Laura Micetich is a 24-year-old teacher from Tennessee who wasn't exactly living the healthiest lifestyle a few years ago. "I'd struggled with my weight, with my body not letting me do the things I loved, with loving food, with the potential of health issues," Micetich wrote on her very inspiring Instagram account @theirongiantess.
