Before we get started, let’s quickly cover the points we assess when we are rating a test booster. We go quite in-depth in this site in individual reviews, but to sum up what we are evaluating;
• The Ingredients – What is in it, and what are the dosages. Importantly, also what is missing. • Price – Not just the cost but whether the product offers value for money or not. • Availability – It might be wonderful, but can you actually buy it anywhere? • Trust – You are putting these products into your body, can they be trusted? • Testimonials – What are others saying about the product • The Manufacturer – Who makes it, and what do we know about them.
The online world of supplements is a murky, shark-infested swamp of a place. We have navigated those swamps and dodged those sharks to bring you the best of the best.
Summary of Scores - Top 3 Fat Burners
Hydroxycut Hardcore Next Gen
#1 – Instant Knockout
Instant Knockout is an entirely natural fat burner from U.K based supplement company, Roar Ambition Ltd, which was originally developed to help get MMA stars into peak condition before a fight, but is now available for the general public.
Its list of premium ingredients is designed not only to safely burn fat, but also to increase physical energy and mental focus, allowing you to look and perform like the professionals it was first intended for.
The Instant Knockout Bottle is shaped like a fist, which is fitting because this product packs a serious punch. The ingredient profile is the best we’ve seen by some way.
The balance is damn near perfect, with powerful thermogenic ingredients green tea and cayenne pepper front and center to melt away those calories, supported by a sensible amount of caffeine to boost your energy and metabolism, and the best organic appetite regulation Mother Nature has to offer in Glucomannan fiber.
This quality across the board is what sets Instant Knockout apart from the competition and is what inspires so many impressive testimonials from users of all ages, both sexes and various physiques. This stuff clearly gets results.
Instant Knockout is only available from the official website and is a little more expensive than the average, but then again, its performance is anything but average, so we would absolutely say it’s worth a purchase.
The bar has been raised with Instant Knockout, our worthy champion.
#2 Shred Jym
Shred Jym is an all-natural fat burner from the range of supplements by respected former Bodybuilder, Jim Stoppanni.
It has two simple but desirable aims: to cut excess body fat, while boosting energy levels and allowing users to keep on working out.
Jim Stoppanni’s name on any supplement is a real mark of quality and most of the ingredients chosen here are effective and well dosed. Green tea and cayenne pepper are great choices as the main burners again, and there’s a healthy amount of caffeine too. Other organic stimulants such as Acetyl-L-Carnitine and L-Tyrosine are added to keep you really sharp and energized.
Shred Jym misses top spot because the strength of multiple stimulants may cause problems for users depending on their tolerance. Particularly as one of them is Synephrine – read more about that below. Suffice to say it’s only because we know the dosages in Shred Jym that we let Dr Jim off the hook.
Shred Jym also lacks anything to help with inevitable hunger pangs. Users are left to white knuckle it on will power alone.
#3 Hydroxycut Hardcore Next Gen
Hydroxycut Hardcore Next Gen is a popular natural fat burner from supplement company Muscletech, and makes up part of their impressive Performance Series.
A consistently strong seller since its release, the recently updated formula promises to deliver increased weight loss as well as extreme energy and mental focus.
Hydroxycut’s main players are green coffee bean and caffeine, two excellent choices for burning fat and increasing metabolic rate.
Natural stimulants are essential for losing weight quickly and with so much on offer here, we’re not surprised it gets results. If anything Hydroxycut is too focused on energy and metabolism.
Green coffee bean isn’t supported by any other thermogenic ingredients, no appetite suppressors are included and the stimulants are so potent that those without a high tolerance may struggle.
We’ve no doubt that all 3 of these will help you shed weight, it’s about how they do it and who that’s best suited to.
Hydroxycut Hardcore has some thermogenic qualities, no appetite suppressors and goes all out on the stimulants. You’ll reach your goal, but unless you’re made of stern stuff it could be a bumpy ride.
Shred Jym gives more attention to thermogenic ingredients but also offers no help with battling hunger and still goes big on the stimulants, which could be a shock to the system.
Instant Knockout is the best all round product. Plenty of thermogenic components, stimulant levels that won’t put a strain on any user and effective, organic appetite regulation.
Ingredients to Beware Of
As anybody who has read our reviews will know – there are many ingredients which have dubious clinical pedigree, or have been thoroughly debunked in tests.
If that was as bad as it got that would still be bad. It’s not as bad as it gets though, it gets much much worse.
Some of the ingredients you’ll find in fat burners and pre-workouts are outright dangerous. Encountering these ingredients is far more common than you’d think.
We’ve done a quick summary on some of the most common ingredients to watch out for:
DNP is old school. In much the same way that smallpox was old school. It was designated as ‘not fit for human consumption’ as far back as 1938, so we are not publishing some breaking scoop here by telling you it’s bad news.
Despite the dangers being known about for 80 years, unscrupulous people still sell it and unwitting consumers still consume it.
It can raise metabolic rate by up to 50%, and usage results in dramatic weight loss. But at a terrible price. It can cause severe overheating, dehydration, vomiting, a racing heartbeat and eventually death.
DANGER CLASS: EXTREME
Ephedrine has been in the news many times in the last few years, normally in relation to sports. It works by stimulating the heart, lungs and nervous system. The resulting increase in metabolic activity causes the body to consume calories and burn fat.
It is potent though, and taking it puts a huge pressure and strain on the body, even amongst healthy young people. Side effects of Ephedrine include strokes, heart attacks, tachycardia, seizures, paranoid schizophrenia, nausea, and vomiting
Whilst recent crackdowns have reduced it’s availability in regulated western markets, it can be easily obtained online from unregulated vendors in South East Asia.
DANGER CLASS: DANGEROUS
Aspartame is a synthetic sweetener which is widely used in the food industry. The place you are most likely to encounter it is in diet sodas but it also commonly features in flavoured powder supplements.
There are over 90 documented side-effects from aspartame, and it is estimated that over 75% of adverse reactions to food additives can be attributed to aspartame.
From depression and insomnia through to heart palpitations and even death, it can also worsen symptoms of serious medical conditions such as multiple sclerosis, diabetes and epilepsy.
Some nutritionists refer to aspartame as a ‘chemical poison’ (depending on the manufacturer a small percentage may even contain the poison methanol), and it’s not difficult to find reams of heated online discussion about it.
The bottom line is that there’s no reason to be using it – there are perfectly safe natural sweeteners and they are used in the best fat burners and best pre-workouts.
DANGER CLASS: MODERATE
Also going by it’s aliases bitter orange extract and citrus aurantium, synephrine is commonly found in fat burners and pre-workouts.
Synephrine isn’t necessarily dangerous on it’s own, the severe side effects occur when it is there in large dosages and combined with caffeine in large dosages. Which is obviously a problem.
Not only is caffeine use (and over-use) in the form of coffee consumption widespread and considered completely normal, many of these fat burners and pre-workouts which contain synephrine also contain large amounts of caffeine. So anything using a proprietary blend containing both synephrine and caffeine is an absolutel no-no.
Why? Because you have absolutely no idea hwo much of each you are taking.
When we say ‘severe side effects’ we are talking about heart attacks and death.
The link between synephrine and heart attacks / ischemic strokes was made as far back as 2005 following the case of a man who started supplementing with synephrine a week before his attack.
And in 2009 a legal case was launched by a 24 year old who suffered a severe heart attack after using Nutrex Lipo-6x, a fat burner which at the time contained a large amount of synephrine.
DANGER CLASS: DANGEROUS (with caffeine)
Also referred to as Yohimbine, this natural tree bark can assist with appetite suppression and is therefore commony found in fat burner supplements. There have been some very positive studies done on Yohimbe in relation to it’s ability in curbing hunger, and dosed correctly we here often treat it as a positive in a formula.
The trouble is that many manufacturers obscure the amounts they include in a ‘proprietary blend’ which means we have no idea how much of this is in the mix. Depending on your bodyweight there could easily be too much.
Consuming too much of it can cause side-effects such as gastrointestinal distress, anxiety and hypertension.
DANGER CLASS: LOW
tl; dr ... Short and to the Point
Who is this article aimed at?
Anybody who has spent countless hours trying to find a fat burning supplement which will work, is reasonably priced, and is produced by a reputable company.
I am busy - summarise it for me
The Shreditor's Choice. Yes, we really do have someone here called The Shreditor.
Despite some good ingredient choices, a few questionable decisions and poor serving schedule, combined with lukewarm customer reviews mean on balance we wouldn’t recommend Shred-Abolic Igniter, at least until they’ve ironed out a few of the problems.
There’s the basis of a solid fat burner here which just seems to veer off in too many directions at once.
Had they kept it a bit simple with tried and tested ingredients in the vein of green tea and caffeine it would’ve scored higher for us. Still potentially worth a punt if you’re willing to risk the more questionable choices.
There are certainly high spots you can pick out of LeanMode as a product. Natural choices, no proprietary blends with green tea and green coffee bean. The Acetyl-L-Carnitine may help some also.
But the good is balanced with some downsides. LeanMode is unlikely to help suppress your appetite despite what it may claim, and removing most of the caffeine really takes the edge off LeanMode's effectiveness
However understandable Nite-Burn’s lack of stimulants may be, the fact remains nearly all burners we review really struggle without them and this is no different. What’s less understandable is the lack of info on dosage and some highly questionable ingredients.
Nite-Burn is a nice idea, but one unlikely to deliver much in the way of results
A look at the exhaustive list of ingredients in Animal Cuts might make you think they've got everything you need for a great burner. That might be true, but the real question is, do they have enough of it in amongst everything else going on? Check our review to find out.
Burn-XT has what looks like a strong line up but dig a little deeper and you find it's not really making the most of what it's got. Our review takes you through the rights, wrongs and 'what's going on?'s of this Jacked Factory fat burner.
We really wanted to like Red Trim because it is one of relatively few fat burners which doesn’t use proprietary blends, but ultimately the ingredients just aren’t good enough and it suffers the same fate as most every other stimulant free options we’ve seen.
Aside from a possible energy boost, largely irrelevant.
