The Special K brand previously advocated the "Special K Challenge. " The goal of this challenge was to help an individual lose six pounds in two weeks; this loss was achieved by eating specific Special K products throughout the day. The diet began with a single serving of any Special K cereal, accompanied with 2/3 cup of skim milk and a side of fruit. The second meal of the diet included either a Special K Protein Meal Bar, Special K Protein Shake, or another serving of Special K cereal with 2/3 cup of skim milk and a side of fruit. The third meal of the day could be consumed normally, without any Special K restrictions. Throughout the day, an individual is allotted two Special K snacking times, eating any of the following specified snacks: Special K Protein Meal Bars, Special K Protein Shakes, Special K Breakfast Shakes, Special K Protein Granola Bars, Special K Crackers, Special K Cracker Chips, or Special K Popcorn. For any additional snack servings, an individual could consume fruits and vegetables. During the challenge, drinks could be consumed normally.
