Instant Knockout vs Leanbean Fat Burner Review

The interesting thing about these 2 fat burner supplements is that you can only buy both of them online. We werent too sure about what Leanbean was, but weve been assured by readers that its an up-coming female fat burner.

One thing to keep in mind, is that Instant Knockout isnt gender-specific; this is good, as we havent seen one good only for female supplement on the market yet…but this could change.

Anyway, well be comparing both products side-by-side, to help you see which is the better fat burner for yourself. No lies, just honest facts comparing features and ingredients of both supplements.

What Makes Instant Knockout Stand Out:

  • Tone-Up or Shred Abs faster - Sculpt that rock-hard physique or bikini beach figure youve always dreamed about, more efficiently.
  • Dont be tempted by junk food or snacks - Instant Knockout suppresses your appetite between meals so you decrease your calorie intake much easier.
  • Never feel fatigued - Containing sensible dosages of caffeine per capsule, Instant Knockout keeps you energized throughout the day while you cut carbs & calories, without risks of jitters.
  • Improved self-confidence & sex appeal - Boosting the quality of your life is priceless, and youll feel much better knowing youre rocking the body you deserve after losing some pounds.
  • Endorsed by professional fitness models including Alexia Clark - When there are professional athletes backing a certain product, you know that its good. Think about Nike training shoes or Reebok CrossFit clothing, professionals endorse them because they know they are the best on the market (albeit theyll be getting a payday too).
  • 90-day money-back guarantee - Theres no risk when buying Instant Knockout, as you can call upon the money-back guarantee if it doesnt work for you.


  • More expensive than less effective fat burners - everyone knows you have to pay more to get the best makeup or shoes. Well, its the same with supplements.
  • You can only buy from its official website: - but we prefer online shopping anyway, so this wasnt a problem for us personally.

Quick Review

While Instant Knockout doesnt contain any pink packaging, its backed by internally acclaimed fitness model, Alexia Clark (whos also known as The Queen of Workouts). This was enough reason for us to try this fat burner - and were glad we tried it.

After only 2-3 weeks, we started seeing results; of course, we worked our booty-off in the gym and cut our calories too, but everyone knows this is still necessary when taking any fat burner supplement.

This makes Instant Knockout one of the fastest acting fat burners that weve ever tried. And its certainly the most effective that weve tried. But how does it work?

Its scientifically-proven thermogenics, including green tea extract, cayenne pepper powder, green coffee bean extract - as well as glucomannan, which is known for helping suppress appetite - all help Instant Knockout to help melt your body fat, fast.

Ultimately, Instant Knockout has become our favorite fat burner this year after trying countless ineffective products.

Leanbean Fat Burner


Ingredients Rating: 3.5/5
Side Effects:Potentially Some
Effectiveness: 3.5/5
Price Per Box:$59.00

Leanbean Key Features:

  • 6,000mg Green Coffee Bean Extract
  • 60mg Cayenne Pepper Powder
  • Contains Green Tea Extract


  • Glucomannan under-dosed (studies show you need around 1000mg for it to work)
  • Garcinia Cambogia is highly unreliable, in our honest opinion
  • Raspberry Ketones shown to be unreliable
  • Not good value for money, in our honest opinion

Quick Review

Leanbean is a very respectable fat burner, and it could even be one of the best weve seen.

However, weve given it a 3.5 rating because its a female-only fat burner; personally, we prefer fat burners that arent gender specific - because when was the last time green tea only benefited females, right?

Are female only fat burners necessary?

The truth is, theres no reason for most female only products to be aimed only at women. The only positive for females we can think of with Leanbean, is that it doesnt contain any stimulants, so theres no risk of jitters.

However, you wont be at risk from jitters with fat burners containing sensible dosages of Caffeine Anhydrous anyway. And in our honest opinion, a kick in energy levels is essential when cutting our carbs and lowering your calorie intake in order to lose fat.

Under-dosed main ingredients 

Other issues we had with Leanbean include the under-dosed Glucomannan and Green Tea Extract in this fat burner; while Leanbean is priced to compete with other premium product, it doesnt quite offer the same value for money, in our honest opinion.

But one thing that Leanbean offers is a huge dosage of Green Coffee Bean Extract. This can have a positive effect on your blood sugar levels and suppress appetite, but if we had to choose between having a bigger dosage of Green Coffee Bean Extract or Glucomannan, wed go with Glucomannan everytime (our honest opinion).

Overall, Leanbean is a respectable fat burner but its missing that wow factor

In fairness though, we really like how Leanbean has marketed this product, calling their bundles as Bikini Body and really appealing to our desire of looking good on the beach.

Itll only take a few improvements for this fat burner to be one of our favorites for women. And well repeat that this is a very respectable product that deserves a spot on the market.


From looking at Instant Knockout vs Leanbean, its clear to see that both fat burners are very respectable and deserve a place on the market.

However, its clear to see why Instant Knockout is endorsed by countless people; from international fitness model, Alexia Clark to UFC legends such as Diego Sanchez. Its the best fat burner on the market.

In fact, were pretty lucky that Instant Knockout was made available to the public. This fat burner was originally formulated for professional athletes and fitness models, so its no surprise that it works!

Instant Knockout vs Leanbean Fat Burner Final Verdict

Weve used Instant Knockout ourselves, here at Team, and we can confidently recommend this fat burner to all people. Regardless of whether youre a high-level athlete or casual gym-goer.

Again, well give our respects to the fallen Leanbean in this battle of the fat burners; its clearly a good product, but it simply cant compete with the Instant Knockout.

Winner: Instant Knockout

Instant Knockout is the best natural fat burner on the market for:

  • Faster Fat Loss
  • More Energy 
  • Suppressed Appetite
  • Raised Metabolism
