While Mama June seemed to shed the pounds rather quickly, the transformation didn't happen overnight. The reality star has been working on getting healthy and fit for years, suffering numerous setbacks and facing many obstacles.
While the world was first introduced to Mama June and her daughter, Alana "Honey Boo Boo" Thompson, on the TLC reality series Toddlers in Tiaras, the family was really thrust into the spotlight -- and the public consciousness -- when their spin-off series debuted in the summer of 2012.
The show followed Mama June's day-to-day activities as the mother of Honey Boo Boo and her three sisters -- Lauryn "Pumpkin" Shannon, Jessica "Chubbs" Shannon, and Anna "Chickadee" Shannon -- as well as her relationship with boyfriend Mike "Sugar Bear" Thompson -- who is the father of Honey Boo Boo. The show aired for four seasons before it was cancelled.
Mama June would later cite her split from her longtime boyfriend as the catalyst for her weight loss transformation. Speaking with ET earlier this week, the reality star shared, "I wanted to also show Sugar Bear… He really made me feel like s**t [and] I wanted to show him, 'Hey, I can do [whatever] I want to do'… I wanted to show him, like, I am actually worth it."

December 2015 -- Mama June and Sugar Bear Go to Boot Camp
After Mama June began losing weight, she and Sugar Bear tried reconnecting -- allegedly in an effort to save their relationship -- for the WE tv reality series Marriage Boot Camp: Reality Stars. Their season premiered in December 2015, and after it ended, the pair didn't stay together.
"The reason she got the gastric sleeve was because she hit a plateau -- she couldn't lose any weight," Pumpkin explained. "And then it came to a point where [the trainer] had to step in because she hit another plateau with the gastric sleeve, and wasn't losing any more weight."
