This is just a rip-off supplement jumping on the keto bandwagon. We don’t like to throw this word around, but having looked at the formula and at what some users have been saying about their experiences with PureFit Keto, we think we have to call it an outright scam. Some people have been massively over-charged by PureFit Keto. Even those users who don’t get over-charged by the company end up with a supplement that is just useless salts. You can’t trigger ketosis by consuming these substances. Only fasting or a diet completely devoid of protein and carbohydrates can trigger ketosis.
Our PureFit Keto Review
PureFit Keto is one of the most popular fat loss supplements in the UK right now. It seemed to come out of nowhere at the start of this year, but it made some serious waves pretty much as soon as it hit the market. Thousands of people are looking for information on PureFit Keto every single month. This is no doubt due to the popularity of the keto fad right now.
We can’t find an official website for this supplement; it seems to just be available on Amazon, eBay, and other third party sites. All the information in this review is taken from these merchant pages.
So what does PureFit Keto claim to do exactly?
The bottle states that PureFit Keto is an “advanced weight loss” supplement. The bottle also lists a couple of benefits that users can supposedly expect from this weight loss supplement:
- Increased energy
- Greater fat loss
As you can probably guess from the name, this product supposedly works by triggering ketosis.
Ketosis is the state in which the body uses ketone bodies for fuel rather than glucose. Humans typically enter this state when they are in a prolonged fast, or they haven’t consumed any protein or carbohydrates for a long time (often over 48 hours).
The ‘keto diet’ and its related fads have very shaky scientific backing. They normally promote weight loss because the keto diet is the first genuine attempt at disciplined diet control people make. But the scientific claims about ketosis spurring weight loss are nonsense. That is for a different article though!
The question we need to answer is, does PureFit Keto really work?
Is PureFit Keto a scam like so many people claim?
Will it cause side effects?
Find out by reading our full PureFit Keto review below. We look at the formula in detail to see if it can really help with fat loss. Have you used PureFit Keto yourself? What did you think? Let us know in the comments!
PureFit Keto Formula
Let’s take a look at the PureFit Keto formula:
This is kind of what we were expecting – a complete rip-off.
PureFit Keto is just three different salts of Beta Hydroxybutyrate, or BHB salts as they’re more commonly known.
There is absolutely no reason to think that consuming these salts will lead to greater fat loss, increased energy, or better athletic performance.
All they will do is cause you digestive problems and potentially hinder your athletic performance.
We’re not just being sceptical about the whole keto fad here. The studies have been done and the jury was unanimous in its verdict – BHB salts do not promote fat loss or athletic performance.
PureFit Keto is a complete rip-off. It will not help you lose fat, it wont give you more energy, and it wont put you into ketosis.
Like all such supplements, PureFit Keto is designed to ride the keto gravy train until people get wise to the fact that it’s a scientifically baseless scam.
Let’s take a closer look at what the science says about these salts.
The Problem With BHB Salts – They Don’t Work!
As mentioned above, PureFit Keto is effectively just various BHB salts.
These are common ingredients in “keto supplements” today; you’ll normally get some BHB bound to a mineral or amino acid. The mineral it is bound to doesn’t matter a great deal. It is just a method of delivery – a way to stabilize the ketone body so it can be utilized.
Yes, BHB is a ketone body.
There are other ketone bodies besides BHB; acetone, and acetoacetate. However, these other ketone bodies degrade rapidly in the body. They are not as stable as BHB, so they are less suitable for supplementation. You can’t really bind them to magnesium, so you can’t dissolve them in water and put them in a capsule.
Many people claim that consuming BHB salts is sufficient to put you into a state of ketosis.
They say that taking them creates a similar state to fasting in the body, and so you’ll quickly start burning your fat stores for fuel.
Sadly, these claims are false.
These claims and others like them have never once been proven by a scientific study.
There is actually no reason to believe that exogenous ketone salts will magically put you into a state where the body burns fat rather than glucose for fuel. The body will just use both until it runs out of BHB, then it will go back to glucose.
The studies that have been carried out on BHB salts attest to their uselessness.
Some recent trials have found that supplementing with BHB doesn’t lead to significantly higher BHB levels in the blood (that is, you just pass most of it straight through).
For example, in this trial, researchers found that consuming 12-24g of BHB salts from “keto drinks” resulted in a 1.0mM increase in blood BHB levels. Hardly a dramatic increase. As other studies have found, the modest elevation in BHB seen from the consumption of “ketone drinks” generally subsides after 8 hours, when levels of BHB fall back to being practically undetectable (source).
Other trials have focused on BHB’s effects on athletes.
As you might expect, these studies have been less than convincing in their results.
One paper suggests that, because it might inhibit glucose breakdown in the liver, consuming exogenous ketones might actually hinder athletic performance (source). After all, if you are going to be doing a long-distance bike ride or a heavy deadlift session, you want to have plenty of glucose to fuel those high-intensity bursts of effort.
So on these fronts, it seems like consuming ketone salts from supplements like PureFit Keto is a complete waste of time.
Not only do they not seem to be readily absorbed, but they don’t seem to be particularly effective at doing what they’re said to do.
But what about fat loss?
Wont these salts at least enhance fat loss?
There is some evidence that ketone salts might actually prevent lipolysis!
Might BHB Inhibit Fat Loss?
We recently read a paper in which researchers raised the possibility that consuming BHB from supplements like PureFit Keto might actually prevent fat breakdown and metabolism for energy.
To put that another way, there is evidence to suggest that BHB stops you burning fat during exercise.
It’s worth quoting the researchers in this paper at length:
A greater reliance on endogenous fat sources for energy provision during prolonged exercise could be hypothesized to spare endogenous glycogen stores, thereby improving performance capacity. However, ketone bodies have also been shown to reduce circulatory FFA availability via inhibiting the lipolytic effect of catecholamines, and/or via stimulation of hyperinsulinemia, which subsequently reduces lipolysis.
So ketone bodies like BHB inhibit one of the main pathways for fatty acid breakdown.
The researchers go on to highlight another way that BHB might inhibit fat loss:
Féry and Balasse reported that the intravenous administration of ketone bodies during exercise attenuated the exercise-mediated increase in circulating FFA and glycerol availability, suggesting that ketone bodies may have suppressed the lipolytic effect of exercise. More recently, β-OHB has been demonstrated to inhibit adipocyte lipolysis in vitro via the nicotinic acid receptor protein upregulated in macrophages by interferon-γ (PUMA-G/HM74a).
Of course, these are just a handful of studies.
But they certainly raise some interesting questions.
Why are proponents of ketone salts so emphatic about their effects when these effects have never been demonstrated in clinical trials?
Why do we never hear about the potential for a reduction in lipolysis resulting from BHB consumption?
These are interesting questions. But one thing is certain to us – it isn’t worth wasting your money on a supplement like PureFit Keto when it is probably a complete waste of time.
PureFit Keto Scamming People?
We have come across multiple reports of PureFit Keto scamming people out of their hard-earned money.
For example, it seems that the company has lied about having certain celebrity endorsements. They claim that Holly Willoughby used the product to lose weight, when she absolutely did not (source).
We’ve also seen reports of customers being aggressively over-charged for their orders (source).
This is not the behaviour of a reputable company.
This is the behaviour of cheap, nasty scammers.
We strongly advise you to think carefully before giving these people any of your hard-earned money…or your card details!
PureFit Keto Side Effects – Is It Safe?
Not only does BHB seem incapable of promoting fat loss, but it also looks highly likely to cause unpleasant side effects.
There are two main points of concern with the PureFit Keto formula.
The most common side effects reported with BHB salts include dizziness, fatigue, stomach cramps, indigestion, shortness of breath, trouble recovering from exercise, and more.
Since these salts seem highly unlikely to give you any benefits whatsoever, we think exposing yourself to these side effects would be unwise. Why take potential pain for no potential reward?
Then there is the much more serious problem of the unknown caffeine dose.
PureFit Keto contains an unknown quantity of caffeine.
With a proprietary blend of 800mg in total size, there is room for a potentially massive dose of caffeine in PureFit Keto.
For all we know, there could be as much as 790mg of caffeine in each serving of PureFit Keto.
We don’t need to tell you what an absurdly dangerous amount of caffeine that would be to consume in a single sitting, or even spread throughout a day. That’s like 10 espressos. The likelihood of an acute overdose with this dose is very high.
Now, we doubt PureFit Keto contains a potentially lethal dose of caffeine.
But the point is, we don’t know for sure.
This is the problem with proprietary blends. PureFit Keto could be hiding their extremely low dose of caffeine. Or they could be trying to mask their ridiculous dose of caffeine (which they see as doing all the heavy lifting of the fat burner).
There’s no way for us to know for sure, and we’re never going to take a manufacturer’s word for it.
We don’t think PureFit Keto is a safe fat burner at all. We do not advise using it. If you do use it and you experience any side effects whatsoever, cease use and seek medical attention right away.
Please keep the following facts in mind while reading our reviews:
- We are not doctors
- This is not medical advice
You need to do your own research carefully and talk to your regular GP before using any fat burners. Everyone has different physiologies, so there is always the potential for unusual interactions, side effects, and so on. Always get proper medical advice from a qualified doctor before using any supplements, especially when they’re a proprietary blend containing a potentially massive dose of caffeine!
PureFit Keto Review Summary – Should You Try It?
We can’t state this clearly enough: we think PureFit Keto is a complete scam.
There is no evidence that consuming BHB salts is sufficient to put you into ketosis. Not proper ketosis anyway.
There is no reason to think that the keto diet produces fat loss. The reason why so many people lose weight doing keto is because it is the first diet that they try. It is also one of the only diets in which portion control isn’t a serious concern. We will explain all of this in a separate article in more detail.
In any case, not only can PureFit Keto not put you into ketosis, but entering ketosis would not help you anyway. Proper ketosis results from starvation, which is what produces the weight loss!
PureFit Keto contains an unknown – potentially massive – quantity of caffeine.
There are reports of people having money stolen by the company.
The company is currently lying about celebrity endorsements.
IT IS A SCAM!
Basically, there isn’t a single reason why we think someone should buy PureFit Keto.
If you’re serious about maximizing fat loss and retaining muscle, opt for a professional, proven fat burner. Get your diet and training right. Don’t fall for these lazy scams or fad diets.
