Most of the weight a bear is gaining now is fat, but that like most other animals this will affect the taste one way or the other depending on its diet. It also depends on the care of the meat and cooking styles too. To me this the biggest mistake a lot of people make when it comes to hunting. Steve Rinella from the Meat Eater as others have mentioned has excellent resources about bear, bear fat, and game care in general. Google The Meat Eater and he has videos up there and on YouTube.com. Good luck
