Special K

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. Critics of the Special K diet feel that it may leave dieters feeling hungry because of its limited food options and deter people from sticking to the diet. The diet has been criticised for being too low in protein, fiber, vegetables, and fruits. The diet does not include guidance on how to change unhealthy overeating or lack of exercise and their importance to maintaining weight loss. ==Nutrition==
