All clients I meet 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 where fat reserves were critical to avoid starvation when food becomes scarce. But scarcity and long fasting periods are pretty much a thing 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 fast.

On this page, I will be showing you my research results into stimulant free fat burners, which are ideal for anyone that is over-sensitive to caffeine.

Our Top Stimulant-Free Fat Burners

1 - Performance Lab Fat Burner (Editor's Choice)

Performance Lab non stimulant fat burnerthumb

First on our list of stimulant free fat burners is a product that the entire team here has agreed to place in the number 1 spot and this was also backed by a dietitian I regularly work with.

We all liked that there is no confusion over what’s in this weight loss supplement, 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 ingredients. But it does one extra thing that convinced us all.

Check out our full Performance Lab Fat Burner 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, 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 non stimulant fat burner formula. Some better bulk discounts would be nice though.

2 - LeanBean

One problem that most women will have is that fat burning supplements are often formulated to support the larger doses needed for men. So, if you’re a woman and sick of trying to figure out what smaller dose you need 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 a completely stimulant free fat burner, 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 a requirement 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

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 in appetite suppression.

It has 3000mg of Glucomannan and it’s approved for weight loss in the European Union. It’s also recommended to take 6 capsules per day: 2 during breakfast, lunch, and dinner, respectively.

Certainly worth a try for all women reading this.

3 - Transparent Labs Fat Burner

Transparent Labs non stimulant fat burner

The next one on this list of stimulant free fat burners comes 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 non stimulant fat burner, but I did find the results were positive.

In the majority of comments I reviewed, people did find that their cutting phases more effective than before taking these.

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.

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. Just be prepared that you will need to take 2 pills twice daily to burn body fat.

Check out our full Performance Labs Fat Burner review.

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

4 - Lean XT

This is a product 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 stimulant 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 will 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 product is that discounts are not readily available when you buy in bulk.

5 - EVL Nutrition Lean Mode

OK, here’s the final product I would recommend, and from the reviews I’ve read, it seems like it still helps to give you some mental focus and motivation even without the stimulants that are so common in other supplements.

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

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

You can read our full review of the product here.

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 Performance Lab Fat Burner above. But it’s still a good stimulant 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 it’s something she needs to avoid in all her supplements.

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 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.

2. Taurine

white powder; Taurine

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

But some producers will market their formulas as a non stimulant weight loss supplement, and then 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, you 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 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 less chance of constant weight fluctuations.

4. Increased Training Performance

Of course, all that 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 caffeine 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 these 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 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 amount of stored fat that is released. (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 impacts.

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 that can be transported to muscle cells, the faster you can melt away fat.

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 non stimulant appetite suppressant?

The best non stimulant 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 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?

The best natural fat burner 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 you lower your carb intake at the same time, and you could be helping your body shed some extra pounds.

Are fat burners dangerous?

No, most fat burners are not dangerous, but you need to stay away from those that contain chemicals and medication. If you stick with options that contain all-natural sources, then you shouldn’t see any negative effects.

Which Fat Burner Should You Pick?

So, after endless hours of reading online reviews, knowing what metabolic type, interviewing dietitians and having some of the team test the products, we did manage to come to a conclusion as to which one deserves the top spot from these best non stimulant fat burners for weight loss.

We all kept going back to Performance Lab. It strikes a great balance between melting away the flabby stuff 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.

About the author

  • Thanks to this instant knockout review, I’m now leaner and stronger! Gotta say that this fat burner is legit!

  • I have shed over 30 pounds using this product and with the right gym sessions and regime, I was able to gain so me muscles too. This one is legit. I highly recommend it. I experienced a little bit of a reaction during the first few days, I could not sleep! But eventually my body adjusted to it and I felt great. It gave me more energy and I felt the burn everytime I do my routine. My friend who’s into fitness even commended me because I work too hard and give it my all when I am in the gym! All because of this product. I love that it does it what it’s supposed to do and more

  • Hey Isaac. It has been a while since I last visited your post. By the way, thanks for your awesome breakdown of this wonderful product. I have been using it for a little while now since I saw it in your website. What I have noticed while using this product is that with the high caffeine dosage, I can’t drink a cup of coffee in the morning and take this at the same time without stomach issues. I received an advice from my friend a couple of days ago saying he can help me out with my stomach issues. I look forward to reading more from you. Thanks in advance!

  • Just wanted to say that thank you as always for your in-depth analysis of this amazing product. Since postage, I have been using this product for about 2 months now. Within that span of time, I went from 250 to 210 pounds! It was a great milestone for me because usually it takes me longer to lose so much. To give a background of what I have been doing, I rarely worked out or went to the gym. I just ate healthier, all the fruits and vegetables and less of those junk. I walked 4 miles every other day, and just was sensible about everything I did or ate. I believe it works great for losing stubborn belly fat as my friends have noticed a great loss in my abdomen area and in other smaller noticeable areas of my body. Which is kind of great since it has been a long time that I wanted to get rid of those. Furthermore, most notably though and focused in the stomach. I used to have a very big belly and it protruded out significantly. I don’t really drink heavily though that’s why it makes me wonder why I had it. However, I do notice while on it during my weight loss journey that it did sometimes cause minor weight gain by at most 2 pounds. But really, if you’re at least casually active, you should be able to work that off easily enough. I would recommend if you are a bigger person who may not be as big as I am or was would notice any significant reduction. It will probably take more time if you are already a leaner or fit individual according to my friends who are way, way lighter than me. At my current weight of 210 pounds, it has been harder and extremely slow to lose any more of my weight but I am trying hard to continue to lose the weight and slim down. After all, it has worked for me and I have proven it myself. So let’s keep ourselves posted guys. Once again, thanks Isaac!

  • I’m a 26 year old woman and I’ve been using this magical product for about 6 months now. I found this product online but was a little sketchy until Isaac wrote down his thoughts on it. This pushed me to purchase it doubt-free. When I started using it, I was at around 63kg. Now as of writing this, I am bouncing around 53kg. I couldn’t be more happier than this that I can maintain almost near my ideal weight. To top it off, I lost that much with minimal exercise and limited diet. I guess any pills will work best especially coupled with a healthy diet. I live on a tiny island nation with little to no access to healthy food so for me, maintaining to eat a healthy diet really needed a significant input of an effort which has been worthwhile so far. I started seeing definite changes to my form in the second month. Initially I did suffer from sleeping problems due to caffeine sensitivity. Normally, I don’t drink coffee even when I have to keep myself awake during midnight. However, 6 months later, it’s not so much of an issue now. My biggest sticking point is 4 times a day can be hard to remember sometimes. This is definitely not a joke. As far as I can remember, I probably have wasted my first month because I’d forget to take it later in the day… But overall, I’m happy with the results. I have more energy during the day, and losing those unwanted curves has motivated me to keep on doing strenuous physical activities.

  • Isaac has been my go-to when it comes to this topic. I started taking this pills not so long ago. I was going to the gym maybe 6 times a week before, but I was doing that before I started taking these pills. Definitely, I saw an impact when I ate sweet stuff. I had no idea why. To begin with, I did not even like the taste of it. Because of that, I totally stopped eating it. Also, for some reason, I always felt full. I noticed that my body fat percentage went from 23% to 19% over a 2 month period. Occasionally, I stop using this product because of limited stocks. Since then, I stopped taking them and noticed that my appetite has gone up a bit. But I do feel more controlled when it comes to eating sweet stuff. Would definitely take these again as a quick fix for a holiday body as they give energy during exercise and stop my uncontrollable cravings! Thanks Isaac.

  • I ordered this product a little hesitantly, after trying various products previously which all promised fantastic results immediately but rarely work, and instead saw myself gaining weight which I really hated. I found the price was not overly excessive, especially for a month’s supply. I was definitely sold on your thoughts Sir Robertson as you have always been honest with what you say. Initially not expecting much, I started on day one with my morning pill just before breakfast. Within ten minutes I felt full without taking a bite. This was rather strange. Naturally, I was a little surprised as I did not expect the appetite suppression to take effect so quickly. I continued throughout the course, sticking strictly to my diet and consuming the four pills daily. I have since started the same plan again to really pin down the difference on and off this wonderful product. All in all I would highly recommend this product to anyone struggling to stick to a plan. As much as discipline is important, a well-engineered product makes a world of a difference. I am glad I listened to this author.

  • I decided to try this product after trying several other products that failed my expectations. And after tons of research, I took the leap after I came upon this website. I am a new reader of Isaac but I have never read anything like this before. So I bought it immediately. Boy am I glad I did! I will admit the first couple of days I was on such a high, it was hard to sleep. I eventually got used to it and continued with my weight training. I eat pretty well so I really didn’t change my diet. I had increased energy, stopped eating out of boredom and felt so much stronger at the gym. I was on fire! Even after the first 2 weeks on this product, I saw results. I was in awe! If you are contemplating on trying it out I highly recommend it. Thank you Isaac for bringing out this product. You have really assisted me in reaching my goals.
