66-year old Christine Hall calls a Starbucks in Dallas, Texas her second home.
Hall says, "losing weight is hard, but I realized I could do it and I found a system that worked."
Her system, she eats all of her meals at Starbucks and its helped her lose nearly 85 pounds in two years. Christine says she lost all of the weight by counting calories.
Starbucks puts nutrition information on thelabels of their packaged foods and that made it easy to keep track of exactly how much she was eating.
She says most people think of fattening desserts at starbucks, "A lot of people look at the top shelf and they think its muffins and fattening things, but look down on the second shelf and there's really healthy choices."
So Christine starts her day with oatmeal and black coffee- 145 calories.
Lunch and dinner, a panini or bistro box- 220 to 460 calories per meal.
Christine says, "To get the protein every now and then, I get the ham and cheese panini and that's 340. If I go for a bike ride, I can come back and even have a brownie."
But registered Dietitian Rebecca Scritchfield says Chrstine may have trouble maintaining her starbucks diet and she warns if Christine isn't careful, she could suffer from malnutrition. "When you follow something that eliminates entire food groups or limits you to one particular restaurant, it's very difficult to be healthy and meet all of your nutrition needs."
But Christine isn't concerned, she says she's feeling better than every.
