SlimFast’s Keto Products Review – What You Need To Know

Share to save for later!

Back in the day, if you wanted to lose weight, some people would suggest the SlimFast diet. This was before people knew the truth about sugar and how terrible it is for you.

The idea behind the SlimFast diet was that you would lose weight by replacing one premade canned shake for breakfast and one at lunch. Then you would eat a healthy meal for dinner.

The problem with old SlimFast products was that they were full of sugar and other harmful ingredients. You could lose weight simply by reducing your calories alone, but the SlimFast diet was never a good way to sustain weight loss.

Fortunately, even SlimFast has jumped on the keto bandwagon and altered some of their formulas. So, is it safe to use on the ketogenic diet today?

This article talks about the SlimFast diet and whether or not you can use their products on the ketogenic diet.

What is SlimFast?

SlimFast is a company that sells weight loss and nutrition products. It was first launched in 1977 but didn’t become popular in the United States until the 1990s.

Nowadays, people can find their products from major retail stores such as Walmart, Amazon, Jet, Target, Sam’s Club, Walgreens, CVS Pharmacy, and H-E-B.

When the company first came out, they only sold weight loss shakes. These shakes came in a can, and their signature label could be spotted from a mile away. It wasn’t until 2009 that the company started selling low-carb products.

As mentioned above, the SlimFast diet had you drinking a shake for breakfast and lunch, and then eating a low-calorie meal for dinner. Many people lost weight on the SlimFast diet simply because they reduced their calories, but then gained it all back (and then some) when they started eating real food again.

The ironic thing about the SlimFast diet was that its popularity spread like wildfire. Everyone was carrying a SlimFast shake around with them!

The problem with the original SlimFast shakes is that they were full of sugar and canola oil, which is the opposite of what we now know to be healthy.

Here is the nutritional information for a can of the Original French Vanilla SlimFast shake:

  • 180 calories
  • 6 grams of fat
  • 24 grams of carbs
  • 5 grams of fiber
  • 18 grams of sugar
  • 10 grams of protein


Ingredients: fat free milk, water, sugar, canola oil, maltodextrin, milk protein concentrate, cellulose gel, cellulose gum, natural and artificial flavors, mono and diglycerides, potassium phosphate, soy lecithin, calcium phosphate, carrageen, sucralose, acesulfame potassium.

As you can see, the use of sugar, skim milk, acesulfame potassium, sucralose, canola oil and maltodextrin makes this a very low-quality and highly processed food. People eventually caught on to the fact that these shakes aren’t good for you, and SlimFast shake sales suffered as a result.

Today, the company has branched out from its signature sugar-laden shakes with newer formulas that might just put the company back on top of its weight loss game.

Here is a list of product lines that SlimFast now sells:

  • Original (shakes and shake mixes)
  • Advanced nutrition (shakes and smoothie mixes)
  • Advanced energy (shakes and smoothie mixes)
  • Keto (meals, shake mixes, snacks and basics)
  • Diabetic weight loss (shake mixes)
  • Bake shop (cookies and bars)
  • SlimCafe (coffee drinks)
  • Snacks (chips, crisps, and snack bites)
  • Boosters (gummy supplements)

What “Keto” Products Do They Offer?

SlimFast still sells their original shake that made the company popular way back when, but they also sell keto products now for the carb conscious.

In addition to being low in carbs and high in healthy fats, many of the SlimFast keto products feature a wide variety of vitamins and minerals.

Here is a list of keto products offered by SlimFast:

Are These SlimFast Products Strictly Keto-Approved?

Although SlimFast has made definite improvements in their products over the years, we don’t recommend using some of their keto products if you’re a strict die-hard ketogenic dieter.

We give SlimFast props for dropping most of the sugar content in their keto products. Reducing your sugar intake is something you can benefit from regardless of your dietary preferences.

We like the fact that Slimfast MCT Oil is made purely from MCTs in coconut oil. This is their best and most keto-compliant product in our opinion.

However, other SlimFast keto products aren’t the best for strict keto dieters. Perhaps, they might improve their products in the future, but right now, it’s not yet optimal.

First, they use some questionable ingredients in their products that aren’t 100% keto-friendly. Their products also contain more net carbs than most keto dieters would like to see.

Generally, the fewer ingredients a product has, the better it is for you. The more ingredients with words you can’t pronounce, the less natural it is.

For example, when it comes to protein bars, we like the ingredients in other keto bars such as the ones from Perfect Keto, which includes collagen protein, coconut oil, stevia and not much else.

These protein bars tend to contain 3 grams or fewer of net carbs per bar. They also tend to be higher in good fats to help keep you full.

On the other hand, SlimFast snacks and shakes have a MCT blend that includes palm in many of their products, and their net carbs tend to linger around 4 carbs or more.

Secondly, we also noticed that some of their products include ingredients that aren’t keto-friendly such as tapioca syrup, soy, carrageenan, milk, and dextrose/maltodextrin (derived from corn). Typically, these ingredients are avoided by most strict-keto dieters.

They also contain a great deal of preservatives. Some online reviewers (you can watch on YouTube) even state that their blood sugar levels jump after consuming SlimFast products.

Overall, SlimFast keto products are a good option for general low-carb dieters and general population who just want to eat fewer carbs, but not ideal for hardcore ketogenic dieters who appreciate the product ingredients instead of just the carb count.

How Much Weight Can You Lose In A Week With Slim Fast?

Conclusion

SlimFast is an iconic diet program that became popular in the United States back in the 1990s. The diet consisted of premade shakes only. The program asked you to replace your breakfast and lunch for a shake while eating a healthy, low-calorie meal for dinner.

Many people lost weight on the SlimFast diet simply because they reduced their calories, only to find that the weight came back when they started to eat real food again. Their shakes were full of sugar, canola oil, and cheap ingredients that spiked blood sugar levels and left you as hungry as a lion.

Luckily, SlimFast heard about the keto diet and decided to launch its own line of products. They now offer bars, shakes, and even fat bombs with fewer carbs than their original products.

Despite this great attempt, SlimFast keto products aren’t recommended for diehard ketogenic dieters because they contain many ingredients that are not keto-friendly. They also contain more net carbs than similar products from other keto companies.

We recommend sticking with a high-quality keto company or snacking on keto-approved snacks instead of investing in the SlimFast keto line. However, if your a just low-carb eater and you don’t necessarily care about staying in ketosis, then SlimFast could work for you.

Bottom line: To succeed with keto, you just have to stick to your macros, eat real foods, stay active and keep your electrolytes in check. You should avoid processed foods whenever possible for best result.
