In an exclusive interview with In Touch, reality star Mama June Shannon reflects on her slimmed-down figure and new life, one year after debuting her new body on WE tv reality show, Mama June: From Not to Hot.

She tells In Touch that she feels pressure to maintain her weight. "People think that I'm going to gain the weight back. But hello, I've almost been at this [weight] for a year and a half and I'm not gaining!"

And though she admits she fluctuates — "My current weight is like 165 to 170," she says — she's vowed to never be obese again. "I just try to watch what I eat and exercise when I can. I don't ever want to go back," says the 5-foot-4 mom to Anna, 23, Jessica "Chubbs," 20, Lauryn "Pumpkin," 18, and Alana "Honey Boo Boo," 12. She also says "hell no" to getting more plastic surgery, "I did what I wanted to do and that’s it!"
