Blake Shelton found a silver lining in his divorce from his country star wife Miranda Lambert ... it did wonders for his waist!

The 'Voice' star was chatting Wednesday with Blair Garner on the "America's Morning Show" when his dramatic weight loss became a topic of conversation.

Shelton says he didn't actively diet or hit the gym ... it's all about the stress of getting unhitched.

So more than half of people who get married should be real thin, right?
