Getting Healthy! Amber Portwood Reveals 'Hard' New Diet Plan In A 'Teen Mom OG' Clip

Amber Portwood is making a change!

In a sneak peek for Teen Mom OG, the 25-year-old started a new lifestyle change and diet. "The whole goal is to feel good about myself and feel good in general," she explains. "That's probably another reason why I gained half my weight back, because of depression and stuff like that."

Throughout the season, Amber has been open about how she struggled with depression due to her custody battle with her ex, Gary Shirley, over their one daughter, Leah. Now that she purchased a home close to her daughter and custody has been going smoothly, she is starting to get her life back on track.

"I'm never full, which is a common thing actually, where people never feel full, it's mostly a mental thing though," she admitted. Amber's boyfriend, Matt Baier, explained how a couple times in the middle of the night she would get out of bed in her sleep and make her way to the kitchen to eat and wouldn't even remember doing it!

"It's the first day, it's hard, it's hard and I'm hungry!," she admitted.
