best vegan fat burners

You’re making all the right choices when it comes to dieting, meal prepping and meticulously calculating your macros on a plant-based diet.

In addition to maintaining a strict vegan bodybuilder's diet you're also hitting the gym on a daily basis, pushing your absolute max.

In spite of all the effort put into the weight loss regimen, you are not shedding fat at the rate you want to. 

This is where a high-quality vegan thermogenic fat burner can come in handy, to give the last push needed to enter the fat burning zone. 

However finding a good vegan fat burner can be hard work and you might feel a little overwhelmed by all the choice out there.

Well, let me do the hard work and scour the market for the best vegan thermogenic fat burners. Read on and I’ll fill you in on this subject.

First of all: let's establish what a fat burner isn't

Before we dive into the mechanism by which fat burners work and the nitty-gritty of what specific ingredients do, there is something important that needs to be made clear first.

If you've ever watched Rocky you know that (spoiler alert!) beating Drago wasn't very easy. He had to run up and down a set of stairs god knows how many times and he had to use animal carcasses as punching bags (?).

Okay so the last part perhaps wasn't absolutely necessary and also a bit strange. Come on rocky use punching bags like normal people.

However, the point is that putting in hard work paid off and was what made him a champion ultimately.

See what I'm getting at with this talk of Rocky? Fat loss is made possible by hard work.

A vegan fat burning supplement is not a substitute for a good diet or solid training routine. If you haven't already established a proper diet and training regimen beforehand, you probably wont see any results from using these kind of supplements. 

With that being said used properly, and in the right context where you've already maxed out all other fat-burning factors, a vegan thermogenic fat burners can and will boost your efficiency of fat loss.

How does fat burners work?

A fatburning supplement doesn't work through magic, placebo or other inexplicable mechanisms.

Through multiple different pathways it helps to enhance weight and fat loss. 



While weight loss can seem like a mystery, in reality it is an extremely simple concept.

You put calories in your mouth.

If this amount of calories is less than your body uses, you will tap into your fat storages to provide sufficient energy. Voila, fat loss.

That's it.

The main mechanism by which fat burning supplements allow weight loss to occur is by their thermogenic effect and ability to boost metabolism. 

'Hold on a second what is a 'thermogenic' effect and how does it relate to metabolism?'

Good question.

Thermogenesis is simply the process of burning of calories that produces heat, which happens in all warm blooded organisms. Inducing and increasing the rate of thermogenesis will raise one’s metabolic rate or calories used by the body. 

As mentioned thermogenic fat burners has the capacity to induce further thermogenesis.

This directly facilitates fat loss to occur as it burn more calories, increasing overall energy expenditure and resting metabolic rate.

Increased energy and well-being

The mental game of fat loss is not to be downplayed. 

I mean we all should theoretically be able to lose weight, it is simply a matter of eating less.

But it isn't quite that easy, as evident by the epidemic of obesity. Here is another aspect where fat burner supplements supports weight loss.

One potent feature of thermogenic fat burners is that they help support increased focus, alertness, and energy.

So not only does fat burners directly affect fat loss by stoking our metabolic fire, they also indirectly affect fat loss by enhancing our mood.

This is essential to your success in losing weight due to several factors.

If you're in a good mood with plenty of energy and focus you're much more likely to stick to your diet and training regimen. That means adhering with your set calories and macros and really giving all you've got at the gym.

Curb appetite

monkey eating

How interested are you on going on a food binge when you have the flu, and not only that, but you're also violently sick?

What a strange question, I sense you thinking right now. 

Of course you're not interested eating when you feel like absolute crap. In fact it is such a struggle eating that you need to make a concentrated effort nibbling at small food bites to get any calories whatsoever.

What fat burners achieve is a similiar effect, albeit not to the same extreme degree as the provided example.

A suppressed appetite will translate into less food being eating. When you usually go for a quick snack you simply don't feel any hunger pang or urge to eat anymore. 

(No this was not an advertisement for getting violently sick as an optimal form of weight loss)

Ingredients of thermogenic supplements

So what's in there that can generate all of these effects in the body? Fairy dust, crack, sugar, MCT oil?

You'll find that many thermogenic supplements are very similiar in terms of composition. This is because there are a couple reliably proven ingredients that will help with the goal of weight and fat loss. 

Green tea extract


I reckon I would make a faily decent maker of clickbait titles on Facebook. 

However it is in fact true that green tea extract does aid in promoting fat loss. It has been shown in studies to help increase fat oxidation and metabolism, both short and long term.

So how does this work exactly?

Certain compounds called polyphenols are naturally present in green tea. In the scientific community these are called either flavanols or catechins.

There are a couple of different catechins in green tea, the most prominent one being epigallocatechin-3-gallate or EGCG.

In one randomized clinical trial, 690 mg of catechins ingested daily for 12 weeks significantly reduced the subjects' total fat area, waist circumference, skinfold thickness and subcutaneous fat area!

The benefits of green tea doesn't stop there.

As you might know green tea is also a source of caffeine. However what you might not know is that caffeine also has a thermogenic effect.

These two factors together, the duo of potent catechins and caffeine, really makes green tea extract a potent promoter of fat loss.


cups of coffee

As mentioned caffeine is another compound that induces thermogenesis and increases metabolic rate in the body. 

It has been shown that caffeine increases energy expenditure dose dependently along with the thermogenic response.

When you actually consider how caffeine affects you this shouldn't be a major surprise. Atleast for me two cups of strong black coffee will definitely make me more prone to fidget, walk around and feel like I want to go to a metal concert and jump around. 

 Capsaicinoids and Capsinoids

chili pepper


Alright, I will stop with these.

Capsaicinoids and capsinoids are the compounds that give chili and cayenne peppers their fiery hotness.

So why do supplement companies put traditional mexican food in their fat burners? 

Surprisingly these have been found to increase total energy expenditure as well as reduce appetite and energy intake. The mechanism behind this is not yet fully understood either.

However we can take advantage of this effect by putting them into thermogenic fat burners. 


an orange

Synphrine is another popular fat loss supplement. 

And it is quite potent. One study found that 50 mg of synephrine lead to a 65 calorie increase in resting metabolic rate compared to the control group. 

Synephrine works by increasing the metabolic rate via increasing fat oxidation and basal metabolic rate. In supplements it usually is found as bitter orange extract, as it naturally occurs in bitter oranges.

Before you go buy oranges in hopes of a chiseled physique I'll also you know that regular oranges don't contain synephrine.

Side effects of thermogenic supplements

More does not necessarily imply better here. 

If you've had a coffee drinking competition at work (this was not my brightest decision, for the love of god please don't do this) you will know that too much caffeine is not pleasant.

And for the record I did win that competition. Suck it David. 

Past a certain threshold you can experience adverse effects such as jitteriness, nausea and irritableness.

If you're sensitive to caffeine consumption sleep might come a bit harder when its bedtime. 

Fat burners are not meant to be used long-term either, only for short durations where you want a boost to fat burning.

It is a good idea to take these supplements in periods. Being constantly wired on stimulants and fat burning compounds can be quite taxing on the body and you need to allow your system some rest from time to time. 

What are the best vegan thermogenic fat burners for weight loss?

As there are so many different supplements out there, and not knowing which one is vegan, trying to find the right one can be like looking for a needle in a fatburner stack. 

To spare you the trouble I’ve taken a good thorough look at the market and come up with four producs which I think will work best for most people.

Vintage Burn Thermogenic Fat Burner

Old School Labs Vintage Burn is a 100% vegan thermogenic fat burner featuring a total of 9 ingredients that fuses together to create a unique, very potent thermogenic formula.

It’s designed to help you increase your energy expenditure and burn fat while at the same time preserving muscle mass.

In addition to its fat burning qualities it also improves mental focus, mood, and pre workout energy. Perfect to keep your head focused at weight loss and get you fired before your workout session.

This fat burner is free from any and all artificial colours and flavors. 

What I find so awesome about this particular product is the complete transparency; every single ingredient is listed and also the quantity of said ingredients. This way you know exactly what you're paying for and putting in your body. 

This product has also been third party tested for purity and potency for an extra layer of scrutiny.

Per serving you'll find powerful fat-shedding ingredients such as 

  • Green Tea Leaf Extract - 330mg.
  • Green Coffee Bean Extract - 270mg.
  • Raspberry Ketones - 200mg.
  • Caffeine - 150mg
  • Garcinia Fruit Extract - 100 mg 
  • Forskohlii Root Extract - 60 mg

Another thing I adore about this product is the clean ingredient list. Except for the active components there is only vegetable stearate and the vegetable capsule.

Considering the standing ovations from users, many providing transformation pictures, and the proven fat-burning ingredients this is a pretty great product. The only downside is the price tag which might be a bit steep for some people.

  • Each serving contains large amounts of ingredients proven to promote fat loss

As mentioned this supplement not only focuses its attention at fat burning, but also at enhacning cognitive function, memory and focus. Ingredients such as Ashwagandha helps combats high stress leveles to improve your mood. 

What I like about this supplement is that it's completely caffeine-free. The caffeine here is replaced by TeaCrine which is a great substitute for mental energy, without the crash afterwards.

So for anyone that gets uncomfortably jittery from caffeine consumption this is a good alternative. Or you could stack this supplement with caffeine or a pre-workout for an ultimate fat-burning effect and energy boost.

Per serving you'll find highly beneficial ingredients such as

  • TeaCrine - 100 mg
  • Ashwagandha - 300 mg

Downside is that as it is a top end supplement it is also quite expensive. Taking this months after months (which you shouldn't really do with fat burners) might burn a hole through your wallet.

It might not be for those with sensitive stomachs as some users experienced a sensation of feeling sick when trying it.

What I like about this specific produt is one component of this fat burner, the Advantra Z Bitter Orange Extract which contains naturally occurring p-synephrine. The combo of the caffeine found in the green tea and guarana seed and the p-synephrine is sure to get the metabolic fires burning.
