Ted Naiman 4: METABOLIC FLEXIBILITY cut down by excess carbs & glucose

Low Carb Down Under
Breckenridge, 2017

Metabolic flexibility:
ability to drop your RQ
(respiratory quotient)
if you are eating more fat

If thin & healthy:
-eat fat...
-will drop RQ
-burn more fat

Metabolic flexibility:
ability to drop your RQ
(respiratory quotient)
if you are eating more fat

If thin & healthy:
-if fasting...
-RQ goes down

If poor
metabolic flexiblity...
-eat higher fat:
-store fat

-if fasting
-struggle!

If on a mixed diet...
-eat a bunch of carbs:
-immediately raise
your RQ

glucose completely
controls:
-metabolism
-substrate oxidation

If on a mixed diet...
-eat a lot of fat:
(stick of butter on top)
-not drop RQ
-will store all that butter

"Excess carbs results in:
-carb oxidation
-lower fat oxidation
-increased RQ

"Excess fat results in:
-enhanced fat storage

"That's because
glucose, not fat,
controls oxidation"

Only have tiny, little
carb/glucose reservoir!

Can only have glucose:
-5g in bloodstream
-200g in liver & muscle

when dump in carbs
& glucose...
MUST burn more glucose
(and NOT bodyfat)

Eat enough carbs & fat:
-HAVE to switch metabolism over
and burn more glucose to get rid of it
-then it converts to fat, via de novo lipogenesis...
-to store it as body fat!

If you're good at burning fat:
-epigenetic changes that...
-upregulate your
fat-burning pathways
-will stay good at burning
fat for a period of time

If you're a glucose burner...
-epigenetic changes
upregulate your
glucose burning:
-you stay good at that

Insulin resistance is:
-impaired ability
~of muscle to oxidize fat
~to switch between
glucose & fat
oxidation

"so much carbs & glucose,
you can't burn fat"
