How Raspberry Ketone Plus Works

woman wondering how diet pill works 538

Raspberry Ketone Plus is primarily claims to be a fat burning diet pill which supposed encourages the body to burn fat faster and target more fat too. It also purportedly boosts your metabolism which could help to convert fat into energy quicker. Raspberry Ketones are found in raspberries and are responsible for the smell of the fruit. Recently it has been suggested that these compounds have potent fat burning capabilities.

The other ingredients are a fairly common blend of caffeine and green tea which are purportedly used to raise your metabolic temperature and therefore burn more calories.

Raspberry Ketone

Raspberry ketones are thought to work by increasing the activity of a hormone called adiponectin, the function of this hormone is understood to be exclusively to burn fat cells. It has been said that obese people have a lower level of adiponectin in comparison to leaner people. It has been suggested that obese people have a high level of insulin which inhibits the production of adiponectin which tricks the person into thinking they are still hungry and leads to a lower metabolic rate. Therefore, a way of decreasing the levels of insulin may be needed in order for the adiponectin to be effective.

This is where the raspberry ketones come into the picture. The ketones found in raspberries supposedly play a part in inhibiting the production of insulin resulting in two benefits; the first potential benefit is that the individual may feel as though they are full and generally eat less during the day, the second potential benefit is that adiponectin levels could, in theory, be increased due to the low levels of insulin and thus fat stores may be used as the prime energy supplier rather than carbohydrate or muscle glycogen.

The effect described above could be useful as the body has a natural predisposition to store fat and use carbohydrates instead as fat is said to be harder to break down and provide energy at a slower rate compared to carbohydrate or sugars. There is some caution that needs to be taken when dealing with changing levels of insulin however; this is because insulin controls the level of blood sugar and constantly low levels of blood sugar can lead to health problems.

Bowl Of Raspberries (538)

The key ingredient is Raspberry Ketones which is thought to boost fat burning. All of the ingredients are said to be natural (although raspberry ketones may be made synthetically in a laboratory) and can be taken by vegetarians. Other ingredients include African Mango, Green Tea and Acai Berry. All of the ingredients have been suggested to help weight loss and some may come with other benefits too.

The product does include a small amount of caffeine which may make you feel more energetic but may also leave a minority of people struggling to sleep, especially those who are sensitive to caffeine.

Clinical Studies

Clinical Researcher 538

The ingredient list includes raspberry ketones, African mango, green tea, caffeine and acai berry, amongst others. As no clinical studies have been performed on the product as a whole, we will examine if studies in to these ingredients support the supposed weight loss potential of Raspberry Ketone Plus.

Raspberry Ketones

A study conducted by Morimoto et al (2005) investigated the weight loss potential of raspberry ketones in mice. In order to test the effect of raspberry ketones the mice were subject to two stages of experimentation; the first stage involved the mice being fed a high fat diet for a period of ten weeks with a 2% raspberry ketone content; stage two involved the mice being fed a high fat diet for six weeks with no raspberry ketone content followed by a five week high fat diet with a 1% raspberry ketone content.

The study discovered that when the raspberry ketones were introduced into the diet the mice lost both body weight and internal body fat percentage. The greatest difference was observed when raspberry ketones accounted for 2% of calorific intake. These outcomes were attributed to the ability of raspberry ketones to alter the metabolism of the body so that it would burn a higher percentage of fat tissue as opposed to carbohydrates or glycogen. The two concerns about this study are that this effect was seen in mice and so its translation into humans cannot be truly estimated, additionally the dosage of raspberry ketones was not specified and even if it was would not be relevant in terms of correct human consumption.

Acai Berry

A study conducted by Udani et al (2011) sought to investigate the effects of Acai Berry consumption in a population of 10 obese participants. The participants were instructed to continue with their everyday routines for a 30 day period while eating 100g of acai berries on a twice daily basis. The study measured the levels of glucose, insulin, cholesterol and triglycerides.

The study discovered that the consumption of acai berries led to reductions in both glucose and insulin levels. This combination meant that on average the participants used more fat as an energy source; this is because low insulin levels encourage the burning of fat. A common reason for obesity in humans is that insulin levels are high due to poor diet and lack of exercise. Additionally, the consumption of acai berries reduced the amount of LDL cholesterol (the bad kind). However, there were no changes in blood pressure. This experiment illustrates that the weight loss potential of acai berries are slim and have not been conclusively proven.

Green Tea Study

A study carried out by Viechtbauer and Westerterp (2009) identified eleven studies in which Green Tea had been used as an enabler of weight loss. The study discovered that a common pattern was that metabolic rate and thermogenesis were increased in regular drinkers of Green Tea compared to regular drinkers of coffee. The authors also remarked on how racial origins seemed to determine the effectiveness of Green Tea as a weight loss option.

They discovered that in studies of Asian origin, Green Tea proved to have a unanimously successful outcome when it came to weight loss. However, studies carried out in the Western World were unable to replicate this with similar numbers of studies reporting Green Tea was either successful or unsuccessful.

Raspberry Ketone Plus Side Effects

Woman With Stomach Ache 538

Raspberry Ketone Plus is full of natural ingredients, but unfortunately this does not mean that it won’t have any side effects. Consumers may experience a bad reaction to the extra caffeine that is included in this supplement but it may only affect people who are particularly sensitive to caffeine.

Raspberry Ketones

Although generally thought to be safe for consumption in the short-term, the long-term safety of raspberry ketones may be a concern. It has been noted that raspberry ketones are chemically similar in composition to synephrine – a chemical that has been associated with severe adverse effects, including heart attacks and strokes. Unfortunately an overall lack of information on raspberry ketones means that we cannot be sure what the side effects may be.

Green Tea

Green tea is generally believed to be safe for consumption, although there have been associations with liver problems if it is taken in large quantities for large periods of time. Green tea also contains caffeine, which may cause side effects such as anxiety, headaches, jitteriness, nausea, insomnia, increased heart rate, and increased blood pressure, amongst others.

How to Use

Woman With Pills 538

The official website doesn’t really offer much in terms of guidance for how to use the product; it simply states that you should take one tablet at breakfast and one tablet at lunch. Thankfully the website goes into more detail about people who should avoid taking the product and what precautions to take if using the product. The manufacturers state that in no circumstance should you exceed the dosage described above.

If you forget to take a tablet there should not be any danger in taking one at dinner for example, but you should never take more than two tablets per day. There then follows the generic warnings to keep the product away from children and not to use the product if the seal has been damaged.

The product should also be stored in a cool and dry place and out of direct sunlight. There is no information supplied by the website regarding to if pregnant women or those on current prescribed medication can use the product so it is suggested that you consult your doctor before purchasing.

The company claim that the testimonials made by customers are all 100% genuine although it doesn’t show any negative comments and the 5 star ratings differ significantly from the average 3 star ratings on Amazon. There does not seem to be any complaints regarding the company itself. Rather, the negative reviews seem to be about the ineffectiveness of the product itself although there are some favourable reviews.

Where to Buy Raspberry Ketone Plus


Firstly let us look at the options that the manufacturer, Evolution Slimming, offers. The website appears to be offering special deals across the majority of their products. A one month supply of Raspberry Ketone Plus (60 tablets) is currently retailing for £19.95, this seems to be a special offer at the time of writing as the figure £39.95 is crossed out.

The second option being advertised on their website is a two month supply of Raspberry Ketone Plus (120 tablets) for a price of £36.95, once again this price appears to be a special offer based upon the full price of £79.99. The third option is to buy a three month supply of Raspberry Ketone Plus (180 tablets) for a total price of £53.95, this is reduced from the full price of £119.85.

The final option is to buy 360 tablets of Raspberry Ketone Plus for a price of £94.95; this is supposedly reduced from the full price of £239.70. It is unknown if the full prices that are advertised are entirely representative of the normal retail price, they could have increased the full price slightly before putting on the special offers to make the offers look more substantial. The website also offers combination deals where they offer Raspberry Ketone Plus along with either one or two other products.

On Amazon, the product is retailing for £18.95 for a one month supply and is available with free delivery; this means the product is £1 cheaper than on the official website. Raspberry Ketone Plus is also available on eBay for the same price as is advertised on the Evolution Slimming website, although we do not recommend purchasing supplements from eBay.

Overall Verdict

Raspberry Ketone Plus features some popular diet pill ingredients as well as some ingredients which have been the subject of some clinical testing. However, none of the ingredients have been conclusively proven to aid weight loss and the key ingredient, raspberry ketones, has only been subject to preliminary studies. The official website does not run a free-trial scam, but some information is lacking from the official website, including ingredient quantities and manufacturing standards.
