1. Editor's Choice: LeanBean

​LeanBean was designed for women to help provide them with a safe, effective method for burning through fat and preventing the formation of new fat deposits.

LeanBean is one of the few vegetarian fat burners for women, as well as one of the best fat burning supplements period.​

It leans heavily on cayenne pepper to boost metabolism and garcinia cambogia to suppress appetite.

There's a modest dose of caffeine to give your workouts a boost but nothing that's going to disrupt your sleep cycle.

Best Price GreenBTN

If a flatter stomach, firmer butt, and greater stamina are notions that interest you, LeanBean can help you achieve them safely and quickly.


  • ​One of the few vegan-friendly fat burners for women.
  • ​Does an above average job suppressing appetite.
  • ​The caffeine dose is moderate.
  • ​Your money back if you are not completely satisfied.


  • ​May cause upset stomach.

2. Instant Knockout

​Instant Knockout by GNC has earned major props for being the best fat burning supplements out there.

Rather than getting all its metabolic enhancing energy from caffeine alone, Instant Knockout looks to nature in the form of green tea extract, green coffee extract, cayenne pepper, zinc and more.

All of these are known to boost metabolism safely and effectively as well as helping build and maintain lean, powerful muscles.

Sure, there's a bit of caffeine.

But the dose here is mild compared to some, and you'll never wind up with the jitters as a result.

This is a highly pure formulation that will help reduce food cravings, power up your workouts and help you stave off the creation of new, essentially useless fat stores.


  • ​A well-balanced formula of proven fat burners.
  • ​Helps build strong, resilient muscle tissue.
  • ​Enhances energy levels and focus.
  • ​Satisfaction guaranteed or your money back.


  • ​Not suitable for vegans.

​3. ​PhenQ

​PhenQ contains an amalgam of thermogenic ingredients, appetite suppressants, and energy boosters.

The net result is a product that lives up to the considerable hype surrounding it and does so safely and without cleaning out your bank account.

The makers of PhenQ have gone to great effort to create one of the best weight loss pills for women that gets the job done without creating jitters, upset stomachs or insomnia.

About the only downside of PhenQ is that the appetite suppressant is not everything it’s hyped up to be.

But beyond that, it's all good.

Best Price GreenBTN

​Capsimax powder to promote thermogenesis, calcium carbonate to reduce the likelihood of storing excessive amounts of fat and caffeine to increase metabolism and get you up and ready to roll at the gym.


  • ​Helps burn excess fat through thermogenesis.
  • ​Enhances energy levels and focus.
  • ​Moderate appetite suppressing capabilities.


  • ​Shouldn’t be taken too close to bedtime.

4. LEAN-XT Non Stimulant Fat Burner

​Lean-XT attacks the problem of stubborn fat deposits from all angles.

It includes metabolic boosters to prevent new fat stores from forming, appetite suppressants to keep you away from the refrigerator and coleus forskohlii for enhanced cardiovascular health.

If we have a bone to pick with Lean-XT, it's that the makers advertise it as stimulant-free, when in fact it counts green tea extract among its ingredients.

And while the caffeine load from green tea isn't the same as a double espresso, there is caffeine nonetheless.

So take that for what it's worth.

​Beyond that minor quibble, however, Lean-XT is one of the top fat burners for women and does a commendable job burning off those excess fat stores while the caffeine load there is isn’t enough to keep you awake at night.


  • ​Includes coleus forskohlii for cardio health.
  • ​Enhances metabolic function.
  • ​Helps to suppress appetite.
  • ​Money back satisfaction guarantee.


  • ​Despite claims contains some caffeine.

5. Transparent Labs

​The Physique Series Fat Burner from Transparent Labs is a tour-de-force of clinically proven ingredients.

It provides a multitude of benefits including enhanced metabolic rate, increased energy to power through your workouts and improved mental acuity resulting from more oxygen-carrying blood pumping through your veins.

It's one of the more unheralded items on our list, but you'd do well to give it a shot.

If there is a downside to the Physique Series women's fat burner, it's that they're a little heavy-handed with the caffeine.

If that's not a problem for you, then you're going to love Transparent Labs.

​If it is, you might want to try a smaller dose rather than opting for one of the​ best diet pills for women. Just because the product as a whole is so effective.


  • ​Caffeine and L-theanine for energy.
  • ​Green tea to facilitate muscle recovery.
  • ​Forslean and cayenne pepper to burn through stubborn fat deposits.


  • ​Heavy on the caffeine.

6. RSP QuadraLean

​QuadraLean is one of new generation of the best ​diet pills for women that are trying to steer away from excessive dependence on stimulants. The good news is they succeed!

That’s mostly because they focus instead on enhancing thermogenesis which, as we saw above, is the process of elevating your metabolic rate. This has two primary effects.

First, it helps you burn off the food you eat before it turns into new fat stores and second, it attacks the fat stores you do have and puts them in play as a source of energy.

The end result is no more jitters, no more insomnia and no more upset stomachs from ingesting too much caffeine.

​The icing on the cake is that it’s made in a certified GMP facility so you can be sure of the quality.


  • ​Enhances your natural metabolic processes.
  • ​Suppresses appetite to help you keep weight off.
  • ​Can be stacked with a range of other health supplements.
  • ​No stimulants to keep you awake at night.


  • ​Appetite control claims may be exaggerated.

​7. ​Evlution Nutrition Leanmode

​Leanmode is loaded with scientifically proven metabolism enhancers, fat burners, and energy boosters that will enable you to get more from your exercises.

It will also help you build the kind of lean, strong body you have in mind.

Leanmode contains L-carnitine, which is one of the building blocks of protein, which of course is the foundation of muscles.

It also includes green coffee bean extract to boost energy and mediate blood glucose levels and CLA, which helps metabolize fat to energy.

​Together, these and other ingredients allow you to burn fat more effectively during workouts while improving blood flow, oxygen distribution to enhance your focus and recover from strenuous workouts faster than ever.


  • ​Increases metabolic rate.
  • ​Provides energy to power fat-burning workouts.
  • ​Helps muscles recover faster and grow stronger.
  • ​Improves oxygen flow to both muscles and brain.


  • ​Don’t expect a caffeine boost.

​What to Look for in a Good Fat Burner

Any supplement claiming to be the best fat burner for women should ramp up your metabolism, suppress your appetite, help you burn fat and prevent your body from turning carbs into a useless spare tire.

As such, the best fat burners for women should include some or all of these 5 ingredients:

  • ​Caffeine - Still the best natural stimulant ever discovered. If used wisely caffeine will enable you to perform more vigorous and productive workouts. Even if you don’t work out, caffeine will still get you up and out of your chair which is the first step in burning calories and reducing fat. [1]
  • Zinc- Zinc is known to play an important role in muscle recovery and maintenance. It also helps increase your metabolism, energy levels and stamina. Though not in an obvious way like caffeine.
  • Green Coffee Bean Extract - People often feel like napping after they eat because their blood sugar levels are spiking. Green coffee bean extract can help reduce the absorption of blood glucose. This helps you maintain your energy levels and burn more fat.

  • ​L-Theanine - L-theanine is an essential amino acid that fulfills a variety of roles including fat burning and helping to restore muscles quickly in the wake of a strenuous workout. Numerous studies have shown that the combination of theanine and caffeine burns fat.
  • Cayenne Pepper - Cayenne pepper is one of those ingredients in fat burners for women that works not by doing something but by preventing you from doing something. In this case, cayenne pepper will help suppress your appetite. And the less you eat, the less fat there will be to burn. [2]
  • ​Thermogenic ingredients - Thermogenesis is the production of heat within the body and is driven by your metabolic rate. Any ingredients that help increase your metabolic rate have thermogenic qualities and will help you burn fat even while at rest. Caffeine and green tea are two such ingredients.

​​​​What to Avoid in Fat Burners for Women?

what to avoid in fat burners
  • ​Ephedra - In an unprecedented move, the US FDA banned the sale of products containing ephedra in 2003. Some 150+ deaths related to ephedra-containing products had been reported before the FDA was forced to act. Some companies, however, try to get around the ban by selling over the Internet. The best weight loss supplements for women won’t use it. [3]
  • ​DMAE - Dimethylaminoethanol or DMAE is included in some fat burners for women under the guise that it burns fat and increases cognitive function. It doesn’t. Not only that, but it has a bunch of nasty side effects including headaches, manic episodes, constipation, bloating and insomnia.
  • DMAA - Allegedly the equivalent to a super-espresso DMAA (or dimethylamylamine) is dangerous. There have been reports of cardiac arrest, cerebral hemorrhage, high blood pressure and even death in people who used it. The best thermogenic for women won’t touch it. [4]
  • Bitter Orange Extract aka Synephrine - While Synephrine is usually safe when consumed in small doses anything more than 50 grams per day could lead to fainting, chest pains, and elevated heart rate. Synephrine might also cause you to test positive for amphetamines on a company drug test. [5]

​Bitter orange contains an active ingredient called synephrine that is similar to ephedra. In 2004, the FDA banned ephedra for serious side effects on the heart. Many weight loss and bodybuilding products contain bitter orange and caffeine, which can cause high blood pressure and increased heart rate in healthy adults. There is concern that using bitter orange might cause heart problems. 


​Are There Any Potential Side Effects?

While fat burners for women are typically safe when used as directed, they have been known to generate some side effects including:

  • ​Allergic reactions - Some fat burners for women contain ingredients that may trigger allergic reactions.
  • ​Mood changes - Fat burners that include stimulants can sometimes generate shifts in a woman’s mood. You may also feel hyperactive or suffer hot flashes or insomnia.
  • ​Stomach problems - Some women with more sensitive digestive systems may find that some fat burners give them an upset stomach. A few might experience diarrhea or constipation.
moody woman
  • Flatulence - While rare there are still some women whose systems will react negatively to some of the ingredients in fat burners for women. With flatulence being the result.
  • Undeclared ingredients - Some fat burners from unscrupulous manufacturers take advantage of the lack of FDA oversight of the industry to sneak in unwanted ingredients. The most notable is excessive amounts of caffeine. Always buy from a reputable company.
  • ​Heart palpitations - Because of the sometimes substantial caffeine load found in some fat burners for women those with a family history of heart problems may want to avoid them. Or at least find one that is free of stimulants.

​[However,] overuse of metabolism stimulants has its own adverse effects. Prolonged use causes your metabolism to slow down in self preservation. Thus, these fat burners do not retain their effectiveness for a long time.
