NRG Thermofuel Review

The manufacturers of this product believe that by using the pills, individuals will be able to help themselves lose weight by changing the way that they exercise to a more efficient and fuller regime. This is as well as any effects that may result from the pills alone making weight loss even easier to achieve.

What is seemingly different about this product is that it contains an impressive 16 active ingredients which is said to be what makes the pills so powerful and as well as this it is also claimed to be great tasting so shouldn’t be hard for users to tolerate.

So how exactly can the NRG Thermofuel diet pills help you to achieve your weight loss goals?

Claimed weight loss benefits

In terms of our 5 main weight loss properties, the manufacturers of the NRG Thermofuel diet pills actually make quite an impressive claim. They state that their product acts as both a metabolism booster and an appetite suppressant and also suggests that users follow a diet plan and exercise regime in combination with taking the pills.

It is undoubtedly the case that this product contains a huge amount of stimulants, some of which are known to be proven thermogenic agents, so our experts would agree with the first claim in relation to enhancing the metabolism although. This is not to say that they are as powerful allegedly claimed since some of the ‘thermogenic’ ingredients are not sufficiently researched.

In terms of the pills being able to suppress the appetite, there is very little evidence that this is the case. The main ingredients responsible for reducing the appetite are either unproven or would not have enough of an effect to make a real difference.

Lastly, one good thing about this product is that it does recognise that the pills will not work to promote weight loss on their own and plenty of support in terms of fitness advice is available on the website.

Below we examine how the nature of this product works in general and find out more concerning how it can affect the ability of users to lose their excess weight.

How NRG Thernofuel Works

The manufacturers of NRG Thermofuel imply that their product works in 3 different but interconnected ways. The first way in which it helps users to burn fat is by including a large amount of thermogenic ingredients believed to increase the metabolic rate so that users can burn more fat.

In addition to this, the pills are also claimed to be able to keep hunger pangs at bay through certain appetite suppressing ingredients like Citrus aurantium and L-tyrosine. This means that as well as burning more fat users will also be consuming less calories.

Lastly, to keep users motivated and to help maintain a good overall wellbeing the pills contain a variety of B vitamins which is particularly useful in this case because it is emphasised that a low calorie diet and exercise regime are needed for the pills to work so the more motivated a user is the more exercise they will feel able to do.

Due to the effects that the pills may have on the body we would not recommend their use for the following groups of people:
– Pregnant or nursing women.
– Those who may be allergic to any of the ingredients, binders or fillers used in the product.
– Those who have a family history of or are suffering from any digestive conditions.
– Those who have a family history or are suffering from or have previously suffered any type of heart condition or defect.
– Those who are particularly sensitive to caffeine and stimulant based products.
– Those who have a family history of or are suffering from diabetes or any other blood sugar related problems.
– Those who have a family history or are suffering from Irritable Bowel Syndrome or any other gastric disorder.
– Those who are currently taking insulin.
– Anyone under the age of 18
– Those who have any other underlying medical issue.

Key NRG Thermofuel Ingredients

The NRG Thermofuel pills are marketed as being the ‘most potent’ available on the market due to the manufacturers only using the ‘absolute best’ ingredients. So what are they? Well, these pills contain a huge 16 ingredients including a number of B Vitamins which are said to help keep users motivated and energised.

You can find a full ingredients list for the pills on the main website and most of them are both stimulants and thermogenic agents, which are claimed to help boost the metabolism of users while some are also believed to suppress the appetite.

The main ones in terms of content though are guarana extract, L-tyrosine and Citrus aurantium. The first of these contains a substance called theobromine, which is similar in structure to caffeine. This means that the guarana extract can work as a thermogenic agent speeding up the rate at which fat is burnt within the body via the production of heat. It is also believed to increase energy and mental alertness in users due to the fact that it is a stimulant. In addition, some claim that it can also help to suppress the appetite.

L-Tyrosine is also believed to affect the appetite of users by helping to make neurotransmitters such as dopamine, epinephrine and norepinephrine which control our urge to eat.

Lastly, the Citrus aurantium is another ingredient that is thought to help control the appetite because it contains a compound called synephrine, which is used as an alternative to ephedra. It is said to have stimulant like effects including the ability to boost metabolism while having none of the negative effects associated with its predecessor.

Weight Loss Power: 40/100

Despite the fact that these pills contain so many different ingredients we have scored them quite low in this area. This is due to the fact that in terms of appetite suppression there was very little evidence that proved the manufacturers claims and in addition to this, the claims concerning metabolism enhancement are unlikely to be as impressive since some of the thermogenic agents did not have any scientific proof behind them. Having said this there are some proven ingredients included in the pills so combined with diet and exercise there is still a chance that users might see some weight loss results – how much of this can be attributed to the actual pills though is questionable.
Speed of results: 50/100

There is very little information given about how long the pills will take to work aside from generalised statements. Given that they are to be combined with diet and exercise though may mean that users will see results quite quickly, although this will obviously depend on the quality of their diet and intensity of their exercise regime.
Appetite Suppression: 10/100

We have scored the NRG Thermofuel pills very low in this area because although they do contain some ingredients which are believed to help reduce the appetite, the actual clinical research did not give any conclusive proof that this would be the case especially in the quantities used in the pills. Having said this, stimulants themselves are known to have some appetite suppressing properties and there are a huge amount of them in the pills so users may experience some effect although this is likely to be minimal.
Long Term Results: 65/100

What is quite good about this product is that it does encourage users to make healthier lifestyle changes by emphasising that for any weight loss to occur the pills must be used with diet and exercise. Even though this is a lot more than most other diet product manufacturers there is no set routine given to users that they must follow. Instead though there is plenty of advice available in terms of fitness and exercise on the website but the fact remains that most of the long term outcomes will depend on the willpower of the individual. Unlike other diet products though, when users stop using these pills they are less likely to put any weight that they have lost back on since they are more likely to continue with their new diet and exercise habits.
Safety: 30/100

Worryingly the pills have scored low in this area. This is due to two different reasons; the first is that the pills contain a huge amount of stimulant ingredients renowned for causing unpleasant effects including nausea, insomnia and headaches. Of a more serious nature though is the fact that there have been warnings about some of the ingredients used in the pills, specifically the Citrus aurantium which has been linked to very serious symptoms such as heart attacks and strokes.
Value for money: 40/100

The price of these pills is very reasonable at £24.99 per month at its lowest, this does not however mean that the pills are good value for money. Given the associated health risks and the lack of scientific evidence for some of the ingredients used in the pills our experts have scored them quite low in this area. We do not believe that even at this price that it is worth the risk experiencing such serious side effects, especially when there is no solid evidence to suggest that the pills will cause any significant weight loss in addition to that which would otherwise be achieved through diet and exercise alone.

NRG Thermofuel Side Effects

The NRG Thermofuel diet pills contain a huge amount of stimulant ingredients in fairly large quantities. Although not mentioned on the website this mixture of powerful compounds is likely to produce many of the symptoms associated with a high intake of caffeine. This will most likely include cramping, nausea, insomnia, anxiety and even high blood pressure.

As well as this, some of the ingredients contained in the pills are quite under researched in this area and there have been warnings particularly about the ingestion of Citrus aurantium, an ingredient containing synephrine, which is found in fairly high quantities in this product. These concerns include risks of serious heart problems including both heart attacks and strokes.

Overall Verdict

Despite making impressive promises, our experts are of the opinion that the NRG Thermofuel pills are unlikely to help users in their weight loss goals. This is for a number of reasons, the first of which being that some of the ingredients used in the pills are not actually clinically proven to have any effect on weight loss.

As well as this, there are very serious warnings against the use of some of the ingredients in the pills due to the gravity of the side effects that they may cause and the high stimulant content of the pills only causes more concern and a higher likelihood of experiencing adverse effects.

Furthermore, although it is a good thing that the manufacturers behind the pills encourage diet and exercise this leaves our experts dubious as to how much of users’ weight loss (if there has been any) can actually be attributed to the use of the product as opposed to their own effort.
