Improved Unarmed Attack and Natural Weapons

[thorbwahahahaha]

Does improved unarmed attack benefit a race with natural weapons in any way?

I have a non-monk lizardfolk that i am thinking of going Fist of the Forest, but one of the required feats is Improved Unarmed Strike. At first glance it seems that taking this feat will not benefit my character in any way.

I've tried looking for an answer for this question but i keep finding ones regarding monk characters, and even then the answers aren't at all clear. From what I can understand though it seems that the answer is no, is there no way other than Homebrewing this so that it requires Improved Natural Attack instead so that it actually benefits my character?

You gain an unarmed strike, which is sometimes treated as a natural weapon, but which does not augment any existing natural weapons.

You can follow your BAB-derived unarmed strike attacks with natural weapon attacks, though, so at least you have that going for you, which is nice.
