SlimFast Review


SlimFast may be one of the most recognized names when it comes to weight loss shakes. Since 1987, these shakes have been sold in grocery stores as a way to help people safely lose weight. However, though the brand makes lofty claims about the effectiveness and health benefits of its products, we’re skeptical about whether it truly is a smart dieting choice. This review will examine the hard facts of Slim Fast shakes’ ingredients, including the logic behind concerns with specific ingredients. We’ll also compare the diet shakes to basic nutritional standards to put everything in context. Our goal is to help you understand SlimFast better from a factual standpoint so you can decide whether it’s right for you.

 

SlimFast Nutritional Facts


At first glance, the nutrition label on that back of SlimFast’s bottle sets off a few warning bells. The ingredients list is lengthy and features no fewer than six items we consider controversial and harmful to your health (see the next section for more details!).

Calories

On looking at the nutrition facts, the first thing we noticed was the calorie count. Just one of these little 11-ounce beverages has 190 calories. While this is an OK number for meal replacement shake, when you weigh that number against the other nutritional benefits of the shake, it comes down to a lot of calories for not much benefit. The ratio of those calories that come from fat is high, as is the amount of sodium when compared to other weight loss shakes.

One of the worst aspects of SlimFast’s nutritional panel, though, is the amount of sugar it contains. 18 grams is higher than just about any other healthy weight-loss shake out there. Sugar does not promote weight loss, and so much of it in a product calls into question where that sugar comes from.

Controversial Ingredients

Like we said, the label contains five ingredients and one claim we consider questionable at best.

Maltodextrin is a food additive used as a thickener[i]. While it’s technically “natural” (derived from corn, rice, potato, or wheat starch), it’s an incredible processed ingredient often used together with artificial sweeteners.

“Natural & Artificial Flavor” is a confusing term unregulated by the FDA[ii]. While there may be natural components in these flavorings, they are processed and often contain synthetic ingredients. A “flavor” according to the FDA is an ingredient “whose significant function in food is flavoring rather than nutritional.”[iii] These flavors are generally created from starches and contain chemicals that pose potential harm to our health.

Monoglycerides and diglycerides are also food additives containing high amounts of trans fats, the most unhealthy form of fat we can eat. Even though the FDA requires labeling trans fat content[iv], this rule doesn’t apply to emulsifiers (which is what mono- and diglycerides are). Basically, this means that by using monoglycerides and diglycerides, a food can contain trans fat without the manufacturer having to admit it on their nutrition label.

Sucralose is also known as Splenda. This artificial sweetener is calorie-free, making it popular in diet and weight loss food products. However, it contains dangerous organocholorine compounds the human body cannot detoxify[v]. While the FDA claims the body only absorbs up 27% of these toxins, a Japanese study found that number to be closer to 40%[vi].

Carrageenan is a natural thickening substance that comes from red seaweed. It’s most often used to keep beverages from separating and to make low-fat foods taste better[vii].

Finally, SlimFast’s label claims the product is lactose free, and yet the second ingredient listed is milk protein concentrate. A asterisk at the bottom of their website qualifies this claim by saying their product is “99.8% lactose free.”[viii]

 

Protein Sources (Core Engine)


All of the protein in SlimFast’s diet shakes come from milk protein concentrate (MPC). Derived from milk, MPC is a complete protein made up of casein and whey proteins in similar ratios to regular milk[ix]. The disappointing thing about the protein in SlimFast is how low the number is. There aren’t many shakes advertised as “protein shakes” that have fewer grams of protein per serving than the SlimFast shake. While it at least makes it to the double digits, a good protein shake will have closer to 15 grams per serving. The company does, however, offer an “Advanced” version of the meal replacement shake that contains 20 grams of protein and less sugar at the cost of increasing the amount of fat.

 

Fiber Sources


With 5 grams of fiber, SlimFast has a passable amount that is likely to improve satiety and keep you full. However, this number is low compared to other weight loss shakes available.

 

What Are the Sweeteners?


Sucralose – also called Splenda – is the artificial sweetener used in SlimFast shakes. It’s made by chlorinating regular table sugar, and that process is what makes sucralose so harmful. Since the human body can’t rid itself of all the sucralose it ingests, the sucralose begins to concentrate in the liver, kidney, and gastrointestinal tract[x]. There it sits, collecting, slowly but surely negatively impacting your health.

Aside from the fact it’s made with an artificial sweetener, SlimFast shakes have so much sugar in them it’s hard to view the shakes as healthy. In fact, 18 grams is almost half of the amount of sugar fond in your average can of soda.

 

Who’s Behind SlimFast?


SlimFast began in 1977 as a product under the Thompson Medical Company. Ten years later, the product became a private company that was eventually bought by Unilever and then sold to Kainos Capital in 2014[xi].

 

Side Effects


Sucralose is a cancer-causing carcinogen also known to cause birth defects and immune dysfunction[xii]. Additional studies have shown sucralose to be the culprit of shrinkage in the thymus gland, enlarged liver and kidneys, and a reduced growth rate.

Monoglycerides and diglycerides contain trans fats, which play a role in increasing the risk of serious health issues. Trans fats can be to blame for diseases such as heart disease, stroke, and diabetes. Health concerns like inflammation, obesity, and high cholesterol levels have also been traced back to trans fats[xiii].

Carrageenan has no nutritional value and has been accused of causing inflammation, cancer, and especially gut problems. Our digestive system’s response to carrageenan is similar to the response our bodies have to pathogens like Salmonella[xiv].

 

How to Contact


SlimFast’s website has very little information on it about the company itself. The only way to contact the company seems to be through their social media.

 

Does it Work?


SlimFast’s diet shakes are part of their “2-1-3” plan which advises replacing 2 meals a day with a shake, eating 1 500-calorie meal, and eating 3 100-calorie snacks[xvi]. Sticking closely to this plan means you’ll be eating around 1200 calories a day, which is low enough that you probably will lose weight. However, that’s only if you stick to their “2-1-3” plan.

Using just the shakes by themselves doesn’t seem likely to promote any notable weight loss. Aside from that, the ingredient concerns and lack of more protein and fiber make this shake average at best.

    I have been drinking the Slim Fast shakes for almost 4 weeks with no weight loss. I eat one healthy small meal per day and two Slim Fast shake replacements. Don’t understand why I am not losing weight.

    I do enjoy your meal replacement shakes; however, they are very high in carbs. This makes it unfriendly to carb restricted diets. If you could figure out a way to increase the fiber content of your product it would accomplish several things. 1) Become more inclusive to a high fiber diet. 2) Be more compatible with a low carb diet 3) Would become more flexible with integrating into normal eating habits on a daily basis.

    I put two teaspoons of ground flaxseeds or ground chia seeds into one slim fast for breakfast. As of May 12, 2016 I have lost 26 pounds. I started on 1/11/16. I simply replaced my breakfast. I use chia and flax not only for the omega 3 oils, but chia in particular swells in the stomach. I\’m good for 5 to 6 hours without eating. I really like slim fast and have great results with it. I get little to no exercise due to back surgery and I am still losing weight. I will continue to use this product to lose the 15 pounds I have left to go. Surgery and post menopause put a lot of weight on me. This product has been great as a diet aid.

    This review says 2016 but the comments are dated back as far at 2014….
    I would love it if you could review the SlimFast Advanced Nutrition shakes. Lots of protein, low sugar, no aspartame or Acesulfame potassium/Acesulfame-K. They don’t taste as good as the original slim fast but when you add better stuff and cut out the sugar you’re going to have that.

    I have tried a lot of other natural brands of meal replacement products.. they are very very expensive. I see slim fast have some ingredients that are not probly good for anyone to take in for prolonged periods.. it as well as other meal replacements do not meant to replace “real” food. I find that it really helps to replace one meal a day, until my weight is lost and I feel full for the four hours. I would rather see someone drink this to lose weight for a short period than to continue getting fatter and have more serious health problems. I do recommend anyone who is on a salt free diet or high blood pressure find an alternative product. If you are pretty healthy and just want to lose some weight by replacing a meal or two a day.. then this is great for that… one to three months. I would get off of it for a month or two, then if you need more weight lost then go back on it again for a short time until you reach your goal. It is very tastey and satifying product. The natural drinks have their drawbacks too.. sometimes taste is awful so you don’t stay on your diet, or it costs an arm and a leg to stay on them. If you have the money to buy the natural products and like them.. more power to you.

    I hate the packaging of the new bottles. IT used to be so easy when it was in the cans — just pop the tops and that was it. Now I have to struggle to get the plastic off of the top; then I have to try to get the flip seal off of the top. The plastic bottles are smaller — probably a gimmick by the company to squeeze more money out of the consumers. AND THEN I read the trouble with the ingredients! I think I just had my last Slim Fast. Not worth it.

      Hi Linda, good question. Although we aren’t responsible for any shake advertisements, diet shakes are often used in conjunction with a healthy workout regimen. The amount of protein makes them useful for building muscle!

        Hi Kearsten, thanks for the question. It’s best to consult your physician about the health risks of controversial ingredients in any meal replacement shake that you’re interested in trying. Good luck!

      Hi Stephanie, thanks for voicing your concerns. Various shakes work best for different people. Depending on what your eating habits are, one shake might work better than another, so it’s important to look at the ingredients to see what your body might react badly to. If you have doubts about ingredients, particularly controversial ones, ask your physician.

    This shake tastes great and is super popular and has been around for awhile, so it must be somewhat effective. Unfortunately, I feel like the ingredients used in this product are counter-active to weightloss and therefore I don’t recommend it. Sure, if you want a dessert shake, this may be a good choice for you, but when it comes to actual MEAL REPLACEMENT shakes? This definitely isn’t an option !

    I’ve been using SlimFast for years…since the cans, and now I mix my own shakes. I love it! It’s definitely helped me maintain my weight for years and it’s cool cause it’s super convenient and easy…I just mix myself a shake, pour it in a canister and drink it on my way to work! A lot of the times I’ll make a second one to sip during the day too, and I just change up what I mix it with so I get a little variety. Sometimes I put strawberries, sometimes bananas, I used milk sometimes, or sometimes just ice and water. I’m not gonna lie but there have been times when I’ve been craving a sweet treat and I add a little dollup of low-fat Cool Whip on top. It’s great!

    Ok, I know this shake is targeted more for women, but my sister and girlfriend love it and my mom was even getting into it, and it seemed to be working for them, so I decided to use it as a meal replacement shake. Ok first of all…even adding a bunch of ingredients to bulk it up, I’m still starving right after I finish. And it tastes kinda like a weirdly sweet milkshake. Almost sickeningly sweet. I don’t know how anyone has lost weight on it!

    I love mixing this with skim milk, peanut butter, and a little vanilla Greek yogurt. It tastes super good, sweet, NOT like a diet shake at all! I blend it all together in the blender and it’s awesome! I don’t know if it’s really helping me LOSE much weight, but it IS delicious!
