The Special K Challenge was designed by Kellogg around their Special K breakfast cereal. According to Kellogg, the Special K Challenge will help you lose six pounds or 1 inch in two weeks.

The details of the plan are: eat two Kellogg’s meals for breakfast and lunch and then a healthy dinner. Breakfast can be either 1 cup of Special K cereal with 2/3 cup of skim milk or Special K Waffles with light syrup. Lunch can be the cereal again or the Special K Protein Meal Bar. You are to eat vegetables and fruit throughout the day as snacks and can drink any beverage as normal. You are also allowed two Special K Protein Snack Bars during the day.

The purpose of the diet is to reduce overall calories, which you would certainly do if two of your meals consisted of one cup of cereal. This diet plan is contrary to other plans such as the South Beach Diet or the G.I. Diet, which promote higher levels of proteins than this diet. The Special K Challenge is carbohydrate intensive which helps to put fiber into the diet but may not promote long term satiety or energy.

There is substantial feedback on the Special K Challenge across the internet and it is quite mixed. The majority of posters speak about being hungry all the time while on the diet. This may be due to the reduced protein. Protein makes the body feel fuller longer whereas carbohydrates raise blood glucose levels quickly and give an immediate boost but do not last as long.

The Special K Challenge would also be rather expensive when compared to preparing your own meals at home. The protein bars are similar in price to many competitive products and range from $1.00 to $2.50 per serving.

  • Easy to follow plan.
  • May reduce overall calories and produce short term weight loss.


  • Expensive when compared to homemade food.
  • Does not provide long term guidance for weight management.
  • May not provide sustained energy or satiety.
  • Doesn’t boost the body’s metabolic rate.


While the Special K Challenge may sound like fun, especially with the personalized plan, we feel it lacks substance as a reasonable long term weight reduction plan. Many experts agree that the best weight loss plans include a permanent change in eating habits along with exercise to burn calories and boost the body’s metabolism. There are also many weight loss products on the market today that work in conjunction with better nutritional management to burn fat. We feel that this may be a better solution than the Special K Challenge.

    I was on the special K challenge right before i got pregnant i was working on losing the weight on put on from my 4 year old i was 155lbs when i started the special k and i got down to 139. i followed my meal plans every day and i was never starving on this challenge. i just had a baby and he is 6months old, i am 170lbs right now i am planing on going back on the special k challege to lose weight again. i say the challenge works and will give it 5 stars.

    I am 16 years old and weighed 160 pounds when I started the day before yesterday. I weighed myself today and I now weigh 158 pounds . 😀 ! This diet IS very hard to stick to though if you’re use to eatting whatever you’d like through out the day. I suggest drinking ALOT of water, and lots of fruits and vegetables to keep yourself from feeling hungry. And make sure to not eat past 6:30 !

    This challenge won’t hurt you.It clearly has all things you need to lose weight healthy. I am tired of food ruling my life and something as easy as the challenge will simplify my life. The only change I am going to make is the ceral and small fruit for breakfast if I eat early I will have protein product for morning snack and if I am out I will eat sensibly some small health meal[I don’t need to eat like a cow. If there is a good space before dinner I will have a challenge drink or snack. If I had a nice lunch out I will have a bowl of cereal and fruit for dinner and snack for mid evening. This is a challenge I can live with and I plan to make it my life plan. Thank you.

    well, i’ve been on the diet for 1 wk. i bought all the special k products and have been very careful to follow the diet. i think the recipes are good ones as well as easy to fix. sad to say, i’ve actually gained 3 lbs so far. i went back & reviewed the diet plan carefully, so i’m not sure what the problem is. i don’t have a lot of experience with dieting, but this diet has lots of sugar in it, which is surprising to me. i also work out everyday, so i guess this diet is just not kicking up my metabolism.



    It might just be water weight.

    you can change your menu every day. if you want to eat something on there that has less cal then what they have on your menu you can swap it out. that’s what i did and you dont have to eat all the food if it says sandwhich fruit and something else. just east the sandwhich and see if your full save your fruit for later for an evening snack. i spread out the food that was on my menu and i was never hungry and i only ate enought to fill me up

    I hope you guys actually think next time you try to make a valid argument. You’re supposed to fill up to at least 1200 calories with fruits and veggies alongside the special k products. If you’re only eating those small products, that’s your own stupidity, and not the fault of the diet. Your body only needs 1200 calories a day.



    Well said. It clearly says that you can eat as much fruit and veg as you like throughout the day


  • 11

    This plan (if you follow their meal suggestions) only offers a little over 800 calories. Your body needs around 1500 calories to function. So yeah, you’ll feel hungry. It’s an insane diet.



    I think this diet would work for people that want to lose weight. I lost 8 lbs in 2 days. That’s because I had flu like symptoms and used the bathroom for 2 days straight! Waaaay too much fiber for me!

    lol that is fuuny!!

    not that good to some ple so i did do and im tellin my friends not to do it so dont it can hurt u and u can die



    The Special K Challenge can hurt you and kill you? From what I have heard it has helped lots of people lose unwanted weight. As for hurting you or killing you, so can driving in your car if there is a crazy person driving around you. Maybe it didn’t work well for you but that doesn’t mean that it won’t for someone else or hasn’t for many people already!



    lol….lol….thats the funniest thing i have ever heard!!! i think McDonalds will kill you before special k does lol



    You’re right, so ignore the lols. It’s a starvation diet, just over half what your body needs to function.



    Starvation diet? You’re eating at least 7 times per day while on this diet….just not Burger King or Taco Bell which is part of the reason why we are by far the country with the most obese people…stop reading these posts if you’re against the plan.

    how do I follow the video and work out???????????

    My husband and I started this together. We have either cereal or shake for breakfast and dinner with our regular meal being lunch. This prevents the big meals at the end of the day. This biggest benefit to us is portion control and reduced calories. This plan also gives us the option to switch things around. If we know we are going to dinner with the parents then we flipped and have shakes (or cereal) for lunch. Eating reasonably for your one regular meal and exercise is key. If you can do the little things to cut calories (light bread, 2% cheese and baked chips) you can get yourself to the lower end of the calorie scale. We have found this easier to do during the summer months as we prefer to be outside in the evening either walking or riding bikes which there is more time to do since dinner prep time is drastically cut. We have also switched out the snacks on occasion to the Nabisco (or whatever brand) of 100 calories. Gives you a little more variety while still maintaining the calorie count. Since we have began, we have both noticed fewer cravings of the sweets, require smaller portions for our “main” meal and weight loss. In the first two weeks, he lost 15 pounds while I lost 8. We both feel healthier and have completely embraced watching what we eat.

    i just started the special k challenge last sunday, so it has almost been a week. i love it so far i dont feel like any changes have been made yet but it takes 2 weeks. but i just eat the cereal for breakfast then lunch have a protein shake and snack bar then for dinner il have another protein bar and eat some veggies. but i also allow myself to snack on the multi grain special crackers after lunch. i havent been working out yet but plan to.

    I like the Special K program. For me, I have to have a plan that is simple to follow and food that taste good. With the variety of cereals Special K makes, this program easy. I especially like the snaks that they have (their new strawberry crisp bars are heaven sent and only 100 calories). I have followed the program for over a month now and have lost 14 pounds. But of course I am exercising as well and eating a healthy meal before six pm. My suggestion is that if you are looking for a simple porgram to follow …and you enjoy eating cereal..than you should give this program a try. If you eat the fruit and veggies as they suggest…you will not go hungry.



    I am now on my 4th day of Special K challenge along with the 10lb slimdown workout. I realized that eating the vegetables and fruits with meals and snacks helps with hunger. So far I am happy with the plan.
