Fro-yo isn't as virtuous as many dieters think: “Most frozen yogurts' high-sugar, lower-fat content leaves you feeling unsatisfied," says Cynthia Sass, M.P.H., R.D., SHAPE contributing editor and author of S.A.S.S! Yourself Slim: Conquer Cravings, Drop Pounds and Lose Inches. "You may end up polishing off the entire pint—nearly 700 calories!” Instead of diving into a tub of potentially chemical-laden frozen yogurt, Sass recommends satisfying your sweet craving with coconut milk ice cream. The saturated fat is healthy medium chain triglycerides, which will fill you up with a half-cup serving (about 250 calories) so you don't go back for more, Sass says. The benefits don't stop there, though. “Research shows that these fats boost ‘good’ HDL cholesterol, lower ‘bad’ LDL, and help reduce waist circumference," she adds. "And coconut provides antioxidants similar to those in berries, grapes, and dark chocolate.”
