Purefit Keto (Shark Tank) Review
Its Benefits, Side Effects, and Scam Theory Explained

Purefit Keto Review

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 promises to provide you with the fat burning benefits of ketosis without having to change your entire relationship to food. That's an idea that may also find extremely attractive. But does it work?

What is Purefit Keto?

You may have seen the Shark Tank episode that had many in the diet and nutrition community buzzing some time back. The fact that the makers were able to convince some very reluctant investors that it was viable served to bring a ton of positive publicity to the product which it has ridden ever since to achieve ever-greater market penetration. But just because something is well known doesn’t mean that it works.

So the only relevant question when it comes to this product is not whether you’ve heard of it, it’s this: Is the Purefit Keto scam real? Let’s look at the ingredients.

  • BHB - This 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 able 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 works 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.
  • Magnesium stearate - Magnesium stearate 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 affect the efficacy of this supplement.
  • ​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 impact on the effectiveness of the Purefit Keto diet pills.
  • Silicon dioxide - Silicon dioxide is employed here as an anti-caking agent that prevents the contents of each capsule from clotting together.
  • ​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 It Really Effective?

And that’s it. As you can see, this diet pill goes all-in on the BHB ketone bodies. The problem is, just as there are robust debates about the effectiveness of multivitamins, no one knows for sure just how effective BHB is in supplement form. 800 mg of a known fat burner sure sounds good. But if those ketone bodies just get dissolved in a sea of stomach acid, then they're not much good after all.

Check it out on Amazon to see the content and price, and you'll find plenty of Purefit Keto reviews that claim it’s the best thing since sliced bread. But are those Purefit Keto reviews real or were they written by the office staff of the manufacturer?

What are the Side Effects of Purefit Keto?

All of the fillers used in his product are well known in the industry and have been used safely in many billions of pills and capsules over the years. None will produce any side effects to speak of. Which leaves us with BHB.

As ketosis is our body's natural backup state, one would think that there couldn't be any adverse side effects to this naturally occurring compound. But that's just it. Supplemental BHB is not naturally occurring. You're imposing it on your system from outside. As such there are a few, though relatively minor, side effects that can crop up from time to time in people who use BHB supplements like this one. They are:

  • ​Gastric distress - Essentially that's a 10 dollar way to say "upset stomach." Upset stomachs occur because your stomach and ketone bodies don't have a natural relationship to one another. Naturally occurring ketone bodies brought about by actual ketosis never spend time in the stomach. That said, by sticking to the recommended dosages you should minimize any discomfort in the event distress does occur.
  • Frequent urination and flatulence - BHB can sometimes cause a person to have to urinate more frequently than usual. When that happens, you're going to be at risk for an electrolyte imbalance so be mindful of that. Some people also note that BHB supplements cause them to break wind more often than average. Both of these potential side effects are pretty rare, however, and neither is dangerous.

​​The Bottom Line

It seems more than a little likely that in the mostly unregulated keto supplement market players with interest in promoting competing products are behind much of the scam talk. The fact is that Purefit Keto Shark Tank is not a scam, and it's just not the most reliably effective on the market today. That would be Perfect Keto.

Perfect Keto is a pioneering product that has been delivering dependable weight loss results for several years now and is considered something of the gold standard for many keto fans.

Again, we’re not saying it doesn't work, only that until it proves its effectiveness over the long haul, we'll stick with the known quantity in Perfect Keto.
