Insulin in fat tissue?

[The Barbarian]

 I thought I read somewhere on here that body fat contains insulin and as you burn it it releases that insulin back into the blood and causes a sugar craving,  is  this  true?

And if so does that mean that animal body fat contains insulin too?

I never read something like that. I think it's wrong.
