With the popularity of the Atkins diet came a realization that you don't necessarily have to give up your favorite foods, said Roberta McDonald, Senior Vice President of Cabot Cheese. Cheddar cheese is a healthy, calcium-rich food that can be a part of any number of weight loss programs. In fact, studies have shown that getting the recommended amount of calcium not only helps you stick to a diet, but also helps keep the weight off. Cabot's award winning cheddars include 50 and 75 percent reduced fat cheddars.
