Do Raspberry Ketones Really Work? A Detailed Review

Gaining weight is easy, just eat out at your favorite fast food joint three times a day for a few weeks, and you can be well on your way to obesity and a gastric bypass. Losing fat, on the other hand, can be as challenging and painful as trying to squeeze water from a stone.

Did you know that in America, a third of the population is overweight with the next third is obese with only around 30% of the population being in the healthy weight range? This increasing number of men and women who are overweight and obese want to lose the excess fat and lead a healthier life but kicking the fat gain habits is difficult. And as for the conventional diets and weight loss methods, these are proving to be quite unsuccessful as over 85% of people end up failing in their weight loss.


The difficulty of achieving successful weight loss using conventional fat burning methods is the main reason weight loss has been a big industry for quite some time now. This industry now provides America and the rest of the world with a new miracle weight loss product or ingredient being periodically introduced that convinces the public on exactly what they need to buy to help lose weight.

Many weight loss products are available in the market which claims to boost weight loss and give results in just a few weeks including shakes, pills, and herbs with one of the most popular being Raspberry Ketones. Today, we are giving you a detailed look at Raspberry Ketones for weight loss, its attributes, its benefits, and its evidence for fat burn.

What Raspberry Ketones promises is the ability to help your body burn fat faster by causing the fat in the cells to be more effectively broken down. Raspberry Ketones is also said to increase the levels of hormone adiponectin which helps in metabolism regulation and suppresses appetite.

What Are Raspberry Ketones?

Raspberry Ketones are the natural component that gives raspberries their aroma and taste. This element is also found in blackberries, kiwis, and cranberries. It’s also popular due to its use as a flavorant in ice cream, soft drinks, and other foods as well as its use in cosmetics.

The natural component of Raspberry Ketones from extracting raspberries is costly with the cost being around $20,000 for a kilogram of natural Raspberry Ketones. The reason for the extreme price tag is the low percentage (0.0001-0.0004%) of the fruit contains Raspberry Ketones that is useful in weight loss which is why diet pills and cosmetics that can only use synthetically produced  Raspberry Ketones which is just as effective at weight loss.

How Does Raspberry Ketones Work?

The molecular structure of Raspberry Ketones is similar to the molecular structure of Capsaicin found in chili peppers and synephrine which is a stimulant, both of which boost metabolism. In the initial stages of the research into Raspberry Ketones, this similarity was the reason for speculation of the effectiveness of the compound on metabolism and weight loss.

When tested on isolated fat cells from rats cultured in a test tube, Raspberry Ketones caused two effects:

  • The component caused the cells to become more sensitive to the effects of norepinephrine, a hormone responsible for fat burning.
  • The component also resulted in the release of the hormone adiponectin from the fat cells.

The hormone, Adiponectin that is released by the fat cells is responsible for effectively affecting the metabolism and the levels of blood sugar. This hormone is associated with metabolism due to there being higher levels being found in thin people while overweight people had lower levels of Adiponectin.

More evidence of Adiponectin comes in the fact that studies have shown that those with lower adiponectin levels are more at risk of having type 2 diabetes, heart disease, fatty liver, and obesity. The relation between adiponectin and being obese has convinced many that if they increase the levels of hormones in the body, they will experience a reduction in weight gain and increase in fat burn and metabolism.

Fortunately, you can increase your levels of Adiponectin by around 260% in as little as a week by simply working out and exercising. Coffee has also shown to be effective at increasing Adiponectin levels in humans. However, Raspberry Ketones is considered the easiest and most effective method of increasing Adiponectin.

Scientific Evidence of Raspberry Ketones Aiding Fat Loss:

There are some studies which were conducted on Raspberry Ketones to help understand how the compound works to promote fat burn.

A study in 2005 analyzed the ability of Raspberry Ketones in countering obesity by feeding some rats a fattening and unhealthy diet. Some of these rats then got to eat some Raspberry Ketones while others didn’t. The results showed that the group of rats that were fed Raspberry Ketones weighed 50 grams while the group that wasn’t fed the compound weight 55 grams which is a difference of 10%.

A second study was conducted in 2012 which used 40 rats that were similarly fed an unhealthy and fattening diet. Also similar to the previous test, Raspberry Ketones was given to some of the rats which showed increased levels of Adiponectin as well as showing signs of protection against fatty liver. This test showed that Raspberry Ketones could increase Adiponectin responsible for efficient metabolism and weight loss. However, it should be noted that the amount of Raspberry Ketones given to the rats in this test was higher than the previous test conducted.

Another study which uses Raspberry Ketones along with other components like garlic, ginger, and caffeine was conducted in 2013 on 45 human participants over an eight-week study. In this study, the participants took the multi-ingredient supplement on a daily basis with a calorie controlled diet and exercise training to help promote weight loss. The results of this study were satisfied with a 7.8% fat loss for those who took the supplement with Raspberry Ketones in it while a 2.8% fat loss for those who received the placebo.

Should You Get Raspberry Ketones For Weight Loss?

Well, the advantages of Raspberry Ketones for weight loss can be seen by taking a look at the scientifically proven data from the studies. However, Raspberry Ketones which is used in supplements and is commercially available is synthetically produced which might not be what you are looking for.

But if you are someone who is struggling for a solution to your weight gain problem, even after trying multiple weight loss methods and diets, Raspberry Ketones supplements might be your best choice yet. For those who want to work hard and exercise, Raspberry Ketones can also be for you because this will help speed up your fat burn and fat loss so that you can get fit and trim in no time at all.
