Has anyone tried Rasberry ketone ?

My friend claimed it helped her not gain more weight. But there have been zero human studies on if it does anything. I am sure you'd have a nice placebo effect.

I am taking them sometimes( its not a diet pill its a component of raspberries and you would need to eat a crazy amount like 20 lbs for it to burn fat but the component is extracted and put into a supplement)..You need to also watch exercise and diet..I saw the dr Oz show and all the research..It cant hurt you thats for sure..Just make sure to do everything else..I think its aids in losing fat..I dont need to be attacked for my opinion..keep it to yourself

I saw that show too and Dr.oz didn't present any research.

I have been a regular member on MFP for almost 3 yrs now... I had lost 45 lbs and then gained back the weight due to surgery... I am not someone who will opt for pills but lately my weight is stuck... after eating healthy n exercising.. so now I m trying to look something that I can take for a month or so to kick start the weight loss again...

Your weight is stuck...after eating healthy.... :huh: Checked your diary, your daily goal is only 1000 calories, which is NOT healthy, and the only day where I see food logged you came in at around 900.

I would say if you truly are wanting to eat healthy and lose the weight, you need to do your homework and figure out how much your body really needs, and don't make such drastic cuts in calorie intake.

Avoid pills and "diets", use any of the numerous resources here and at other reputable online sites where you can easily enter your info and calculate your caloric needs. My favorite topic here at MFP is this one: http://www.myfitnesspal.com/topics/show/912914-in-place-of-a-road-map-3-2013

Why eat so little and turn to pills when you can eat a good amount of delicious food that fits into your lifestyle, and is sustainable for fat loss and fitness for the rest of your life? Temporary changes will only get you temporary results. Ditch the raspberry pills and green coffee bean gimmicks, save your money for real food that nourishes your body and fuels you for workouts and daily life. Eat too little for too long and you're just giving your body a reason to store fat and slow your metabolism.

Copy/Paste from my post on this thread in the other Topic: also includes info on Dr. Oz at the bottom.

Just to provide some information and correct some misinformation. First and foremost - Weight Loss and Healthy Living is 85% Food and 15% Exercise. Your primary results will come from focusing on these first!

Research any product before you purchase, let alone ingest!

For ANY supplement:
Always, never expect a “miracle in a bottle”!
This can lead to disappointment, and disappointment is the killer of weight-loss! Keep expectations in check with a realistic outlook. Results always vary and are usually of a small percentage (which may over time contribute to slightly better results).
There are supplements that can "help" the body perform functions it should already be performing, like taking Vitamin D to help absorb calcium (you still have to consume calcium for the Vitamin D to do anything). That does NOT mean that you can just take a pill and lose 50 lbs and gain muscle – you still need to make better food choices and exercise for sustained changes.

How Raspberry Ketones are supposed to work:
Raspberry Ketones are made 100% from raspberries (ketones are the primary “aroma” compound of raspberries – it’s what gives raspberries their distinctive smell) and currently have no side effects. Raspberry Ketones are supposed to work by essentially tricking the body into thinking it’s thin by increasing the levels of a hormone known as Adiponectin. The Ketones have been shown to increase both the expression and the secretion of Adiponectin, an Adipocytokine (cell-to-cell signaling protein) mainly expressed and secreted by Adipose tissue (the tissue that stores fat). Adiponectin levels can also be increased in the body by consuming Omega-3 fatty acids (such as Eicosapentanoic Acid (EPA). http://www.ncbi.nlm.nih.gov/pubmed/20425690

So far the only studies concerning Raspberry Ketones are with mice. In the studies the Ketones increased secretion of Adiponectin, and appeared to prevent fat gain and increased fat oxidation (burning).

The Adiponectin protein hormone is involved in a number of metabolic processes, such as glucose regulation and the metabolism of fat for energy production. Levels of Adiponectin are inversely correlated with body mass index (BMI). Basically, thinner people have higher levels of Adiponectin than obese people. This hormone also seems to play a role in helping to stave off or ameliorate disorders such as obesity, diabetes, cardiovascular disease, atherosclerosis (hardening of the arteries), inflammation, and what has come to be known as Metabolic Syndrome.

Unfortunately, when a person becomes obese the hormone levels drop or becomes “sluggish” because of all the fat it is trying to burn. Essentially, being overweight is exhausting your metabolism. When active the Adiponectin causes fat cells to release their fat and shrink (much like a deflated balloon). Raspberry Ketones are supposed to stimulate the adiponectin thereby boosting metabolism, burning the stored white fat cells, as well as decreasing blood sugar through increasing the release of insulin.

“Researchers at the University of Pennsylvania School of Medicine have established in an animal model that the hormone adiponectin secreted by fat tissue acts in the brain to reduce body weight. In contrast to leptin, a related hormone, adiponectin can cause weight loss by raising metabolic rate while not affecting appetite. ...

When adiponectin, which is involved in glucose and lipid metabolism, was introduced into the cerebrospinal fluid of normal mice, they showed no changes in food intake, but their metabolism rose. "The animal burns off more calories, so over time loses weight, which was very fascinating because we knew that leptin caused weight loss by suppressing appetite and increasing metabolic rate," explains [lead author Rexford] Ahima. "Here we have another fat hormone that can cause weight loss but without affecting intake."

For many dieters, it's easy, at first, to lose weight; but over time, it becomes more difficult because the body compensates, in part, by dropping its metabolic rate. "Adiponectin or its targets in the brain and other organs could be harnessed to sustain weight loss by maintaining a high metabolic rate," says Ahima. "This is only a possibility. We're not suggesting at this point that adiponectin will become a drug." In severely obese mice, adiponectin rapidly decreases blood glucose and lipids, while burning fat. Hence, adiponectin could be beneficial in the treatment of diabetes and heart disease associated with obesity.”

Some other studies are showing that women with Alzheimers Dementia and Elderly men with Osteoporosis have increased levels of Adiponectin. It is believed that this occurs if the body becomes hormone resistant to Adiponectin, but further research is needed.

Why not just eat raspberries?
Because for every 1 kg of raspberry only 1-4mg (depending on the harvest) of Ketones are extracted. You would have to eat 90-500 lbs of raspberries to get 250mg of ketones.

Recommended Dosage:
There is no real recommended dosage. It ranges from 100-500mg per day. There are also capsules that are made from Raspberry Extract (instead of Ketones) which yield minimum Adiponectin increasing properties. The extracts will appear as brownish-red powder as opposed to a white powder. Pure Raspberry Ketones will be white in color.

Summary
Essentially, you are trying to consume a concentrated food that may increase the Adiponectin level, but by how much is still unknown.

Other nutrition-related tactics to up this fat-burning hormone include:
• Make protein a priority. Eating adequate lean protein from lean meat, chicken, fish, beans, peas, legumes and whole grains because hormones are made from protein.
• More Omega-3 please. Increasing the amount of omega-3 fatty acids in your day by choosing fatty fish, walnuts or almonds, and flax or chia seeds. It is also important to watch your intake of omega-6 fatty acids from corn, soybean and safflower oils.
• Drink coffee! Coffee drinkers who drank 1-2 cups (6-12oz) of coffee per day had the highest levels of adiponectin among coffee and non-coffee drinkers.
• Move more. 40 plus minutes of aerobic, heart pumping exercises, like brisk walking, jogging, biking climbing stairs, jumping rope, dancing, or swimming, per day, at least 4 times per week also will encourage the body to make more adiponectin.

Dr. Oz (where a lot of supplement attention comes from lately):
Dr. Oz does not endorse or produce any products. Anything with his name or picture on it is being used without authorization - so you don't want to buy those. Dr. Oz does not promote any specific products and does not make money from selling products - he makes money from advertising slots based on number of viewers just like every other talk show. He continually talks about weight loss and labels too many products with hype inducing names like "miracle in a bottle". That does not negate the actual product but does tarnish his name/show as over promoting these products to gain larger viewership. Just like local news stations will hype the ‘What’s killing your kids? Tune in at 7 to find out!’ Dr. Oz uses key phrases and sensationalism to grow and keep a large audience base.
Dr. Oz has a link for reporting any products or companies that are using his name or picture here: http://www.doctoroz.com/blog/mehmet-oz-md/my-name-profit-not-anymore

Normal disclaimer:
There are no indications of any harmful side effects. As a precaution: The supplement is new, and there is no research on its effects on children. Therefore young people under the age of 18 and pregnant or breast feeding women should not take this supplement. You also shouldn’t take this if you have an allergy to raspberries.

Again: Research any product before you purchase, let alone ingest!

No! I do not sell anything myself, I just did my own research on it when I heard about it. Weight loss is 85% food and 15% exercise. Eating healthy will always have a greater impact than any supplement (except maybe crack cocaine or meth). Something like this may provide only fractions of a percentage towards weight loss - and sometimes those small percentages add up over time. You have to balance cost vs possible results vs possible disappointment if you expect too much from it.

Here you go. This makes sense..Its all hogwash!! i was duped..Soemtimes i am so gullible. :blushing:

http://en.wikipedia.org/wiki/Raspberry_ketone

Was just reading through this article. I have submitted a request to update/modify a small part of it (as the article is locked due to spam).

Under Putative health effects it currently states: "A more recent study demonstrated that when mice were fed very high doses of raspberry ketone, up to 20 g/kg, 2% of body weight or 4761 times greater than estimated human intake, there was a statistically significant prevention of high-fat-diet-induced elevation in body weight.[11] "

The reference #11 above (http://www.sciencedirect.com/science/article/pii/S0024320505001281) concludes: "RK prevents and improves obesity and fatty liver. These effects appear to stem from the action of RK in altering the lipid metabolism, or more specifically, in increasing norepinephrine-induced lipolysis in white adipocytes."

Seems like this should be made clear in the article. Also adding a section from my above post: There is also another/related source that can be added for this study: http://www.ncbi.nlm.nih.gov/pubmed/20425690

Also under same Topic, This may provide a better explanation of how it is supposed to work. Whether eventual studies change over time, this is the basics: The Ketones have been shown to increase both the expression and the secretion of Adiponectin, an Adipocytokine (cell-to-cell signaling protein) mainly expressed and secreted by Adipose tissue (the tissue that stores fat). Adiponectin levels can also be increased in the body by consuming Omega-3 fatty acids (such as Eicosapentanoic Acid (EPA).


Also, This statement is being challenged to provide clarity: Early studies in rats looking into the potential toxicity of raspberry ketone found no effects on the body weight of rats with doses up to 100 mg/kg, 238 times greater than the estimated intake for humans or 0.01% of body weight.[10]

• The rat study was in 1970. While it could have contained findings contradicting the 2005 mouse study, it obviously was not testing the same hypothesis nor was it even in the same model system.
• The dosages used in the rat study while being 200 times human intake are infinitesimal compared to the 4700 fold increase used in the mouse study.


I just want accurate information, I'm not trying to be "blinded" about raspberry ketones - there is still not a human study to confirm any potential weight loss results, but some of these other statements are misleading.
