Everything You Need To Know About Fat Burners

Fat burners are popular in the fight against excess weight.

These supplements are formulated to boost metabolism and energy, which help increase your body’s thermogenesis.

So you’re probably wondering do they actually work, and if so, are they are safe to use?

  • Fat burners use stimulants to alter hormonal reactions and boost metabolism.
  • Your metabolism is the chemical process that keeps your body functioning correctly.
  • A faster metabolism is crucial for weight loss – your fat stores become a source of energy.
  • Some products include ingredients to improve your mood and promote focus.

By increasing metabolism, a fat burner can help weight loss by getting your body to use stored fat as an energy source.

As with any other weight loss supplements, they require discipline to work effectively. For the best results, they should be combined with an improved diet and some exercise.

They’re not for everybody, but a fat burner could be ideal if it suits your needs.

Q&A: Fat Burners

What is a fat burner?

A fat burner is a common type of diet pill.

They help you to ‘burn’ fat by boosting your metabolism using active ingredients not easily sourced from food intake alone.

Using natural, stimulating ingredients, they work to create hormonal reactions to get your body to use your fat as an energy source.

Your body could do this naturally without a pill if you follow a strict diet and do moderate exercise. This is easier said than done for many people.

Using a supplement can make this easier, kick-starting the process much sooner.

Many fat burners contain caffeine as their main stimulant. Caffeine increases metabolic rate to use calories much quicker.

Like other weight loss supplements, fat burners require discipline to work effectively. It’s not enough to just swallow a pill and expect weight loss to happen. It doesn’t this way.

If you are overweight and don’t change your lifestyle, a diet pill will make little difference.

To get the best results from a fat burner, you should make adjustments to any poor dietary choices. If you’re not active, you should consider starting some exercise.

What are the benefits of fat burners?

  1. Fat burners can speed up weight loss by increasing metabolism.
  2. Some products help improve mood and general wellbeing.
  3. They encourage a healthier diet and lifestyle.
  4. Suitable to take for the majority of people.

What are the negatives of fat burners?

  1. Stimulants are not suitable for everyone.
  2. Of little use to those with mobility issues.
  3. Some cheap products can be dangerous.

Do fat burners work?

Fat burners can work for weight loss when used correctly.

No supplement can circumvent a lazy lifestyle or poor diet. For a better chance of success, you need to address the reasons that caused your weight gain in the first place.

Fat burners can provide an energy boost many people find encouraging. It can trigger the urge to go for a brisk walk, or even a light jog, which will further your weight loss.

A fat burner will work to raise your metabolic rate.

Someone with a faster metabolism will be less prone to weight gain. Throw in some exercise, and a fast metabolism will first burn through excess calories before converting stored fat into energy.

Fat Burner Best Results:

  1. Make better food choices. Eating sugary food or starchy snacks all the time will just slow down or prevent weight loss.
  2. Reduce your calorie intake. No pill can negate the effect of excess calories. If you keep eating too much, you won’t lose weight.
  3. Start doing some exercise. Using a fat burner and then sitting around watching TV is just a waste of time and money. Make better use of your improved metabolism and get moving.

Are fat burners safe?

For most people, yes they are.

Many fat burners are formulated from natural, tested ingredients, and are safe for the majority of people to take.

But you do need to be particular about what and where you’re buying your products.

Cheap Chinese imports are a big risk. You’ll often find these pills on sites like eBay and Amazon, and their low prices can be tempting.

Chinese supplements are unregulated, and made in factories that are not inspected. The quality of the ingredients isn’t guaranteed, either.

Buying pills made in China is like playing Russian roulette with your health. It’s really not worth the risk.

Countries such as the UK and US have much tighter rules. Products are manufactured in clean, inspected facilities. Any required warnings must be printed on the labels.

Most natural substances are harmless but could affect other medications.

If you are taking prescription medicines, you should consult with your doctor first before taking anything new.

What are proprietary blends?

So, you’ve found a great looking product and what to find out more.

Looking at the label, you see it says something like ‘proprietary blend’, or some fancy word with a trademark symbol next to it.

What these mean is the manufacturer doesn’t want you to know what’s in the product.

Why not? Maybe some product makers are paranoid, and think other companies will steal their formula if they reveal it on the label.

Or, it could be their product is full of cheap ingredients they don’t want you to know about? Or isn’t what they say it is in their marketing.

Either way, it’s your body. You need to know what you’re putting into it. You might have an allergy or sensitivity to the undeclared ingredients.

Proprietary blends are a load of nonsense.

You should avoid taking any product that won’t tell you exactly what’s in it.

What to look for in a fat burner.

You’ll discover fat burners contain a wide variety of ingredients, and no two products are the same.

Below are some of the most effective, natural ingredients used in fat burners, and are what you should look for.

Spices on spoons

Panax Gingseng: Used as a herbal medicine for general health for thousands of years in Asia.

Modern research points to its antiobesity properties. It can have a positive effect on gut bacteria, and clinical tests show weight loss can be achieved within a 12 week period.

Additionally it can decrease fatigue and anxiety, and improve the immune system.

Green Tea: Made from Camellia sinensis leaves and buds, green tea is an excellent source of antioxidants and nutrients.

These nutrients can contribute to general health. They can increase brain function and help aid heart health.

For weight loss, research shows green tea assists in raising metabolism.

Caffeine: A natural stimulant widely found in tea, coffee, and chocolate.

It’s actually classed as a psychoactive drug, though it’s legal and used worldwide.

It’s known for providing energy and alertness. Too much caffeine can cause some short-term side effects, such as feeling jittery or light headed.

L-Theanine: An amino acid that provides a range of health benefits, including improved mental focus and better sleep quality.

Further research indicates it can promote relaxation without causing drowsiness.

Capsaicin: A powerful chilli extract noted for its ability to burn fats by raising thermogenesis. This is the active component that gives chillis their heat.

It can be an irritant if used incorrectly; for weight loss it’s best taken orally as part of a pill.

Belly fat creams containing capsaicin, for rubbing on your belly, will not do anything other than make your skin tingle and turn red.

Losing weight with a fat burner

A good fat burner can help you lose weight.

Using a supplement to increase metabolism will help burn calories faster and improve overall wellbeing.

Your metabolism is the process that keeps your body functioning. Breathing, sleeping, and digesting food are all controlled by metabolism. Each of these everyday processes requires energy.

If you are active and fit, your metabolism will work faster and better. Your appetite will function correctly, your sleep will be of high quality, and your general day to day life will not feel like hard work.

Those with a faster metabolism are also less prone to weight gain.

Weight vs Metabolism graph
For those of us who are out of shape and overweight, our metabolism will have slowed.

Slow metabolisms will crave the bad foods, simply for the quick release energy (think biscuits), and our sleep quality will be diminished.

Getting metabolism up to speed is crucial. This is where using a fat burner can prove to be a key component.

Throw in some light exercise and an improved diet, and you’ll be making progress in no time.

NHS England says a sedentary lifestyle is dangerous for health and a major contributor to obesity, diabetes, and heart disease.

Three things worth avoiding, you’ll no doubt agree.

Know Your Metabolism

Fast Metabolism
Very active people, such as athletes. Eat the foods most suitable for their needs. Considers fruit a dessert – yawn.

Normal Metabolism
This is where most of us should be. A good diet with occasional treats. Light to moderate exercise daily – walking to work counts (though not if work is just the next street away).

Slow Metabolism
Those of us who are not active enough. Prone to making poor dietary choices – hello, entire family bag of crisps, gone within half-an-hour.

Who are fat burners for?

Fat burners can work for almost anyone.

If you’re wanting to lose some weight and gain some energy at the same time, a fat burner will help.

For people already in shape, a fat burner can contribute to maintaining a stable, healthy weight.

For those who already exercise, a fat burner can provide a boost to push you further. A fat burner will not ‘burn’ muscle, as they target excess fat and water.

But, for those who just want to take a pill and expect to lose weight, a fat burner will contribute little.

For those who are not mobile, a fat burner isn’t the best choice of supplement – an appetite suppressant could be more suitable.

To get the best results from a fat burner you really need to combine them with an improved diet with some exercise.

Convenient 2-in-1: Hourglass Fit


Hourglass masquerades as both a fat burner and an appetite suppressant. It is possibly a master of neither.

There is a danger of style over substance here. The packaging is feminine and appealing. The website marketing is strong and professional.

Underneath all this sheen, what you do get is a good combo product, with some caveats.

It contains glucomannan but nowhere near enough; just half of the suggested daily intake. For appetite suppression, you’ll need more.

Hourglass contains stimulants to power up metabolism. This makes it great for the casual gym-goer, or somebody looking to shift a smaller amount of weight.

For convenience, Hourglass scores highly. For effectiveness, it would be better to buy a dedicated fat burner and separate appetite reducer.

One to avoid: XLS Medical Max Strength

XLS Medical Max Strength is a widely-available, often-seen appetite suppressant. It’s there, on the supermarket shelf.

The ingredients are hidden under the proprietary blend moniker – basically, we don’t know what’s in it, it could contain anything. This could prove dangerous if you have an allergy or sensitivity to some of the unknown ingredients.

Cost-wise, it’s expensive, with a month’s supply coming in at around £90. If you really must buy it, look for a discount outlet. Or, save even more by not buying it at all – there are much better products available.

Customer feedback is average to poor. We could criticise this all day long, but, we’ve got better things to do. Ye have been warned.

Our main problems with XLS have never gone away. It’s all just clever marketing and questionable products, and expensive in the long run.


Fat burners are the most popular weight loss product on the market. They are widely and safely used by lots of people.

They are mainly used for weight loss but can also be useful for improving athletic performance. Stimulant-based products can increase alertness and provide extra energy.

Their promises of easy weight loss should be taken with a pinch of salt, however. Nothing happens by magic.

For best results, you should combine using a fat burner with an improved diet and some exercise.

Finding a good quality fat burner is important – we suggest using one that’s geared towards boosting metabolism and thermogenesis. A faster metabolism is effective for weight loss.

Not everybody will find a fat burner useful. For those that do, a fat burner can provide the boost they need.

By increasing metabolism, a fat burner can make losing weight much easier than by just going it alone.

  1. I have osteoarthritis and fibromyalgia and going through menopause and have put 4 stone on and I hate carrying the extra weight, I do try to exercise a bit every day but I need help. So many pills and other stuff I could and have tried, even been ripped off so I’m very careful now. Advice would be so good and appreciated. Ty

  2. I tried Phentaslim because of this website. Did alright with it, if I’m honest. I lost a decent bit of weight, didn’t really put in the effort though. If I was twenty years younger i think things would be much different!

  3. I’ve had reasonable success using a fat burner for my weight loss. I like this article because it tells the truth.

    I used pills and changed the foods I was eating and starting doing proper exercises, such as jogging and weights. My weight loss has been steady and hasn’t crept back on. I’m very realistic about how to achieve my weight loss goals.

    Using a pill I felt I could push myself harder. I had more energy and felt motivated to persist. Some times it was hard. When it was freezing cold in winter all I wanted to do was stay inside and hide, eat comfort food. But, no, I persisted. I discovered lots of new recipes and wow, healthy comfort food does exist. All you have to do is research. The internet makes this all so easy.

    People have to understand that products are made to be used in certain ways. I find it saddening so many people think they can just buy a pill and expect a miracle. Take a pill but continue stuffing their faces. They then complain that they’re still fat, having made no effort. Next, they go and buy something ridiculous from shopping TV channels, like vibration plates, etc., in their unrealistic pursuit of weight loss without effort. As they say, a fool and their money are easily parted.

    If you genuinely want to lose weight and plan to use a diet pill, just make sure you plan to use it properly. Listen to all the extra help and make the changes you need to for weight loss to happen.

    1. I agree. Some people are sooo frustrating. Couple of women I work with are typical of who you refer to.

      Some people just don’t want to take responsibility for their own weight issues. Just prefer to blame someone else for their own shortcomings.

      Fat people blame the food manufacturers for their weight. Too much sugar. Too much salt. Too convenient.

      As far as I’m aware, drinking coke, eating crisps, and cooking pizza daily are not mandatory. Don’t blame the manufacturers, blame your own hand as it soars towards your gaping mouth.

      Try buying a cucumber or a lettuce or a carrot instead of pre-made frozen junk. Wah, wah, wah, I’m fat and getting fatter. Boo hoo. Get a grip. Stop kidding yourself. Change your habits. Or, shut up and just be fat.

      Rant over 🙂
