What does “no sugar and no starch” mean?

During Maintenance 1 you need to refrain from eating any foods with sugar or starch, except what occurs naturally in the allowed foods. There are many different names for sugar, so be sure to check the ingredient lists of your favorite foods to determine if they contain sugars or starches. Be warned that there are some vegetables that fall in to this category including: potatoes, peas, and corn.  A list of sugars and starches in all the various forms can be found inside the ThinNow HCG Diet Guide.
