All human bodies burn carbohydrates for energy. It’s the natural order of things. The only time this order is disrupted is if the body is starved of carbohydrates for one reason or another.
Should that happen, we have a fantastic backup process in place whereby the body shifts to burning fat for energy instead. This process is called “ketosis.”
And as you can imagine, the notion of burning fat for energy has all kinds of weight loss implications that appeal to all types of people.
Achieving true ketosis though is easier said than done and requires discipline and persistence. Mainly, you need to switch from a carb based diet to one that relies on healthy fats.
Purefit KETO is a supplement that claims to provide you with the fat burning benefits of ketosis without having to make drastic changes to your entire relationship with food.
It sounds great, but as always, you have to be careful to not read too much into marketing headlines.
Does it work? Let’s find out in this review.
What is Purefit KETO?
Purefit KETO is a non-GMO exogenous ketones product formulated to aid you in entering ketosis. It contains natural ingredients including calcium BHB, sodium BHB and magnesium BHB in each 800mg capsule.
Let’s talk about the ingredients later on and focus on what the actual claims are.
The company behind this product claims that it will trigger ketosis almost instantly. The result is supposedly an energy boost and additional fat burning, which is why it has gained so much attention.
Rather than just trust our own test methods, we have spent many days going through online reviews and also engaging with customers from around the world in forums.
As expected, there are some that just didn’t get the results that were promised, but the main underlying issue with those people is that they didn’t make other lifestyle changes along the way.
Does it work like a magic weight loss pill where you can stay on the couch and demolish a bag of chips and eat nothing but fast food? Absolutely not! You still have to change your diet and then use this supplement as a booster.
Let’s look at the ingredients next.
What are the Ingredients?
- Magnesium, Calcium, and Sodium BHB – This weight loss supplement contains magnesium BHB, calcium BHB and sodium BHB in a proprietary blend totaling 800 mg per capsule. Beta-Hydroxybutyrate is one of the first ketone bodies the liver produces when it is in the earliest stages of transitioning to ketosis.
- It’s a powerful compound that can help to metabolize fat into energy for both brain and body, and without it, there would be no ketosis. But while the mechanisms by which BHB is both created and work are well known to science, there is no evidence to suggest that mixing BHB of various types will enhance the fat burning properties of this ketone body. So take the fact that the “proprietary mix” implies there’s something special going on here with a grain of salt but let’s not dismiss the effectiveness of the product itself.

- Magnesium stearate – This is a mostly inert material that is widely used in the pharmaceutical industry as a filler in tablets and capsules. Its presence here does not impact the efficacy of this keto supplement, it basically just holds it all together, as the active ingredient makes up a very small volume.
- Rice flour – Rice flour is high in protein and is generally considered a healthy alternative to gluten heavy wheat flours. Here it’s used mostly as a filler and has no major impact on the effectiveness of the Purefit KETO diet pills, but it’s not a bad thing.
- Silicon dioxide – Silicon dioxide is employed here as an anti-caking agent that prevents the contents of each capsule from clotting together. It is a very common substance used in the pharmaceutical industry and has no effect on digestion or metabolism.
- Gelatin – Gelatin is another benign substance used, in this case, to create the actual capsule. It’s easily digested and plays no role in the effectiveness of the product.
Is Purefit KETO Legitimate?
When we see a lot of hype and million dollar marketing budgets, our alarm bells always go off.
Mostly, the suspicions are confirmed, and many products simply spend more on advertising and ripped models than on actual product research.
But Purefit KETO is a bit different here. Having tested it ourselves, we did get some clear measures that confirm an increase in blood ketone levels.
Keep in mind that this was done while already in full ketosis, but my colleague Jason was able to achieve similar results while on an off-cycle.
So we then engaged with a lot of people in forums and contacted some nutritionists as well to see if we could get a broader opinion that didn’t rely on just our own experience.
It turns out that there are many people that swear by this supplement. And then there are those that didn’t get any results at all. There really seemed to be nothing in between.
The conclusion we made is that those highly negative reviews really were from people who weren’t exercising or dieting and who bought into a false hype that these pills will just shred fat.
We also want to address an issue that has been reported online where some customers were automatically rebilled after their first order. From what we can tell, this was not a problem on the company’s side, as those customers had mistakenly chosen the subscription package available.
Just keep that in mind when you place your order so that you only receive what you’re expecting.
Based on all this research, we do think it’s a legitimate product if you’re willing to put in the extra effort.
How Much Does Purefit KETO Cost?
Now, let’s get into how much the product is priced at.
For the 30-day supply (60 capsules a bottle), Purefit KETO costs $49.99 which is somewhere around the market average.
They also offer discounts for their bigger packages which are the 60-day and 90-day bottles.
There are substantial savings when you order in bulk, and not just on the shipping costs.
Also, once you have placed your first order, you will receive regular special offers. So make sure you check your inbox regularly to take advantage of some savings.
And if you’re not entirely sure whether this is the right option for you, then definitely choose one of the cheaper packages available.
Try and plan this trial period with a switch to a ketogenic meal plan to get the maximum benefits. It’s not some magic pill that will burn fat without putting in some effort, but more on that in the next section.
Is It Really Effective?
As you can see from the ingredients, this diet pill goes all-in on the BHB ketone bodies but does that mean that it is good for people that are trying to get into keto?
Well, we’ve tested the product, and it does seem to be an effective way to get started on ketosis, but much like any other keto product, it’s only as effective as your diet.
So, as good as this product might be in aiding your ketosis, you still have to pair it with a proper low-carb diet, or it won’t be as good for your health.
Our research has also looked at hundreds of online reviews, as well as reached out to a lot of users in fitness and supplement forums. And we noted two things from this.
First, there are a lot of people who successfully used this product by combining it with a proper keto diet and fitness plan. Many people highlight that it did help during the induction phase to reduce fatigue and that it can help to maintain ketosis.
There were also positive reports that it can help to deal with cheat days where you might add a few extra carbs than normal.
Secondly, some people were commenting that they took it for several weeks and they lost no weight. When we dug deeper into those comments, we did see that the majority of those people made no other changes in their lifestyle.
If you’re looking for a magic pill that burns fat while you watch TV, then, unfortunately, we have to tell you that such a pill doesn’t exist. And Purefit doesn’t make such claims either.
Are There Side Effects from Purefit KETO?
It is no secret that the early stages of keto come with quite a few side effects. These are unpleasant, and the experience does mean that a lot of people will struggle with motivation.
The effects that people struggle with the most are brain fog, fatigue, and dizziness. All of these are down to the fact that your body is desperately trying to find a new source of energy.
This process, known as keto induction, will generally last between a few days and a couple of weeks. But there are a few things you can do to reduce those effects.
One of those options you have is to use supplements to create a ketosis-like effect on a temporary basis, which is what Purefit claims to do.
By increasing blood ketone levels while your body is not producing enough of them yet, you can get the energy boost required to feel less tired and have more mental clarity.
Basically, your muscles and brain won’t be starved of energy, which can help you feel better than you otherwise would.
However, before you think that just doubling your dose will get rid of all the keto-flu symptoms, we have to add a word of caution. Exceeding the recommended dose of Purefit can result in some stomach upset and nausea.
BHB salts are generally safe to take, but just like with anything that is good for you, if you overdo it, then some negative things can happen. The message basically is: don’t increase the dose in the hope to get better results.
Has Purefit Keto Ever Been Featured On Shark Tank?
This has turned out to become quite a controversial topic. Basically, some early advertising material for Purefit KETO insinuated that the product had been featured on the TV show Shark Tank and received funding.
That’s quite a bold statement to make, but unfortunately, it’s not true.
We spent several hours going over episode guides on the Shark Tank website, and there is no reference there. But we also found some research on the Better Business Bureau website that confirms this suspicion.
“BBB has confirmed that the images appearing on PureFit KETO’s website were taken from a separate Shank Tank episode that does not mention PureFit KETO. Internal research has been unable to locate any episodes of Shark Tank that featured PureFit KETO.” – Better Business Bureau.
We’ve also tried to locate some of the older marketing material that featured these images, but for good reasons, they have been removed. It’s quite possible that it was just an overzealous designer in the marketing team, but we cannot say for sure.
Our ultimate conclusion is that this misrepresentation has been removed and you should focus on how well the product actually works.
Let’s take a look at some customer reviews to confirm this.
Purefit KETO Results: Before and After
So, we went on a hunt to look for other people that have been getting results from using the product. Here’s one guy that lost a lot of weight from consistently using Purefit KETO.
And another one here talking more about the whole process of the product and how it helps you lose weight faster.
The Bottom Line: Is PureFit KETO the Real Deal?
It seems (more than a little likely) that in the mostly unregulated keto supplement market, the players from competing products are behind much of the scam talk.
Purefit KETO is a product that claims to be delivering dependable weight loss results for quite some time now, and after reading through hundreds of online reviews, we think that it has has some positive effects for a lot of keto dieters.
Again, we’re saying that this product is reasonably effective and can get you the results that you are looking for in the long haul, but it needs to be paired with a good diet and exercise plan.
It’s also notable to say that Purefit KETO offers customers some affordable packages as well as promos from time to time so its worth checking that out.
