Does fat magnify insulin response to simple carbs?

"Don't eat high-GI carbs together with whey, saturated,
monounsaturated or omega-6 fats. High-GI carbs produce a large glucose
and insulin response. Whey, saturated, monounsaturated and omega-6
fats magnify that insulin response. This results in unstable blood
glucose levels and increased appetite. Virtually all junk foods are a
combination of high-GI carbs and fats. The only time that an insulin
spike is desirable is if you have just finished a workout. That
particular insulin spike is obtained by swallowing whey with glucose
and/or maltodextrin not usually accompanied by fat."

I have always thought that fat (saturated) will blunt the insulin
spike and slow the digestion of carbohydrates. The above statement,
however, says the opposite. Anyone knowledgeable about what mechanism
could be behind this if true?

response but it seems that the type of fat doesn't matter:
The Degree of Fat Saturation Does Not Alter Glycemic, Insulinemic or
Satiety Responses to a Starchy Staple in Healthy Men
Inclusion of fat reduces the glycemic response to a carbohydate meal,
although the effect of different types of fat on glycemic, insulinemic
and satiety responses is unclear. Ten healthy men received 50-g
carbohydrate portions of mashed potato with isoenergetic amounts of
butter (saturated fatty acid), Sunola oil (monounsaturated fatty acid)
or sunflower oil (PUFA) and two 50-g glucose loads on separate days.
Capillary blood was collected at regular intervals for 2 h. Satiety
ratings were assessed by use of a rating scale. The glycemic index
(GI), insulin index (II) and satiety index (SI) scores were
calculated. Energy intakes from a meal consumed ad libitum at 2 h and
for the remainder of the day were quantified. The GI values ranged
from 68 ± 8 to 74 ± 10 and the II values ranged from 113 ± 10 to 122 ±
17, but there was no effect of fat type. SI scores and subsequent
energy intake did not differ among the test meals. Substitution of
unsaturated fats for saturated fatty acids had no acute benefits on
postprandial glycemia, insulin demand or short-term satiety in young
men.
