ET sat down with the 38-year-old reality star on Tuesday, ahead of the season two premiere of Mama June: From Not to Hot airing later this month,where she got candid about the struggles she's faced to keep the weight off -- and why she's terrified.
As fans may recall, Mama June shocked the world last March when she revealed her dramatic, 300-pound weight loss on the WE tv series. The mother of four, who used to weigh 460 pounds, was 160 pounds at her thinnest, but says it's been challenging to retain that same number on the scale. Currently, she weighs around 170.
"The holidays do it!" Mama June tells ET's Keltie Knight of her recent weight gain. "I've been very good, it's over a year and a half. If you say gaining 10 pounds in a year and a half is bad, then it is what it is."
"I mean, I honestly have [stuck to it]," she adds. "Just everything going on, medical stuff and everything... I have probably put on two more pounds."
But according to her youngest daughter, Honey Boo Boo (real name: Alana Thompson), who was with us during the interview, that's not entirely true.
"Mama, don't lie," the 12-year-old exclaims. "Where did you gain that weight back?"
Honey Boo Boo continued on, telling ET that she thinks her mother is "less confident" these days.
"Since she's smaller, she's gotten more hate," she reveals. "Everyone's like, 'Oh, she's going to gain the weight back,' or, 'She's not going to stick to what the doctor says, it’ll all just come back on her.' She's gotten a lot more hate than when she was bigger. Everybody is gonna have something to say."
For Mama June, the reason for undergoing the transformation reached far beyond just looks -- she wanted to make a change and live a healthier life. Unfortunately, that didn't exempt her from experiencing a slew of medical scares in 2017.
"I've been through hell and back the last few months. I've been through a lot within the last year. I don't wanna give away too much, but it's been crazy," she teases, telling ET that fans will get a glimpse of those issues during the second season of her show. "There have been some crazy ones, anywhere from being in a hospital a ton of times. It's just crazy."
"You never know what's going to happen," adds Honey Boo Boo, who says it's "really scary" having to take her mom to the hospital. "You never know if you're going to get good or bad news. Sometimes it can get overwhelming."
So with all of this going on, why does Mama June and her family feel the need to film?
"Because, honestly, our fans are awesome," she explains. "And a lot of fans relate to what we're going through. I have to say, we're probably the realest reality stars. We're non-scripted. Whatever happens, happens."
WE tv's docuseries, Mama June: From Not To Hot, makes its return for season two on Friday, Jan. 12 at 9 p.m. ET/PT. See a sneak peek of what's to come in the video below!
