We're talking about the new trend of using social media to not only document weight loss, but keep you accountable too.
Most of us post pictures online from what we did over the weekend to our vacations.
But for some, posting pictures keeps them motivated enough to drastically change their life.
It's hard to believe the then-and-now pictures of Crystal Moss are of the same person. Since 2004 she's been on a journey, shedding a total of 85 pounds, a journey motivated by health.
"I found out I was close to getting diabetes, so that was the pivotal moment when I realized it's time for a change," said Moss.
There are no pills, no gimmicks, and no tricks.
"It's a lifestyle, it's not just something that you can do for a month and expect to change overnight."
She works on it every day. Encouragement hasn't just come from her family members and friends though; it often comes from complete strangers.
Moss posts her before and after pictures on Instagram, where sometimes users she's never met before, comment on her progress
"You're transformation has me in awe today I start my own journey. And just got truly inspired by your page. Those comments also motivate me to continue going on my path..."
A quick search of tags on Instagram like "progress pic" and "clean eating" reveal thousands like her sharing healthy recipes, a good workout and incredible transformation photos.
Transformation photos are also shared on Facebook, like Peggy Bradford's
Bradford said, "When I went into the dressing room and I was the biggest size I ever was. I was crying in the dressing room and I'm not going to the next step."
Bradford has 4,700 friends to keep her motivated, the majority of whom she doesn't know. After shedding 75 pounds, she started the Facebook group "Steps to Good Health" to help others.
"I know there are a lot of people out there with the same struggles and I didn't want anyone to be going through the journey alone."
On the page, folks share daily accomplishments. Cheerleaders tell them to keep going. "You rock!" they write. "My group in particular is a group where you can go and no one will judge you"
"I would never be able to reach out to these amazing people without this tool," said Bradford.
"All you need is motivation and the drive to do it," said Moss.
