Raspberry Ketones Review - Does This Natural Extract Work?

By Summer Banks on Oct 27, 2016
Raspberry Ketones Review

The results of my research into raspberry ketones were somewhat surprising. We took a closer look at the side effects, ingredients and clinical studies. Additionally, we sorted through hundreds of user responses and comments from around the web. At this point, we condensed and summarized to give you the info you need.

EDITOR'S TIP:

What are Raspberry Ketones?

To start with, raspberry ketones are derived from red raspberries. This is a chemical that is sometimes used to manufacture fragrances, foods and cosmetics. It has a potent flavor and aroma. Furthermore, this substance is used in a number of over-the-counter weight-loss supplements. This ingredient may help elevate adiponectin (a hormone) levels, which in turn aids with fat reduction. It is also a natural component that provides some antioxidants. This ingredient is often combined with other natural herbs as well.

We are not sure when the first raspberry ketones weight-loss supplements were released. However, this ingredient gained a lot of popularity after being discussed on television programs in 2012. As a product, you can purchase it at local retailers and through online stores. We like that it’s natural and that we found some positive customer comments, but read on…

Fad Ingredient – “Concerned?”

One concern we have is with raspberry ketones ingredients. “There is no solid clinical evidence that supports this fruit extract as an effective weight-loss aid,” said our Research Editor. “WebMD even states that this substance has not been proven to help treat obesity.”

One user stated, “These did absolutely nothing for me. No change in how I felt. No extra energy. Nothing.”

Then again, a different customer said, “Hoping for some weight-loss. Been taking this for a few days and eating well, but I don’t feel a difference yet. No raspberry ketones side effects either.”

Another posted, “These are fairly easy to take. Not sure if they are working though.”

Minimal Results – “Losing Weight with Raspberry Ketones?”

According to raspberry ketone reviews, dieters aren’t exactly noticing results. One person revealed, “Waste of money. I did not notice a difference in my appetite or weight.”

“Still not sure about this one. Been taking a month and have dropped a pound,” commented another.

However, a different customer said, “Didn’t work much for me, but my wife said she liked it.”

“I have noticed some results from these raspberry ketones pills,” posted another.

The research we’ve done has shown if there’s a specific part of a diet product that’s concerning, like being ineffective, the chances of long-term success are limited. If raspberry ketones fail to produce real results, this could be a dilemma.

The Science – “Solid?”

Although some research has been conducted with raspberry ketones, it is inconclusive at this point. There are no clinical studies that truly support this ingredient as an effective weight-loss aid. We at DietSpotlight look for solid science that backs any claims. With this one, there’s nothing available.

The Bottom Line – Does Raspberry Ketones Work?

Now the moment you’ve been waiting for. Here is our bottom line on raspberry ketones. We like that it’s readiliy available and that we found some positive customer comments. On the other hand, we have some concerns because it’s not backed by any solid science. Moreover, we’re also skpeitcal about this one due to discouraging customer comments and that it’s considered a fad ingredient.

If you’d like to drop more weight, we suggest going with a product that is backed by solid clinical research, supported by encouraging user reviews and gives you a lot of bang for your buck.

Among the best products we’ve seen in 2016 is one called Leptigen. Its formula contains four clinicially-tested ingredients, which have been shown to help speed up fat loss and boost metabolism. There’s no talk of harmful side efffects and the comments around the web indicate people are seeing great results.

The makers of Leptigen are so confident in their supplement, that they’re offering a Special Trial Offer.

How Does Raspberry Ketones Compare?

Previous Raspberry Ketones Review (Updated August 26, 2015):

What You Should Know about Raspberry Ketones

Raspberry Ketones are one hot ingredient in the weight loss world right now. The push behind this ingredient is a series of clinical studies claiming raspberry ketones will increase fat loss, naturally, without stimulation. The studies have been completed on animals so the effect on humans may not be as prevalent, but that does not take away from the buzz. The power of raspberry ketones rests with adiponcetin. The more adiponcetin available in the body, the less body fat.

List of Ingredients

Ingredients:

  • Raspberry Ketones

Product Features of Raspberry Ketones

The inner workings of raspberry ketones are rather simple. According to animal research, raspberry ketones increase adiponcetin. When there is more adiponcetin is the body, fat loss tends to occur rapidly. Many of the clinical studies involve feeding rats a high fat diet before giving them injections of raspberry ketones. This raises a red flag. If the clinical studies are based on injections, does the dieter have to take the supplement via injection to promote fat loss?

There is another problem with the ingredient. We found reference to a human study that was not published officially. The study showed minimal differences in humans taking raspberry ketones and those taking a placebo. Much of the information online about the ingredient comes in the form of personal accounts from dieters having taken the supplement. While this information is important, without clinical studies supporting raspberry ketones specifically, there could be a number of reasons why these dieters lost weight taking the ingredient or a supplement containing the ingredient.

The placebo effect is strong and can be enough to promote weight loss. Dr. Oz, a celebrity doctor and weight loss expert, claims raspberry ketones work to reduce body fat. This support may be more than enough to promote the placebo effect in dieters.

Advantages of Rapsberry Ketones

  • Animal studies show fat loss after taking the supplement.
  • Supported by Dr. Oz.

Disadvantages of Raspberry Ketones

  • No clinical studies on humans are available.
  • One human study showed no significant weight loss (not published.)

Conclusion

There are plenty of clinically proven weight loss ingredients, including chromium, caffeine and green tea. If a supplement contains raspberry ketones along with these ingredients, we are all for trying the supplement, but only if the proven ingredients are included in proven amounts. Too many supplement companies will list clinical data supporting a supplement, only to list ingredients in a proprietary blend.

Dieters need to increase exercise and decrease food intake to lose weight. The effect of raspberry ketones is not strong enough to help a dieter lose weight without strong life changes. With future human studies, we may support raspberry ketones, but as of now, there are no studies to support any effect on humans.

    I began taking this product with little expectation, and observed no results for the first week. However, after taking this consistently for 3 months, I am thrilled with my results. I have been the type who religiously works out 3 times a week, but with a pear shaped body, really has trouble targeting problem spots like butt and thighs. In combination with working out about 3 hours a week, as well and a diet high in protein, I have burned off so much fat that I thought I’d never see go! I am so glad I’ve found this supplement, and found the right healthy lifestyle needed to see the results. I recommend for people who want to loose inches in problem spots. Not really for people who just want a flat tummy.

    A few of my concerns: I have been noticing some bruises on my legs and sometimes arms since using this product. Not sure if it’s the workouts or if the product is causing me to bruise easily. SOMETIMES, it can slightly upset my stomach if I take it without food.

    In order to see results, you need to take these for awhile I have found. Also make sure you check the ingredients. The ones that contain green tea, caffeine, and other stimulants are not so great for you. Pure raspberry ketones are what you want. It works well for people who have low Adiponectin, a protein used by the body to regulate metabolism. If you don’t have low levels, it may not help you. Your lack of weight loss could be due to eating habits, your thyroid, stress, poor blood sugar regulation, or other hormonal imbalance. You can’t take these and not eat properly. Sugar is the biggest cause of weight gain, that and eating too many high glycemic foods (breads, pasta, alcohol, candy, white rice…). So check the type you are taking, and check your diet and have your doctor check your hormones. Lack of sleep, stress, and poor eating cause tons of problems with weight loss.

    I have been taking raspberry keytone supplements for just 2 weeks and I have concerns over it being a strong diuretic as I am up half the night sometimes 5 times to pee and I also experience over acidity and heart burn most evenings. Weight loss is not just about water loss but I wonder whether taking it following an eve meal is a good idea especially with the caffeine content. Any thought?

    [Reply]

    Leanne

    I started taking them yesterday. Today, I took one with breakfast and one with lunch. It’s not even 2pm yet and I’ve had to pee about 10 times today already. I’ve been drinking a lot of water, but I do that usually anyway and never have to pee this often. I’m thinking that either these pills are a strong diuretic or I’m pregnant.
