Do Fat Burners work?

When it comes to research, the answer is a big “Maybe”.

But when it comes to what people think, the answer is yes. Fat burners do work and the main reason for this is the testimonials and customer reviews themselves.

There are a lot of artificially made fat burner supplements out there and they may be effective but they’ll likely cause problems due to the side effects of their artificial manufacturing.

ProVen on the other hand is a brand that you can trust to have little to no side effects thanks to having all of its ingredients be natural. Not only are they 100% natural but they also bring numerous health benefits to the table as well. 

These ingredients being turmeric, green tea extract, garlic, Panax ginseng, lycopene, selenium, vitamin c, vitamin e, arabinogalactan, essiac tea complex, and a variety of bioflavonoids that can help the body.

ProVen is also decently priced which is good for people who are on a budget. Sadly it doesn’t have the best customer reviews out there which is why it may not be getting the attention it needs like other thermogenic fat burners out there.

Overall, if you’re looking for a natural thermogenic fat burner with amazing ingredients like green tea extract, then you might want to check out ProVen for its reliable source and GMP certification.

Active PK

Active PK

See Full Review Of Active PK


Caffeine, green tea extract, and black pepper extract are very common ingredients that you’ll likely find inside weight loss pills and weight loss supplements. Caffeine and green tea extract not only help with losing weight but also provide energy as well. Sadly caffeine may have some side effects that some people may not want to experience.

Weight loss supplements like Active PK is a good choice for your weight loss goals if you want to follow a diet and exercise plan without having to rely on caffeine. The product only contains all-natural ingredients like quercetin dihydrate, berberine HCL, and gynostemma pentaphyllum leaf extract.

Berberine for example is known[3] to help deal with metabolic syndrome which goes to show that Active PK isn’t just about weight loss but it also helps the person achieve a better and healthier body.

Overall, Active PK deserves all the recommendations that it’s getting. The product may not be able to boost energy and body temperature as well as other products but its natural ingredients and the health benefits they bring, more than make up for this weakness.


Thermofight X

If you’re following a ketogenic diet and exercise regimen then you might want to try out ThermofightX. Not only does it boost ketosis but it’s also good for the blood.

  • Accelerates ketosis
  • Improves thermogenesis
  • Boosts energy

  • Contain some allergens
  • May damage the liver

See Full Review Of ThermofightX


Weight loss ingredients and an appetite suppressant are very common amongst the best thermogenic fat burners out there but it is rare to see a thermogenic fat burner support the ketogenic diet. 

And that’s where Thermofight X comes in, considered as one of the best thermogenic fat burner by a lot of people, this product contains ingredients that not only help with weight loss and boost metabolism but also help with ketosis as well.

It contains ingredients like cayenne fruit, green tea leaf extract, chromium, ginger, acai fruit extract, and raspberry ketones. All of these ingredients affect your metabolism in a certain way whether it be affecting your appetite or speeding up fat burning.

A good example of this would be green tea extract which shows that it can help with fat oxidation[4]. Sadly the results of the study are somewhat inconsistent and even though it works it’s hard to tell how effective it really is.

Overall, Thermofight X is one of the few fat-burning supplements out there that not only help you lose weight but also support people’s lifestyle choices as well. A ketogenic diet is hard to do and you’ll find cravings and the temptation of weight gain coming to you on a daily basis. Thermofight X will help you get through those temptations without compromising anything.



If you’re looking to lose weight and still keep your muscle mass then you might want to check out Razalean. It helps suppress the appetite making it a reliable fat burner supplement.

  • Keto-friendly
  • Stops food craving
  • Improved weight loss

  • May cause nausea
  • Website looks sketchy

See Full Review Of Razalean


Razalean is an amazing fat burner supplement that gets overshadowed by other products here that promote thermogenesis. One of the biggest issues when losing weight is controlling our food craving and Razalean is the best at doing this. 

The product contains ingredients like Garcinia Cambogia which is known to help suppress the appetite[5]. Other noteworthy ingredients are capsicum (black pepper extract), caffeine, kelp, turmeric root extract, l-arginine, apple cider vinegar, Rhodiola, raspberry ketones, green coffee bean extract, and caffeine. 

Couple these ingredients with proper diet and exercise, and you’ll be able to lose weight in no time! The presence of caffeine will also boost your energy levels as well making it far easier to keep with any exercise routine. 

Sadly a lot of customer reviews say that they experience health problems like nausea when taking Razalean, so it’s best you take this into account and follow the proper dosage stated on the product’s label.

Burn XT

If you don’t have a lot of money to spare for fat-burning supplements then you might want to check out Burn XT. It’s a cheap product but it’s still effective despite the price.

  • Helps preserve muscle mass
  • Powerful fat burner
  • Good pricing

  • Some negative side effects
  • High caffeine content

See Full Review Of Burn XT


Burn XT is a very popular product on this list and one of the major reasons why it’s being received so well is its price. A lot of fat burners often tend to be expensive and that puts a lot of people off from buying them.

Aside from the price, Burn XT can help you retain your muscles even with weight loss which makes it a good choice for people who want to cut some extra fat but still keep up their forms. Majority of Burn XY products also boost energy which does help out a lot when it comes to workout.

Here is a list of Burn XT ingredients: Acetyl-L-Carnitine, Green Tea Extract, Capsimax, Bioperine, and Caffeine Anhydrous. It’s a small list of ingredients but it’s still very effective even amongst the top fat-burning pills on this list.

Sadly because of its high caffeine content, a lot of people tend to experience symptoms like headaches and dizziness. This is one of the few negatives of Burn XT as it just doesn’t just burn your fats but it might burn away your consciousness due to excessive caffeine. 

Overall, Burn XT is a product that we highly recommend especially because it’s very cheap. Just make sure to take it sparingly since you might get a headache if you take too much.



LeanMode is a Halal-certified weight loss supplement which makes it a good choice for Muslims who want to burn fat while still keeping up with their religious beliefs.

  • Halal Certified
  • Powerful appetite suppressor
  • Improved weight loss

  • No money back guarantee
  • High daily consumption

See Full Review Of LeanMode


The act of weight loss should be open to all people and it doesn’t matter what religious beliefs and cultural practices you follow. Sadly there aren’t a lot of Halal-certified weight loss supplements out there which is concerning for people who follow the strict rules of the Quran.

Luckily for them, LeanMode is a Halal-certified product that will help them lose weight without having to defy the rules of their fate. Aside from this, LeanMode is an effective fat burner and it helps boost metabolism. And of course, it contains ingredients that help suppress the appetite. 

Ingredients of LeanMode include: green coffee beans, green tea extract, acetyl-l-carnitine, Garcinia Cambogia contains hydroxycitric acid, and CLA (conjugated linoleic acid). All of these ingredients are GMP certified and they will produce the best results for weight loss. 

Overall, LeanMode is an amazing product that is a good addition to its list. Being Halal certified will certainly help attract more people of different cultures that may not be open to taking the non-Halal certified ingredients of other fat burner supplements.



QuadraLean is one of the best choices for bodybuilding on this list. Unlike other products on this list, it contains ingredients that will improve your focus resulting in more productive workouts.

  • Improved focus
  • Good reputation
  • Natural Caffeine

  • Low thermogenic concentration

See Full Review Of QuandraLean


Last but not the least is QuadraLean. A high-quality fat burner that also helps you perform well in your exercises. The brand claims that taking QuadraLean will give you more focus and willpower allowing you to do this tedious and straining exercise. A lot of customer reviews praise them for this effect so we don’t doubt the brand’s claim. 

QuadraLean is made up of Conjugated linoleic acid,acetyl-l-carnitine, citrus Aurantium, natural caffeine, choline bitartrate, alpha gpc 50%, yohimbine extract, cayenne pepper extract, and paradoxine®.

Sadly its thermogenic ingredients aren’t as high in concentration compared to the others on this list which makes it a little bit inferior to other fat burners. However, it’s still effective at improving metabolism and unlike other fat burners its caffeine content isn’t too high which helps reduce side effects like nausea and headaches.

Overall, QuadraLean is a highly recommended fat burner for bodybuilding thanks to the added focus it gives its users. It may not be the best at thermogenesis but it’s still an amazing product nonetheless.

InstantKnockout features a product ideal for pro athletes and it is known to provide a lot of energy for men who want to perform their best during exercise. 

Best Fat Burner for Women

And to make things even more effective, a lot of fat burners contain other ingredients that are known to help boost the body’s metabolism which definitely speeds up the process. 

Suppress Appetite

Last but not least we have appetite suppression. Most fat burners also include ingredients that help prevent food cravings which can be detrimental for people following a specific diet plan. One such ingredient that you’ll find is  Garcinia cambogia extract which does have scientific backing for its effectiveness. A study[7] about a product containing Garcinia cambogia extract shows that it does help with weight loss but only in the short term. 

Potential side effects

If you’ve read all of the product’s descriptions and labels, you might notice that a lot of them share a lot of common ingredients. One of the most common ingredients is caffeine and some fat burners even contain too much caffeine which does lead to some bad side effects. People who overdose on these fat burners often complain about:

  • Headaches
  • Dizziness
  • Anxiety
  • Drowsiness

How To Take Thermogenic Fat Burner & Dosage

It varies depending on the product. Most fat burners have a recommended dosage of 2-4 pills a day, with others requiring even more. So there’s no general answer that we can give you and instead we recommend that you take a look at the product label.

Of course, we also advise that you consult your doctor first before following the dosage as you might have conditions or health problems that will cause complications by following some dosages.

Best Time to Take Fat Burner

The best time to take fat burners would be in the morning to help boost up your metabolism and a few minutes before training. It is highly recommended that you supplement your fat burners with adequate exercises to make them more effective.
