Maci Bookout Celebrates Gaining Weight

Maci Bookout often gets criticized for her skinny frame, but the Teen Mom has been trying to gain weight ... and finally succeeded!

"ive gained 3 lbs in 3 days!!! yessss! spring break ready :)" she tweeted yesterday.

Maci's been through a lot lately — she broke up with longtime boyfriend Kyle King and her beloved "Papaw" passed away — so it wouldn't be surprising if she hasn't been eating very well.

Still, she's been trying to keep the pounds on (and add a few) by drinking Muscle Milk and eating a lot of protein.

Stay healthy, Maci!
