Its ingredients are individually backed by extensive scientific studies which pinpoint weight loss and fat-burning abilities.

PhenQ is made by Wolfson Berg Ltd. in an FDA approved facility, making it generally safe for both men and women to use.  Read more about the benefits, side effects, and dosage of PhenQ here.

Capsimax Powder (8mg)

This is a complex blend of capsicum, piperine, niacin, and caffeine, which collectively may be effective for fat burning. 

Capsicum and piperine or black pepper may have powerful thermogenic effects on the body, which helps increase body temperature and accelerate the fat-burning process. Many studies have researched the benefits of capsicum as a potential weight loss agent for the body.

Chromium Picolinate (80mcg)

This is a product naturally found in meat, vegetables, and whole-grain and may help reduce cravings for sugar-carb food items. 

It may also help your body control blood sugar levels, which means it may help prevent snacking and unnecessary food intake. 

Chromium picolinate may help your body take in as much sugar as required and lessen the cravings, which may help you lose weight effectively and easily.


Found in tea and coffee, caffeine is a stimulant that can help with weight loss by encouraging thermogenesis in the body. It may also increase the breakdown of fat into fatty acids, a process called lipolysis.

The combination of increased body temperature and fat breakdown positively promotes weight loss and lowers BMI.

Nopal (20mg)

Nopal is sourced from the nopal cactus, which is rich in fibre, making it ideal for weight loss as it may allow you to control hunger and food intake. Nopals may prevent fat from being absorbed by the body and are passed through the system through a bowel movement. This, in turn, helps the body flush out water from the tissues and helps to ease water retention.

Nopal is also full of amino acids that help revitalize the body by increasing your energy, which may be beneficial for weight loss. 

L-Carnitine Fumarate (142.5 mg)

L-Carnitine is an amino acid that helps to boost energy in the body, which is achieved by turning stored fat into energy. Both factors may be extremely beneficial for an effective weight loss regime

2. Leanbean – Best Fat Burner for Women

Leanbean is an all-natural fat burner made especially for women. It is a popular supplement that can fit into any lifestyle or weight loss regimen. Its powerful ingredients may help encourage your body to burn calories, speed up fat loss, and achieve your overall health goals.

It is made from natural ingredients that may specifically aid weight loss. This vegan supplement is easy to use, and keeps working all day, starting from when you take it in the morning.

The formula itself was created to reduce cravings, burn calories faster, and boost your overall energy levels.


  • May increase fat burning activities in the body
  • May stop fat from being absorbed and stored away in the body
  • Helps keep you feeling energized during the day, perfect for keeping up with your exercise routines
  • 90 days to get your money back if you’re not happy



  • Green Coffee

Unroasted beans contain a small amount of caffeine but are full of chlorogenic acid, which is an antioxidant that may encourage weight loss. 

The chlorogenic acid present in green coffee initiates insulin to lower in the system, which may improve the metabolism rate and lower how much fat is absorbed during digestion. It may also help burn stored fat without adding extra fat in the body.

  • Konjac Fiber

Glucomannan is a dietary fiber that comes from the Konjac plant. It is a type of fiber that may encourage the stomach to expand, triggering your body to feel full quickly and for a long period of time. 

This may be an effective way to suppress bad cravings when you are bored and overeating during mealtimes. Other fat burners and supplements that contain Glucomannan may cause a bloating and sluggish feeling, but Leanbean’s smaller dosage is kind to the body and may help avoid these side effects.

  • Choline

Choline is an essential nutrient that is synthesized by the liver. Choline is a key component of several bodily functions, such as transporting fatty acids and removing cholesterol from the body.

Generally speaking, our body doesn’t produce enough choline on its own. This means that it’s important to supplement our intake through foods or fat burners. Choline may have several potential benefits for those who are on a diet plan. In various studies, it’s been found that Choline itself may have an impact on normal fat metabolism. 

  • Chromium Picolinate

Chromium is another key ingredient in Leanbean. It is an essential trace mineral, which may contribute to normal metabolism of macronutrients. This is one of the main keys to maintaining a healthy diet.

Recent studies have also found that chromium may have an impact on maintaining normal glucose levels in blood.

Studies have shown chromium picolinate to be more effective in controlling glucose, compared to other forms of chromium. In addition, it was found that chromium picolinate is more bioavailable and, as such, may be better absorbed by the body.

  • Vitamins B6 & B12

These two vitamins, also known as B complex, may play an important role in healthy body weight. More specifically, studies have found it to be essential in helping you achieve normal energy levels & metabolism.

Maintaining a healthy level of Vitamin B is also key to reducing fatigue, ideal for anyone looking to maintain an active & fit lifestyle.

Some research has also found that Vitamin B may support the function of muscles as well as the nervous system.

  • Chloride

Chloride is an electrolyte, which is essential for keeping the body hydrated. This key ingredient, combined with other electrolytes such as potassium, works with the cells in the stomach to create hydrochloric acid.

As such, it’s been found that chloride may contribute towards healthy digestion.

  • Zinc

Zinc is one of the most essential minerals derived from different plant and animal foods. Consuming an adequate amount of zinc may be essential in helping overall immune function as well as reducing inflammation.

When it comes to hitting your fitness goals, zinc may have an impact on the normal metabolism of fats and carbohydrates. Zinc may also have an effect on protein synthesis, one of the bedrocks of supporting healthy muscle.

  • Turmeric

Most fat-burning supplements contain caffeine as the main ingredient. Large doses of caffeine, however, may cause unwelcome side effects for many people.

One healthier alternative to this is turmeric, one of the most commonly used spices in the world.

The best part of turmeric is that it contains an antioxidant known as curcumin, the substance that gives turmeric its rich golden color. There have been many studies on the potential health benefits of curcumin, and the results look promising.

  • Garcinia Cambogia

This is a tropical fruit commonly used as an enhancement to food, leaving you feeling more satisfied. The skin of garcinia cambogia is naturally high in a substance called hydroxycitric acid, which may be beneficial.

Leanbean contains 100 mg of garcinia cambogia per daily serving, which is a healthy dose of this popular ingredient.

  • Acai Berry

The acai berry originates from Central & South America, and has been consumed by Amazonian tribes for many years. It packs a powerful punch and is another key ingredient in Leanbean.

  • Piperine

Piperine is an ingredient derived from black pepper, and is responsible for the taste of pepper. Piperine may have an important role in improving bioavailability. As such, it was added to Leanbean to help the body absorb other nutrients and improve the overall effectiveness of the ingredients in the supplement.

How Effective Is It?

Leanbean is a supplement that may contribute to a successful weight loss regime. It contains a spectrum of key ingredients like Konjac Fiber and Green Coffee that may encourage the body to burn fat along with the calories ingested. This, in turn, may help you maintain a healthy eating pattern as it may reduce the amount of fat being stored away.

Alongside being a fat burner supplement, it utilizes key ingredients like glucomannan to potentially help control hunger and cravings. This is particularly helpful if you tend to snack during the day or overeat during mealtime.

For the supplement to be effective, you should include it as part of your daily routine. Since it was formulated specifically for women, Leanbean may be a tolerable and convenient product to use.

Green tea contains polyphenols, also known as catechins, which may stop your body from absorbing fat. The caffeine found in green tea can stimulate the nervous system and revitalize energy levels. 

  • Caffeine anhydrous (300mg)

This is a potent caffeine concentrate that’s been dehydrated. It stops the functions of the adenosine receptors, which slows the nervous system. This, in turn, keeps you alert and energized, which is beneficial in getting you through any exercise.

  • GTF Chromium (100mcg)

Traces of GTF chromium are included in the supplement, which may improve the body’s insulin activity to regulate blood sugar levels. This, in turn, brings an energy balance. GTF chromium may help the body move glucose, fatty acids, and amino acids to the cells. 

Another benefit of GTF chromium is the activation of producing proteins, which prevent cravings and snacking. This, in turn, may encourage growth hormones in the body, which is perfect if you are toning or building muscle.

  • Cayenne Powder (100mg)

The cayenne spice increases body temperature, which then attempts to cool down and start burning calories. Cayenne contains capsaicin, which may help reduce the fat that’s stored in the body.

Studies also revealed that capsaicin may reduce hunger and function as an appetite suppressant.

Full of chlorogenic acid, this may help lower cholesterol and the amount of fat absorbed by the body. It may help in reducing unwanted belly fat and stopping those annoying sugar cravings.

  • Vitamin B12 (10mcg)

The presence of Vitamin B12 is vital for converting food to energy, as it encourages the cells in the body to create energy. It may also help disintegrate fatty acids and encourage the body to make proteins, which aids muscle building.

  • Vitamin B6 (5mg)

The presence of Vitamin B6 may help initiate the oxidation of fat in the body. It may also help control the intake of carbs and fats, which helps to maintain calories in the body.

  • Zinc (10mg)

Zinc is an important mineral, and with Instant Knockout, it may help suppress appetite and hunger by lowering insulin levels. Being able to curb your appetite may aid in maintaining a healthy BMI and weight.

What to Consider when Choosing the Most Effective Fat Burners?

The industry is saturated with various types of fat burners that claim to be a magic cure to your weight problems. 

However, some factors can help you decide on the best fat burners for you:


The ingredients are one of the most important things you should look at first. The substances used to make the pill will help you figure out how effective and beneficial it may be for losing weight. 

There are a few questions to keep in mind when researching ingredients – how are the ingredients beneficial for losing weight? Is the dosage the right amount for intake?

Main Functions

  • Appetite Suppressants – These are supplements that may suppress the appetite, which means you can feel satiated for a longer period. It is good for those that eat more and snack when they shouldn’t. It allows you to consume enough food for your body to use.
  • Fat Burners – These are supplements that are considered thermogenic fat burners, which increase body temperature, which in turn may accelerate the fat-burning process of the body. The more heat your body produces, the more fat is burned.
  • Fat Inhibitors – Some fat-burning supplements available in the market focus on stopping the body from absorbing fat. It ensures that any surplus of fat left in the body is removed through the bowel to prevent it from being stored in the tissues.
  • Non-stimulants – These supplements function as fat burners but do not contain any stimulants, like caffeine. They encourage weight loss by focusing on eliminating fat and suppressing hunger without affecting your energy.

Value for Money

Another factor to consider when choosing a weight loss supplement is the price of the product. All fat burners available in the market vary in price because of the ingredients, the quantity in each container, and how the pills are manufactured. 

There are supplements available from each end of the spectrum – from low to expensive prices. Some brands even offer bulk purchasing offers, which encourages buyer loyalty. 

Type of Product

Fat-burning supplements are available in a variety of forms, from pills and capsules to tea, coffee, and powders. The type you purchase will depend on what fits your lifestyle. 

If you are a busy, on-the-go type person, then you are probably better off with capsules; or if you like the preparation, then powders for shake drinks could be an ideal option. It is up to you how much effort you want to put into it.

What Are the Functions of a Fat Burner?

Fat burners may be effective agents of weight loss because they are formulated to help promote the following functions in the body:

  • May help to control appetite, hunger, and cravings
  • May help initiate thermogenesis in the body, which increases temperature and may instigate the fat burning process.
  • Fat burners also have ingredients that may rejuvenate energy levels, perfect for maintaining an active lifestyle

The factors listed above are ways to help your body lose weight effectively. You must also remember that to lose weight effectively, you must use these fat burners in addition to healthy eating and exercise. 

Note that fat burners cannot magically break down fat and help you to lose weight without any effort from you – so you must also put in some of the hard work. It is part of the training to be more mindful of eating habits and movement.

Many fat burners use various approaches to burn fat and banish weight; some only use two of the factors listed above, and some might be potent enough to include all the factors. 

It depends on what you want from the supplement. Do you want to stop cravings? Do you want more energy? There are many functions to consider, so take care in outlining these before you make a choice.

Should You Use Fat Burners?

This is a good question to ask yourself when you start shopping for your supplement. One of the things to keep in mind is that supplements are an accompaniment to the regime already set in place. 

If you find yourself losing only a small amount of weight after some time of diet and exercise, or feel like you have plateaued in your efforts, then perhaps it may be a good idea to consider fat burners.

Fat burners may give you more energy and help you feel less lethargic from dieting, which can be good for keeping you motivated when exercising. 

Men and women can both use fat burners. You must check the brand if it is specific to a gender. Some might encourage muscle gain along with fat loss, which is often favored more by men. It is particularly important to check because some products may contain ingredients that could increase male hormones or female hormones.

Some fat burner supplements may help with bad sleeping patterns because they often use ingredients that can help initiate sleep hormones in the body. Lack of sleep can be one of the side-effects of weight loss, and it is important to identify it and find a supplement that aids this issue.

Overall, fat burners can be ideal for your weight loss goals. If you need something to give you an extra push in addition to your diet and exercise routine, then fat burners may be useful in helping you achieve your goals.

How to Make the Most of Fat Burner Supplements?

One of the key factors that helps fat burners be successful is the amount of effort you put into it. A healthy eating plan and exercise regime must be in place to aid an effective and fast weight loss. 

Here are some steps to consider to make sure that the supplements you have chosen work effectively:

Speak to Your Medical Professional

It is important to talk to your medical professional, especially if you have underlying health issues, to make sure that what you are using will be effective but, most importantly, safe. 

Some ingredients used in fat burner pills may have an adverse effect on the user or the medication you may be taking. The medical professional can also guide you with the best health plan to maximize the benefits of the supplements. 

Medical professionals can also give you sound advice on workout routines or healthy eating habits. If you need someone to check your efforts and motivate you, then consulting a doctor can be beneficial.

Formulate A Plan for Your Weight Loss

Being successful in losing weight doesn’t just happen overnight because you decided on it. It takes effort and hard work. One thing that can motivate and regulate your weight loss is cultivating a routine or plan to aid your goal.

Having a healthy routine, such as creating a healthy meal plan or accommodating an exercise regime in your day-to-day life, can boost your mindset for losing weight. This kind of determination is the best way to make your fat burner supplement go a long way.

Your weight loss should factor in habits that you may want to curb, like snacking or overeating; there are supplements available out there for you to buy for this purpose. Perhaps you want more energy, since dieting can sometimes leave you lethargic, so certain supplements will include ingredients that may boost your energy levels.

Healthy Eating

All diets or weight loss regimes require a healthy eating plan that is balanced and rich in nutrients. Having a good healthy meal plan can keep your body nourished, especially if you have added a rigorous exercise routine to your weight loss. 

A healthy meal plan can often help the absorption of fat burner ingredients into your system, which can enhance the benefits of the supplement.

It Is also an excellent way to change your mindset on food. It can help you explore types of food that you may have never tasted before. It can also reduce your intake of complex carbs and sugars because you can introduce more natural food items into your system. 

It will mean that your body will have more of the vital nutrients it needs to improve and lose weight. Adding water to the diet is also essential. It is vital to keep hydrated during the day, and it is advised to have at least eight glasses of water per day.


One of the most important attitudes to have when trying to lose weight is consistency. The supplements have required daily doses to work alongside your diet and exercise, so keeping at it every day can help the effects. Having a solid routine can instill consistency in your routines.

The results of supplements and weight loss routines can sometimes take weeks or even months. The main thing is not to lose motivation but to keep in mind that you aren’t just losing weight but are improving your lifestyle, as this mentality will help you avoid putting on weight again.

What Are the Side Effects of Fat Burners?

There are a variety of fat burner supplements available out there, and you have to keep in mind that some of them may not be safe. One of the key things to check is that the supplement you have chosen is 100% natural, for example, PhenQ, Instant Knockout, and Leanbean.

Fat burners with natural ingredients are generally considered safer because they don’t have artificial products that could negatively impact the body. The ingredients listed in the fat burners above all have beneficial ingredients that may improve the system of your body. 

Make sure that when you are looking at a fat burner supplement, you are checking for unknown additives that you might have to be cautious of. Artificial products can cause side effects, allergies, and even anxiety. Some of them might even have adverse effects on the medication you may be taking – so be incredibly careful and consult a doctor before purchasing.

If you are nursing or pregnant, then you need to avoid using all kinds of diet supplements. Also, if you have a medical condition, see a medical professional before making your purchase.
