When take as directed CBlock will help the following types of carbs from being absorbed into your system: pasta, potatoes, breads, pastries, rice, wheat, oats, wild rice, barley, buckwheat (kasha), rolls, muffins, sweet potatoes, peas corn, beans, and lentils.
It also helps stop carb cravings, which is half the battle. But if you must, with CBlock in your cupboard, you can afford to add a starch or two to your meals occasionally without feeling the guilt of falling off your diet.
