CHUBBY country couple Garth Brooks and Trisha Yearwood are on a giant health kick, vowing to peel off a whopping combined total of 200 pounds this summer, an insider says!

Sources tattle six-foot Garth, a college javelin star, is smashing the scales at over 300 pounds, while his five-foot-eight missus is hitting around 200 — and the weight’s got them down.

“They’re sick and tired of feeling worn out and sluggish all the time,” snitches the insider. “They’ve been avoiding mirrors for years, but they finally had to face the truth.

“They looked at each other and couldn’t lie anymore. It was a case of: ‘You look fat because you ARE fat!’”
