Special K Diet: Cereal for Weight Loss?

Over the last few months there has been a lot of cereal promotion going on. Kelloggs' Special K brand have been promoting their very own Special K Diet Challenge (for a number of years now). Not to be outdone, Kraft have "lose 10 pounds" emblazoned on virtually the entire line of "Post" brand cereals (called Eat 2 Lose 10)

Both cereal "diets" are bold and upfront with their claims: "Lose up to 6 pounds in 2 weeks!" shouts Special K. Is this for real? Is it valid?

The Special K Diet

  • Eat a serving of Kellogg's® Special K®, Special K® Red Berries, Special K® Vanilla Almond, Special K® Fruit & Yogurt or Special K® Low Carb Lifestyle Protein Plus cereal with 2/3 cup skim milk and fruit for two meals a day.
  • Eat your third meal as you normally do.
  • For snacks, choose from fresh fruits and vegetables or a Special K® Bar.
  • Consume beverages as you normally do.


Special K claim that the diet is "based on valid research conducted at leading universities". In typical hard-sell fashion, they fail to provide the reference or provide a link to the "valid research". After some digging, I found the aforementioned study.

Yes - People Lost Weight

It made interesting reading, and effectively backed up some of the claims from Special K. According to my reading, the mean weight loss was less than 2 kg (4.4 pounds) in the 2 week period.

A basic low fat diet

So what's the magic? There is no magic. The women in the study ate less than they normally did. According to the study, the women in the Special K group were eating about 2200 kcals per day. When they started substituting the cereal meals they dropped daily intake by about 640 kcals per day. Furthermore, a lot of those calories were from fat (~39 grams or 351 kcals).

Good or What?

Personally I think incorporating some cereals into your diet can be good - but there are some caveats here: Satiety - From experience, I've noticed that wolfing down a bowl of cereal doesn't always curb the hunger pangs. However having a bit more protein in the mix does keep the pangs at bay. Nutrition - The simple truth is - Special K is better than what most people eat, but it still contains such gems as High Fructose Corn Syrup. Serving for serving, it has less potassium and fiber than oats, and more sugar. Compare here and here.

The Claim

"Lose 6 Pounds in 2 Weeks"

The Interpretation

"If you currently have a poor diet, but substitute it with our cereal - you may lose 4.4 pounds over the first two weeks. You will be probably feel very hungry while restricting your calories, and will may find eating cereal for dinner or lunch to be untenable after a while. Boredom could well set in. History shows that a low-fat, higher-carb diet can work, but in the long run it may backfire".

That said - you could do a lot worse than eating cereal, skim milk, and fruit - it's a lot healthier than the average American meal...

Well, duh...if you replace a cheeseburger and fries with a bowl of cereal, you'll lose weight. Personally, I'd get really really sick of breakfast cereal if I had to eat it all the time. Plus, I think the serving size of cereal is kind of small (that's why I don't do breakfast cereal...I'd eat WAY too much of it for a "serving"). But hey, some people need that kind of structure.

Hi my name is Page Powell.

I've been on Weight Watcher's for 8 years and I learned a lot. I learned to not to think about food all the time.

If you have a specail goal weight, going for it and take it slow ever baby step at a time.

I normally start my day with a fried egg every morning, to get my protein in, and so I can be on the move. On lunch time I normally eat a pb,j sandwich.

If you want lose 20 lbs., break it down to less and so work your way up to goal weight. Good Luck!.

Hello how are you I was wonder if you can tell me what kind of diet you are on and does it really help I was on this diet where I ate six meals a day and that is to much for me I hardly get two meals in sometime

There is a way to eat on a restricted calorie diet, without pills and injections, that will facilitate weight loss. It actually guarantees you lose between 3 and 7 pounds a week.
It is NOT easy, you have to make some sacrifices, but it works so quickly, the results speak for themselves. Check out Ideal Protein if you have the willpower to cut out carbs, dairy, and fats for a little while. They get gradually reintroduced over the 4 step program.
I didn't have much weight to lose, but I was 5'9 and 163lbs, and cut down to 145lbs in 6 weeks. It was doctor regulated (one of my girlfriends just got her physicians diploma), all fat loss, not just dropping water weight. The program focuses a lot on protein, your skin stays tight and cellulite is reduced, if not eliminated.
Like I said, it's not a miracle diet, you HAVE to have a tremendous amount of willpower to stick to each part of the program, but it is so worth it in the end.

Hey Guys...I recently saw a commercial for the Special K challange. I'm 16 and my mom and I are thinking about starting it. Right now, I'm right around 130 pounds, but not very tall, so I look a little packed in. =]
I work out 2 times a week, and am looking for a way to shead a couple pounds, and look healthier.
Do you think the Special K challange will help me?

I read over the study. I didn't see any claims that these diets kept the weight off. Bet they didn't.

A temporary change in what you eat leads to a temporary change in what you weigh.

Since when is Temporary Weight Loss the goal?

Reply
Hales

I agree with you Sandrine. This diet is good for getting weight off, but then it just creeps back on. The best way to get weight off and keep it off is to start eating better, make a permenant lifestyle change, instead of a temporary one.

It's another quick fix fad diet that doesn't lead to longer term lifestyle changes. I love cereal but would personally be sick of it after about 2-3 days!

These cereals so also contain some ingedients that aren't so good so it's not really a healthier option!!!

I had Special K with Red Berries for brunch today and it did a good job of keeping me full until dinner. Of course I ate 3 servings of it in my bowl, but hey, I'm not a child so 1 serving wouldn't have been nearly enough.

I think I'll eat it again tomorrow because the taste is delicious!

I have been on the Special K diet for 3 weeks now, cheating only one day(for my childs birthday), and it is in fact working, FOR ME. On top of the "replace two meals"-you actually get to snack on fruits and veggies, along with Special K Bars(the chocolate drizzle taste like rice crispie treats with chocolate on top) between meals. However, I am not a big soda drinker. I drink mostly water with an occasional splurge of a soda. Special K has definately gotten less boring with their variety of cereals, but you can actually have a whole quater cup more as a serving size with the plain ol' regular version. My ordinary diet day consists of 1 bowl at breakfast and lunch of Special K followed by a banana or an apple, spinach leaves(eaten like chips from a bag) with tomato salsa, and then dinner they say as you would normally do-and that doesn't mean run out and get the big mac with fries. Let me tell you though, I have been low carbin it since I stopped nursing my daughter 7 months ago, and it doesn't compare to the results that the Special K diet has given me. All in all, I truly believe that eating low fat is where its at. But damn, you gotta live a little, too. Don't beat yourself up over anything. It's just not worth it.

But there's sugar in the special K, so where's the benefit ? I go with regular old fashioned oatmeal, filling, no sugar added (sweeten as you like, you're in control), and with soy-milk which is good for us ladies.

It doesn't matter what kind of cereals are you eating, I don't thing that this one's are special(in sense of losing weight).

They aren't natural!
If we want to lose weight, but more important to be healthy, then eat natural cereals without any other ingredients.

Try oatmeal - even is fashionated are still the best.

I lost 50 lbs by substituting a whole wheat cereal for 2-3 evening meals a week over 8 months. Cereal fills me up and keeps hunger pangs away. I also like the taste and actually prefer it at times over other meal options. It works!

There is no such thing as permanent weightloss. If you continue to excersise and eat less fatty foods, than u will keep the weight off. If you change ur diet and exercise habbits, you will gain weight back. It's as simple as that.

Reply
Nic

This is so stupid- every time I see one of these cereal weight loss ads or commercials it makes me irritated.
OF COURSE you're going to lose weight. It has little to do with the cereal- you're eating fewer calories. Once you go back to eating normally, you'll go back to what you used to weigh.
Personally, I think I'd be starving if all I ate for breakfast and lunch was one cup of cereal.

Reply
Stacy

Ummm...yes, you would lose weight eating cereal for two meals a day because it's low in fat unlike some other options for two meals a day. But, this cereal is pretty high in sugar, especially the fruit and yogurt cereal kelloggs has out now. 12 grams in 3/4 of a cup? In my opinion, the weight will go a lot faster if eat regular cornflakes with fresh raspberries (the cereal only has 2 grams of sugar in a cup & 1/4!). Good luck to you all!

Reply
Kerry

Yeah, I've tried the cereal diet-but not with special K, because that cereal never keeps me full and I end up getting shaky later in the day. Oatmeal is best, but it does get a little hard to smell what everybody else is eating at lunchtime. I thought I lost 5 pounds, but which was about 2 days ago--now I weigh all of 5 pounds back, explain that! I'm going crazy--I work out all the time-my knee may have sufferred because of it and I really don't pig out--but I did have that bite of dessert and 1 cookie yesterday---help!

Since you've been working out you're gaining more muscle which weighs more than fat. Don't go by pounds, go by inches and check up on how you're body is toning up. :)

Reply
Hales

Yes, I agree with Maggie. It's not about how much you weigh. I've stopped checking my weight. I'm more concerned with how toned and lean my body is, and how much fat I got off. And here's another idea for losing weight. I'm trying it, and I feel great. Its really simple, and it's something your body does naturally: Metabolism. Just work on your metabolism, get it higher, and then your body will burn fat even when you sleep! Google it, and it will tell you everything you need to know about how to get your metabolism high, because with a high metabolism, you burn more calories even when you just wanna be lazy.And, if you have a high metabolism, you burn more fat than if you just did diet and excersize alone. I know I'm probably blabbering on, but it's a very good, healthy, and PERMANENT way to lose weight. =]

Weighing 114 you definitely do not need to be on a diet in the first place. You should just want to tone up if you weigh that little.

You are better off eating kashi's organic cereals and taking a multivitamin.

For one thing, that special K cereal has all kinds of artificial ingredients and it does have high fructose corn syrup in it. If you want to have cereal with fruit, choose an organic based cereal without the fortifications in it, take a multivitamin, and also take fish oil.

Listen, one person had said this: "I have been on the Special K diet, and allready, I am developing cravings for the cereal. It turns out a common pitfall of this diet: Carb addiction. Quite simply. this two-bowl diet turned into 5 bowls a day, with excessive amounts of milk! Yikes! Also, my blood sugar was horrible, and I was diagnosed with type 2 diabetes, and my blood sugar was fine when I started! And I say, _____ them, and I am going back to my favorite bison sandwich and coconuts, even some brownies. Suprisenly, my diabetes was cured! Oh, how they lie all the time. They say it's saturated fat that caused diabetes, well, it's CARBs that causes diabetes.

Beef cattle stinks. Buffalo and bison rules!"

It's no wander that the MyPyramid is another a fad lie to the american public. And they don't cover people who are 80 or over.

Check your facts

What is wrong with high fructose corn syrup. It's actually very comparable to cane sugar (your plain old sugar). There is no evidence that is has caused any health problems for anyone...ever. As with regular sugar, it is perfectly fine in MODERATION. It's just an advertisement ploy when companies say "NO HIGH-FRUCTOSE CORN SYRUP!!!" They just want you to buy their product. They know that the average consumer will say "Oh man, no high fructose corn syrup?? Awesome!" when in reality you don't even know what it is. They tricked you. Sorry band-wagon jumpers, it's the truth. Y'all are very easily fooled. Pretty much any food is ok (if not important/healthy!!)in moderation including: fats, carbs, sugars, etc. Your body needs a whole mix of things.

I'm doing the post diet. I have changed my diet completely. More fruits and veggies rather than low fat snackcakes and cookies (I always go overboard on these, probably why I gained in the first place). For the most part, the whole grain cereals keep me full. And then I'm allowed a reasonably sized dinner. This is only my third day, but it seems to be working well because I have no desire to cheat.

To me this is not a 'fad' or a quick way to lose weight. Changing the way you are eating now by eating whole grains, fruits, veggies, and lean meats is how everyone should go about losing weight. And I'm finding myself enjoying fruits and veggies a lot more now than I did before.
