, rather
than liver glycogen.
Once the liver starts getting overloaded, fructose will be metabolized into fat rather
than liver glycogen, which can lead to obesity, the collection of fat around vital organs and insulin resistance.

Although fruits provide many health benefits, if you want to reduce your body fat to less
than 10 %, Alvino recommends eating «only enough fruit to fill your
liver with
glycogen.
Carbs are the body's go - to fuel for workouts lasting less
than 40 minutes, so optimising intensity depends on either ready (just consumed) glucose or
glycogen, which is how glucose is stored in muscles and the
liver.
More glucose
than what the body needs for energy or
glycogen is converted to triglycerides in the
liver and stored as a more permanent energy storage compound — body fat.
Some authorities, including Tim Noakes, an exercise physiologist who has run over 70 marathons, believe that
liver glycogen rather
than muscle
glycogen is the gating factor in marathon performance.
That a diet with Peat - like sugar proportions — roughly 50 % fructose, 50 % glucose — is better
than a diet with PHD - like sugar proportions — 15 % fructose, 8 % galactose, 77 % glucose — at refilling
liver glycogen.
Once
liver glycogen levels begin to drop and exercise continues the body becomes increasingly hypoglycemic (low blood sugar) mainly because blood glucose is depleted faster
than it is replaced by gluconeogenesis.
In healthy human subjects, a 24 hour fast decreases
liver glycogen stores no more
than 57 % and in absence of vigorous exercise does not lead to muscle
glycogen consumption, suggesting that
liver glycogen stores are sufficient after a 24 hour fast to keep blood glucose levels within normal range (73).
But if you're running for longer
than 90 minutes, the sugar in your blood and
liver glycogen become more important because your stored muscle
glycogen gets depleted.
When you take in more glucose
than your body needs, it stores the extra glucose in the
liver and muscles in a form called
glycogen.
My understanding of what Paul says about fructose in the book is that first thing in the morning may be the best time to consume fructose because the
liver's store of
glycogen has been depleted overnight and so the fructose can be stored by the
liver rather
than converted to fat and thereby become toxic.
However, when you cut ingested carbs down to less
than 100g per day something quite interesting happens: the body burns through those consumed carbs first, then turns to the
glycogen stores in the
liver to maintain its basic system functions.
For lean body mass preservation and training recovery I typically recommend no more
than 16 hours daily as
liver glycogen that fuels our brain depletes and will start liberating amino acids from muscle tissue to convert to glucose in the
liver.
So the best part of being more efficient at burning fat is that you maintain more
glycogen (both
liver and muscle) for maintaining blood sugar levels rather
than trying to fuel your aerobic system.
