Raspberry Ketones And Exogenous Ketones

Raspberries, Red, Fruit, Berry, Ripe

Tablets and concoctions that guarantee simple weight decrease never appear to become unfashionable.

Navigate the web and you’ll discover raspberry ketones credited as a herbal enhancer to assist with weight reduction. Before deciding to purchase raspberry ketone capsules, powders, or any other type of supplement, the following should be taken into consideration.

Ketone Hype

Aroma-producing elements located in red fruits and berries are known as raspberry ketones.

Ginger Hultin, a certified nutritionist and official representative of the Academy of Nutrition and Dietetics, states that compounds which lead to the sweet aroma of mangos can be found in other fruits, such as kiwis, peaches and apples, as well as some vegetables like rhubarb.

Raspberry ketones are usually employed as flavorings for food and beverages.

What is the connection between the fragrance of raspberries and shedding pounds? Studies conducted on mice and rats in a laboratory environment indicate that, when fed in massive amounts, raspberry ketones can stop these creatures from gaining weight.

It’s a colossal leap to allege that taking raspberry ketones will augment one’s fat metabolism and result in weight loss. Results from animal studies often do not carry over to humans.

“Right now, there is no reliable scientific evidence that raspberry ketone improves weight loss when taken by people,” Hultin says. “Importantly, there is insufficient reliable information available about the safety of raspberry ketone.”

Kristin Kirkpatrick, a dietitian employed by Cleveland Clinic’s Wellness Institute, does not propose raspberry ketones as part of a diet: “Even though it is thought of as a fat-burning item, there is very little sound proof that it actually works.” To conclude, she states, “No research has been done with humans, and the hope and expectation doesn’t match the available data.” I would rather recommend that my patients consume real raspberries, which are a natural food.

Kirkpatrick emphasizes that following a diet based on whole foods could be the deciding factor for successful weight loss, referring to new research published by the Journal of the American Medical Association.

Ketone Confusion

It’s simple to mix up numerous fashionable yet distinct ideas associated with ketones and losing weight. Raspberry ketones are just one type of ketone supplement.

Supplement formulations containing “exogenous” ketones are accessible. As well, the keto diet, which is seen as contentious, is becoming more widespread Here’s a quick breakdown of terms:


The body engages in ketosis when it breaks down stored fat and uses it as fuel. That results in byproducts known as “endogenous” ketones.

Exogenous ketones

Ketones that do not originate within the body are known as “exogenous” ketones. Certain types of weight loss supplements include compounds called exogenous ketones, including both naturally occurring ketone salts and synthetically created ketone esters.

A preliminary study with 20 participants revealed that consuming drinks that contain ketone esters had a positive impact on blood sugar levels.

Maleah Holland, an assistant professor at Augusta University in Georgia, states that ketones can be a useful fuel source for keeping blood glucose levels steady and keeping away feelings of cravings, which might result in shedding pounds.

Holland is researching the consequences of a ketogenic diet and ketone supplementation through the use of ketone salts.

The outcomes of the blood tests on young, healthy adults demonstrate that the ketone salt Holland has been examining is secure. She mentions that the impact of ketones on weight loss varies from one person to the next.

Figuring out the exact way potential weight loss may occur, like reduced hunger or improved metabolism, necessitates more exploration, she adds.

Ketones originating from an external source, such as a dietary supplement, are known as exogenous ketones. Exogenous ketones can be used to help the body enter into a state of ketosis. They can also help with the following situations:

Lessen the Effects of a Carb Crash

If you consume a meal that is high in carbohydrates, it can be beneficial to take exogenous ketones to reduce the likelihood of experiencing a sudden drop in energy due to a sugar crash.

This supplement provides an injection of ketones to give you more strength and clear thinking. This can be useful when you have consumed too many carbohydrates. And they work quickly. Many folks will experience the effects of external ketones within a few hours or even faster.

Getting Into Ketosis for the First Time

Beginners of the ketogenic diet may go through a period often referred to as the “keto flu”.

These are negative consequences that may include feeling sick to your stomach, difficulty focusing, throbbing in your head, and other signs similar to those of the flu. Taking ketones as an additive can often reduce the severity of these signs and symptoms.

Performing Athletically on Ketosis

Some athletes struggle to completely remove carbs from their diets due to intense physical workouts. Consequently, athletes may take extra ketones to take advantage of the psychological and physical advantages offered from being in ketosis, while still eating a larger portion of carbohydrates each day.

Exogenous ketones do not aid in slimming down, they merely enable you to have the fundamental energy to eliminate more fat.

Different Forms of Exogenous Ketones

The following are some of the most frequently used exogenous ketones, which are far more advantageous than raspberry ketones as we’ll discover later on.

Ketone Esters

This is an unbound form of the ketone BHB. Generally, it is possible for the body to make use of ketone esters rapidly, which can help increase levels of ketones in the bloodstream. Gastric distress can be a side effect.

Ketone Salts

A ketone body is usually connected to one of the four elements sodium, calcium, magnesium, or potassium. Although it may not be as proficient in increasing ketone levels, it is much more tolerable for your digestion.

MCT Oil 

Your body can take advantage of MCT oil, along with other medium to shorter chain fatty acids, to help increase ketones. Your cells break down MCTs, indirectly creating ketone bodies.

Ketogenic diet

The idea behind the keto diet is that by reducing carb intake while significantly increasing the amount of fat consumed, your body can enter a state of ketosis. Consequently, it oxidizes both the fat you consume through your diet and existing fat reserves in your body, converting them into ketones and leading to a decrease in your body weight.

However, the keto diet is difficult to follow. Nutrition specialists have voiced disapprobation over the unsustainable nature of the diet, pointing out its excess fat composition is not favorable for health.

Raspberry ketones

Holland has argued that the phrase “raspberry ketones” is an inaccurate name. She states that these substances are not ketone bodies, and thus will not increase the amount of ketones in the body. Exogenous ketones are similar to ketones that are produced naturally in a human’s body and can boost the amount of ketones in the body.

Holland comments that many people assume that raspberry ketones are the same as ketones that come from an exogenous source or a ketogenic diet, even though the data supporting this is positive.

Evidence to Date

A research conducted in 2010 demonstrated that providing laboratory rats with a large dose of raspberry ketones provoked the secretion of adiponectin, which is a hormone responsible for regulating fat metabolism.

A 2005 study of rodents consuming a high-fat diet discovered that the mice given raspberry ketones experienced improved fat metabolization and decreased weight gain.

In 2016, the National Raspberry Council sponsored an analysis that was printed in the Journal of Berry Research. The results showed that mice put on a high-fat diet and given products from raspberries, including ketones, appeared to have put on less weight than the mice that were not provided with raspberries.

So far, a single randomized and controlled experiment has been conducted to study the consequences of a dietary supplement composed of raspberry ketones in relation to weight loss, which was confirmed by the Office of Dietary Supplements located in the National Institutes of Health.

In April 2013, a study was published in the Journal of the International Society of Sports Nutrition which included a group of 70 obese people who were given either a multi-ingredient product designed to result in weight loss (with raspberry ketones being one of the ingredients) or a placebo.

Everybody taking part in the activity kept to a diet which had little calories and did moderate exercise.

At the termination of the 8 week experiment, participants taking the supplement had a mean weight reduction of close to 4.2 pounds, compared to just below 1 pound of weight loss for those in the control group. However, the results are considered inconclusive.

Due to the insufficient amount of test subjects (45) and the inclusion of other components in the supplement, it is not possible to discern the effects of solely raspberry ketone, as noted by the National Institute of Health website.

Safety is another unknown. Diets usually consist of only a miniscule amount of raspberry ketones on a regular basis, as indicated by the surveillance of the National Institutes of Health.

In comparison, dietary supplements offer amounts of raspberry ketones ranging from 100mg to as much as 1,400mg. No human study has been conducted to assess the safety of the doses referred to.

Beta-hydroxybutyrate (BHB) Is the Most Efficient Ketone

This has been previously mentioned, but BHB (3-hydroxybutyric acid or 3-hydroxybutanoic acid) is one of the three ketones that your body produces. The most frequent type of ketone in one’s bloodstream is 78% of the total.

Your body employs both endogenous and exogenous varieties of BHB. BHB is the type of compound that the body produces internally. Taking exogenous BHB in a supplemental form, such as salts or esters, is common.

BHB that is created from within the body is derived from acetoacetate (AcAc) and is the primary type of ketone utilized to generate energy. BHB is reliable and most plentiful in your body. But you can lose acetone through sweat and exercise.

There are two types of BHB: D-BHB, which is produced in large volumes and used by cells as an energy source; and L-BHB, created in more limited amounts to aid in the manufacturing of fatty acids.

Your body has the capability to employ any of the three ketones for energy, yet BHB is the most productive. BHB has been shown to assist in the following:

  • Reduce inflammation
  • Slow tumor progression and help fight cancer
  • Improve insulin sensitivity
  • Boost metabolic functions and heart health
  • Increase athletic performance
  • Enhance cognitive function and memory
  • Increase your lifespan

It’s also a more efficient energy source than glucose. The physical and mental benefits of BHB are undeniable.

You need to eat a very low-carbohydrate, high-fat diet to get more BHB in your blood. Try occasional fasting and taking exogenous ketone and MCT oil supplements too. Your body naturally produces its own BHB, but taking in extra exogenous ketones can help to elevate your ketone levels quickly.

Scientific Research on Raspberry Ketones

The principal problem with scientific studies pertaining to raspberry ketones and human weight loss is that they simply do not exist.

No studies on humans have been done demonstrating any advantage of utilizing raspberry ketones.

People attempting to persuade customers to buy their purported weight loss supplements often refer to some studies that used rats or mice to bolster their reliability, but the results of these studies are not as noteworthy as they might lead one to think. Here are some examples:

  • In one study, fat cells were isolated from rats and grown by researchers in a test tube with raspberry ketones added. This made the cells release more adiponectin and increased fat breakdown, but this doesn’t demonstrate that the same could happen in a living human or even a living rat.
  • In another study, researchers gave 40 rats a fattening diet along with raspberry ketones. Their adiponectin levels increased, but they were given the raspberry ketones in abnormally high amounts — over 100 times a feasible (or likely safe) amount for a human to take at all, much less on a regular basis.

You can decrease fat and boost adiponectin within your body in a more healthy manner, such as through a low-carb regime, exercising on a regular basis and drinking caffeine-based beverages such as green tea or coffee.

Raspberry Ketones Have Nothing to Do With Promoting Ketone Levels

To know more about the different kinds of ketone supplements obtainable in the market, please consult the Perfect Keto guide to ketone supplementation. Take extra care when considering any phony ketone supplements that won’t help you along your ketogenic journey.

Most Raspberry Ketone Products Aren’t Legitimate Ketone Supplements

Many raspberry ketone products are created using synthetic flavoring agents. It’s much more difficult to find real raspberry ketones. A good majority of the nutritional supplements available are composed of anise seeds that have been ground and combined with a slight amount of raspberry ketone.

Due to the high price of components, many labels include fillers and synthetic elements to make the supplements more affordable.

Long-Term Effects of These Ketones Is Unclear

It is not possible to guarantee that raspberry ketones will be effective, unlike exogenous ketones such as BHB, which can be tested to show a rise in ketone levels.

The U.S. The Food and Drug Administration acknowledged the food additive as being “Generally Recognized as Safe”. That took place during the 1960s, prior to when they were viewed as a product to assist in burning fat.


Raspberry ketones are not related to putting someone in ketosis or losing fat mass, despite what it may appear. It’s easy to be drawn in by the attractiveness of the product, however these ketones are unlike any your body produces.

Even if you only wanted to use raspberry ketones for weight loss and weren’t trying to copy ketosis, you would find nothing but an emptier wallet and disappointing results.

If you want to get into ketosis quickly, exogenous ketones can help you out. But do your research.

Exogenous ketones can help people maintain their energy levels and shed extra pounds, but they should not be considered a weight loss pill. Ketones from outside sources are available as ketone salts, ketone esters, and oils like MCTs.

The most beneficial exogenous ketones are those that increase the levels of BHB in the body. BHB is the primary ketone body present in a person’s body and is more effective in providing energy than glucose.

It would be best not to spend your time or resources on raspberry ketones. Focus your energy on following a nutritious, ketogenic eating plan for actual outcomes.
