Demi Lovato's Ready-for-2015 Tweet Is the Only Motivation You Need

She has been an advocate of healthy body image

We might be in the heart of the holiday season, but Demi Lovato is already looking ahead to next year!

The "Neon Lights" singer took to Twitter to write about what she is doing to prep for the holidays, and let's just say we're in awe of her fitness route. "Wow... Just killed a 90 minute cycling class... 31 miles!!!! So proud of how strong I've become this year... 2015 WATCH OUT!!!"

Ninety-minute spin?! Our legs are falling off just thinking about it. For all of those people who are making their resolutions to hit the gym in the New Year, this tweet is the only motivation you'll need. Meanwhile, we'll be here snacking on all of the holiday treats.

Lovato has been an advocate for self-confidence since suffering from an eating disorder and addiction. She has been an inspiration to many and continues to be an icon for many women! Just recently the "Really Don't Care" crooner took those words to heart and responded to a Twitter user who called her fat in the best way.

The tweeter randomly wrote, "Shut up fatty don't choke on ur McDonalds!" and Lovato's witty response nailed it. She tweeted back, "But….Big Macs…." along with several hands up emojis. PREACH!

Seriously, you go, girl!

Even though she knows how to handle the haters, she admitted in the January issue of Fitness magazine that she has trouble with her issues every day.

"I almost went back to rehab for my eating disorder last summer," she confessed to the mag. "I was obsessing over food and terrified of it at the same time. Wilmer [Valderrama] noticed and called me out on it, which was a relief."

She continued, "I was done being afraid of food and so tired of overeating and not knowing why I did it. Now I'm on a structured meal plan. I eat four small meals and two snacks a day. It's teaching me portion control."

We're so happy to hear how well she has been doing ever since! Cheers to a happy and healthy Demi Lovato!
