All my clients ultimately have one thing in common: they have fat loss goals that they are somehow struggling with.

It’s the same for performance athletes who are trying to cut down to the lowest possible BMI, as it is for people in their 50s who have ended up neglecting health and fitness for too long and need to shed some pounds.

The problem is that our bodies like to hold onto fat reserves. It’s an evolutionary concept that fat reserves are critical to avoid starvation when food becomes scarce. But scarcity and long fasting periods are pretty much things of the past.

While diet and exercising are the two most important factors for fat burning, there are numerous supplements that can help you achieve your goals faster.

On this page, I will be showing you the results of my month-long in-depth research into stimulant-free fat burners, which are ideal for anyone who is over-sensitive to caffeine.

Our Top Stimulant-Free Fat Burners

1 - Burn Lab Pro (Editor's Choice)

burn lab pro

First on our list of stimulant-free fat burners is a product that the entire team here has agreed to place in the top spot, including a dietitian I regularly work with.

We all liked that there is no confusion over what’s in this stim-free fat burner, as the company has kept it simple and doesn’t hide behind some proprietary nonsense.

Many users online point out that it works well to support fat loss training, thanks to the cayenne and forskolin. But it does one extra thing that convinced us all.

Check out our full Burn Lab Pro review.

Pros
  • Cayenne pepper works as a thermogenic
  • Forskolin improves hormonal balance to trigger fat metabolism
  • Contains HMB from branched-chain amino acids to retain muscle mass
  • Plant-based vegan-friendly product
Cons
  • Bulk buy savings could be a bit better

By adding an ingredient called HMB, which is derived from BCAAs (branched-chain amino acids), you can reportedly diminish the risk of muscle wasting during a fasting period.

It’s not the cheapest product, but you get what you pay for. And here, you get an all-natural, plant-based, top quality, stimulant-free fat burner formula. Some better bulk discounts would be nice though.

2 - LeanBean

One problem that most women have with fat-burning supplements is they are often formulated to support the larger doses intended for men. So, if you’re sick of trying to figure out which supplement with smaller dose to take, then check out LeanBean.

This is one of the main stimulant-free fat burners people on Facebook urged me to research because they had been using it successfully for quite a few months.

It’s completely stimulant-free, so if you need to take something later in the day or you’re just sensitive to caffeine, then it’s a solid choice. It also contains green tea, if that is something you'd like in your diet.

Related Articles:

Pros
  • All-natural ingredients with no harmful chemicals
  • Many reports of effective use without any stimulants
  • Positive impact on mental and physical energy
  • Claims to work well as an appetite suppressant by adding Garcinia Cambogia
Cons
  • Only available on the official website
  • Recommended dosage is 6 capsules per day

What stood out for me, though, was the added Garcinia Cambogia. Many people turn to this fruit extract to burn fat, but from my own experience, it works much better for appetite suppression, together with the 3000 mg of glucomannan.

This stim-free fat burner is also approved for weight loss in the European Union. To get the best results, it's recommended to take 6 capsules per day: 2 during breakfast, lunch, and dinner, respectively.

3 - Transparent Labs Fat Burner

Transparent Labs non stimulant fat burner

The next one on this list of stimulant-free fat burners is from Transparent Labs, and I’ve been a fan of their products for quite a while now.

This was the first time I tried their stim-free fat burner, and I did find the results positive.

In the majority of comments I reviewed, people did find their cutting phases more effective than before taking these stim-free fat burner.

My dietitian pointed to the acetyl L-Carnitine, which is a vital part of getting fatty acids to muscle cells where they are used as raw energy.

Pros
  • Good acetyl L-Carnitine dose to speed up fat processing
  • A simple formula of 6 ingredients that are backed by science
  • Added vitamin B12
  • No artificial crap added as sweetener, flavor, or preservative
Cons
  • You need to take 4 capsules daily for optimum effect

It’s great that the company prides itself in publishing all the details about their products, as it just takes the guesswork out of it. As you assess your tolerance, you will need to take 2 pills twice daily to burn body fat.

4 - Lean XT

This stim-free fat burner that Tracy here in the office recommended as she had seen a lot of positive results with her female clients.

And having read through a few hundred reviews and forum comments, this stim-free fat burner does seem to work well, especially to keep hunger at bay.

If you’re doing a calorie-restricted diet and struggling with eating less, then this can make quite a difference.

It also has a decent amount of green tea extract, which can help to burn fat, but more importantly, it can help with detox and getting rid of free radicals.

Pros
  • Many positive comments about suppressing food cravings
  • L-Carnitine speeds up fat loss
  • Contains green tea extract for detox
  • Claims to reduce your body’s ability to store fat
Cons
  • Limited bulk discount availability

I also saw a lot of comments about it helping to maintain weight by reducing your ability to create new fat storage. The only downside with this stim-free fat burner is that discounts are not readily available when you buy in bulk.

5 - EVL Nutrition Lean Mode

EVL Nutrition thumb

From the reviews I’ve read, this stim-free fat burner seems like to help give you some mental focus and motivation even without the stimulants that are so common in other fat burners.

A lot of people also commented that it works well to avoid hunger cravings during fasting periods or low-calorie diets.

Combine all that with CLA (Conjugated Linoleic Acid), and you get more fat burning to increase your energy output. You can definitely take advantage of that during high-intensity training to work hard on some lean muscle mass.

Pros
  • No jitters but you still get a good mental boost
  • Some positive comments about hunger suppression
  • Helps provide more energy for workouts
  • Contains CLA which has been shown to boost metabolic rates
Cons
  • You need to take 3 capsules for full daily serving

It’s not our top pick, and if you’re not on a strict budget, then I would suggest you try the Burn Lab Pro Fat Burner above.

EVL Nutrition Lean Mode is still a good stim-free fat burner option that will work better than not taking any supplement at all.

What Does Stimulant-Free Fat Burner Mean?

Stimulant-free fat burner means a supplement that doesn’t rely on some of the common stimulants like caffeine (more on this in the next section).

But what’s the problem with caffeine? Isn’t it effective?

Yes, it absolutely is, and countless clinical trials have shown that it works as a potent thermogenic. But it also has a stimulating effect on the brain, which is why so many of us simply cannot function without a coffee first thing in the morning.

For me, it’s a must, but Tracy here at the office would end up acting like Tweak from Southpark, so a stim-free fat burner is something she needs to have a.

 

What Type Of Stimulants Should You Avoid?

If you know that you’re sensitive to the effects of a coffee or strong cup of tea, you should always look out for the following on the nutritional label.

1. Caffeine

Caffeine

This is by far the most common, and you’ll see it referenced as either natural or anhydrous.

Both have the same effects, but they are produced in slightly different ways.

Natural caffeine is extracted from coffee beans in a very similar way as a cup of coffee would.

However, anhydrous is extracted from seeds and leaves, which creates a very concentrated powder. (1)

Caffeine anhydrous is made from the seeds and leaves of coffee plants. The word “anhydrous” means “without water.” After harvesting, caffeine is extracted from the plant matter and dehydrated. This produces a highly concentrated caffeine powder.
- Debra Rose Wilson, Holistic Healthcare Practitioner

2. Taurine

white powder; Taurine

This is something you’ll find less often in supplements because it’s actually more common in energy drinks. (2)

But some manufacturers will market their formulas as stimulant-free fat burners, yet they still add in some taurine.

The real potency of this amino acid is still not clear, but I generally tell my clients to stay away from it.

What Effects Do Fat Burners Have?

I could say that fat burners aid your metabolism to shed some flabby stuff and end this section, or I could bore you with an essay on what happens in your body. But, I’ll do neither and just give you a quick summary of the effects fat burners have on weight loss.

1. Thermogenesis

This is a metabolic process where your core temperature is slightly raised. And in order to achieve this, you have to burn off some energy. Once the readily available blood glucose has been diminished, your body will start to go after fat reserves. (3)

The result is an effective way to get more out of your daily diet and exercise routine.

2. Appetite Suppression

It’s no secret that in order to lose weight, you have to eat less and healthy. That often means that you need to go on a net negative calorie diet, and that can often lead to hunger pains and cravings.

By filling you up or curbing certain hunger hormones, fat burners can make it far easier for you to stick with your diet through appetite suppression.

3. Reduced Ability To Store Fat

This is something that’s often overlooked, but being able to maintain your weight is just as important as losing it. Many options these days will include stuff that will inhibit your body’s ability to transform excess calories into fat.

The result is lower chances of constant weight fluctuations.

4. Increased Training Performance

Of course, all the energy that gets released has to find a home. If you time your intake well, then you can also achieve some extra energy for your training. And if this isn’t enough, then why not try a product that contains creatine as well?

When Should You Take Fat Burners?

The great thing about stimulant-free fat burners is that you don’t have to be as careful about their impact on your ability to sleep at night. I generally recommend weight loss options that are spread out over 2 to 3 doses a day, like LeanBean and PowHer.

This supports your metabolism better as it keeps it firing at a higher rate, from morning to evening. If you’ve never taken fat burners before, then aim to take them with your meals. Some of them can be a bit tough on your stomach.

What Natural Ingredients Work As Fat Burners?

What Natural Ingredients Work As Fat Burners

For a long time, the health and fitness industry just focused on telling people to load up on some whey protein and reduce carbs and calories. But science has advanced, and there are a few more things that you should look out for when it comes to fat burners for weight loss.

1. Conjugated Linoleic Acid

It’s difficult to pronounce, so let’s just call it CLA as it’s known in the nutrition industry. There has been some controversy over it, but increasing numbers of studies have revealed a link to weight loss. (4)

2. Forskolin

Sourced from the roots of an Asian plant, some studies have revealed a link to it being able to increase the release of stored fat. (5) How effective it actually is hasn’t been quantified, but as it’s such a natural ingredient, it has the advantage of no known negative impact.

3. L-Carnitine

This amino acid is believed to work by helping to transport fatty acids that have been broken down from fat storage. The more fatty acids that can be transported to muscle cells, the faster you can melt body fat away.

4. Green Tea Extract

If you don’t like drinking green tea like me, it doesn’t mean that you don’t have a way to take advantage of this modest fat burner and potent antioxidant. In a concentrated extract form, you can get a big boost to your overall health from green tea.

FAQs

What is the best stim-free appetite suppressant?

The best stim-free appetite suppressant is natural fiber as it swells up in your stomach and in many cases passes through undigested, so it doesn’t count towards your calories. Konjac fiber is one of the best options I have found to be the most filling.

Is apple cider vinegar a fat burner?

Yes, apple cider vinegar is a fat burner, and adding 1 to 2 tablespoons to your food per day can make a difference. I recommend you get an organic product, as they are generally more nutritiously valuable.

What is the best natural fat burner ingredient?

The best natural fat burner ingredient is caffeine, but if you need something that isn’t stimulating, then whey protein has been proven to work great for fat loss. Just make sure to lower your carb intake, and you could be helping your body shed some body fat.

Which Stimulant-Free Fat Burner Should You Pick?

So, after endless hours of reading online reviews, knowing the metabolic types, interviewing dietitians, and having some of the team members test the products, we managed to come to a conclusion as to which one deserves the top spot from these best stim-fat burners for weight loss.

We all kept going back to Burn Lab Pro. This stim-free fat burner strikes a great balance between melting away body fat and helping to build and retain some muscle mass and tissue as well.

If you haven’t tried it before, then I highly recommend placing an order today.

And remember to let us know how your experience was.

  1. Great blog, Isaac. I just want to ask: Are there any big difference between stimulants that with non-stimulants as it relates to assisting burning fat?

  2. Hello Isaac. I love this article! I’m searching one for my stepfather — he has diabetes and needs to begin setting off his calories. We went to a center and looked for a doctor. We asked him as to whether he can go have some of these. He agreed as long as it is low in calorie. this is great!!! Energized for him to attempt that stuff. He has a fitness coach who will assist him with the exercises and his dietitian from the emergency clinic will design his nutritional intake. I am certain he will be in his best shape in the blink of an eye while battling his illness. Love you dad! I am doing this for you!!!

  3. Wow. Thank you for writing this wonderful article. I am much obliged to you for continually setting aside effort to inform us about these things, which are extremely accommodating stuff!!! my friend shared one of your surveys previously and here I am, dependent on your substance. I generally read your substance and 100% of the time, I gain some new useful knowledge. I love your style, and my friend and I generally talk about your suggestions! I likewise like the activity tips and diet prompt, makes me increasingly cognizant about my heath. Keep helping out other people online!

  4. how I wish we can be at a time where all that we need to eat are directly in the terrace. I have lived with my great mother and her house has had bean stews, tomatoes, onions, garlics and a few leaves in her nursery – we can simply pick something on and off by chance whenever we need it! for nothing! great occasions. anyway, I live in an apartment suite now and I don’t have a nursery so the rancher’s market is my companion with regards to toppings and cooking stuff. Your tips are truly helpful for people like me. Keep writing Sir.

  5. Nearly everybody I know takes supplements these days. They have become some portion of our day to day diet, and the business is colossal without a doubt. Capitalism has overtaken these. Truly, these organizations win billions of dollars. I for one feel that everybody needs them particularly with all the unnatural nourishments we have now from the junkfoods to fastfood restaurants and instant foods from convenience stores! Cheap food here, inexpensive food there, inexpensive food all over the place. As much as we need to eat healthy, it may be very well hard to do most especially when everything is happening all at once and we need to keep moving as time is ticking. The best way to go about it is to improve our diet as much as we can so we get all the things we need in our bodies and ensure that we’re all solid and safe constantly! These tricks sure do help people like me who are in constant motion due to all the stresses of the world. Hope to read more from you Isaac. Keep us posted.

  6. I have an inquiry with regards to this point, I am on keto diet, and I am searching for something that I can use for my work out. I have been utilizing this brand from my nearby basic food supermarket and it’s alright, then again, actually it is high in sugars and conflicts with what I am attempting to accomplish with my eating routine. I discovered your blog and further research on your proposals. I have read all related works available online as I could ever search of. I am amazed that I didn’t have a clue about these sorts of items existed until just now!!! Imagine! So bless your heart! I have simply submitted a request form of purchase now. I am hoping and anticipating the delivery on Monday. So excited to receive it at long last after taking me forever to look for a product that best fits my needs.

  7. I love your blog, Isaac. been binge reading for the past week and I’m learning a lot with all the great deal of information from your blog. That is because of all of your sources of info! My friends and I are doing a challenge this week. Since we’re all in quarantine, we are doing a wellness challenge and whoever loses the most weight during this quarantine period wins. This will be a hard one since I previously increased 3 lbs the previous 3 days LOL however I’m resolved! Having read your blogs, I took an interest at these items and they got me extremely intrigued. Will these work? Will I win against my friends?? Hopefully! I have not attempted to take in any from before yet I am shock the ones on this list are truly reasonable for their purpose, though not certain what the normal cost is. Looking forward to this. Will be updating to whatever result there may be for me or my friends! Wish us luck.

  8. First of all, I am a huge follower of you Isaac. Ever since I found out about your blog, I got lmost addicted to it and updates myself ever so often whenever I can. To be honest, this is my go to blog for useful information of items I found on the internet. Well, most certainly because you talk about things honestly and are concerned about your readers. That truly is remarkable for me and with that, let me express my gratitude. Thank you, Isaac. Continue to giving out useful information to the community, we will keep on supporting you and your group. Secondly, I have been reading a lot of similar information as you. With that, since this is coming from you, I am actually looking forward to using this as my wife and I have been looking for the right supplement for us. And I’m considering getting this because of you. By the way, it’s good if you’re in keto right? Would love to try it if it is.

  9. Okay, so my friend and I were talking about this topic a few days ago because she discovered this new product that she says works for her. I certainly cannot believe what she is saying so when I checked the label, damn it’s just 98% s u g a r! Can you believe it? Practically she has been just consuming sugar? Not sure though if she realized that before trying the product. So I immediately told her that the effect she is feeling is more of a sugar rush rather than actual pump. Anyway, I informed her about your blog and with this list. I ran down to her what I recommend especially the ones you truly trust. Basically the top products I believe I have learned from reading your blogs. I also gave to her what I have used that had good results with it that you have suggested Sir Isaac. Plus, it’s pure! Unlike what she had been taking which is essentially sugar! Definitely a waste of money from her. I hope she likes it so she stops taking all the car bs from that BS product she was taking. I will influence her to read your blog so we can stan you together with your latest post. Thanks!

  10. I think the most ideal approach to taking these is to converse with an expert, regardless of whether that be your nutritionist, specialist, or mentor at the gym. It is hard to pick one thing that will work best for you, as we as a whole have various responses to these things. Your primary care physician will consistently encourage you to take things easy and slowly especially when taking these. And it is hard to believe, but it is true. You at any rate need to begin with low portion and gradually in the end increase the increment as you become more acquainted with how your body responds to it. Nearly everybody in my family practices a keto diet. And we have utilized a considerable lot of these types of products, so I would say the brand does not make a difference, what is important is your body and how you feel about it. Buckle down, eat healthy, and you will feel great paying little mind to what your “diet” is! Thank you Isaac for having your amazing input as always. You sure have been helping me as to how I decide to deal with any changes in my routine. Looking forward for the next blog.

  11. I always prefer the best non-stimulant diet pills since they have no caffeine. It’s different for everybody but this info is helpful as always.
