Mama June’s new show From Not to Hot premieres tonight, Feb. 24, and we can’t wait to see the weight loss we’ve been hearing so much about!

In several promos for the series, fans see the 37-year-old working out with a trainer and undergoing gastric bypass surgery for the makeover of a lifetime.

And what a transformation it will be! The mother-of-four has dropped from 460 pounds to a size four. “I just watch my portions and cut back on a lot of the carbs,” she recently told Life & Style. “The one thing that I cannot live without is my grapes and cheese.”

Her daughter Pumpkin also revealed that the reality star “got her boobies done” along with getting excess skin removed. “Her stomach started looking gross,” the 17-year-old explained. “It was hanging from where she lost so much weight, and her arms and her chin.”
