As you might have guessed already, Leanbean is marketed directly for women. It will work exceptionally well on the system of women and help them lose weight excessively fast. Each of the servings contains 3g of fiber. And that fiber is going to play a crucial role in terms of clearing out the body fat.

How We Ranked the Best Fat Burners

Ranking the fat-burning supplements was not easy. All of the available fat burners will claim that they are the best fat burners. But in reality, they are nothing but average thermogenic fat burners. However, when we considered these factors, things became clear as day:

Clinically Proven Ingredients

The right fat burner will contain nothing but proven ingredients. And the proven ingredients will properly signal your body to start burning fat. Green coffee, caffeine, green tea, and common elements are some of the examples of that. These ingredients have gone through a lot of research.

That said, we emphasized the thermogenic burners that had these ingredients. The ones that did not, however, did not make it to our list.

Advertised Benefits

Some manufacturers will market their supplements by stating that they can make you lose weight overnight. If that were possible, people would not have to put that much work into losing weight. Healthy diet plans would not exist!

For that reason, we did not consider the weight loss supplements that were not honest about the health benefits. If it seems too good to be true, it probably is!

Manufacturer’s Reputation

Some manufactures will market their fat burner supplements by stating the benefits that make sense. And, most of them will utilize the right ingredients at the correct dosages. But the case for the reputed manufacturers will not be the same.

They achieve popularity by offering fat burner supplements that can burn fat properly. And to safeguard their reputation, they would generally use nothing but proven ingredients on those thermogenic fat burners. So, we put a higher priority on those.

Transparent Labeling

Even some of the reputed fat burners will not include proper labeling on the packaging. And the people that are new to the marketplace and trying to find something that will help them get the belly fat off will get confused.

Furthermore, some fat burners will purposely hide the name of the ingredients to trick the buyers. Considering all of that, we ranked the fat burners that were transparent about their formula and ingredients higher than the others.

Ease of Consumption

Sticking to a proper diet and exercise plan is not an easy thing. That is why people opt for fat burner supplements. However, if the fat burners make you go through extra hassles, what is the point? Considering that, we only targeted the fat burners that were easy to add to the routine.

Furthermore, we did not bother considering the fat burners requiring you to go through extra steps to prepare it. Thermogenic fat burners should be easy to consume!

Value Proposition

Sticking to a healthy diet and exercise plan is not that easy. However, not all people who plan on losing weight have the money to purchase high-end fat burners. But the good news is that there is no need to spend hundreds per month to get the fat burners that can accelerate fat loss.

Many will come in the budget segment. However, instead of factoring in the price, we considered the value proposition. The ones that had offered a higher value proposition had a higher ranking in our list.

Doctor Backed

There are a couple of fat burners out there those fat loss experts back. When a professional is backing up a product, they are putting their entire career on the line. That is why most doctor-backed products are effective. So, we prioritized those higher than the others.

Money-Back Guarantee

The moneyback guarantee offers a lot of benefits. Firstly, it provides the peace of mind that you can get a complete refund if the fat burners cannot accelerate the fat loss properly. Secondly, it shows that the brand is standing behind its product.

Furthermore, some people looking to accelerate fat loss are sensitive to some ingredients. Caffeine and green coffee, for example, can cause jitters and restless feelings. So, if you face any side effects, for some reason, you can get your money back if the fat burner comes with a guarantee.

Considering all of these reasons, we have emphasized the fat burners that offered this guarantee.

Who Should Take Fat Burners?

Fat burners are not only for people struggling with diet and exercise. People take them for different reasons. Here are some of the reasons that could tell whether the fat burners are for you or not:

  • You plan on losing weight quickly
  • Want to try out a detox or trying to cleanse your body
  • Planning to start a new weight loss program
  • If you are determined to break through the plateau of weight loss
  • Struggling to get lean and losing weight

Some athletes will even take the fat burners to cut off the excess fat without losing any muscle. Others take the supplements to get an extra boost and increase the calorie expenditure rate by increasing the body temperature. No matter what your goal is, the right fat burner can help you with it.

What Does Science Say Regarding Fat Burners

Many believe that the concept of fat burners is a bit outlandish. However, fat burners do have proven results. A good fat burner can help lose weight, raise calorie expenditure by increasing body temperature, and boost metabolism. Let us go through the ingredients that most fat burners utilize, shall we?


It is one of the most studied and popular fat burner supplements. Many studies have shown that the element holds the ability to make the body lose fat. It can raise the metabolism, making the body burn more calories when resting or exercising.

Take this 1980 study, for example. Researchers have found that the weight loss and metabolic rate have increased significantly for the people who took caffeine. The change occurred after three hours of consumption. The researchers even found that the consumption of caffeine increased the fat oxidation rate.

That said, you do not need to flood your body with caffeine. Even one cup a day can help you with weight loss. This Harvard Study proved that drinking four cups of coffee a day is linked with fat loss. They have also found that that amount of caffeine can lower the risk of diabetes.

Green Tea

Green tea, often called the weight loss magic, contains plenty of fat loss components and caffeine. That is why most of the top-rated fat burners will utilize the ingredient. Nonetheless, this 2013 study has found a strong connection between weight loss and green tea.

Over the eight weeks, the study has shown that the element can significantly drop body weight, BMI and neutralize blood pressure. Plenty of doctors recommend taking green tea regularly because it can raise metabolism to up to 12%. Some study even shows that it can reduce cholesterol and belly fat.


Even though the ingredient is not that popular, it is still present on plenty of fat burners. That said, this study tells all about the element. Researchers have found that the component is linked with plenty of powerful weight loss effects. It is rich in antioxidants and can induce thermogenesis, which increases body temperature.


There are a couple of fat burners that contain L-carnitine. It is one of the stimulant-free amino acids that plenty of professional bodybuilders and athletes prefer over caffeine. It has shown strong results in supporting the recovery rate from working out, reducing muscle damage, and supporting the post-workout soreness.

Furthermore, it will not raise the body temperature to a great extent like some of the stimulants. That is why you can find it in most of the famous and athlete favorite fat burners.

Conjugated Linoleic Acid

Otherwise known as CLA, the Conjugated Linoleic Acid is a natural fatty acid similar to omega six acid. CLA is also fat, but it is a fat that can help you burn fat out of the system quickly. And the researchers of this study found that CLA plays a significant role in lowering the mass of overweight people.


Unlike some of the other ingredients that we have gone through, Yohimbine is a plant extract. It comes from the Yohimbe tree. And it is pretty popular among the fat burners available in the market today. One of the studies found that the element led to higher weight loss results.

The Recommended Dosages for Fat Burners

It would be impossible to state a generic dosage that will work for all of the available fat burners. The ingredient list for each is different. Also, not all of the available options will use the elements at the exact dosages. For example, one might recommend taking two pills a day, while the other might recommend one.

That is why it is pretty important to follow the recommended dosages properly instead of following generic advice. Also, do consider that most of the fat burners will contain caffeine. Some might even have it at 300mg, which is like drinking four cups of coffee.

So, if you face any jittering effects or restless feelings after having too much caffeine, we recommend checking caffeine dosages before taking the supplement.

Side Effects of Fat Burners

Usually, some of the fat burners will make you go through a couple of mild side effects. Most of them will be because of the stimulants of the formula. Some of the most common side effects include:

  • Lack of sleep
  • Anxiety
  • Increased blood pressure
  • Mood change
  • Discomfort in terms of digestion
  • Stomach problems
  • Constipation and diarrhea

However, most healthy adults will not face any of these side effects. And to reduce the chances, we urge following the recommended dosages. Also, if you have any medical condition, consult a doctor before taking these supplements.

Frequently Asked Questions About Fat Burner Supplements

Q: Do I need to exercise after taking a weight loss supplement?
