[Preview] Are all carbs equally bad? Dr. Fung answers
If you give a volunteer
an extra 1000 calories a day of candy and pop
they will develop fatty liver.
So they will gain 2% weight gain,
but a 27% rise in liver mass.
So they gain some weight
but mostly fat in the liver.
-It’s nasty, huh?
Because the fatty liver then
causes insulin resistance,
which then in the long-term will raise
insulin levels over and over again.
So it’s much more of a long-term problem
than gaining the same amount of weight
around your waist.
Exactly, because again you can barely measure
that effect of that 1000 calories a day.
So again human experiment, they overfed
somebody 1000 calories of sugar basically.
So it was like two cans of Coke
and a bag of candy and something else.
So it sounds like a lot,
but it’s actually not a lot of sugar.
Lots of people do that, right?
Lots of people, especially adolescents.
So in only four or five weeks
they developed fatty liver.
That’s insane, right?
So that’s what kids do these days, huh?
They develop fatty liver
all over the place.
But the good news is that
when they went back to their usual diet
again the body weight dropped,
but only like 3% I think,
but the liver fat fell right away.
-So it’s reversible.
