Phone application helps traveler make the right diet calls

Chris Burns downloaded the weight-loss application MyNetDiary ($5 a month) to his iPhone and used it to track calories and lose 32 pounds. "If I'm sitting at a restaurant, I look up my options and keep track of my caloric intake," he says. "It allows me to record my exercise and what I am burning every day, not only going for a run but also walking the dog. It keeps me at a level to meet my target weight loss. To me, weight loss is a matter of simple math. It's how much you are burning and how much you are putting in."
