What Are Special K Protein Shakes?

Special K originally began as a breakfast cereal brand, produced by Kellogg’s in the United States.  The cereal was specifically marketed as being low in fat, for those on a weight loss program.

Though they began with cereals and meal bars, the Special K20 Protein Water and Special K Protein Shakes were introduced.

The main goal of the brands “Special K Challenge” was to help a person lose weight at the rate of six pounds in two weeks by eating Special K products during the day.

Special K works to replace meals either with protein meal bars or protein shakes.

The shakes are a convenient and portable way to have breakfast, lunch, or dinner on the go. Containing 15 g of proteins and 5gm of fiber, this creamy and delicious shake satisfies your hunger along with helping you to lose weight.

These meal replacement shakes are available in multiple flavors including milk chocolate, French vanilla, rich chocolate, strawberry, chocolate mocha and vanilla cappuccino.

Meal replacements have been around for decades, so what has research said about their effectiveness in weight loss?

  • Nutrition Journal – According to one study we uncovered, “the meal replacement diet plan evaluated was an effective strategy for producing robust initial weight loss and for achieving improvements in a number of health-related parameters during weight maintenance, including inflammation and oxidative stress, two key factors more recently shown to underlie our most common chronic diseases.”
  • British Journal of Nutrition – Based on additional research, high-protein meal replacements “may lead to significant weight loss and improvement in obesity measures, metabolic, lipid and inflammatory parameters and hepatic transaminases in overweight/obese.”
  • Journal of the American Dietetic Association – There’s even research that shows meal replacements are effectively used by the United States military to help soldiers maintain healthy weight.

Does It Work?

Do Special K Protein Shakes Work?

Special K Protein Shakes for weight loss are actually meal replacements designed to help you shed a few pounds, though you are still getting the nutrients you need to carry out your everyday activities.

When you replace a high-calorie meal with a protein shake, you tend to restrict your calorie intake.

However, some Special K Protein Shake reviews suggest that it might not actually help in losing weight as it does not possess any fat burning qualities.

Special K Protein Shakes do contain fiber to give you a feeling of fullness and satiety during the day. Consumers will receive enough nutrients and vitamins, so one does not feel any kind of weakness or experience malnourishment.

The shakes calorie counts are good for a short-term weight loss, but if you want to maintain your lost weight over a longer period you need to combine the use of shakes with a healthy diet and exercise plan.

For Kids?

Are Special K Protein Shakes Good for Kids?

The American Academy of Pediatrics has reported that protein supplements do not help in strength, muscle development or endurance.

An average child already consumes plenty of protein in their regular diet, so there is no need to give extra protein supplements or protein shakes.

Extra protein if given to children might result in fat being stored instead of building muscle mass. In fact, at times, greater levels of protein may lead to problems like kidney damage and dehydration.

Vs SlimFast

Special K Protein Shakes vs Slim Fast

Special K Protein Shakes and Slim Fast are supposed to be effective for weight loss, as they are both low in calories. For a weight loss program, besides having a low-calorie content, the nutrient content and the ability to keep you full between meals is equally important.

The protein content in both Slim Fast and Special K Protein Shakes is 15g.

Both shakes come in bottles that are convenient to carry, but they have to be refrigerated before consumption.

Vs Protein Bars

Special K Protein Bars vs Special K Protein Shakes

Both protein bars and protein shakes are beneficial in their own way. Deciding which product works best has to do with the user’s individual end goal.

If the main motive for consuming supplements with proteins is to boost the level of amino acids, then protein shakes are the best option. Amino acids help exercise enthusiasts to build muscles and recover after workouts.

If amino acids effectively flow through the bloodstream, the ability to gain strength and muscle mass is also enhanced.

However, one needs to be careful when you are drinking protein shakes. A healthy and well-balanced diet with adequate fruits and vegetables should be taken along with protein shakes, as these shakes alone cannot provide all the required nutrients.

On the other hand, protein bars are great for losing weight without developing a protein deficiency.

Scientific studies have revealed that chewing and munching on solid foods is more effective in controlling hunger then protein shakes or liquid sources of protein.

When it comes to convenience, protein bars definitely have an advantage over protein shakes.

What Users Are Saying

What Users Are Saying

“This is the best tasting protein drink for the money, it would be better if it had more protein in it but then it probably wouldn’t taste as good. I tried another kind with a lot more protein and it was just nasty tasting. So I will stick to the Special K Protein drink.”

“I bought these hoping they would taste like another brand’s product. I was wrong. They were also on sale at the time so that persuaded me to buy these as well. I was disappointed. It has some protein, but there are plenty of other red flags on the nutrition label. If you’re looking for a drink that’s high protein, low everything else.. this isn’t it.”

“The taste is really good, but disappointing in the amount of carbs and sugar, was looking for something with much less sugar 190 calories in 10 ounces 5g fat, 23 g carbs, 5 g fiber, 17 grams sugar, 15 grams protein. Won’t buy again.”

Bottom Line

The Bottom Line on Special K Protein Shakes

Before heading out for your Special K Protein Shakes, here are our final thoughts. We like the price and that we located some favorable customer comments, but we have concerns because the research about protein and fiber doesn’t relate to this product. We’re also a bit skeptical because customers are talking about the high sugar content and poor taste.

If you want to shed those extra pounds, why not try combining a healthy balanced diet and exercise routine with a weight-loss supplement that contains some clinically-tested ingredients?

One of the best programs we’ve seen this year is one called Noom. Human coaching, personalized meal plans, and interactive support groups are just a few of the things this clinically-tested program has to offer.

  • Bella

    I this the right protein shake to gain muscles or it is just to loose weight?

    • Anna (Editor)

      Hello Bella. Special K Protein Shakes has a high sugar content, 18g, so it might not be the best product to lose weight. Also, it only contains 10g of protein, to gain muscle you would need much more protein. If interested in losing weight you should really check out Dietspotlight Burn. It claims to deliver weight-loss results.
