Woah, baby! Teen Mom star Tyler Baltierra isn't the only cast member to make headlines thanks to his super impressive weight loss transformation. Throughout the years, your favorite reality TV show moms have continued to experience drama after drama — but while the dramatic nature of being a young parent has stayed the same throughout the seasons, one thing that's drastically changed since the start is the moms' bodies.

Though Tyler recently changed his eating habits in favor of a more conscious lifestyle — and dropped 26 pounds in five weeks as a result! — TM fans can't help but also notice the weight loss transformations of his wife Catelynn Lowell and the rest of the famous moms. From Jenelle Evans' bounce-back game (showing off her post-partum bod just two weeks after giving birth to her daughter Ensley) to Kailyn Lowry's mind-blowing transformation, these mamas have seriously put in some work.

As for Jenelle's envy-worthy, post-pregnancy bod, the 26-year-old reality star has been vocal about her path to weight loss. "Sweating and working out is paying off," she tweeted in 2015. Since giving birth to Ensley, Jenelle has also admitted to drinking Flat Tummy Tea and using waist-trainers to achieve her ideal, fit body.

"Don’t get me wrong, I loved being pregnant but it is so nice to be on the snap back!" she told her fans.
