Tara Haakonson thought she was healthier than she'd ever been. In her freshman year at the University of Minnesota Duluth, the St. Cloud-area native was doing all the right things. She worked out obsessively, and her diet was heavy on fruits and vegetables. She entirely eschewed processed foods and fast foods. She started out with a goal of 1,200 calories per day, but that decreased to between 900 and 1,000, said Haakonson, now 24. "Now" is seven years later, and she knows that level is "not sustainable. It's not nearly enough to keep your body healthy."
