What's the name of protein from a rodent?

Yeah, I think "nutria" is what I was thinking of. Not exactly a rat, but close enough :-) Thanks all for the great answers/talk.

Pnoeric, can we hear from you? Is that it?
I figured that the rodent connection was enough to shift the memory, and hormone/protein -- a major difference, but both show up in weight loss protocols.

Leptin might be what pnoeric was thinking of, but it's not "protein from a rodent." We have leptin as well. And while some may be, not humans are rats...

Found it! Leptin (from the Greek word Leptos -- meaning thin)/ Orchestrates the use of fats to help the body: Accelerate fat breakdown, Control appetite and sweet cravings, Promote fat loss, Regulate pituitary and thyroid functions, Influence fat cell size.
That's from the label of a weight loss formula.
It is a hormone, and the rodent connection was that studies done ended with "sleek rats" if memory serves me. It was popular about 10 years ago, and I don't know what the current status is, but there are lots of search results for it.

Sorry - no idea about the word for rodent meat, but to answer aargersi:

Rabbits are not classified as rodents. They're lagomorphs (sp?) - which I shockingly recall from 3rd or 4th grade, when we had a pet bunny in our classroom. (No one ate him. As far as I know ;)

Can't find it! Did come across some nutria recipes though. Rabbit is a rodent too right??

Nutria?
