Not just you want weight loss .
More than a third of Americans are overweight, and another third are obese .
Only 30% of people have normal weight, the rest are overweight with bad health.
The problem here is that weight loss methods are too difficult and harsh, so 85% of people often fail in the process of implementation .
However, there are many types of products that can help you lose weight easily.
These are herbs in the form of pills, which are supposed to help you burn fat or reduce your appetite.
Among them the most famous is an additional food called raspberry ketones.
Raspberry ketones are claimed to cause fat cells to break down more fruit, helping to burn fat faster. It is also confirmed to increase levels of adiponectin, a hormone that helps regulate metabolism.
This article is based on current scientific studies of ketone raspberry fruit and whether it really works.
What is raspberry ketones?
Xeton raspberry is a natural substance taken from red raspberries, and smells very fragrant.
It also has a small amount in black raspberries, cranberries and kiwi.
This fruit has been used for a long time in cosmetics, and is an ingredient added in soft drinks, ice cream and other processed foods.
Actually most people have eaten a small amount of ketones of raspberry or from similar fruits .
It has recently become famous and is considered a dietary supplement.
Although the word "raspberry" can appeal to people, functional foods really do not originate from raspberries.
Ketone extract from raspberries needs quite expensive, because you need it 41kg Raspberries to get the amount needed for a single dose
In fact, 1kg of raspberry fruit contains only 1-4mg of raspberry keton, accounting for 0.0001 - 0.0004% of the total weight.
Raspberry ketones in functional foods are synthesized through a process of industrialization Not from nature .
Another reason that adds to the appeal of this product is the word "ketones" - related low carbohydrate diet , forcing the body to burn off excess fat and raise blood levels.
However, raspberry ketones have nothing to do with low-carb diets and do not have the same effect on your body.
Summary: Xeton raspberry is a compound extracted from raspberries with delicious taste. One study found it used in cosmetics, food processing, functional foods that support weight loss.
How does raspberry ketones work?
Researchers are very interested in raspberry ketones because of its molecular structure.
They found that it looked very similar to the other two molecules (found in chili) and (a kind of stimulant).
Some studies have shown that these two molecules can promote metabolism . Therefore, it can be speculated that raspberry ketones also have similar capabilities.
When the researchers took fat cells from mice and made them grow in vitro, they added raspberry ketones and had two effects :
- Increase lipolysis (fat breakdown), primarily by making cells more sensitive to the effects of norepinephrine-burning fats.
- Make fat cells release more hormones adiponectin than.
is a hormone made by fat cells and is thought to play a role in regulating metabolism and blood sugar.
Thin people have much higher adiponectin levels than those who are overweight; and hormone levels will also increase when people lose weight .
Studies have shown that people with low adiponectin levels are at risk for obesity, type 2 diabetes, fatty liver, and even heart disease .
Therefore, raspberry ketones are used for reasons of increasing adiponectin levels by natural methods to help people lose weight and reduce the risk of many diseases.
However, even when raspberry ketones increase adiponectin in fat cells in mice, it does not mean that they can do the same thing in other living and breathing organisms.
However, there are many other natural ways to increase adiponectin. For example, exercise can increase adiponectin levels by 260% for at least a week. Drinking coffee can also increase higher .
Summary: Raspberry ketones have a molecular structure similar to the other two fat-burning compounds. They can isolate and break down fat cells and burn them, producing a hormone called adiponectin.
Some studies show that raspberry ketones work on mice, but at extremely high doses
Functional foods containing raspberry ketones show some promising effects on mice.
However, the results are not nearly as impressive for functional food manufacturers as they believe they work.
In another study, one type of rat was fed an unhealthy diet. Some of them were used to raspberry raspberry supplements, some did not .
And this is what happened:
As you can see, the group of rats treated with raspberry ketones weighed only about 50 grams after the end of the study. The remaining ones without raspberry ketons weigh about 55 grams (about 10% difference).
Note that mice in the industry did not lose weight, they only gained less weight than expected.
Another study conducted on 40 mice was also fed a high-calorie diet. In this study, mice treated with raspberry ketones increased adiponectin levels in the body and were protected from fatty liver disease .
However I think you should not hope through this incident, because this is the dosage used extremely big .
You will have to use 100 times the recommended amount to achieve the same results as an animal test (not recommended).
Summary: Some studies in rats show that raspberry ketones can help fight weight gain and fatty liver. However, the studies all used raspberry ketones in large doses, much higher than those used in functional foods.
Does ketone raspberries work on humans?
Unfortunately No studies yet about ketones raspberry on humans.
Only one study on humans can use substances including: coffee, ketones, raspberries, garlic, capsaicin (a substance extracted from chili), ginger and synephrine (a substance that helps reduce fat) .
Within 8 weeks of study, participants lost 7.8% fat, compared with only 2.8% for placebo groups (both groups cut calories and exercise).
However, it is also possible that raspberry ketones do not affect that weight loss. It may be due to caffeine or a certain herb.
In fact, I have been studying for a long time and thoroughly, and can confirm 100% that there is no real evidence of ketone raspberry effect on humans.
From searching on forums and rating online, it seems similar to other supplements for weight loss. Some people lose weight, some don't, some even gain weight while taking it.
It is important to note that it is not only because someone on TV or anyone you know is losing weight thanks to raspberry ketones does not mean that any functional food will work.
Even if people are down, it's probably just a placebo effect.
Many studies show that can affect people's health.
Perhaps if people want these drugs to work, they should pay more attention to their body weight and diet so they have the motivation to exercise.
Therefore, it is possible only by these habits to help lose weight, not to use any functional food.
Of course, it is possible that raspberry ketones do not work, may not be mentioned, but when used in such large doses you should consider the consequences, I personally think this is not should do.
Summary: At present, there is not much evidence of raspberry ketone effect in weight loss.
What are the other benefits of raspberry ketones?
Another study has shown that raspberry ketones are useful in the cosmetic industry.
It has been shown to improve hair growth in people with hair loss, increase skin tension and elasticity in women .
However, the scale of this research is small and there are a few errors. Therefore, it should not be put into widespread use .
Summary: A small study showed raspberry ketones when used and properly managed, can help grow hair and improve skin elasticity.
Side effects and dosages
Because it is not studied in humans, there is no evidence of its potential side effects.
However, when used as a food additive, raspberry ketones are classified as FDA's "safety certification" (GRAS).
Remember that FDA also ranks high fructose corn syrup and soybean oil in the same category, so half believe it.
Overall, there have been some reports of myocardial infarction, tachycardia, hypertension, but this may be a coincidence.
Studies in mice used large doses and no side effects were noted, so it may be safe to be tested in animals.
Because there are no human studies, there are no data on the side effects and recommended doses for humans.
Recommendations for the use of raspberry ketones in doses ranging from 100mg - 400mg, 1-2 times a day.
Summary: Because there are no studies in humans, there is no information about the side effects or recommended doses on scientific evidence.
Should you try raspberry ketones?
Of all the weight loss supplements I have reviewed (including Yacon Syrup and Garcinia Cambogia), raspberry ketones are the kind that brings least effective .
They work in isolated fat cells and are tested in animals in large doses, but this is completely unrelated to the recommended dosage for humans.
The fact is that we need such strange doses to achieve fat burning in animal studies. I suspect that raspberry ketones will have any significant impact.
Thinking about the benefits of self-testing, I tried raspberry ketones for a few days. The only effect I have is heartburn.
If it smells and can't be controlled, it can be a problem for your life, so raspberry ketones are probably something you might want to consider.
But if losing weight is your goal, you will probably lose more from burning calories when you walk to stores and buy drugs, rather than just taking medicine.
Raspberry ketones not only consume time and money, they also distract you from doing things that really matter, change in the long run, and benefit your life.
One day we can find a functional food that really helps with long-term weight loss, but this is absolutely not with raspberry ketones.
