“Honestly, when I first started losing weight, it was just being more active, being busy with the show and doing more things with Here Comes Honey Boo Boo,” she said.

“I met with this trainer [Natasha Fett] through my manager… Even though she’s 3,000 miles away, she’s still very supportive through everything. I’m just walking through the neighborhood three miles a day, and just keeping up with that and just keeping up with the kids and just kind of being on the go all the time.”
