"This was my heaviest pre-pregnancy weight, in 2007. I remember feeling just terrible about myself when I saw this picture. At that particular point, I was really unhappy with my lifestyle and my weight," Mara Schiavocampo said. Her book, Thinspired: How I Lost 90 Pounds -- My Plan for Lasting Weight Loss and Self-Acceptance, documents her 90-pound weight loss. It will be released on December 30.

Schiavocampo said this photo was taken while going to an inauguration party with her husband, Tommie Porter, in January 2009.

"With Tyler Perry at the Triumph Awards just a few weeks before giving birth to my daughter in 2011," Schiavocampo said. " I was ready to pop!"

"Changing my diet was the single biggest factor in my weight loss," Schiavocampo said. "Once I got rid of my trigger foods, the rest was easy."

Here, Schiavocampo is on the set of Good Morning America. "I almost always go workout right after the show," she said. 

"At the Thurgood Marshall College Fund Gala last month," Schiavocampo said. "I used to hate showing my arms. Now my shoulders are my favorite body part!"
