Many carbohydrates have a higher satiety index than beef does, for example. Potatoes and oats are both more filling than a steak.

Legumes are high in carbohydrates and protein and are extremely nutritious and filling.

Sorry, but I very much doubt this - potatoes have a very high glycemic index (sometimes higher than that of straight glucose!), so you will have a blood glucose crash shortly after eating them, causing you to feel hungry.

I have reactive hypoglycemia, and potatoes are something I strongly avoid for this reason (they will cause me to hypo as soon as 30 mins after eating them).

Glycemic index and insulin response are two different things. Both can be measured directly in the blood and aren't a matter of opinion or anecdote.

I was responding to your post about satiety, not insulin response?

Eating potatoes causes your blood sugar to rise rapidly. When it falls, it invokes a feeling of hunger. Blood glucose can be measured directly in the blood, and isn't a matter of opinion or anecdote :P

I was suspicious of the results, so I just downloaded the paper that your link refers to - low and behold, it has this at the end:

"This study was supported by a competitive investigator-initiated grant from the US Potato Board"

Well, what a surprise!
