The Kellogg's diet, known as the Special K Challenge, is a two-week program that requires participants to replace two meals a day with a Special K product and eat any food for the third meal, reports Mayo Clinic. Participants can also snack on fruits, nuts and Special K snack products throughout the day.Continue Reading
This diet claims participants can lose almost 5 pounds in two weeks, according to Mayo Clinic. Dieters may consume less calories while on this diet since the meals are portion-controlled. It can also make dieting easier since the meal plan is already laid out; however, participants may feel deprived due to the diet's limited options. Since the diet is only two weeks long, it may be difficult to sustain long-term weight loss because the dieter doesn't learn to modify eating habits to encourage weight loss. Regaining the weight after the diet is over is a possibility.
There are no health care experts that associate with this program, and it does not offer any exercise recommendations, notes WebMD. Most Special K products are not whole-grain and are low in fiber and protein. If the third meal of the day is high in calories and fat, it can be counterproductive to the diet, and weight loss is unlikely.Learn more about Diet Plans
