In addition to working out and dieting, Mama June went under the knife to get skin from her stomach, neck, back and arms removed.

Mama June's trainer, Kenya Crooks, spoke with Women's Health earlier in the month about he helped her lose all that weight.

"When you decide to lose weight, you have to be a little selfish and focused all the time," Crooks told the magazine. "Mama June is a giver, and it's hard for her to say 'no' sometimes. I had to remind her that this is her time. I had to say, 'You can't be everything to everybody else and be nothing to yourself.' Once she gave herself permission to put herself first, she was fine."

Alana also talked about her mom choosing to stay hidden in order to provide this big reveal.

"It's been really hard for her [to stay hidden], because my mama is not just a person who can stay in the house," Alana told People. "My mama is very outgoing and stubborn. So when she's like, 'Let's go to the grocery store,' we're like, 'You can't, because you have to stay in hiding, you know.'"

The Mama June: From Not to Hot finale airs next Friday at 10 p.m. ET/PT on WE tv.
