If you need to lose weight, you’re not alone.
More than a third of Americans are obese, and another third are obese (1).
Only 30% of people are now at a healthy weight … overweight, the new has become “normal”.
The problem is that conventional weight loss methods are so severe that 85% of people not in the long term (2).
But … there are many products out there that are claiming to make things easier.
These are herbs, shakes, drops and pills that will help you to burn fat or to reduce your appetite is.
Among the most popular is called Raspberry Ketones a supplement.
Raspberry ketones claimed to cause the fat cells to be broken more effectively, helps the body to burn fat faster.
They are also alleged to increase adiponectin, a hormone that helps regulate metabolism.
This article reviews the current scientific research behind Raspberry Ketone supplements and if they are really worth considering.
What are ketones Raspberry?
Raspberry ketone is a natural substance that gives red raspberries their rich flavor.
This substance is also found in small amounts in, cranberries and blackberries kiwifruit.
It has a long history of use in cosmetics and has added to soft drinks, ice cream and other processed foods as a flavoring agent.
Actually … that most people are already eating small amounts of raspberry ketones, either from the fruit itself or due to their popularity as a flavoring agent (3).
More recently, they have been popular as a weight loss supplement.
Although the word “raspberry” can respond to people who supplement is not really derived from raspberries.
Extract Raspberry ketones from raspberries is insanely expensive because you get £ 90 (41 kg) of raspberries, the amount needed for a single dose!
In fact, a kilogram (2.2 pounds) whole raspberries contains only 1-4 mg of raspberry ketones. This is 0.0001 to 0.0004% of the total weight.
The raspberry ketones They are found in supplements is manufactured synthetically by an industrial process and are not natural (4, 5, 6).
“Ketones.”, They burn with low-carb diets that force the body fat and increase the blood levels of associates - Another reason for the attractiveness of this product is the word “ketone”
However raspberry ketones have absolutely nothing to do with low-carb diets and will not have the same effect on the body.
Have Raspberry ketones work in humans?
Unfortunately, there is not a single study of raspberry ketones in humans.
The only human study that comes close, uses a combination of substances, including caffeine, raspberry ketones, garlic, capsaicin, ginger and synephrine (19).
In this 8-week study, participants lost 7.8% of their fat mass compared to the placebo group, which lost only 2.8% (both groups also calories and exercise).
However, it is very possible that the raspberry ketones had nothing to do with it. It would have the caffeine or any of the other herbs.
Really … I looked long and hard and I am 100% sure that there is no actual evidence that this supplement may work in humans.
From looking at forums and reviews online, the pattern seems similar to other weight loss supplements. Some people lose weight other not, and some people even gain weight while taking the supplement.
It is important to note that just because someone on TV or someone you lost weight with raspberry ketones easy to hold, it does not mean that the supplement had nothing to do with it.
Even if people lose, that it’s just a placebo effect are the chances.
Many studies show that a placebo (dummy pill) can have an impact on people.
Maybe they want the pills to work, so that they themselves often, mindful eating weighing motivated to exercise feel more start etc.
Therefore, it might just those behaviors that are caused to lose the people, by weight, not the supplement itself.
Of course it is still possible that raspberry ketones work, that it was just not yet proven, but since … how incredibly large dosages must be to see an effect, then I personally think this is unlikely.
There is currently no evidence that raspberry ketone supplements can cause weight loss in humans.
Raspberry ketones are other benefits?
A study has shown that raspberry ketones may have cosmetic benefits.
In the case of topical administration as part of a cream, has been shown to increase hair growth in persons with hair loss, and to improve the elasticity of the skin of healthy women (20).
However, this study was small and had a number of weaknesses, so it should not be used as evidence of nothing (21).
Conclusion: A small study shows that raspberry ketones, when administered topically, can enhance and improve the elasticity of the skin hair growth.
Woman skeptical about a pill.
Because it has not yet been studied in humans, there is no data on the possible side effects.
But as a food additive, raspberry ketones are considered by the FDA “generally recognized as safe” (GRAS).
Search online, there have been some anecdotal reports of tremors, rapid heart rate and increased blood pressure, but this could be a coincidence.
The mouse and rat studies used massive doses, and no adverse effects were noted, it seems to be safe in laboratory animals.
Due to the lack of human studies, there is no scientifically proven recommended dosage.
The recommendations on various raspberry ketone supplements in the range of 100 mg to 400 mg, 1-2 times per day.
If you, although they do not want a shred of evidence that they work, buy raspberry ketones, then there is a pretty good selection on Amazon, with thousands of reviews.
