So you need to know just what they will do before you buy. We are not all the same either, so what may work for one person may not necessarily suit, or even be safe for, another.
Increasing your metabolism in order for your body to lose weight more quickly is one way that fat burners work, which can be achieved through stimulants like caffeine. Many fat burners use ingredients that cause thermogenesis, a process linked to the metabolism in which your body burns calories to produce heat.
Some boost energy levels and some can improve mood and mental alertness too, giving you an edge and keeping you focused.
Herbal ingredients can increase fat burning by flooding the body with healthy antioxidants and, although not all fat burners contain stimulants, some are so strong that they raise adrenaline levels – with potentially dangerous side effects for some people.
As you can see, there’s a lot to think about. No wonder choosing a diet pill can be such a confusing and stressful experience. We’ve done all the hard work for you though, so here’s everything you need to know about fat burners.
The big question you probably have is “which fat burner is the best?” Or “which fat burner should I buy?”
Well, this varies from person to person, but we’ve found a few that we think will work well for the majority of people. Let’s have a look at our favourites.
For us, the best fat burner currently available on the market is Phentaslim. It’s a strong but safe fat burner that is suitable for pretty much everyone; powerful enough even for bodybuilders, yet should not cause adverse side effects.
If you are looking for a safe and natural way to burn fat, increase energy and improve focus, Phentaslim ticks all the right boxes.
Optimum Nutra, the company behind Phentaslim, are very reputable and offer a money-back guarantee on all of their products, so you can buy risk free. It’s always a good sign when companies provide a guarantee; it suggests that they are so confident in their supplements that they’re willing to put their money where there mouth is and give you a full refund if you don’t like it for any reason.
The ingredients in Phentaslim are all backed up by clinical research, which is referenced on the website. This is another encouraging sign. We see plenty of products make bold claims with absolutely no supporting evidence, but you can actually check out the science behind Phentaslim for yourself before you buy.
The principle ingredient is green tea. Rich in antioxidants – called catechins, research has shown that when combined with added caffeine, it causes thermogenesis and fat burning that is more effective than either ingredient when used alone. So you’ll be glad to hear that Phentaslim also contains 190mg of caffeine (roughly the equivalent of two cups of coffee), a safe amount that is still strong enough to work. This combination is improved further when used with resistance exercise.
Other herbal ingredients include Panax ginseng, a well known adaptogen that helps the body manage stress, cayenne pepper for added thermogenesis, and black pepper extract, which will improve the bioavailability of the other ingredients, including the vitamins and amino acids contained in Phentaslim. All servings are in safe but effective quantities that compare well to vitamin supplements.
Side effects are unlikely, unless you are sensitive to caffeine. Even then, Phentaslim contains L Theanine, an amino acid with a calming yet energising effect that is known to smooth the sometimes jittery effects of caffeine.
According to Optimum Nutra, this product has sold in its thousands, and the customer feedback that we have seen is overwhelmingly positive.
You can only buy Phentaslim from the official Optimum Nutra website, where shipping is free of charge and available worldwide. The prices are pretty good as fat burners go, particularly as you can make savings on multi-bottle orders:
Another favourite of ours is Hunter Burn, which offers a way to burn fat, beat hunger and build muscle. It is advertised as a fat burner for men, but contains extra ingredients to target other issues of weight loss, including appetite suppression.
There are six key ingredients in Hunter Burn. The fat burning firepower is provided by matcha green tea and cayenne pepper. Matcha tea is a good quality green tea that is higher in antioxidants than other green teas, so there should be a powerful fat burning effect based on this alone. There is no added caffeine beyond that which is naturally contained in the tea, so this supplement could suit you even if you are sensitive to stimulants.
The principle ingredient is glucomannan, a natural fibre based on Konjac, which is approved by health authorities as a safe appetite suppressant. Hunter Burn contains the clinically approved serving of 3000mg a day. When taken before meals, this dosage will reduce hunger pangs and appetite.
Other ingredients include white bean extract (a natural carb blocker), vitamin D, and the amino acid L theanine, known for its calming but energising effect. All of the ingredients contained in Hunter Burn conform to clinical testing and is referenced on the official website.
There is not a lot of customer feedback currently available as Hunter products are fairly new on the market and are only sold via the official website, where there is no platform for customer comments. However, there is a money-back guarantee that is valid for 90 days, so you can try it risk free and get a full refund if it doesn’t suit you.
Another positive: Hunter Burn looks to be pretty safe, as side effects are likely to be minor. One thing we would note, make sure you take this supplement with plenty of water because glucomannan is a fibre that expands, so it needs to be safely in the stomach before it does this to avoid the risk of blockage or choking.
One bottle of 180 capsules (one month’s supply) costs £55.00. Two month’s supply (two bottles) costs £110.00, including free UK and free US shipping. And four bottles costs £165 – this also includes free shipping to the UK and USA.
So there you have it, Phentaslim and Hunter Burn are our picks for best fat burners. But you might still have a few burning questions about diet pills in general. So what else might you need to know? Let’s answer the most common questions we see about fat burners.
For the most part, the best fat burners for men will be exactly the same as the best fat burners for women, as they should contain clinically proven levels of safe ingredients for everyone.
Fat burners targeted at men usually mention strength and bodybuilding, whereas female focused supplements sometimes use words like “slender” and “dress size”, but other than that, there really shouldn’t be any difference. This way of marketing is pretty common, but not all men want to lift weights and not all women are hoping to avoid the gym. Most people just want to lose weight to feel healthier and look more attractive, and are looking to find the way that suits them best.
A good quality fat burner will contain ingredients to increase the metabolism, regardless of gender. For example, green tea and caffeine is an effective combination for fat burning. Many supplements also contain additional herbal extracts, such as Panax ginseng or vitamins and minerals, which will be suitable for everyone. These additional ingredients can often make the whole weight loss process easier as well as helping to improve health and energy.
Sometimes though, fat burners aimed specifically at men can be quite strong and cause side effects. T5 supplements, which are supposed to boost the thyroid, are often aimed at men, for example, as are supplements with macho names and containing lots of stimulants. But this doesn’t mean they can’t be taken by women. If anything, we would recommend that everybody avoids the fat burners that have associated risks, no matter what the positives may be.
There is, however, one type of male focused fat burner that is not suitable for women, and that is one that boosts testosterone. Anything related to hormones is likely to be directed solely towards one or the other, as hormonal profiles are incredibly different between men and women, with a much higher potential for problems if taken by the wrong sex.
We always say it, but you must check through the ingredients list before you buy, so you can ensure that the supplement is right for you.
As we’ve seen above, companies often target specific people with their products, with many fat burners in particular being aimed at women. These range from the ultra feminine and girly type of product that promises a reduced dress size and comes with some cutie style pink advertising, to the more hardcore bodybuilder fat burner that shows women working out in the gym.
The truth is that none of this really matters. The important factors are that a fat burner comes with full ingredients information and it contains a decent range of components that actually work.
The same fat ingredients that work for men work just as well for women. Green tea and caffeine are effective, especially when used in combination. Some products contain stronger stimulants to create an even more powerful effect, but this usually means a higher risk of side effects as well.
Sadly, we have noticed that many female orientated products don’t provide any basic information, which makes us pretty mad. It seems that some manufacturers just don’t bother with basic facts when advertising to women. You should avoid any fat burner that does not explain exactly what it contains.
As we’ve mentioned, the vast bulk of fat burners can be taken by either men or by women. However, you do need to read through the ingredients list carefully because some fat burners can contain ingredients that affect hormones and will not be suitable if you have, or have had, a hormone-related medical condition such as breast cancer. In a similar vein, fat burners that have testosterone-boosting ingredients should also be avoided by women.
You should never take fat burners if you are pregnant or breast feeding either. Firstly, because this is not the time to lose weight, and, more importantly, there may be a risk of side effects to your baby. If you are trying to conceive, be careful not to take anything that may increase the risk of miscarriage. Some herbal extracts are otherwise safe but are known for this effect.
Just because a fat burner is strong, it doesn’t mean it’s necessarily worth taking. In some cases, a supplement with supposedly strong ingredients may just contain a lot of stimulants, and there are serious health concerns about some of these.
But there are plenty of strong legal fat burners on the market that will be safe for most users. For example, green tea and caffeine is a safe and effective combination. The ingredient quantities should be strong enough to work yet not cause too many adverse effects. But this is sometimes a fine line, and one that many companies play fast and loose with – and sometimes ignore completely.
Ephedra is a perfect example of strong but dangerous. It’s a herbal ingredient that was commonly found in fat burners until it was banned after being linked to causing deaths, heart attacks and strokes. Despite this, people still actually search out a legal equivalent. There are some strong fat burners that still contain dangerous stimulants that are no safer than ephedra but are currently legal.
A weight loss supplement that is high in stimulants that mirror the fight or flee response and increases adrenaline levels can help curb appetite and send energy levels soaring. Ingredients that do this are known as sympathiometic agents and include synephrine, hordenine, bitter orange extract and yohimbine. In a similar way that amphetamines work in the body, these stimulants can cause weight loss by making you feel too stressed to eat. The immediate boost to energy levels can also help you perform well in the gym. But there is a major downside to taking these types of strong fat burners. Side effects can be dangerous, especially as they increase the heart rate and blood pressure. Many people report numerous side effects and, according to clinical research, they are not always effective at causing long-term weight loss.
In general, most fat burners are not dangerous. Although some contain caffeine, a supplement based on natural ingredients can be taken by most people without causing any side effects or issues to health. We’ve mentioned it a couple of times already, but it really is worth repeating: it is always important to read through the ingredients list beforehand and to only buy from a reputable company.
Caffeine is well known to us all and is a mainstay of many fat burners. As a rough guide to caffeine strength, an average cup of coffee contains around 100mg of caffeine per cup. Many fat burners contain around 100–200mg of caffeine per serving, which is not going to be a problem unless you are caffeine sensitive. It may also feel stronger in capsule form than drinking in coffee.
Not all caffeine is safe though, and high levels (over 400mg a day) can cause side effects for some people. Watch out for fat burners that contain a potent variety called caffeine anhydrous too, as this can feel much stronger than usual caffeine and lead to jitteriness and insomnia.
Then there are the fat burner supplements that contain potentially dangerous stimulants. Look out for the the names synephrine, bitter orange extract, citrus aurantium, or yohimbine on the ingredients lists. Even these may not be a problem for everyone, but they should definitely be avoided by novices or anyone who has an underlying medical condition, such as high blood pressure or heart problems. To be completely honest, we don’t think anyone should risk taking products that include any of these ingredients, it just isn’t worth toying with your health.
Sadly, there are imported supplements on the market which come from unregulated countries, such as China. We would urge everyone to avoid these because they are notorious for containing unlisted and dangerous chemicals that are banned in most countries.
We’ve even seen some companies bragging that their products still contain banned substances! The selling point is that they are stronger than normal fat burners, but all we see here is danger. An ingredient will have been banned for good reason. On the plus side, you have to actively search for these types of supplement, so you are unlikely to buy them by accident.
The most common type of fat burners are what we call thermogenic. These products put your body into fat burning mode.
Thermogenesis is the natural metabolic process that your body uses to generate heat. It does this by burning off the calories stored as fat, and thermogenic fat burners look to increase the amount you burn.
There are three main ways to put your body into thermogenesis.
The first is exercise, as this causes sweating. When you exercise, your muscles use calories for fuel and energy. Although the muscle contractions use the most calories, sweating and the generation of heat (thermogenesis) also burns them. Increasing your metabolism and thermogenesis are not exactly the same thing, but both metabolic functions are closely linked.
The second way of inducing thermogenesis is by your environment. Cold temperatures cause thermogenesis because your body shivers to produce heat, again using up calories. This is not a fun way to lose weight, but next time you are shivering just remember you are burning off a few extra calories.
The third way is through diet, which is where thermogenic fat burners fit into the equation, as some food stuffs naturally cause thermogenesis. Thermogenic ingredients include caffeine, green tea, and red capsicum peppers. Research has found that ingesting these natural substances can boost fat burning and increase your metabolism.
Taking a thermogenic fat burner supplement can be much more effective than adding thermogenic foods to your diet because a supplement contains higher quantities of the thermogenic substance. Like with green tea, where the fat burning effect can be pinned down to antioxidants (ECGC, that’s epigallocatechin-3-gallate, and polyphenols) that have anti-obesity and fat burning properties.
Thermogenic fat burners help maximise your weight loss and most provide the added advantages of supporting your general health and energy.
The safest fat burners contain tried and tested ingredients. Thermogenic ingredients like green tea, caffeine, and red pepper all help the body burn fat and increase the speed of the metabolism. So a fat burner that contains these ingredients in the correct quantities will be safe and effective for most people.
Many supplements also include vitamins and minerals that can provide general support to health and weight loss. Amino acids such as L Tyrosine can improve muscle building and alertness, and some herbal extracts are useful for improving mood or general health.
There is a wide array of herbal extracts used in weight loss supplements, so it is important to look at the ingredients list to check this out before you buy. Again, most of these will be safe for the majority of people but you can’t guarantee that a supplement will work in the same way for absolutely everyone. We are all different and have different tolerances and sensitivities.
Although many fat burners state that they only contain natural ingredients, this does not always mean they are safe. Some natural ingredients can be very dangerous, especially if taken in high quantities, and can sometimes cause serious side effects. For example, yohimbe can be extremely dangerous, yet is a naturally derived chemical from a West African tree. Other less well known herbal extracts can cause unpredictable side effects too, so if you are unsure of a certain ingredient, or have never heard of it, make sure you research it first.
The most effective fat burners contain ingredients that increase the metabolism without adverse effects. So a good fat burner needs to be strong enough to work but if it is too heavy in stimulants, for example, many people will be unable to take it because of side effects. Taking stimulants on their own is not good for health and will leave most people feeling wired and jittery.
A good fat burner will hit the sweet spot between effective and too strong. Natural ingredients like green tea and cayenne pepper work well, but some added caffeine will improve results. Clinical testing has identified green tea paired with caffeine as an effective fat burning combination; they actually work better together than either taken on its own.
Natural caffeine is a better choice than caffeine anhydrous, even though the latter can be much stronger. An ultra strong caffeine hit may well be good for energy and weight loss, but if it is too strong it can cause side effects such as nausea, jitteriness and insomnia.
We like to see some added health ingredients included in fat burners too. Various vitamins, minerals, and amino acids can support weight loss and make the whole process easier. A good example is the amino acid L Theanine, as this can smooth the effects of caffeine – so if you are sensitive to stimulants, this ingredient may help reduce some of the jittery symptoms.
So many people feel that their belly fat is the one area where they need to lose weight. No matter how reasonable your size and weight otherwise, there it is – an unsightly and unhealthy spare tyre of fat around your middle. Men and women both suffer from the same problem.
This isn’t really surprising, as this is the area where weight is put on most noticeably. And on the flip side, when the weight starts to drop off, this is where you will probably see results first.
Despite this noticeability, you can’t actually spot reduce fatty areas. Weight loss supplements and diets help you lose weight everywhere; you can’t decide which part of your body to slim down. Your fat tends to reduce all over, keeping the body in proportion.
Lifting weights can obviously build and tone specific muscle groups, but you can’t lose belly fat by doing exercises on your stomach – you need to actually lose the weight to make it go away. Strengthening muscles and becoming fitter will help build inner core strength, but that six pack will only show up once you’ve lost the body fat on top of it.
Although there are thousands of fat burners on the market containing a wide range of ingredients, when it comes to proven clinical evidence this list suddenly becomes a lot smaller.
Green tea is one of the most common ingredients, and also one of the best. This type of tea undergoes less processing than ordinary black tea and contains high levels of antioxidants called catechins as a result. Evidence shows that catechins directly increase the speed of the metabolism as well as heightening thermogenesis – a bodily process that increases heat, causing more calorie burn.
Caffeine is also a natural fat burner. Caffeine increases the speed of the metabolism, is a natural thermogenic, and increases energy levels. Countless studies show that when combined with green tea extract, the ingredients have a much stronger effect than either taken alone, so a fat burner that mixes caffeine with green tea is a real winner.
Capsicum extract is another natural thermogenic. This increases body temperature and provides an extra metabolism boosting effect. Capsicum is safe and well tolerated, so is unlikely to cause any side effects.
There is green coffee extract too, which is rich in antioxidants and chlorogenic acid. This has lower levels of caffeine than regular coffee beans, so it may suit you if your caffeine tolerance is low. Matcha green tea is another one with lower levels of caffeine, and is higher in antioxidants than regular green tea, but still has a fat burning effect.
Black pepper extract is not a fat burner but it can increase the absorbency of other ingredients, making it a worthwhile addition to any fat burning supplement.
Yes, fat burners are legal. You won’t break any laws by taking or buying a fat burner. This type of supplement is taken by thousands of people each day as a support to weight loss. If you are new to supplements it might seem an unknown step, but once you do it you will realise that the sole purpose is to help you lose weight more easily and improve your health.
That said, there are some ingredients that are illegal to include in products, but it’s the company that will get into legal trouble for selling it, not you for buying it. Although it should be stressed that a banned or illegal ingredient will cause health troubles for you if you take it. So make sure you only buy from a reputable seller, that way you can be sure that your fat burner is safe and does not contain anything dangerous.
Sports people, athletes and bodybuilders often have concerns about supplements and how they relate to drug testing. Fat burners are not usually banned in sporting events, but you should check through the ingredients list before you buy, as some of the ingredients can be prohibited by various organisations.
As an example, some fat burners contain Citrus aurantium (also known as bitter orange extract), which contains the stimulant synephrine, and some athletic associations, including American College Leagues, consider this a banned ingredient.
Less common, but occasionally added to supplements, octopamine is banned by the World Anti-Doping Agency (WADA), as are illegal supplement ingredients containing ephedra. Ephedra was once legal in weight loss supplements until it was banned in 2004 because of its links to side effects like heart attacks and stroke.
Thankfully, the vast majority of supplements on sale are perfectly legal and will not get you banned from competitive sport. Again, always check out the ingredients list before you buy, just to be sure.
We all know that losing weight can be hard work. Although we usually start off full of good intentions and enthusiasm, after a few days or weeks it can be difficult to stay on track and get motivated. A fat burner can make the whole process much easier though, by speeding up weight loss and helping you feel on top form.
When buying a fat burner you need to know what to look for. A supplement that contains optimum quantities of proven ingredients, powerful enough to work but not too strong to cause side effects is the key. As Goldilocks said about her porridge – it has to be just right!
The price is important too. Nobody wants to waste money, so you should really look for a product that is covered by a money-back guarantee, that way you are protected and get a full refund if the supplement doesn’t work for you.
Sadly, the weight loss industry is somewhat unregulated and there are some scammers out there. To keep your money safe, never sign up for a free trial program. These types of promotions are always scams and you will find yourself tricked out of money. Never sign up to an auto-ship agreement either – this is where a company promises to send you fresh supplies of the product each month. If the supplement works as described, you will not need to take it on a permanent basis. These types of auto-ship schemes can be very hard to cancel.
A good quality fat burner is certainly worth it, but you may have to shop around to find the supplement that you can buy in complete confidence. Of course, we’re here to help you do just that.
Fat burners are generally safe to use but, as we keep repeating, you have to check through the ingredients before you buy, because not all fat burners will suit everyone.
The fat burner should contain tried and tested ingredients. Quantities are crucial too – each ingredient should conform to the clinical testing; it should be powerful enough to work, but not so strong that it causes lots of side effects.
The side effects can also vary from person to person. Caffeine, for example, is a safe and well-tolerated stimulant for most people, yet for others it causes jitteriness and insomnia.
Green tea and green coffee bean extract are generally safe for everyone. Cayenne pepper does not seem to have any particular issues either. But the bottom line is that anything can cause a reaction in certain people, even the usually safe ingredients.
The best approach when trying a new fat burner is to start with a very low dose so that you can see how it affects you before you try the full serving. This keeps any potential side effects to a minimum. A good quality fat burner will explain the risk of any potential side effects before you buy.
Make sure you choose a fat burner that comes with a full money-back guarantee too, as this will enable you to get your money back should you find the supplement does not suit you.
The best way to lose fat fast with a fat burner is to combine it with added exercise. You don’t necessarily need to sign up at the gym and start lifting weights, but getting more active will certainly speed up your weight loss results. This is all down to the metabolism. A fat burner increases the speed of the metabolism in order to cause faster weight loss, and your body does the same thing naturally when you exercise.
You might think that the way you lose weight through exercise is just by burning off some of the calories that you eat, but another feature of physical activity is that it increases your metabolism too. This is not permanent, but your metabolism is increased for as much as 24 hours following a 30-minute workout. Walking, running, swimming, or even just doing the gardening or housework, it all counts as metabolism boosting exercise.
If you combine added exercise with taking a good quality and effective fat burner, your results will improve. Your fat burner will help with exercise performance and keep your metabolism burning fast, even during the periods that you’re not doing anything. Clinical studies have shown that using green tea and caffeine in combination is one such way to improve weight loss results from exercise.
While a fat burner does work better with added exercise, you don’t have to go mad. The type of activity you choose will depend upon your own levels of fitness, and any improvements to your lifestyle will get your weight moving in the right direction.
If you are new to the world of supplements, buying a fat burner can be a daunting prospect. There are so many weight loss supplements on the market advertised as fat burners that it can be hard to choose the right one for you.
The best fat burners show the full ingredients information and include effective servings of proven ingredients. Green tea extract and caffeine is research-backed weight loss combination, for example. Cayenne pepper and green coffee bean extract are also worthwhile ingredients.
Many fat burners offer more, beyond simple fat burning. Plenty of products include additional vitamins and minerals, amino acids, or herbal extracts that can help improve mood or decrease appetite. Although the fat burning part of the formula is the way that the supplement works, other ingredients can help make weight loss easier or have an effect on your general health.
A good quality fat burner will also come with an explanation about how it works and provide clinical evidence that the claims for the ingredients are actually backed by science. If a product doesn’t show the hows and the whys behind it, then it’s not worth risking.
Despite all this, a fat burner is not a magic diet pill. The best fat burner in the world will not work overnight or cause rapid weight loss in a matter of days. And as with all methods of weight loss, you do need to make some changes to diet and lifestyle and stick to them.
According to the NHS, the recommended rate of weight loss is no more than 2lbs a week. This doesn’t sound much if you have a lot to lose, but stick with it for a month and 8lbs weight loss in 4 weeks is certainly noticeable.
Fat burners and exercise work best when they are used in combination. You are unlikely to lose much weight if you just take your capsules and then sit back and wait for the weight to roll off. Likewise, while upping your activity levels increases the speed of your metabolism, pair this increased activity with a fat burner and you will certainly lose weight.
Fat burners are not all the same though. Ingredients and quality can vary, but there are some very good supplements out there to help you on your way.
Some key tips to bear in mind: To stay safe and to make your experience a positive one, always look for a reputable product. Check out the ingredients so you know exactly what you are taking. Don’t go for a fat burner that is aimed at bodybuilders and athletes if this is not you. Too many stimulants in a supplement may seem like good value for money, but side effects can be an issue and, in some cases, a serious risk to health. A supplement that works safely will support your weight loss long term and will not cause dangerous side effects or make you feel ill.
If you are a man, don’t be put off by a fat burner that seems to be aimed at women. The same is true for women who may be reluctant to buy a supplement that seems more manly. The best supplements are not gender specific anyway, and do not resort to tired old sexist clichés in order to sell products.
The worst part about buying supplements, or buying anything online really, is that there are companies out there who try to rip you off with inferior or even dangerous products. When it comes to buying something that you have to put into your body, you need to be able to trust it will work without it being a danger to health. In our opinion, a fat burner based on proven natural ingredients from a reputable company is the safest option.
A money-back guarantee is also a good sign that the supplement and the company can be trusted. If you do not like your chosen fat burner and feel that it isn’t working for you, it should be easy to get a refund. You should be able to buy in confidence.
Losing weight can be hard, especially when you start, but a decent fat burner will kickstart your plans. Whoever you are – man, woman, athlete, office worker, retired, busy mum, coach potato, or anything else – a quality fat burner has something for everyone and will support you on your weight loss journey.
