Here's how to keep soft-serve from sabotaging your diet:
Mix low- and high-cal flavors. At Tasti D-Lite, for example, calories per 4-ounce serving range from 70 (Banana, Coffee Crunch) to 100 (Fluffernutter Fudge, Peanut Butter Mounds).
Sample the new smoothies that are muscling into the market. Cold Stone Creamery's NrGize Tart & Tangy smoothie is only 25 calories per ounce.
Ask your server to weigh your cup for you.
