Its not like it really matters... the carbs will be digested, and cause the insulin spike hours before he saturated fat reaches the bloodstream. If one if worried about elevated an insulin spike while saturated fat is being digested...wouldn't it make more sense to say "don't eat high gi carbs 3-6 hours after eating saturated fat?". Even more to the point...since an insulin spike will cause all unburned calories (regardless of if they fat, or carbs) to be stored as adipose tissue very easily wouldn't it be better to just say do not eat high gi carbs unless one's glycogen stores are depeleted? Just a thought.
