Metabolism

[invasion]

So we hear that if one consumes too much refined insulin-spiking carbs, it is very likely that a large portion of it will get stored as fat. 

 

Simple question. If I eat a large amount of a fatty low glycémic index food, like drinking some full fat cream (30% fat), physiologically, what happens after my body has used what it needs at that time? Does the rest get stored as fat? (I'm it does) but how?
