don't know about all of Silock's test etc but do the test on yourself
eat until full with a meal without a bunch of cheap(sugar)
note how long before you feel hungry again
next day(or whenever)
eat same meal only add a dessert(candy,donuts ... you know the deal)
note the time before you get hungry again
for me if i have the dessert i will get hungry again in an hour
NO MATTER how much i've eaten for dinner. I keep getting hungry every hour until i resist eating the sugar(dessert). My stomach feels bloated and i know i've eaten enough but i still crave more dessert stuff. It seems like i can even feel it when i sweat after eating a bunch of sugar food, my sweat feels 'sticky'. Same way you can tell when you sweat after drinking the night before.
just sayin'
