A 26-year-old woman's 88-pound weight loss has gone viral after a Reddit user created a time-lapse GIF that shows the woman's body transformation in just five seconds.
Amanda, who asked that her last name not be used, began taking photos of herself in 2011 as a way to stay on track when she committed to losing weight.
"I knew that I had to start somewhere," Amanda told ABC News. "I figured if I did it [took pictures] at least once a month, at the end of however long it took, I would have this really cool end product."
Amanda started weighing 222 pounds. By eating a high-protein diet, controlling her portions and doing moderate exercise, Amanda lost the 88 pounds in one year and has kept it off.
"I don't think I was actually prepared for the amount of emotional investment," Amanda said. "People bare their souls when they want to take back their health."
"The waist got smaller. The bustline got bigger. The neckline got smaller," Dr. Jen Ashton, ABC News' senior medical contributor, said of Amanda's physical changes.
"But the more significant changes actually occur inside our bodies," she said. "Changes to one's sense of self, to one's physiology [and] to one's internal metabolism."
Last year it was another woman, Julia Kozerski, who made headlines by photographing her dramatic weight loss.
Kozerski, a photographer in Milwaukee, documented each step of her weight-loss journey inside fitting rooms, starting with herself in her wedding gown.
She turned her photographs, taken using a smartphone, into an art project called " Changing Room," where she explored her changing identity as she lost 160 pounds in one year.
"It's unbelievable for me to think about where I am right now and then think about who I was at that time," Kozerski told ABC News last September.
