I know what fuckin glicemic index is moron!!! and it was a joke... the glicemic index of the food is not the glicemic index of the whole meal... but YES, if you eat just plain carbs all day(like 90% of the population) the G.I will make huge difference, every body knows that 99% of the obesity in the world is caused by high glicemic carbs diet.... in general...
No it's not. It's caused by eating too many calories.
Again, what is GI? What does it say about food?
