with a 24-hour fast
A metabolically healthy adult should be able to fast for 24 hours without significant effort, and an inability to do so signals metabolic inflexibility.
Recognize skin signs of insulin resistance for better health
Dark, crinkled skin on the neck (acanthosis nigricans) and skin tags are strong external indicators of underlying insulin resistance.
Leverage exogenous ketones despite high insulin levels
Taking exogenous ketones while having high insulin is a "metabolic paradox," but evidence suggests it is not a metabolic problem and can still be beneficial.
Rethink glucose-centric medicine to prevent harm
Modern medicine's focus on glucose is a late marker for disease, and treatments that raise insulin to lower glucose can cause net harm.
Understand fast and slow insulin resistance for better metabolic health
Insulin resistance can be "fast" (from chronically high insulin) or "slow" (from fat cells growing too large), which explains ethnic differences in metabolic health.
Select exogenous ketone supplements with BHB for optimal benefits
When choosing an exogenous ketone supplement, look for beta-hydroxybutyrate (BHB) in its salt or acid form, not alcohol precursors.
Leverage follicular phase for effective fasting
Women may find fasting easier during the follicular phase (first half of the cycle) when they are more insulin-sensitive and fat-burning.
