• Teddi Mellencamp just posted a new before-and-after photo to her Instagram account.
• She points out that she is "hiding" in the "before" photo.
• The Real Housewives star challenged followers to examine what they're hiding in their own lives.

Real Housewives star Teddi Mellencamp is huge on living a healthy lifestyleshes a health and wellness coach when shes not a reality TV star. But she doesnt just practice what she preaches: Shes had her own health and wellness transformation , too.

Teddi, who is founder of life coaching company All In By Teddi, just shared some before and after pics on Instagram, with a poignant message. I was chatting with my @goallinbyteddi girls today and realized something: before we went all in, we were hiding. Hiding behind a pillow, or a purse, or a family member, she wrote. Hiding under a blanket, or sweatshirt strategically placed around our waists. Hiding from the most important reality of all: our happiness.

Teddi said she was surprised at how similar their stories all were. In how instead of taking charge and being our best selves, we were letting our bodies get the best of us, she said. And Im sure there are many more of us out there. So I ask: are you hiding?

The photos feature a slew of before-and-after shots of women, including Teddi. In the "before" shots, the women can be seen shielding their bodies behind kids, partners, and backpacks, while the "after" photos show them posing much more confidently.

Teddi has been really open about her weight-loss journey, including the fact that she overhauled her diet and exercise plan about four years ago. Teddi opened up to Women's Health about how she gained 80 pounds in one year after moving to California and starting a stressful job. She yo-yo dieted for years, but continued to struggle with her weight after she became a mother.

Teddi said she eventually realized she needed to be accountable for what she was eating and doingwhich led her to start documenting her health journey on Instagram

Teddi's put what she learned into her All In by Teddi accountability program, where she helps clients "learn how to balance and live a healthy lifestyle" to reach their goal weight, according to the All In by Teddi website .

While Teddi has clearly lost a lot of weight, she doesnt publicly talk about what she weighs now. I think putting that number out there makes us want to compare and we are all so different, she previously said on Instagram.
