Purefit Keto Review
If you are thinking of making a purchase then stop and read this first.
In this review of Purefit Keto I will explain everything you need to know about this diet supplement.
You have probably read about Purefit Keto and Shark Tank. This product is really being advertised heavily in the USA, UK and Australia and now all over mainland Europe.
Purefit Keto is not a product to invest your weight loss hopes into.
I am just going to list a few bullet points as to what is wrong with this product.
- This supplement has nothing to do with Ketosis
- They have got the science completely wrong
- There are no notable ingredients in it.
- The whole thing just reeks of disappointment
- Complaints, complaints, complaints !!!!
A Little Summary on Keto Dieting
If you have no idea what Keto (Ketogenetic dieting) is then we have a written an über long and detailed article that explains everything you will ever need to know and more. A good place to start is here …It’s long don’t say I haven’t warned you!
I like bacon as much as the next person, but if you try and tell me I shouldn’t eat fruit because it’s full of sugar, I’m going to laugh in your face until one of us collapses.
And my muscles actually contain glycogen, sooooo…
Anyway, my personal feelings about ketogenic dieting is fairly irrelevant.
I fully accept it works for some people – lots of people if this current wave of hype is anything to go by – but it only works for them because they can stick to it…and it’s the sticking to it that helps them lose weight.
That’s because consistent adherence to a calorie deficit is the long term way of losing weight, and achieving your body goals.
You can do it with or without carbohydrates, but if you do it without, and you go full keto, you might be wondering whether there are some keto-friendly supplements out there to help you succeed.
On your subsequent googlage, you could come across PureFit Keto, a website with one aim: to sell you a bottle of pills called Keto – Advanced Weight Loss.
Is it “the easiest way to burn fat”? as the website states. Will you “burn fat faster than ever”?
What Does Purefit Keto Advanced Weight Loss Do?
The pills contain an ingredient called BHB – aka beta-hydroxybutyrate. This is one of the first compounds – ketone bodies – manufactured when the body goes into ketosis due to very low carbohydrate ingestion.
Ketosis is where your body derives energy from fat and not from glucose (from carbs).
BHB can be used as a fuel in the absence of glucose. It can also cross the blood-brain barrier and there have similar effects on cognitive function.
Purefit say that their product can
“put your body into ketosis”.
They even have a menu header you can click, that says “The Proof”.
When you click for “The Proof” the page just scrolls down to a screenshot of a bunch of facebook messages from happy customers. If only that’s all it took to prove something worked…the internet would explode.
Back to what Purefit Keto does for you. Well, they have a section on how it works too. I’ll try and summarize what they are saying:
- Carbs are a bad source of fuel
- Eating carbs makes us store fat because our body burns carbs first (even though it’s a bad source of fuel apparently)
- We feel tired because we eat carbs
…but if you take Purefit Keto:
- You burn stored fat instead of carbs
- Fat is the ideal source of energy, and gives you 225% more energy than carbs
- When you are in ketosis you have energy and mental clarity, the likes of which you have never before experienced
- You will experience very rapid weight loss
So that’s it. You’ll burn fat instead of carbs and you’ll lose weight super quick.
What they don’t tell you
Oh, they neglect to tell you that you will actually mostly eat fat and some protein to stay in ketosis. But I guess they’d say the fat you eat won’t count as long as it’s not carbs (where’s a raised eyebrow emoji when you need it?).
They go on to explain that BHB can cross the blood brain barrier, which is normally a “very tightly regulated interface but because BHB is such a rock star and so hydrophilic, your brain knows to let it in…”
Hydrophilic substances like ketone bodies cannot cross the blood-brain barrier. Ketone bodies need something called a monocarboxylate transporters (MCT) to get into the brain.
So, BHB crosses the blood-brain barrier DESPITE being hydrophilic, not because of it.
Purefit Keto Side Effects and Precautions
I don’t expect there to be any side effects if you take this.
However, considering the amount of information this company has neglected to mention, it’s worth saying that you have to change your lifestyle, and basically remove all but 50 grams of carbs per day, in order to stay in ketosis.
You can’t just dip in and out of ketosis whenever you take a pill. It just doesn’t work like that.
As for weight loss, there is no scientific evidence to support the notion that going ketogenic speeds it up.
The difference in the number of calories you consume versus those you burn throughout the day is what determines whether you lose weight or not.
Eat a calorie surplus of fat and you will put weight on, no matter whether you are avoiding carbs like the plague or not. Eat below maintenance calories and you will lose weight.
It is that simple.
What’s the Verdict – Will Purefit Keto Work?
I’ll say it again: if weight loss is your goal, then you need to eat below your maintenance calories.
Maintenance calories is the quantity of food in terms of energy (kcal) that will keep you at your current weight.
If you eat 2500 calories a day and you burn 2500, then you are at maintenance.
Eat 2000 calories per day and burn 2500, and you are losing weight.
A bottle of these pills might sound awesome, and ketogenic diets might be in vogue again, but it always always always comes down to calories in and calories out.
