You will also find information about what you should look out for when choosing a fat burner including false claims, side effects, and a lot more.

So, if you want to know which are the most effective fat burners for women, check out this in-depth guide.

What You Should Consider

If you are interested in using fat burning pills, you may be wondering whether they work or not. This is a very good question to ask and the answer is, yes, they do work. This guide prioritizes products and supplements that have proven benefits and are suitable for women.

Finding the best fat burning products for women usually comes down to looking at their ingredients, claims, amount of stimulant as well as online reviews.

Here are the fat burning products we consider to be best suited for women in 2021.

1. Leanbean - Best Overall Fat Burner

Leanbean has been reportedly touted as one of the best fat burners. 


  • Has a proven and effective fat-burning formula
  • Suppresses appetite and helps control cravings
  • Has 3g of glucomannan which has been approved for weight loss
  • Is fully vegan
  • Is available on discount at different stores
  • Has been proven to be effective, is grounded in science, and is very popular

Leanbean is a fat burner that does not contain any stimulants. It suppresses your appetite

How Does it Work?

Leanbean relies on its 3g of glucomannan which has been approved by the EU as an effective weight loss solution. Glucomannan is a natural fiber that reduces your calorie intake which makes your body convert fewer calories to fat. This puts you well on your way to losing weight as I outlined in my Leanbean review last month.

Leanbean also contains chromium which has been shown to help users maintain a healthy weight while helping maintain normal blood sugar levels.

Additionally, it contains choline which has been shown to increase the rate of fat metabolism.

For the best results, Leanbean should be used as part of a healthy lifestyle. It will help you have fewer cravings, eat smaller meals and have better control over what you eat.

2. Powher - the Best Fat Burner That Contains Caffeine

Powher is a popular fat burner that contains caffeine. Some of its benefits include:

  • It increases your energy levels and metabolism to help you see better results from your workouts
  • It helps you eat a lot less food due to the 3g of glucomannan it contains
  • It helps you maintain a caloric deficit that is very important if you want to lose weight
  • It is specially formulated for women and can be bought at different stores where you can get bulk discounts and a money-back guarantee

In addition to glucomannan, Powher also contains a healthy dose of caffeine. Caffeine raises your core body temperature and increases your metabolism so you can burn more fat. Powher is best used in an active lifestyle where users can take advantage of higher metabolism levels.

The unique blend in this fat burner includes minerals, fibers, and natural stimulants that can help you work harder for longer. The primary aim of using Powher is to increase the number of calories you use so you can lose weight faster.

3. Littledrops - Appetite Suppression Using CBD

A lot of people have not considered using CBD to reduce their appetites because it is generally assumed that CDB gives you cravings. However, CDB can be used for fat suppression because it is a fun and tasty way to reduce your appetite and food intake at the same time and it can promote brown fat cells, thereby helping increase fat loss. CDB is also different from capsules and diet pills and its use helps support farmers who grow hemp. 

Because not everyone wants to take their pills with water before or after a meal, trying a CBD gummy like Littledrops is a great alternative.  Each gummy has 20 mg of CBD. This amount is high enough to get you buzzed but not high enough to get you too high.

Littledrop gummies are a great alternative and you should try them to see if they are a great option for you.

4. ShredFIERCE - A Potent Metabolism Booster

The key to weight loss is a healthy metabolism. ShredFIERCE is a potent metabolism booster and that is why it has made it onto this list.


  • Boosts your metabolism so it can help you lose weight
  • It raises the number of calories you burn which can help you get a lot more out of your workouts
  • Raises energy levels and reduces your appetite so you have more energy with fewer cravings
  • Does not contain any chemicals as it contains only natural ingredients

One thing you might notice if you look at Shred FIERCE’s website is that it looks like this product is meant for men. It may be advertised as such, but this product is not only for use by men. Men and women burn fat in the same way, the only difference is that women feel cravings a lot more than men. Additionally, women work out differently and all these factors combined lead to women needing a fat-burning product that is specifically created for them. 

Women who want to have harder workouts, hack their metabolism, and burn through stubborn fat reserves should try a product like ShredFIERCE.

5. Alli - A Fat Burner Free of Stimulants

You might know that phentermine requires that you have a prescription to buy it. However, if you are looking for an over-the-counter alternative, Alli is the best option for you.

Here’s why:

  • Alli is a drug meant to help with obesity and it is not a supplement
  • Its active ingredient, Orlistat, is only available with a prescription
  • You do not need a prescription to purchase Alli

Alli delivers the same results you would see if you used a prescription drug without having to get one from your doctor.

How Does it Work?

Alli contains 60 mg of Orlistat. This is one of the strongest fat burners and the amount contained in this product is half the amount you would get if you bought it using a prescription. Orlistat helps your body reduce the amount of fat it absorbs through your digestive system.

The reason why you require a prescription for Orlistat is that it has some side effects that can be particularly nasty and is meant to be used by people with a BMI of over 28. You should not exceed the dose that you are required to take, so read the instructions carefully before you start taking Alli.

What You Need to Know Before Purchasing Fat Burners for Women - Are They a Scam?

There are hundreds of fat burners that you can purchase on popular platforms such as GNC, Amazon, or Walmart. The unfortunate thing is that many of the supplements you will find at these outlets make bold claims that are not backed by science. Because there are too many products to count, it can be difficult and confusing to find the right products and ones that do work. 

Choosing the best fat burner often depends on understanding a few things. Here are some of the things you should always check:

  • The claims being made - Is the product making outrageous claims? If yes, you should stay away from that product. The best fat burners make realistic claims, claims that are in line with what is allows by bodies such as EFGA.
  • The ingredients included - All fat-burning products should have a list of all the ingredients it contains. Once you see what ingredients are included, you can check them out online to see if they offer any fat-burning benefits. 
  • Is the recommended dose linked to the claims being offered? - Having the right ingredients is one thing, but having enough of these ingredients is a different matter. The amount included in a single dose should be enough to cause the desired effect.
  • If the price makes sense - The price of fat-burning products varies a lot. Some products are cheap and do not work while some are priced so high that they are not worth it. You should always aim for the middle as it is possible to get products at this price that include an effective dose.
  • Customer reviews - You should always check to see what others are saying about a particular product before you purchase it. Many websites and outlets let customers leave testimonials and reviews which you can use to find out how others feel about a product.

Having a checklist like the one above is a great way to protect yourself against misinformation, to ensure you do not buy a product only due to the hype that surrounds it, and to give yourself a chance to purchase products that would work well for you.

How Do Natural Fat Burners Work?

Although men and women metabolize and burn fat in similar ways, there are minute differences that make certain ingredients work better for women than they do for men. Because of this, fat burning products meant for women will usually focus on a few key things that apply mostly to women.

Natural fat burners work in different ways and we will look at some of these mechanisms now. 

Suppressing the Appetite 

Research has shown that women experience stronger cravings than men. In studies, women have been shown to experience up to 15.6% more food craving instances than men. This is a primary reason why a sizable number of women struggle to lose weight. Because of this, reducing cravings is an important component of weight loss products meant for women.

Ingredients that help suppress the appetite work in two ways; they either take up physical space in your stomach so you always feel full and need to eat less, or they interfere with the neurotransmitters that signal to the brain that you are hungry.  

If you gain weight because you eat a larger quantity than you need to, your body is storing more calories than it needs to use for energy. Natural ingredients can help you eat less and thereby lose weight. The key ingredients that should be included in your weight loss products include:

● Glucomannan: This is a natural fiber that expands and takes up more space when it comes into contact with water. Once it takes up physical space in your stomach, you will feel full sooner and therefore eat less. When used right, glucomannan is an effective weight loss ingredient.

● 5-HTP: 5-HTP is used by the brain to produce serotonin. Higher levels of serotonin in the body make you feel less hungry. 

● CBD: CDB is extracted from marijuana and it has become a popular appetite suppressant. Research has linked CBD to reduced caloric intake and appetite suppression even though how it does this is not fully understood.

Boosting Your Metabolism

Metabolism is the process through which your body turns the food you eat into energy. Supplements that boost your metabolism help you utilize more calories for energy production instead of storing them as fat.

Some supplements do this by raising your heart rate while others help you maintain a healthy metabolism through the inclusion of minerals and vitamins. Others include stimulants to help raise your metabolic rate.

It is important to remember that men and women have different levels of tolerance to caffeine and their bodies respond differently to the effects of caffeine and other stimulants. One study showed that women who have higher levels of estrogen feel the effects of caffeine and other stimulants while men can handle higher levels of caffeine and other stimulants.

Because of this, fat-burning products that are meant for women will usually not have ingredients such as guarana and synephrine. When they include caffeine, it is usually in smaller doses than that found in weight loss supplements meant for men. 

Here is a look at two of the most potent metabolic boosters:

● Vitamin B6: Vitamin B6 is understood to play an important role in many of our metabolic processes. This is why Vitamin B6 features in many fat burning products.

● L-carnitine: This is another popular metabolism booster that you will see in many fat burning products. L-carnitine is an amino acid that helps transfer fats into cells where they are used for the production of energy.


Thermogenesis is simply the process of heat production in the body, and fat burning supplements claim to do exactly this. They are meant to make the body produce more heat, which puts a larger demand on the body to produce additional energy and this ends up forcing the body to burn more fats to produce this energy. 

Many of the products that cause thermogenesis contain capsaicin which is the chemical that makes chilis taste spicy. They also contain turmeric and caffeine.

Some of the studios that back up the effects of thermogenic ingredients state that the thermogenic properties of turmeric have been known for centuries. Green tea extract, another thermogenic ingredient has been shown to increase body temperature. Green tea extract is also so effective because it can help you burn fat even when at rest, thereby helping you lose weight in most situations.

What to Avoid When Choosing a Fat Burner

Some fat burner producers and diet pill manufacturers are more interested in making a profit than ensuring the products they sell you are safe. In this section, we will look at how you can avoid harmful ingredients and find a fat burning product that works for you.

Fat Burners to Avoid

The reason why manufacturers have so much flexibility when manufacturing these products is that they are not regulated by the FDA. This is why products that contain harmful ingredients have continued to flood the market. Many of the ones that have negative effects on their users have been removed from the market. However, it is still a good idea to keep an eye on what you are buying to ensure you are not harming yourself under the guise of losing weight.


Ephedra can speed up your heart rate while raising your blood pressure at the same time. This can have drastic consequences for the users. The use of ephedra in certain products has been linked to at least two negative side effects - heart attacks, and non-fatal strokes. 


When the use of ephedra was banned, the popularity of and interest in synephrine skyrocketed. These products are very similar and produce the same effects although synephrine does so at a lower scale.

Synephrine is sold as p-synephrine, m-synephrine, and o-synephrine. The use of m-synephrine is so high because it can cross the blood-brain barrier and stimulate the brain. It is not known to cause any fatalities or adverse reactions when used alone but it can do so when used together with caffeine.

2,4 Dinitrophenol (DNP)

This compound has been around since the 1930s and has been shown to have a powerful effect on metabolism. 

However, it was banned later that decade because it was shown to be fatal when used in some ways. Sadly, this compound can still be found in some supplements. It is very dangerous, illegal and you should avoid any products that contain this compound. Also, you should report any products that list it as an ingredient.

Side Effects

Because many of the ingredients used in mainstream diet pills and fat burners are natural, they do not usually cause adverse side effects. However, there is still a chance that you will experience some side effects.

Some of the more common side effects include jitters, bloating, diarrhea, gastrointestinal discomfort, and anxiety.

Jitters and anxiety are usually linked to products that contain caffeine, so ensure the dosage included is right for you before taking supplements that contain caffeine. 

Many of the other side effects listed above can occur due to taking more than the recommended dosage or the product having a larger quantity of ingredients than is listed on the bottle or packaging.

If you encounter any side effects, your best course of action is to stop taking the supplement immediately and consult a doctor.

What are Prescription and Over-the-Counter Fat Burners?

Prescription fat burners are products that have regulatory approval. Prescription fat burners are prescribed when there is an urgent weight loss need, such as the need to lose weight quickly or when a condition or illness is responsible for your weight gain or inability to lose weight. 

Because prescription fat burners have undergone rigorous tests and checks, they are usually more potent than their over-the-counter counterparts. Because they are very aggressive in their mode of action, you will require medical supervision when taking them. This is so that any side effects can be noted and treated right away.

You will not be able to get prescription fat burners unless your doctor deems them to be medically necessary. A doctor or other qualified medical professional must prescribe them for you. 

Prescription fat burners are very powerful and can cause the following side effects:

  • Diarrhea
  • Oily stools
  • Temporary incontinence
  • Gastrointestinal distress

Fat Burner FAQs

While this guide is detailed and comprehensive, you will likely have some questions when looking for a fat burner. So, here are some of the frequently asked questions and their answers to help you out.

When Should I Take the Fat Burner?

Fat burners are best taken 30-40 minutes before your meals. This gives them time to enter the digestive system, break down and get to work.

Because every product is different, it is also recommended to check the bottle to see the specific instructions given.

If the product contains caffeine, take extra care not to take it close to your bedtime. Caffeine is a stimulant and can make it harder to fall asleep.

Are Fat Burners Safe?

Night-time fat burners are products meant to help your body burn fat when you are asleep. Although normal metabolism still happens while you are asleep, these products are meant to boost that process.

Because they are meant to work while you sleep, these products will usually have mild or different ingredients from other supplements. For example, you will not find caffeine or ingredients that make you energetic. Instead, you will find plant extracts that calm the mind and help you sleep better, plus thermogenic ingredients that raise your body temperature.

Night-time Fat Burners: What are They?

If they are taken as directed or according to the instructions on the bottle, fat burners are generally safe for most people.

However, if you take a higher dosage than is recommended, you will likely experience adverse effects. It is never a good idea to take more than one supplement at a time unless you have been told it is okay to do so, or to take more than the recommended dosage to multiply the effect of the supplements.

Can I Use Fat Burners While I am Pregnant?

It is generally not advisable to use any supplements or diet pills while you are pregnant. However, if you were already using one when you got pregnant, do talk to your doctor so they can advise you whether to continue or not. 

Can Fat Burners Work if I Do Not Exercise?

A lot of people use fat burners as their only way to lose weight. Weight loss requires that you utilize more calories than you consume and this is why exercise is such an important part of your weight loss journey. 

Although many of the best supplements are meant to increase your metabolism and help you use more calories, they are not meant to be used as a replacement for exercise.

Any supplement that claims to be a substitute for exercise is a scam and you should stay away from it.


This comprehensive guide has given you an in-depth view of five of the best fat burners for women in 2021. You should now have a better understanding of the pros and cons of different supplements and their ingredients and how different ingredients would work for you. If you are looking for a natural fat burner, then a product like Powher or Leanbean would be best for you. If you want to lose weight fast, Orlistat may be your best option. The bottom line is that it is up to you to choose the supplement that would work best for you and whether the benefits you get outweigh the potential downsides.
