Haley Smith's wake-up call to lose weight came after seeing her own engagement photos.
Smith has lost 110 pounds and picked up thousands of Instagram followers in the 15 months since those pictures were taken.
"My whole adult life, I have struggled with my weight, but this was my highest," Smith said of her engagement photos, according to CNN. "I had let myself go and didn't even realize how far I had gotten,"
Just before her wedding last week, Smith posted a pair of before-and-after photos to Instagram, showing her transformation since getting a glimpse at her engagement photos, taken in July 2015.
"Sometimes I can't believe the picture on the left was actually me," Smith wrote. "And sometimes I can't believe that the picture on the right is me."
Smith has more than 73,000 Instagram followers and posts regularly about her workout routines and diet habits. She has become an inspiration to many followers, urging them to "Keep pushing, there's always room for improvement and always new goals to crush!"
This week, Smith posted another before-and-after shot online, this time showing her at the time of her engagement and on her wedding day.
"Both were amazing days that were filled with joy, but they are just two completely different people," she wrote.
