As a personal trainer, one of my main challenges working with female clients is finding the right supplements for the specific requirements of women.
So many fat burners have either the wrong ingredients or a dosage that is way too high. That's why I was delighted to see that Leanbean has a formula specifically designed for females.
That prompted us to find 11 volunteers who helped to test Leanbean, and my dietitian did extensive research into the ingredients for this review.
What Is Leanbean?
According to Ultimate Life, LeanBean is a “clinically proven fat burner for women,” containing ingredients and dosages best suited to average women's weight loss.
This has actually been one of our greatest criticisms of fat burner supplements in general, in that they are pretty much always provided in a way that makes them too strong for female athletes.
The results can sometimes be some side effects like upset stomach or jitters from too many fat burner stimulants.
So, we all welcomed the arrival of a workout product designed specifically with women in mind.
I’ll get to the specific ingredients shortly, but the good thing is that it’s based on natural ingredients, This greatly reduces the risk of toxin exposure, and makes it a lot easier to determine if you have any possible allergies.
It’s recommended to take 6 capsules per day: 2 during breakfast, lunch, and dinner, respectively.

What Is Instant Knockout Cut?
Instant Knockout Cut is a fat burner especially designed for bodybuilders and performance athletes.
With that said, there is no reason why this product won’t work for other people to take advantage of the fat loss benefits.
Roar Ambition has designed the Instant Knockout fat burner formula to work at it’s best when combined with a healthy diet and a fitness routine that involves training several days a week.
It should not be mistaken for one of the snake oil products that you sometimes see advertised on social media.
You’ll still have to put in a reasonable amount of effort for it to work.
Very similar to LeanBean, Instant Knockout fat burner is based on natural ingredients that have been scientifically researched to demonstrate they are effective at burning away the flabby stuff.

Our Testing Approach
In our quest to understand the efficacy of Leanbean and Instant Knockout Cut, we enlisted a diverse group of volunteers, both men and women. Given that Leanbean is specifically formulated for women, we focused that research and testing on female participants.
We organized our participants into two balanced groups, ensuring an even mix of genders in each. Over a span of four weeks, both groups diligently followed their respective supplement regimens.
Before embarking on this journey, we meticulously recorded details such as their existing diet, workout habits, body fat percentage, and current weight loss pace to establish a clear starting point.
The feedback was overwhelmingly positive from both factions, with tangible fat loss evident from their body metrics. And the results highlighted that men and women have some good choices to make.
What Ingredients Do Leanbean and Instant Knockout Have in Common?
The common ingredients that Leanbean and Instant Knockout have in common are glucomannan, vitamins B6 & B12, chromium, zinc, piperine, and green coffee bean.
Our testing team has also confirmed that these ingredients helped them increase calorie burn more consistently.
1. Glucomannan
A meta-analysis of 134 studies in Science Direct showed that glucomannan helped overweight and obese adults lose weight [1]. It has been shown to help with appetite suppression and to increase the effectiveness of your digestive system.
2. Vitamins B6 & B12
These vitamins are helpful for both the regulation of metabolic rates as well as combating tiredness. For busy people trying to fit in some extra workouts, this can make a difference.
3. Chromium
One study from The Science of Diabetes Self-Management and Care journal showed that supplementation of 200–1,000 mcg of chromium as chromium picolinate a day could improve blood glucose control [2]. This can contribute to a more balanced blood sugar level and better weight management.
4. Zinc
Generally speaking, zinc is useful for digestive and metabolic processes that involve fat and fatty acids. For men, it also plays a role in testosterone levels.
5. Piperine
You might have noticed this on more supplements lately. Basically, it helps make your digestive system more effective at absorbing micronutrients.
6. Green Coffee Bean
The final common ingredient is green coffee bean. While it contains a small amount of caffeine, it is contained in these products for its antioxidant properties that help remove toxins.
Their Unique Ingredients
While there are quite a few overlapping ingredients, a couple should be highlighted as unique to each fat burner.
Instant Knockout Cut Ingredients
1. Green Tea Extract
I was quite surprised to hear that it can help with fat oxidation [3]. Personally, I hate the flavor of green tea, so it’s great to see some extract in Instant Knockout.
Check this video below to know more about Green Tea Extract.
2. Caffeine Anhydrous
This is possibly one of the big advantages of Instant Knockout as caffeine is one of the more powerful thermogenics.
Just be careful with any coffee you drink during the day to avoid any jitters. Caffeine anhydrous is a much more concentrated form, thus may cause crashes if taken in excess.
I only take this supplement in the morning, and it has delivered great results.
3. Cayenne pepper
Cayenne pepper is a well known thermogenic [4]. By increasing your body temperature slightly, Instant Knockout can help you get rid of some extra fat.
LeanBean Ingredients
There are a few more extra LeanBean ingredients when compared to Instant Knockout.
1. Choline
Being able to release fat cells is only one part of the puzzle, but getting that fat transported and transformed into energy is just as important. Choline is a nutrient that studies have shown to help with this delivery process [5].
Most of our female testers reported that they gained a lot of energy throughout the day.
2. Chloride
This electrolyte plays a role in keeping you hydrated. Your digestion and metabolism can significantly suffer if you don’t maintain an optimum level of hydration.
3. Turmeric
This is a spice that I have been taking for a long time, mainly for its effects on brain functionality and motivation. However, it is also one of the top thermogenics after caffeine.
"Turmeric works as a supportive supplement for improving the body’s health, so it can work to lose weight on its own. It isn’t meant to be used as any kind of overnight gimmick to shed pounds quickly."

4. Garcinia Cambogia
This Asian fruit has become increasingly popular and more commonly stocked in health food stores and even farmers’ markets. The main reason for including it in LeanBean is for its appetite-suppressing properties.
5. Acai Berry
While the true effects of this berry are still not fully understood, there are some early study indications that it can impact metabolic rates [6]. And because it is a completely safe product, there is no real downside to including it.

Do Leanbean and Instant Knockout Have Any Potential Side Effects?
No, both Leanbean and Instant Knockout don’t have any known side effects when they are taken as recommended. This is backed up by the companies' claims (Ultimate Life and Roar Ambition) and the hundreds of website review comments where men and women didn’t report any problems unless there were allergies to some of the ingredients.
Our testing team also confirmed that they didn't experience any negative effects.
That being said, one of the side effects some women might experience when taking the full amount of Instant Knockout is overstimulation as it has quite a lot of caffeine.
This can impact your sleep, so be careful with the dose and timing or opt for a good fat burner without caffeine.
Pricing
From a pricing perspective, LeanBean and Instant Knockout have very similar offers. Each bottle is a months’ supply at a price of $59.
However, there are excellent special offers where you can buy 3 bottles and get a fourth one for free at a price of $185.
One bottle of Leanbean fat burning supplement contains 180 capsules, which is good for one month. We ordered several times during the testing phase and delivery usually took only four days.
Now, as a woman, you could save a bit of money if you purchase Instant Knockout and reduce the daily dosage. This won’t impact your fitness goals too much, but you would need to do some testing to figure out the optimum dose.
I would also recommend that you only purchase these products on their company websites, as that’s the only place you’ll get the money-back guarantee.

Natural vs. Synthetic Ingredients in Fat Burners
Natural ingredients in fat burners, derived from herbs and plant extracts, have been used for centuries for their medicinal properties. They are often perceived as safer and more holistic. Examples include green tea extract and garcinia cambogia.
On the other hand, synthetic compounds are laboratory-made and designed for specific effects, such as increased metabolism. While they can offer potent and targeted results, there's a potential for side effects.
Some individuals prefer natural ingredients, valuing their organic nature and historical use. Others opt for synthetic compounds, seeking rapid and pronounced effects. Ultimately, the choice hinges on personal preferences and health considerations.
Myths and Misconceptions about Fat Burners
One pervasive myth about fat burners is that they're a "magic pill" guaranteeing weight loss without effort. In reality, these supplements are designed to complement a balanced diet and regular exercise, not replace them.
Another misconception is that all fat burners are detrimental to health.
While some products, especially those with unregulated ingredients, can pose risks, many are formulated based on scientific research and are safe when used as directed.
It's essential to consult experts and rely on scientific evidence rather than hearsay. Educated choices, combined with a holistic approach to health, ensure the effective and safe use of fat burners.
Potential Drug Interactions with Fat Burners
Fat burners, while beneficial for many, can interact with certain medications, potentially diminishing their efficacy or exacerbating side effects.
For instance, fat burners containing caffeine might interfere with blood pressure or heart medications [7]. Additionally, those with ingredients like garcinia cambogia could interact with diabetes medications, affecting blood sugar levels.
Some fat burners might also amplify the effects of anticoagulants, posing bleeding risks.
Given these potential interactions, it's paramount to consult with a healthcare professional before introducing any supplement into one's regimen. Their guidance ensures that individuals can safely benefit from fat burners without compromising their overall health.
Making the Right Choice
For men and performance athletes looking to lose weight and get through a cutting phase faster, out of all fat burners, your top pick should be Instant Knockout Cut.
Now, you might wonder how we managed to reach an agreement here at the office in the Instant Knockout vs LeanBean debate.
Basically, it all came down to looking at the fat burner supplements from a gender and goals perspective and analyzing the results provided by our testing team.
Unless you’re a high-performance or professional female athlete, LeanBean is going to be the best option for women. It has the right ingredients in just the right amounts, meaning you need not halve the dosage or worry about inaccurate doses.
But then, which metabolic type are you? Find out if you are a sugar burner or a fat burner type.
