What are Fat Burners and how do they work?
Although it would be easy to answer this question with ‘they contain ingredients which increase your body’s capacity for fat burning’, the real answer goes much deeper than this.
That is because there are several different types of fat burners out there on the market, and depending on which type you use, they’re going to help your body burn fat in different ways.
Here’s a list of the most common types of natural fat burners:
- Appetite Suppressants
- Performance Fat Burners
- Stimulant-Free & Nighttime
- Carbohydrate Blockers
You’ve probably heard of a lot of these before, but may not know exactly how they work. Let’s clear all that up with a brief overview of each type:
In short, Thermogenics are ingredients that are used in fat burners for one purpose: to raise your body’s core temperature. A relatable example of this is spicy food, you feel the chili-based heat when you eat it, and after swallowing it you feel a lot hotter. In some cases you may even sweat.
So, why is this important for fat loss? Because it means your body has to cool itself.
To cool, your body use more energy than it does normally as it requires more effort to restore balance. More energy means burning more calories, this in turn boosts your metabolism which contributes to a caloric deficit and overall fat loss.
Notable thermogenics include Green Tea, Cayenne Pepper, and Green Coffee Bean.
These type of nutrients have a totally different approach when it comes to burning fat. Appetite suppressing ingredients are usually nutrients that are high in fiber, and low in calories.
Supplementing low-calorie ingredients that are high in fiber can help improve appetite suppression. The way they work is by swelling in your stomach after consumption which makes your body feel more full than it actually is.
The advantage of this is that you’ll want to consume less food throughout the day after taking it, which can make it easier for you to stay on your diet and keep progressive fat loss.
A good example of a high-fiber, low calorie appetite suppressant is Glucomannan.
Performance Fat Burners
These are the type of fat burners that you can use before going to the gym, as they are designed to help your with your workout. Essentially, they’re stimulant and cognitive based supplements with fat burning properties.
By having stimulants, these fat burners can help improve your overall energy levels and power output during your training sessions, whereas the cognition angle makes it easier for you to focus.
The best example of a natural stimulant found in these types of supplements are caffeine, whereas CDP-Choline boosts cognition.
Stimulant-Free & Nighttime Options
Rather than individual ingredients, stimulant-free/nighttime options are fat burning stacks which contain no caffeine or other stimulants.
They are supplements that are best suited to those who are very sensitive to caffeine or don’t require an energy boost. If you have any sensitivity to caffeine, or take a fat burner in the late afternoon or evening these are your best option.
Nighttime or PM supplements as they’re sometimes known also contain ingredients which can help promote sleep and recovery. A common choice in nighttime supplements are 5-HTP.
Carb blockers (also known as starch blockers) are very specific nutrients used in fat burners which can help reduce the amount of fat and/or carbs you have in your diet.
By not absorbing these types of foods, your body doesn’t get the calories from them, or the opportunity to turn them into stored fat.
So how do they work?
Blockers work by inhibiting the enzymes that are responsible for digesting that certain type of nutrient. They make it so your body can’t physically digest the carbohydrates in food. As natural ingredients, they’re not going to completely stop all the carbohydrates getting into your system, but they should still have an impact to help you reduce your stored fat levels.
A good example of carb blocker is White Kidney Bean.

How reliable are fat burners?
No fat burners are alike, and even if they were, their reliability would run deeper than just their ingredients.
Let’s unpack that sentence, a fat burner’s reliability depends on two things:
- The quality of the fat burner.
- How committed you are to fat loss.
That’s right, it’s not just the product that matters, how you use it matters too.
Why does the quality of a fat burner matter?
This should be obvious, if the ingredients and serving schedule are not effective, you’re unlikely to see results from using it.
What you want is a fat burner that has ingredients that are supported by studies show that they are effective at burning fat. There are plenty of great examples of effective fat burning nutrients in our previous question discussing how fat burners work, even the studies behind them are referenced.
However, if that is not enough for you, you’ll be pleased to know that we’re currently working on the best fat burner ingredients that work, as well as the worst ones in the industry.
When both of these articles are done, we’ll update this post with the links to both of them.
Why does my commitment to fat loss affect a fat burner’s reliability?
Because they’re not magical pills. Supplementing a fat burner doesn’t automatically guarantee that you’ll get six-pack abs, sculpted arms and a sub-10% body fat. You still have to work for it.
Fat burners aid the process by helping you to burn more calories and fat, but if you’re cheating on your diet every day and skipping the gym, you’re unlikely to see the results you’re looking for.
If you’re using an effective fat burner, you should still be training hard and dieting harder to make sure you’ll get the best out of using it. It’ll help take you that step further and see results you wouldn’t normally see training on your own.
What type of fat burner should I use while exercising?
If you’ve already read our first question in this article, you’ll have an idea of what type of fat burners there are out there on the market.
However, if you’re looking for a fat burner that you can take while exercising, we suggest you look into performance fat burners. As we’ve mentioned, these are fat burners that contain stimulants that caffeine that can help promote:
- Power Output
If these are the type of benefits you’re looking for, a caffeine-based fat burner is what you should be looking for. That would be your best option, either that or look into a fat burner that you like that you can safely supplement caffeine alongside.
It depends on the product, but caffeine-based fat burners have the best results when it comes to using it for the gym. If you have any further questions about a specific fat burner you’re looking at for this purpose, either let us know in the comment section or on the Contact Page.
Is it safe for a teenager to use fat burners?
No. Your body is still developing. We would strongly recommend against any teenager using fat burning supplements.
In some cases you’re still developing up until your early 20’s going on an intense weight loss crusade while you’re body is still growing could cause problems.
Who are fat burners for?
Fat burners help to increase your caloric deficit and burn more fat than you would do naturally, and work well with an effective workout plan and a healthy diet.
Generally, fat burners are for people who already exercise regularly and have the desire to reduce their body fat. They can do this by dieting, but they want results that will happen faster and potentially get their body fat lower than they could do naturally.
If you’re not exercising, simple changes to your diet and general nutrition can help you reduce your body fat. Fat burners would not be necessary.
So why can’t teenagers use them?
Cutting down to a lower body fat than usual could put unnecessary pressure on a growing body, especially a teenagers and could cause more problems than benefits.
If you’re a teenager, you should wait until your early twenties until you’re fully developed, and speak to your doctor on whether you should be taking a fat burner for your age.
Our editor, Doug, only starting using fat burners at the age of 23. Before that it was good old fashioned diet and exercise – along with the occasional protein shake.
How safe are fat burners in general?
It depends on the ingredients in the fat burner, due to the low levels of regulations surrounding these supplements, not all the ingredients are safe to consume.
This is why you should research every fat burner you look at purchasing it. As time goes on, we’ll write an article that covers the most dangerous ingredients out there – as for now, Google is your friend.
Good resources for researching ingredients:
- Examine.com – Huge nutritional database, covers most ingredients used in supplements along with their studies.
- WebMD.com’s Vitamin and Supplement Center – Less detailed, but a good resource for a second opinion.
However, the majority are. If you’re a healthy adult, with no pre-existing conditions you shouldn’t have a problem with a lot of the supplements out there however you should always check first, and consult with your doctor.
Can I lose weight without fat burners (and how)?
Yes. You can lose weight and burn fat without fat burners, they are not necessary if you’re looking to cut down your size – but they can help.
At some point we’ll be adding numerous extra ways that you can burn fat without the use of supplements covering diets and workouts which provide proven results.
In the meantime, here’s a brief list of ways that you can cut down fat in conjunction with exercise. Originally, this was an answer that I was intending to write for a question on Quora, but for now I think it’ll serve as a good starter guide to supplement-free fat loss:
- Caloric Deficit
- Intermittent Fasting
- Choosing your food carefully
- Effective Macro Ratios
Let’s look closer at those points, and find out how you can apply it to your diet.
1. Caloric Deficit
“A caloric deficit is any shortage in the amount of calories consumed relative to the amount of calories required for maintenance of current body weight (energy homeostasis). A deficit can be created by reducing input/calories consumed (lower food intake, aka dieting).” – Source Wikipedia
In short, eat less than your body needs to maintain it’s current weight, so it starts to burn into your fat stores.
If your weight hasn’t changed in a while – that’s probably a good sign that what you’re currently eating is your maintenance amount. Work out the calories on it, and then log it.
Next you want to lower the amount you’re consuming, don’t go crazy. I can’t give you an exact number of calories to cut because everyone’s maintenance amount is different.
Try a 15% calorie deficit for a few weeks and see where your body levels out. So for instance if you’re usually consuming 3,000 calories a day cut it down to 2550. The mirror will be the best judge of your body fat. You’ll know if you need to take it further.
The way it usually goes is you typically see great progress at first, and then it will start getting harder. But stick with it. Some people complain that caloric deficits don’t work – but that’s logically impossible.
Physiqonomics have an awesome article on this, it’s a funny read to:
- 8 Reasons You’re Not Losing Fat in a Calorie Deficit (Physiqonomics.com)
Section is TLDR; Less calories = More Fat Loss
2. Intermittent Fasting
This is optional, but I (Doug Brown, Editor here at Muxcle.com) find intermittent fasting to be absolutely amazing when I need to cut weight – but not for the reasons you might think.
What is it?
Intermittent fasting is when you choose to only eat at certain times each day. For example, only eating between 4pm and 8pm and then not eating for the other 20 hours and only consuming 0 calorie beverages over that time like tea or water.
It can help with getting your body into a fat-burning state when you go for longer fasts, and can also help manage blood sugar and pressure levels.
However, the research for it boosting metabolism looks promising, but nothing is confirmed yet:
That said, the main reason we recommend IF is that it teaches you serious discipline when it comes to food. Personally, I only eat one meal a day, with nothing but water and green tea in-between it.
Doing this allows you to balance your macros and calories into one big meal and stay strict on your diet. Results come fast.
Section is TLDR; Intermittent Fasting will force you to only eat a certain time. This allows you to plan your meal and take your set amount of calories. It’s a lot harder to cheat on your diet if you’ve decided you’re not allowed to eat for the majority of the day.
3. Choose Your Food Carefully
Keeping on track with your calorie goals is great – however, if you’re not picking your food carefully it can be absolutely hell.
You want to make sure that your body is getting all the right resources it needs to keep you being a healthy human, while still helping you cut down. I personally buy mixed frozen vegetables in bulk and have a huge portion with every daily meal. Here’s what the nutrition profile looks like for that:
- How Many Calories in Frozen Mixed Vegetables (Weightlossresources.co.uk)
You’re looking at around 50 calories for every 100g. You could have a kilogram of vegetables like this (2.2lbs) and still only be up to 500 calories. They bulk out your meals and they’re full of nutrients that your body needs.
If you need more ideas, WebMd have got some good ones:
One thing I will say is stay away from sugar. It’s the polar opposite of vegetables, it’s very high calorie and has essentially zero nutrients.
Take a look at the nutrient profile:
387 calories in 100 grams, 7.75 times more calorie dense that the vegetables I mentioned. That stuff is delicious, but it is absolute poison to your body.
So what should be eating besides vegetables? We’ll cover that now in the next section regarding your macros.
Section is TLDR; Eat healthy food which contains a lot of nutrients for your caloric restriction. It’s usually lower calorie so you’ll be able to eat more of it which will make dieting a lot easier. Also it’s good for you.
4. Effective Macro Ratios
Macros are also known as Macronutrients, these are your balance of protein, fats and carbohydrates.
To get the best results when it comes to fat loss, you want to strike an effective balance between them all which allows you to burn fat safely and effectively.
A lot of this depends on your body type. Some people are naturally bigger than others and their body stores fat in different ways. You need to work out which one you are – it’s not an exact science but it’s a pretty good guide.
There’s three main body types: Ectomorph, Mesomorph and Endomorph.
What are these? Let’s run through them:
- Ectomorph: This when you’re naturally a skinny person, with a smaller frame. You can eat a lot and your metabolism can help keep the weight off. Typically it’s harder for you to pack on mass.
It’s recommended that you have 25% protein, 55% carbs and 25% fat.
- Mesmorph: Naturally you’re athletic and muscular. It’s easier for you to cut fat, and pack on muscle when you need to.
For you guys it’s more 30% protein, 40% carbs and 30% fat.
- Endomorph: You’re naturally big boned and have a slower metabolism. Your body stores fat easier and it’s harder to shake off.
Finally, Endos, you guys should be on 35% protein, 25% protein and 40% fat.
That’s it in a nutshell. Obi Obadike (celebrity trainer and fitness machine) wrote a great article on this:
- Ask The Ripped Dude: Is There A Magical Macronutrient Ratio For Fat Loss? (Bodybuilding.com)
So what foods should you be eating? Here’s some healthy examples to get you started:
- Proteins: Eggs, lentils, cottage cheese, beef, Greek yogurt, chicken, tempeh.
- Carbohydrates: So many vegetables, nuts, seeds and whole grains.
- Fats: Avocados, cheese, coconut oil, macadamia nuts, fatty fish.
TLDR; Macros are your protein, carb and fat balance. How you split it depends on your body type if you’re looking for effective fat loss.
How safe is it to take other supplements with fat burners?
Most cases this is okay, but it all depends on the ingredients in your fat burner against the ingredients in the other supplement you’re taking.
In general we would say you’re fine to take most creatine, testosterone booster and protein supplements with a fat burner. Most of these supplements are usually designed with stacking in mind.
The main reason we believe you won’t have an issue is because they shouldn’t contain caffeine. When you’re using numerous supplements that contain stimulants, the tendency is for it to cause side effects.
You’re more likely to run into issues with pre workout supplements and nootropic stacks as they are known to be more stimulant heavy.
We would advise you to always read the supplement label first to ensure there’s no overlap. If you’re in any doubt, feel free to contact us or comment at the bottom of this article.
Should I take a fat burner on non-workout days?
Yes. Typically a fat burner comes in a month’s supply and you’re expected to take it every day. The advantage of this is that you’ll still be getting some benefit from it even when you’re not working out.
There are several reasons why it can help you if you’re not training that day. You just need to think about what a fat burner can do, and can that assist you if you’re not in the gym.
Does it contain appetite suppressants? If it does, that means it’ll be easier for you to stay on track with your diet that day.
Are there stimulants in there? If you’re on a low calorie diet, chances are you feel more sluggish and tired than you usually are. It can help keep your energy levels and focus up to keep you going throughout the day.
What about thermogenics? Well, burning fat is not a day-on, day-off procedure. If you want to cut down, you’re going to be doing something towards that goal every day. Thermogenics help you to burn extra calories throughout the day and will help you even if you’re not working out – although not to the same extent.
In short, you should still take fat burners on the days you’re not training.
Can I take a fat burner on an empty stomach?
This is question is particularly important if you stay in a fasted state throughout the day.
You should be able to take most fat burners without food, but always check with your doctor first. A good rule is to see if the fat burner contains any ingredients that are acidic.
Ingredients like D-Aspartic Acid, Beta-Alanine, L-Arginine are all acid based ingredients (fortunately, they’re more commonly found in testosterone boosters and pre workouts) these are more likely to give your stomach troubles if you’re not having them with food.
If the ingredients are all natural, and not acidic, you shouldn’t have an issue. Especially if it contains a fiber-heavy ingredient like Glucomannan.
However, you should always check with your doctor of healthcare professional first.
Which are the best and most effective fat burners?
Our views on this change all the time, the market is always releasing new products and we do our best to keep up.
If you’re interested what we’ve currently rated the best fat burners, the best fat burners for women, and the best non-stim fat burners you can read all about them in the links below:
- Muxcle’s Top Rated Fat Burners
- Top Rated Fat Burners for Women
- The Best Rated Non-Stimulant Fat Burners
All the information and our reasons why are in there.
What are the Best (and Worst) Ingredients in a Fat Burner?
This is something that we can’t answer in a short section like this. There’s far too much to cover.
At the moment, we’re currently putting together a list of each the best and worst ingredients on the market regarding fat burners.
They should be completed over the coming weeks, when they’re ready, we’ll update this section with the links to them.
What are you views on Amazon Supplements?
We do have issues with the supplements on Amazon, it’s too easy for anyone to sell on there – and to cheat the system.
What do we mean by this?
Although there are some great fat burners on Amazon, the same can’t be said for all of them. It’s those lesser products that we have a problem with, mainly because a lot of sellers have found a way to game the review system on Amazon to make their product rise to the top of the rankings.
We actually covered this in a huge 8,500+ word report, you can read the whole thing in the link below:
What should I be looking for in a fat burner?
Every fat burner is different, but there is a rough guide you can follow to help you pick out an effective fat burner. There are four main areas you should be looking at:
- Proprietary Blends
- Manufacturing Process
Let’s look at these points in detail.
1. The Ingredients – Are they good enough?
The main difference between a good fat burner and bad fat burner will always be the ingredients. If the studies aren’t there to support the content of a supplement, it’s not going to work for you.
If you’re serious about buying a good fat burner, you should read the label and make a note of the ingredients that are in the product you’re looking at – this goes for all supplements.
Your next step should be to research them online and make sure the studies are there to support the claims that have been made about them.
And of course, we’re always happy to help.
2. The Servings – How many are you getting a day?
This is another important factor. The amount of servings you’re getting a day can make a difference when it comes to how much of an impact a fat burner will have on you.
Think about how long a fat burner can be in your system. It’s an all natural product and typically passes through within a few hours. This is not enough to cover you for the full day, particularly if you’re using it as an appetite suppressant.
Ideally, you should look be looking for a fat burning supplement that is dosed well enough for you to take it 3 – 4 times a day. This allows your body to get a constant supply of the nutrients you need to keep you in that elevated state of fat loss.
3. Proprietary Blends – Why Should You Avoid Them?
This is one of the biggest sins in the supplement industry: proprietary blends. They demonstrate a complete lack of transparency, and highlight one of the major reasons for so much misinformation on supplements.
So, what are they?
Proprietary blends are when supplement manufacturers choose to hide the individual dosages of the ingredients in their product. Instead, all the ingredients are grouped together under one larger nutrient profile.
This is what we’re talking about:
You have no idea of any of the dosages of the ingredients in here. Notice how the supplement company in this example label their blend ‘Elite Class Thermogenic Matrix’, this distracts you from the fact that they’re not showing you the full story, and tries to market their lack of transparency as something specialist. This is not the case, do not be fooled.
Why do they do this?
The main reason is usually because they cut costs on the ingredients in their product and sacrificed proper dosages in the name of saving money.
Sure, it looks like there are several ingredients in there which could help fat loss, but without knowing how much there really is, means you don’t know how well it can work.
This allows the supplement manufacturer to use a very small amount of an effective ingredient for a cheaper price, while also allowing to market their product with a suggestion that the full amount is there to give you the full benefit.
It allows them to claim all the benefits for their product at a fraction of the cost.
4. Manufacturing Process – Is it all above board?
You should always be on the lookout to see if a supplement was made in a FDA and cGMP approved facility.
Thankfully most supplements are now, but there are still some out there (mainly those not produced in the US, UK or Europe) that aren’t.
Why is a facility having FDA and cGMP approval important?
Natural supplements cannot have FDA approval as they are not drugs. The next best thing that you can get is approval of the facilities that they are manufactured in.
What is the FDA?
This is the Food and Drug Administration. A body in the United States that ensure the safety, purity and security of food, drugs, medical devices and other goods available on the market. They’re an independent body that makes sure that what you put in your body is safe to use.
They inspect and approve facilities to ensure they are up to standard and give the consumer the safest possible product. You want to make sure that the place that your supplement is from has been tested under these standards and been approved.
What is CGMP?
This stands for Current Good Manufacturing Practices. It’s the standard set by the FDA that drugs and goods must be made to. Following these regulations ensures the purity, safety, quality and numerous other factors of the product being manufactured.
This is FDA’s way of protecting you from taking anything dangerous and ensuring that a manufacturer is making their supplement in the safest possible way.
For more information on the FDA and CGMP, check out the links below:
Do Fat Burners Fail Drug Tests?
It’s highly unlikely, but not unheard of. The ingredients that cause problems like this (and side effects) have been banned from over-the-counter supplements.
However, some are still in circulation. Always check the label first, and be aware of the following ingredients as they are currently banned from being in supplements:
- DMAA (1,3-dimethylamylamine)
If you’re curious about what other ingredients are banned from sports competitions, you can see the full list of what’s not allowed below:
- List of Drugs banned by WADA (World Anti-Doping Association) (Wikipedia.org)
We’re certain you won’t find those in a fat burner, but just to be sure, you should always check the label and see exactly what it is you’re getting. You can never be too careful.
