10 Best Diet Pills for Women in 2020


Fit girl

Are you looking for something to help you get a more athletic and toned body?

Do you want to get skinny quickly, while staying strong and healthy?

If so, you’re not alone!

Thankfully, there is a burgeoning industry for weight loss supplements.

These products – also known as fat burners – are designed to help with weight loss.

They’re designed to improve the results you’d see anyway from a healthy lifestyle built around calorie control – that is, a good diet and regular exercise.

In the booming weight-loss market it can be difficult to tell which diet pills work, and which are trying to cash in on your desire to lose weight.

Some products base their formula in science. They look to scientific studies and publications from health safety authorities to make sure their ingredients are effective, have proven effects and, most importantly, are safe to consume.

Others don’t do this. Instead, they rely on fad ingredients and trends to make sales, with very little thought about what their product will actually do.

Here’s the thing:

The vast majority of weight loss pills go one of two ways. Either they don’t work at all, or they include ingredients that aren’t safe for women.

On the other hand, the best supplements work as advertised and are safe. They are designed to complement a lifestyle built around calorie control and, when taken as directed, they’ll deliver results.

To find the ‘Ferrari of diet pills’ you need to do research. You need to understand what ingredients they contain, why they’re used, whether they work, and how all this combines to help with your weight loss goals.

If that’s what you’re looking for, then read on…

The Best Diet Pills for Women

We’ve put a list together of the most popular diet pills for women, we’ve done the research and looked at the best ingredients in each one, profiled the company’s behind the products and reviewed what the customers have been saying.


#1 Leanbean


Queen of the fat-burning castle, our top-rated product is the female fat burner called Leanbean.

Why are so many people using this diet pill?

In short, it helps you burn fat more quickly whilst getting your body to resist the urge to snack.

What’s the Score?

The manufacturer behind Leanbean is a company called Ultimate Life, they’ve put everything into creating a weight loss supplement that works for women.

In particular, Leanbean includes clinically proven doses of the appetite suppressant Glucomannan. Their daily dose of 3g has been legally approved by the EFSA to contribute to weight loss.

This same dose is also now considered to be a good source of dietary fiber by the FDA.

Leanbean’s makers have also included ingredients like Choline to improve fat metabolism and chloride to support better digestion as well as reduced bloat.

The result is a formula that:

  • Cuts cravings
  • Charges up energy
  • Turns on your metabolism

Leanbean before and after


  • 3g daily dose of Glucomannan
  • Choline to improve fat metabolism
  • Strong testimonials on website
  • Moneyback guarantee

  • Premium price tag

Leanbean is our highest rated diet pill for women. We chose it due to the impressive weight loss claims its makers are legally able to make in the EU.

You also can’t knock a product that exclusively serves the needs of women. After all, there are already thousands of supplements made for men!

Leanbean’s uses the best ingredients and its superior doses will give you the tools you need to achieve your weight loss goals.

It also comes with a money-back guarantee on the three-month purchases meaning you can return after 90 days if you are not happy. For more information, check out our complete Leanbean review.

#2 Hourglass

 Hourglass Diet Pill

Up next, we’ve got a newer diet pill called Hourglass that is another really nice product. This one is known for both its appetite suppressant and fat burning qualities.

What’s the Score?

Like Leanbean and Powher, Hourglass is also aimed more at women than men, although the formulation is arguably a little more unisex than our number 1 pick.

This one is a little cheaper than our first selection so that may help some of you who are looking to save money. We like the combination of a few top metabolism-boosting ingredients paired with natural diet aids like Capsimax.

Ingredient Highlights

  • Glucomannan – Well-known fiber suppresses appetite so you eat less.
  • Green Tea – To help metabolize fat.
  • Capsimax Powder – This ingredient suppresses appetite and also increases metabolism

Final Judgement

Another well put together diet pill that’s rightly popular due to the inclusion of some top ingredients. This one is another great selection that will definitely help with weight loss and is less expensive.

#3 Powher Female Fat Burner

Powher Fat Burner

Powher – the female fat burner – is a newcomer to the marketplace that looks set to make waves thanks to a fantastic formula, intelligent ingredients, and optimal doses for female weight loss.

Sounds too good to be true? Let’s take a closer look.

What’s the score?

This is the latest fat burner from UK supplement specialist Ultimate Life. With Powher they’ve built on their previous successes to create a fat burner that is at the top of its game.

The Powher formula focuses on appetite suppression, backed up with ingredients that will boost your metabolism and maximize your cardio output.

Ingredient highlights

  • 3000 mg of Glucomannan – a natural fiber that is excellent at appetite suppression.
  • Natural caffeine – for a safe and energizing stimulant hit.
  • Selenium – for healthy thyroid function, resulting in healthy metabolism.
  • Choline – to turbocharge your body’s lipid metabolism, letting you burn fat fast.

  • Other ingredients to complement and enhance those above.

Final judgment

Powher’s female fat burner is a strong contender in our list of best diet pills for women. The formula is the result of thorough research and represents the claims made by leading scientific literature about the best ingredients – and dosages – for weight loss.

For women looking to burn fat more quickly than they would through diet and exercise alone, Powher is a great choice. You can enjoy the peace of mind of knowing that your supplement is tailored for your physiological needs rather than something generic or male-focused, as is so common in the marketplace.

#4  Instant Knockout

Best Fat burner for women

Forth on the list is Instant Knockout. This one isn’t a female product in itself but it’s got a nice blend of ingredients that suit both men and women.

What’s the Score?

Like our top choice, this one is used by professional athletes looking to hone their physical output in the gym. The company behind this one is called Roar Ambition, they don’t just make diet pills but also manufacture a range of other sports supplements designed to naturally enhance performance.

Ingredient Highlights

  • Caffeine Anhydrous – Better fat burning after workouts.
  • Glucomannan – To help you feel fuller and make dieting easier.

#5 Quadralean

Quadra Lean


Next in our line up is Quadralean Thermogenic. The makers say that this product will help you lose fat whilst providing you with natural, clean energy.

What’s the score?

The Quadralean weight management pill is made by RSP Nutrition, you can find the product on Amazon as well as other well-known bodybuilding websites. It’s got a few of our favorite fat burning ingredients but is not quite the complete package.

Ingredient Highlights

  • Caffeine – Includes 200mg derived from Green Tea.
  • Cayenne Pepper – Includes this top ingredient but not as much as we’d have liked.

Final Judgement

This fat burner is not a bad choice for those looking for a cheap diet pill. There are quite a few of the top ingredients that don’t feature in this one though so it wouldn’t be our first choice.

This one also uses Bitter Orange and Yohimbe, both of which have been reported to cause minor side effects in a few cases.

#6 Vitamin Bounty Keto BHB

top diet pills

A supplement designed to complement a ketogenic diet, which the makers claim will help you to use fat instead of carbs for energy. “Ketogenic ROCKET FUEL!” is what the makers claim, and the popularity of this supplement suggests they may be right.

What’s the score?

Keto BHB is made by Vitamin Bounty and is available to buy on Amazon and elsewhere. It’s got pretty solid reviews across the board, and it looks geared up to help anybody looking to lose weight through ketosis.

Ingredient Highlights

  • BHB Salts– These salts – short for beta-hydroxybutyrate – encourage your body to burn fat instead of carbs through ketosis.

Final Judgement

If you’re interested in a ketogenic fat burner, Keto BHB could be a good choice. It’s got stonking reviews on Amazon, and ranks highly in their best-selling weight loss supplements list, so you can rest assured that you’re getting something people like.

The ingredient list is fairly slim, but it contains the BHB salts that ketogenic supplements are built around. You can also stack this supplement with others in their range to amplify its effect.

#7 Burn-XT

Burn-XT Fat Burner

Here’s the best-selling weight loss supplement on Amazon. It’s got over 15,000 reviews, the majority of them positive. The formula is fine-tuned to deliver weight loss results, through increased energy, increased fat burn, suppressed appetite, and boosted metabolism.

What’s the score?

The score is good. This supplement didn’t get to the top of Amazon’s best-seller list for no reason. Each capsule contains ingredients noted for their impact on weight loss and backed by research. There are a bunch of other benefits, too: Manufactured in the USA, GMP certified, and more..

Ingredient Highlights

  • Acetyl L-Carnitine – A renowned fat burner that transports fat to your cells to be burned.
  • Green tea extract – Provides energy and boosts your metabolism.
  • Caffeine – To power up your workout by keeping you alert and energized.

Final Judgement

This isn’t our favorite, but it’s a solid weight loss supplement. It comes at weight loss from several complementary angles, meaning a better chance of seeing results if taken alongside a healthy diet and regular exercise.



#8 Nobi Nutrition Night Time Fat Burner

diet pill

A supplement designed to burn fat while you sleep, which we imagine will appeal strongly to many readers. This product combines weight loss ingredients with those that will help you get a better night’s sleep.

What’s the score?

It’s a bit different from the other fat burners in our list, but we like Nobi’s contribution. By suppressing appetite and reducing night-time snack cravings, this supplement targets people at one of the trickiest times of the day to stay strong.

Ingredient Highlights

  • Phaseolamin – Extracted from kidney beans, of all places, this protein curbs cravings.
  • L-tryptophan – Involved in the production of serotonin in your brain, stimulating a better sleep.
  • L-theanine – An amino acid linked with the reduction of stress and anxiety.

Final Judgement

Something a little bit different that is proving to be popular on Amazon and beyond. If you want a supplement geared towards burning fat at night rather than through a more hardcore workout, this could be a good place to start looking.

#9 Vintage Burn

Vintage Burn Review

This supplement is a testament to the idea that great branding doesn’t detract from product quality. The art style and colors here are striking in a way not many fat burners are.

What’s the score?

Vintage Burn helps you to burn fat and preserve muscle. That second effect isn’t something many supplements claim, and Vintage Burn say they’re “the world’s first”. Whether you believe the buzz or not, the ingredient list is solid for weight loss.

Ingredient Highlights

  • Bacopa leaf extract – This extract is linked to better focus, useful for working out.
  • Raspberry ketones -Involved in metabolism and the efficient burning of fats in your cells.

Big, bold, and red. Vintage Burn’s fat burner is a popular weight loss supplement for men and women wanting something a little bit different. When a brand invests so much effort in standing out from the crowd, and people like the result, it’s usually worth a look.

#10 MAV Nutrition Night Time Fat Burner

mav Night Time Fat Burner

Here’s another night time fat burner, this time from the guys at MAV Nutrition. It claims to aid relaxation, support fat burn, and help you to get a better sleep. Sounds good to us.

What’s the score?

Build around a ‘Rest and Relax’ blend, this supplement is designed to help you burn fat while you sleep. Something a bit more gentle and relaxing than the macho, intense fat burners available on the market. Although a blend isn’t ideal (because it’s hard to know the exact ingredient quantities), this supplement seems to be effective.

Ingredient Highlights

  • Valerian root extract – A natural extract linked to relaxation and better sleep.
  • Lemon balm extract – Another calming extract to help you feel soothed.

Final Judgement

If you’re looking for a nighttime fat burner, there are now two solid options in this list. MAV’s contribution to this niche of supplements is well-received and is built around a suite of ingredients renowned for their weight loss and relaxation effects.

How Do the Best Diet Pills for Women Work?

Trim waist line

Ending the frustration of stubborn fat is hard.

Most likely your lifestyle changes are not working fast enough, and you need to push your results into higher gear.

That said, you might be thinking:

‘I don’t want to overdose on caffeine and harm my body just to lose weight’.

This is where the best diet pills for women come to the rescue, they include the best ingredients to shift fat safely.

These top ingredients help to:


#1 Reduce Your Appetite

Ever wondered why when you’re out for dinner it’s always the girls at the table that are craving dessert?

It’s not that men are some supreme beings when it comes to willpower it’s just that they got the luck of the draw when it comes to genetics. Studies of the female brain show that women feel cravings much more intensely.

How can a diet pill help lower your appetite?

The best weight loss pills are there to make dieting easier. That’s the point. They suppress your appetite by including fiber, this gives you the sensation of feeling fuller so you can avoid going off rails with your latest health-kick.


#2 A Quicker Metabolism

One of the big downsides with caffeine is that it can actually make you feel sick and leave you with less energy than when you started.

The good news is:

The best diet pills for women factor this in. The makers worked out that they can get the same if not better results by including natural spices and not synthetic stimulants.

Weight loss pills that include these potent fat burners raise your metabolic rate so you can burn more calories and lose weight.

That’s not all:


 #3 Boost Energy Levels

If your diet is making you feel sluggish in the gym then the chances are your progress could hit a wall. Taking one of the best diet pills comes with the added benefit of boosting your energy levels.

Choose the right one and you shouldn’t feel any side effects from sticking to a low-calorie diet.

In fact, you’ll be able to make your workouts more intense and still eat fewer carbs.


The Ingredients Inside the Best Diet Pills for Women?

The best diet pills for women contain the most up-to-date ingredients for boosting weight loss.

We’ve compiled a list of some of the most proven fat burning ingredients here. It’s worth noting that despite tons of ingredients making their way into fat burner formulas, only a handful have actually been recognized as effective for weight loss. Where this is the case, we’ve made a note.

Glucomannan – AKA konjac root – for weight loss


This soluble fiber is a wonder-ingredient that features in tons of weight loss supplements thanks to its appetite suppression properties. It expands inside your stomach, making you feel more quickly than you would otherwise.

This weight loss effect has been backed up by scientific studies, and health safety authorities note that 3g per day is most effective for weight loss.


Raspberry Ketones


Raspberry Ketones actually put the ‘diet’ in ‘diet pill’ by lowering your appetite and forcing you to eat fewer calories. 2

Studies have also revealed that this ‘fragrant’ compound slows the accumulation of fat thanks to the active ingredient Capsaicin.


Garcinia Cambogia

Garcinia Cambogia

The ‘go-to’ appetite suppressant in Hollywood, Garcinia Cambogia stops weight gain by blocking the enzyme linked to the production of fatty acids.

It also suppresses your appetite by releasing serotonin, this works by telling your body to feel full and eat less.

A trial of 60 people saw significant weight loss results amongst the control group by the end of an 8-week study. 3




This spice can send your weight loss goals to ‘light speed’ by directly reducing fat tissue.

Turmeric is a thermogenic that has caffeine like results on your metabolism without causing side effects.

It also prevents ‘weight regain and stops ‘yo-yo dieting’, so once you successfully burn fat there’s less chance of it rearing its ugly head again. 4


Cayenne pepper

Cayenne pepper

Cayenne Pepper is the potent chili that lights the fire within the best diet pills. This ‘capsinoid’ raises body temperature and increases energy used by the body – this results in fewer calories being stored. 5

What’s more, a double-blind study showed reduced body weight amongst volunteers within a 2-4 week period.


Green Tea

green tea

Green Tea is a top fat burner that will help you load up on antioxidants, get rid of love-handles and cut cellulite down to size.

The success comes down to the active fat burning ingredient ‘Catechins’, these ‘polyphenols’ have been shown to increase energy, boost metabolism and reduce total body fat – with or without the need for caffeine. 6




This nutrient helps your body maintain normal fat metabolism –  the process by which fats are stored, transported, and used in your body.

With a boosted metabolism, you’re better able to break down fat for energy. When fat is used for energy, it doesn’t stick around inside your body. 7

It’s also associated with lower cholesterol levels, important for your overall health.


Vitamin B

Vitamin b

Vitamin B actually refers to 8 separate vitamins – B1, 2, 3, 5, 6, 7, 9, and 12 (we don’t know either).

Most supplements contain B6 and B12, both of which are linked to a suite of positive effects. We’re talking boosting energy-yielding metabolism, contributing to nervous system function, and reducing tiredness and fatigue. 8

In short, it’ll help to power up your workout and keep you energized.




Chromium is a mineral involved in macronutrient metabolism. Ensuring you have enough means that your body will be better equipped to transport and store all macronutrients – not just fat. 9

It helps to regulate blood glucose levels as well. Elevated blood glucose is linked with all sorts of problems, so this regulation is a nice add-on effect to its weight loss credentials.


Do Diet Pills Work?

Zoe Daly abs

So do diet pills actually do anything?

Well, obesity is becoming a big problem ….

So it’s inevitable that better and better products will keep popping up!

But remember the best weight loss pills can’t just flush out fat in the blink of an eye.

That’s just not realistic.

So don’t choose a diet pill if you don’t have the motivation workout and put some effort in yourself.

Why use one then?

Well, using the best diet pills is a bit like making sure your car has the very best gas in the tank. The point is to power up your body’s natural fat-burning so you lose pounds quicker.

The best diet pills can:

  • Renew weight loss – break the stalemate with your body
  • Help improve your figure – remove soft areas of fat uncovering your abs
  • Make healthy eating easier – stop sugar cravings head-on

Fat burners can make great alternatives to prescription weight loss medication like Phentermine. If you’re looking for the best phentermine alternative, one of the supplements in the list above may be a good start.

Best Diet Pills Before and After Pregnancy

To get pregnant quicker you’ll need to burn fat and get in shape, the best diet pills can help make this happen. Equally, taking a fat burner to get your body back after pregnancy can be really effective.


If you’re actually pregnant or breastfeeding it’s not usually recommended to take weight loss pills.

Many diet pills use stimulants so you’ll want to make sure you do your research properly or check with your doctor before purchasing a diet pill that’s safe to use.


Fat burner FAQs

Can diet pills cause anxiety?

If you take a diet pill that has a high dose of caffeine in it there is a chance you could get anxiety as a side effect of the caffeine.


What are the best diet pills without caffeine?

2 of the first 3 diet pills on our list are caffeine-free which are Leanbean and Hourglass so they would be your best choices.


Diet pills vs exercise, which works better?

Both will work but you also need to have a solid diet. If you try and just take diet pills or just exercise for weight loss but have a poor diet you will get little to no results.


Where to buy fat burners?

Fat burners are available on Amazon, as well as GNC, Walmart, and numerous other online and offline sources. Many manufacturers sell supplements direct at their website (like Leanbean, for example). You can buy this type of supplement OTC (over the counter) because they’re not licensed medicines.


What is the best diet pills at Walmart?

Right now best diet pill at Walmart would be Alli Orlistat Diet Weight Loss Supplement Capsules. They don’t work as well as any of the products on our list but they may give you some benefits.


When should you take diet pills?

That would depend on what diet pill you are taking. If it has caffeine in it you should take it in the morning and earlier in the day so it doesn’t keep you up at night. If there is no caffeine in it you can take it anytime. It is best to read the label and take it when the manufacturer says to take it, of course.


What are the best diet pills on the market today?

Right now Leanbean is the best diet pill on the market followed by Powher and Hourglass. There are newer and better products coming out all the time though so that may change, stay tuned.


So what is the best diet pill to burn belly fat and make cellulite disappear?

Well, hopefully, this list goes some way to providing the answers to those important questions.

We’ve chosen Leanbean as the best diet pill for women. It uses the safest weight loss ingredients that actually work.

Don’t forget:

The best diet pills are the ones that support your training and help you convert your fitness efforts into amazing weight loss transformations.

While you’ll need to exercise and eat clean, using a weight loss pill to boost your metabolism and curb cravings will help you break the plateau to get your beach body quicker.
