Break-outs, low energy, difficulty losing weight. That's what Kara Goldin had put on the medical form, but the doctor found nothing wrong. "Just continue the diet and exercise."

Eventually, Kara discovered the cause of her problems on her own: she was hooked on diet soda, and after each one, she would pick up a cookie or other sugary snacks. So she dropped the cookie, ditched the diet soda, and switched to plain water. Three weeks later, her energy had returned, the weight was coming off, and her skin was clearing up. The power of switching from diet soda to water was unbelievable, but she worried that she might not stick with it because plain old water was really boring.

Kara started adding a slice of lemon or pineapple to her water or smashing a blackberry into water and letting it sit overnight in the fridge. A small change, but just enough to let her stick to water. One day at a workout class, one of Kara's friends asked her where she bought that water with blackberry in it, and she laughed, but then she wondered why there wasn't something simple and unsweetened in the grocery store.

Kara started researching the beverage industry and set out to create the perfect recipes to help herself and others switch to drinking water, but soon discovered that it wasn't so easy. She believed in the idea but wondered if a big beverage company would be better able to make her idea a reality. Through some friends, she connected with an executive at Coca-Cola and described the concept to him over the phone, thinking if he was excited about it, she might actually just let them take the ball and run with it. But this expert dismissed her idea out of hand, saying, "Sweetie, Americans love sweet."

"Did he just call me 'sweetie!?!'" – Later that day, after she calmed down, Kara realized that the big soda companies had too much invested in sugary drinks even to consider that Americans could enjoy unsweetened drinks, so she decided right then and there that she was going to start a company and prove that America could fall in love with water, flavored without sweeteners or sugars. 15 years later, Hint®water is the fastest-growing flavored water in the country.
