All excess calories are ultimately converted to body fat.

Okay, but who said that more than 150 grams of carbohydrates is excessive ?
Is there any scientific reference that show that our body consider more
than 150 grams of carbohydrate excessive even though it's only 600
calories?
If I need 2500 calories and I consume 2000 calories of carboidrates, is
this excessive for the body even though it's not excess calories ?
What is the limit between fair amount and excessive amount ? 150 g ?

Thanks
Nicholas

Hello,
Someone here said that the body converts every carbohydrates over 150 grams
to saturated fats
I wonder if this is true and is there's a official scientific reference to
back this up
Someone consuming a normal caloric diet and doing some sport, let's say
2500 calorie daily would have to consume no more than 24% carbohydrates to
avoid an "excess" of carb is that is true
If that is not true does anyone know the actual figure for carb -> sat fat
convertion or wether there's no such a thing as an excess of carbohydrates
only an excess of calories
Maybe the difference is between unrefined and refined high GI carbs where
only the latter in a normocaloric diet are converted to fat

Scanning various web pages it looks like very little carbohydrates in
a normal diet gets converted to fat, and so I don't think that the
conversion is an important source of saturated fat in the body.
Carbohydrates get burned first, so an excess of calories is what
causes a person to gain weight (mostly as fat).

It depends on how many calories you burn. Any excess of calories
consumed over calories burned is converted to fat.

See above.

No. You'll lose weight.

See above. Anything beyond what your body requires in terms of energy
is excessive and will be turned to fat.

Protein Triggers Carbohydrate Conversion To Body Fat

A biochemistry team from the Department of Veterans Affairs and UT
Southwestern Medical Center at Dallas has identified a
glucose-sensitive protein that translates excessively
high-carbohydrate intake into body fat, especially when combined with
a sedentary lifestyle.
"Once upon a time, we thought hormones directed this long-term control
of metabolism. Turns out, diet also plays a major role," said Dr.
Kosaku "Ko" Uyeda, a UT Southwestern professor of biochemistry and
research career scientist at the Dallas Veterans Affairs Medical
Center.

Uyeda and his UT Southwestern colleagues reported in today's issue of
the Proceedings of the National Academy of Sciences that they isolated
the glucose-sensitive protein, dubbed the carbohydrate response
element-binding protein (ChREBP), that triggers the long-term process
of transforming excess dietary carbohydrates into fat.

They used rat livers in their study, but the results are believed to
reflect the human body's functions.

When people eat desserts, pasta, potatoes or other sugar- and
starch-laden foods beyond the body's energy and nutritional needs,
these carbohydrates become a flood of glucose, and the liver converts
the surplus glucose to fat, Uyeda said.

At some point, the glucose reaches a level that signals the
ChRE-binding protein to start a chain-reaction along a series of genes
that, in turn, activate the synthesis of a dozen enzymes that catalyze
the transformation of the excess glucose into fat to be stored in the
body, he said.
