Does it Work? - Raspberry Ketones?

View Full Version : Raspberry Ketones?

02-06-2012, 06:49 PM
I was watching Dr. Oz today and he said that taking 100-200 mg of raspberry keytones a day with a healthy breakfast can help with weightloss (along with your healthy diet and exercise regime of course). Has anyone tried this and does it work?

02-06-2012, 07:24 PM
I've read about it, and there have been no human trials, and not even a lot of animal research. It apparently works in mice, and people using it says it works. How it is supposed to work on fat break-down in mice involves its effect on norepinephrine ( supposedly stimulating norepinephrine release).

I couldn't find enough information to consider it safe. Norepinephrine is both a hormone and a neurotransmitter, so I didn't feel it was something to "mess with" without a whole lot more research.

It concerns me that Dr. Oz. seems to reccommend or at least partially endorse the use of so many supplements. Supplements are still chemicals, so they should be treated like drugs. The difference is that drugs have to be proven safe before they can be sold, whereas supplements from "natural" sources have to be proven unsafe before they can be taken off the market.

In my experience, from what I've studied, all of the substances that truly improve metabolism and fat-burning have potentially dangerous side-effects.

This might be the miracle exception, but I'd rather not be a front-line guinea pig.

I do take quite a few drugs and supplements for my health issues, so I'm not being hypocritical - all those that I've added have been well-researched, which is why I felt safe in taking them at my doctor's reccomendations or after asking my doctor if I could take them after reading the research.

To some degree I have to be scientist and lab rat with my health and weight (as we all have to be). I'd just rather not be in the front-line so to speak. I'd like to see more animal studies and human studies before throwing it into the chemical cocktail I'm already on.

Thanks for the reply! I'm usually weary of supplements myself, especially ones that haven't been more researched, but I figured since it was Dr. Oz endorsing it that maybe it would work... and he seemed really adamant about it working. I'll have to do more reading up on it before I decide anything :)

02-06-2012, 07:47 PM
Dr Oz definitely seems to have gone the way of quackery lately and I'd be wary of anything he recommends.

02-06-2012, 07:57 PM
My concern with Dr. Oz, is his reputation makes people trust him more than they should, and believe that anything he says is not only true, it's safe- not because of his medical credentials, but because he is famous (celebrities are usually right, so celebrity doctors must always be right).

There has been a lot of controversy in the medical community about many of the things he has recommended. Firstly, if you took every supplement he recommends or considers interesting, you'd have no room for food. Not to mention that many of the supplements are so concentrated they really need to be considered drugs - and therefore drug interactions have to be considered as well.

Before trying anything Dr. Oz or anyone on tv (or anyone at all, for that matter) recommends in way of supplements or alternative medicine, a person really needs to ask their own doctor (who knows the person's medical history).

On Dr. Oz's website (in extremely small print at the bottom of the screen) is the disclaimer:

This website is for informational and entertainment purposes only and is not a substitute for medical advice, diagnosis, or treatment.

You'll see a similar disclaimer on the television show, which basically means "if you try this at home, you're on your own - consult your doctor or take your chances."

And yet, folks still assume that if it's on tv, and someone as famous and apparently nice as Dr. Oz is recommending it, it must be effective and safe.

It's not so, though a lot of people will be mad at me for saying so. I find Dr. Oz very entertaining, I watch the show - and when I see something interesting I research it online, and then if it still seems promising, I ask my doctor, and that's what everyone needs to do.

I can tell you that my own doctors don't have a very good opinion of the show, because it encourages people to try treatments that can be dangerous. Even when Dr. Oz warns against a potentially dangerous treatment, the number of people who try the supplement or procedure drastically increases (and even more so if Dr. Oz is only mildly skeptical and exponentially more if he endorses it).

People do seem to assume that if it's even mentioned on Dr. Oz it must be effective and safe.

Before adding any supplement, a person should talk to their own doctor - even if they're very young and healthy, but most especially if a person is on any other supplements, tc or prescription medications or has any health issues or medical conditions,

02-06-2012, 08:06 PM
Another thing to always keep in mind with edutainment shows, the entertainment trumps the education, because ratings keep a show on the air.

Every medical and informative talk show I've ever watched on tv has gotten nuttier and nuttier over time - because the headlines have to be more and more sensational to hold people's interest. Once you've dispensed with all the common sense advice, you've got to keep bringing in new stuff to hold the audience's attention - because people don't want the same common sense information repeated constantly - they want "new" and "more exciting" stuff.

Entertainment not only comes first (or there would be no show) - truth gets obscured and even destroyed in the process.

02-06-2012, 08:49 PM
You ladies are very right and I feel foolish now to think that just because Dr. Oz endorses them that they are good for me. I definitely need to consult my doctor first. I was just curious to see if anyone had tried it :)

02-06-2012, 11:32 PM
Remember too (this is probably obvious, but for anyone reading who might forget) that even testimonials from random people don't mean much, either in effectiveness or safety. Just because you meet people who tried it, think it works, and haven't noticed any side effects yet - also doesn't mean it's safe.

A lady made up a diet based on Atkins, but with virtually no fat, and under 500 calories. It even got into Woman's World magazine. I can't even tell you the name of the diet, because this websites censor will censor it out. She claimed to have lost over a hundred pounds on the diet (turns out she didn't). She used false testemonials on her site, and the diet was so dangerous that multiple people became quite ill and at least one person died on the diet - and yet you will still find people who defend the diet, because they lost weight on it, and didn't happen to experience the organ failure or other terrible side effects that were common.

Her virtually no-carb, no-fat diet wasn't "new" it has been called "rabbit starvation" and doctors, dietitians and history buffs have known of it's extreme dangers for 150 years or longer. Early pioneers discovered that a diet of animal protein but extremely low in fat and carbohydrates was dangerous - often allegedly killing people faster than having no food at all. They named it "rabbit starvation" because it was seen in people on wagon trains who had run out of supplies in locations or during seasons when rabbits were the only available food source. Rabbits are very lean animals, and without fat or carbohydrates, a diet of only rabbit (or other lean animal protein) causes extreme illness relatively quickly. Probably electrolyte depletion or imbalance is the biggest risk - which can cause cardiac arrest.

Cruelly, the woman that created this diet (that she obviously wasn't following herself, when private investigation determined that she was not only still very overweight - she also used fraudulent, stolen photos and testimonials on the website, and would kick people off her website if they disagreed with her, without refunding the lifetime membership fees the people had paid) told people that the signs of illness were signs that the diet was working (the first symptoms being constant nauseousness).

To this day, there are people who will religiously defend the diet (which is also a reason people often will not criticise a diet, even if they almost died from it).

Hearing someone say (especially from someone we know or trust) "I've tried it, and it worked for me, and I didn't get ill or hurt (at least I haven't yet or don't think I have)" isn't a very good testimonial - even though we all tend to be persuaded by such arguments It's natural for us (probably all mammals, and maybe birds and reptiles too) to think "if a creature sort of like us ate it without apparent harm, we probably can eat it too," but that's not an ironclad strategy. Evolutionarily it's a better strategy than nothing, but it's not as good as good science. We're just not used to thinking in terms of science.

When you look at drugs that have been pulled from the market, or are endanger of being pulled from the market because one person in every ten thousand or even fifty thousand has a terrible reaction to it, you see why testimonials don't really help much. And yet, our human instincts persuade us that if even three or four people tell us they've had luck with it, we're very likely to consider trying it (even if we're told that people we don't know were harmed by it. Even if we're told that a lot of people were harmed by it).

If we hear that 9 people out of 10 die from something, but we know only people who have done it and not obviously been hurted, we tend to think of it as safe, even if we really know better.

I think that's part of the problem with the entire obesity "epidemic," we know being overweight has some very severe health risks, but we see fat people every day (more and more every day) who seem relatively healthy, so we start to think that "it can't be that bad."

And on the other hand, we're also taught to consider severe obesity a fate so much worse than death, that the risks really don't matter. To this day, even though I've tried to research it, and have asked my doctors (who agree with me) there's no way to tell whether the health issues I have and the damage I've done to my body was done by the obesity or by the radical and dangerous methods I used to attempt to lose the weight over the years (probably a combination of both).

I saw "raspberry ketones" and knew someone watched Dr. Oz yesterday!

I also think he goes a little nuts with the supplements - if you took all the ones he recommended you'd have to start swallowing pills in the morning and not stop until you went to bed!

Anecdotal evidence is not scientific evidence. T

hat woman's clients were taking them, sure, but what else were they doing? They were working out and eating right (even though they didn't say that explicitly, the pictures were of them in a gym!)

It might just be the placebo effect!

Something that would require 90 lbs of whole raspberries to replicate is not something that is vital to the process, IMO.

I watch his show, but I listen to him with an entire mountain of grains of salt...

02-07-2012, 01:47 PM
Informative post, kaplods!

I know the diet you are talking about, it starts with a K. I believe there are many lawsuits against this woman. If I remember correctly, she stole her 'after' photos from a Russian male order bride website.

When I first heard of the diet, I wondered how people could not see the danger in it and why no one was suspicious of the fact that people get banned from the support site for questioning the diet or stating they got sick on it.

02-07-2012, 02:27 PM
I'm usually sitting through Dr. Oz's drivel due to my mother's insistance to watch it. The show seemed interesting early on but he's slowly gone downhill and off onto a quest for more viewers. Each and every show seems to be about a magic way to lose weight.

I have to say though, there is about 5 minutes worth of good stuff on his show every so often. Maybe a good recipe here and there to try. It's not really worth it to watch his entire show though.

Kaplods has given more insight into this than I ever could, but just know this: if it seems too good to be true, it probably is. There is no magic diet, there is no magic pill. Good old fashioned hard work is how you lose weight.

When I first heard of the diet, I wondered how people could not see the danger in it and why no one was suspicious of the fact that people get banned from the support site for questioning the diet or stating they got sick on it.

I think some people are so desperate for an easy way to lose weight that they'll try anything and ignore the warning signs.

02-07-2012, 02:33 PM
Well...sheepishly, I admit I ordered them. BUT!!!!!

I feel like I need a little help. I know my hormones are out of whack of from BCP, or at least I suspect they are. I didn't have issues losing weight until I started taking it again, and years ago BCP is what had me gaining pound after pound in the first place. In any case, without boring you all with the details, I figure with my current strict diet and strict workout regime, a little experiment with raspberry ketones may be just the ticket.

But I am skeptical. And yeah, I agree that you really have to watch Dr. Oz and all his supplements. I'd rather eat my supplements, thank you. But this one...I don't know. I know what it's like for a previously fat persons body to continue behaving as if it's fat. The idea that my body may act as though it's thin again...that sounds refreshing.

I'm giving it a try.

P.S. I've been waiting for just such a thread today. ;) I too just knew there were some fellow Dr. Oz watching friends out there. :D

02-09-2012, 06:04 PM
I know a bit about ketones, my boyfriend is doing his master degree on a project based on ketosis.

Ketones are a source of energy that the body can rely on when the body is lacking glucose (exemple : starvation mode, or diabetics person). Some studies also showed that the use of ketone can even be more effective as an energy source than the actual glucose (like workout training in starvation mode, in experimental studies)...

ONLY if the person is lacking glucose though.

If the person as glucose in the food intake, the body won't use the ketones (that are produced by your own body during a process following starvation of deprivation in glucose). So if you take a ketone supplement, your body just won't use it...

I look for the product on the Internet and I wouldn't trust it, they don't say what molecules specifically there is in that.

Natural product can be good sometimes, but when they hide what there is in it, it's never a good sign. And most of the time, there was no clinical trial on it.

I don't say it might be dangerous (it's probably not). I just think that it wouldn't worth waisting money on it, in my opinion...

02-09-2012, 07:17 PM
A lot of natural diet products are unsafe, and that's my concern here. Because "natural" supplements don't have to be proven safe to be sold - they have to be proven unsafe (and terribly unsafe) before they can be pulled from the market.

Virtually all of the supplements that have a proven track record as weight loss aids - do have negative and even dangerous side effects.

It almost inevitably turns out that if it's safe - it's ineffective, and if it's effective, it's not entirely safe.

At least with the "proven" supplements like caffeine and other stimulant herbs, the dangers are well-known and well-documented.

I am currently on disability for multiple health problems, and I strongly suspect that some of these issues were caused or severely worsened by decades of "giving it a try."

I really thought "what do I have to lose," because I didn't realize what the risks really were.

We hear "raspberries," and think nothing can be unsafe if it's made from raspberries, but that's not logic, that's emotion.

After all oranges don't have a reputation as being dangerous either, and bitter-orange is a popular weight loss aid (and effective, but at a cost.)

Any substance powerful enough to be significantly effective, is going to have potentially dangerous side effects, which is why it really is so terribly important to talk to your doctor (even if you're not on medications, but especially if you are), and ideally a dietitian too.

Newbie Here - Has anyone tried the Raspberry Ketones that Dr. Oz recommended. Does it work?:?:

02-12-2012, 12:17 PM
I don't have any health issues so I went and purchased a bottle. I'll update with results in a few weeks. I would like to warn that on the show they only recommended 100-200 mg daily but the product I purchased has the dosage at 2 capsules daily and in this case that would give me 400 mg daily of the raspberry ketones. I have opted to only take 1 capsule daily of the product I bought. So far I have not experienced any side effects on 1 pill daily. The first day I took 2 and I did feel slightly jittery but no more than adding a shot of expresso to my coffee. I don't like that feeling so I won't be taking 2 a day.

I am also eating a healthy diet and exercising. Normally in the first 2 weeks I would lose around 6-7 pounds. If I do not lose more than that by adding the ketones then I will have to say this product is pointless. I'l let ya'll know.

03-31-2012, 08:54 PM
I saw this on Dr Oz a few weeks ago but no one in town has this. I would live to try it but I can't remember what mg he recommended how often per day. I'm also leery about buying from Amazon... Has anyone tried it?

Thanks in advance,

03-31-2012, 09:30 PM
ye gods. so much for trying to find objective information.

fwiw, there was a study done in japan in 1955 - the amount that was given to the mice that showed protection against obesity (NOT fat metabolization or burning) was 2% of bodyweight.

that's a lot of raspberries.

03-31-2012, 10:27 PM
I've been taking it for over one month and it really hasn't done anything. My average weekly weight loss has not changed.

03-31-2012, 11:10 PM
What I read a while back in a weight lifting mag said that it showed promise in mice, but was never substantiated in people. You would probably do better to eat a lot of fresh berries instead. These have proven health benefits, and will probably be cheaper and tastier in the long run. If it sounds to good to be true...

Funny, I was just reading an article on Huffington Post about this 5 minutes ago.

Apparently this product has never been shown to work on humans.

Dr Oz disappoints again :(

04-01-2012, 01:22 AM
Theres no magic to weight loss,just control your diet.

04-01-2012, 10:19 PM
Oz did say that it would take like 90 lbs of fresh berries per day. The pills were supposed to be concentrated enough to work. *shrug* I just thought if anyone had tried it, they'd be here. Emmcakes, how much are you taking?

04-02-2012, 10:26 PM
So how did it go Indy?

05-01-2012, 03:34 PM
Hello did anyone try rasberry Ketones yet? :hug:

05-03-2012, 07:54 AM
I looked into it and it appears the only successful studies on it were in rats who had 2% of their daily intake as raspberry ketones. Rats have rapid metabolisms so they are often used as a proof of concept for human studies. The human studies, even with a very high intake, have not produced any results. One article I read said that lemons/limes contain any even higher amount of the lipolysis enzymes, so in theory, drinking lemon juice would be more effective than raspberry ketones.

I must admit I got some Raspberry Ketones after seeing the Dr Oz show.
When I am done with my second bottle I will not be replacing it.
The only thing that I noticed was that when I burped it would taste and smell like Raspberries.

05-16-2012, 02:12 PM
I have been popping raspberry ketones for about a month now. The 1st couple weeks I lost about 10 lbs, but now I am up 5lbs again. I have been taking 100mgs 3 times daily. I was thinking about getting the stronger ones next time. I love the aftertaste and that they are natural. I definintly feel like I have more energy from them, but I am not really sure if they are "shrinking" my fat cells. I am not giving up yet since I did lose some weight, but it could just be my diet and exercise change also.

05-20-2012, 10:45 AM
I'd be willing to try them if I could find an all natural, raspberry extract only product with no caffeine added.

05-21-2012, 10:49 PM
I saw it on DR OZ but i never really tried it..if any good testimonials on it please let me know i might try it :X

06-28-2012, 08:05 AM
I am getting mine in the mail this week. I will let you guys know if it makes any difference. They are very cheap if you know where to find them, so I'm only losing $8 for a 30 day supply, which is fine even if they don't work.
A co-worker who recommended them to me claims to have lost 15lbs or so in the past 2 months with absolutely no change in diet or exercise. We will see.

11-03-2012, 11:54 PM
I'm using them with the liquid l-carnitine. I don't really know how much is them but diet and exercise are part of my routine. I was about 226#s when I started it. Took me to current and it,s been about 2.5 months. I usually can,t lose weight easily i've pcos.
Hope as a test study I help.:)

I am all too familiar w/ PCOS, so you took it and it helped?? Did you change diet and exercise as well?

11-09-2012, 08:32 PM
Hi GHlover. Actually I believe it is but I have severl things I'm doing (with Pcos I get too frustrated w/o the extra help) I am eatting customary breakfasts of glutten free oats with fiber, chia seeds and Spirulina(from health food stores). I add an apple for nutritional purposes and I try to keep on track the rest of the day with lean/porportions in my protein and healthy salads. I eat little to no packaged/gluten foods. I don't eat any dairy, rarely but that might be every 5-6 weeks a piece of cheese. It's not kept at our house. I have cut out much oil and try to stay on track ..I have found the cortisol was brutal when I was spinning on my bike 20-21 miles per day. That was about too hard on my knees and I believe my cortisol as well. (It was taking me about 70minutes) Now I limit myself to 40m per day(I haven't in 2 days, my knees were hurting bad) I do the weight training 3x per week and I can say if I follow this plan it's slow (which I'm told is best) but I am avaraging 5.5pounds per month loss! I like it this way cuz i have had occassions I've allowed bad food, in moderation. I have a rule at our house though ... no baking-ever. Too much of it around is dangerous to me and those I love.
Let me know if you try the Lcarnintine with raspberry keetones. I feel my success is better since adding it- I get them @vitaminworld.
Take care.

12-11-2012, 02:53 PM
I try them when then were on Dr oz as well went though 2 bottles and did'nt lose a lb.

12-12-2012, 04:03 AM
I try them when then were on Dr oz as well went though 2 bottles and did'nt lose a lb.

That's all you need to say that it was on Dr. Oz. I know how you feel, nothing he's recommended has ever worked for me. These days, I just avoid the hype.

12-15-2012, 11:46 AM
I just started with the rasp ketones and am waiting to see any results...but I am also on WW and have begun a 6 week walking program. So how do I really know they will work?

02-23-2013, 03:32 PM
Hi guys, I am new here and I just joined a few days ago.
I hope I am posting in the right spot!

I was wondering if anyone has had "success" with Raspberry ketones and if so which brand did you get?

Also is there anything I can do for my metabolism? I've started exercising and stuff, but I would like to take a supplement or something natural if possible that will help me get pumping!

Thanks guys!

02-25-2013, 08:02 AM
I have used raspberry ketones (the same ones dr. oz recommended) and saw absolutely no difference in either my energy levels or weight loss. Ditto with apple cider vinegar pills. I am hesitant to suggest this because I don't really think any diet pills are worth it, but capsaicin pills (red pepper) are supposed to have a good thermogenic effect. I tried them and found my stomach was way too sensitive for them, but YMMV.

02-25-2013, 08:10 AM
It depends what you mean by 'good', spicy foods have been shown to give your metabolism a slight boost but the difference really is pretty slight. You might burn an extra 10-20 calories/day by taking a capsaicin pill but in the overall scheme of things, that is not much :)

02-25-2013, 11:38 AM
and for what you pay for the pills, you're better off eating some raspberries and sprinkling some cayenne on your eggs.

02-26-2013, 08:30 AM
and for what you pay for the pills, you're better off eating some raspberries and sprinkling some cayenne on your eggs.

Most definitely. I have heard that even eating spicy foods and drinking very cold beverages is about the same as far as thermogenic weight loss as taking those pills. For me, it was definitely NOT worth it. 10-20 extra calories versus gross heartburn? No thanks.

02-26-2013, 10:32 AM
And actually, lemon juice is supposed to have a better effect than raspberry ketones but it is hard to sell overpriced lemon juice. So if you are tempted to try raspberry ketones, I'd say add a little lemon juice to your water.

03-07-2013, 04:21 PM
I don't see how taking in ketone supplements would aid in weight loss. Ketones are only used as an energy source when the tissues are starved for sugar (nocarb diets or when the tissues are unable to efficiently take up sugars) and fatty acids for the heart. If the preferred energy source is available, the ketones would just be broken down and excreted.
Also, the body will make ketones when needed...

03-07-2013, 08:36 PM
What I have heard is that most raspberry ketone supplements do not contain it. As to thermogenic effects, there are only 1-2 mouse studies, one showing an upregulation of adiponectin. While this would be positive, it needs to be assessed in humans. If you want a "supplement", I would rather suggest green tea. There, human clinical trials show an effect on abdominal fat loss.

06-02-2013, 04:02 AM
I was wondering about these too. I've had two different trainers tell me they work. But I was curious if anyone here had tried them.

06-02-2013, 07:29 AM
I am doing the Ideal Protein diet which gets your body to produce its own ketones. 2 weeks so far and I am really, really happy with the results, the programme, and I don't struggle with hunger or cravings.

06-02-2013, 07:43 AM
The produt on offer is a cheap chemical synthesis of the original ketones that were used in the mice study.

Raspberry Ketones are a desired ingredient in the scent industry and the cost of producing it in bulk is quite high. It is unlikely that most people can afford the real thing.

In other words - it's not worth the money!

06-02-2013, 09:20 AM
Dagmar - I'd say those trainers are full of it :) I merged this thread with another thread. There has never been a human study and as has been mentioned before, the rats in the study were living mostly off the ketones so to replicate it in a human, you'd have to eating a diet mostly of raspberry ketones then maybe it'd work.

06-14-2013, 03:29 AM
I've been using them. I think it's all placebo because the first day I had no appetite and was excited but I binged the second and third and said screw it because I never felt it again.

The caffiene in them suck too, no energy at all.
Not worth it!

04-29-2014, 01:41 PM
I went through 2 bottles and it just made me hungrier to the point where I felt I was never satisfied.

04-30-2014, 04:50 PM
I used them and they didn't do anything at all for me. i tried the Raspberry Ketones with Green Tea and the caffeine affected me negatively.

05-04-2014, 02:29 PM
Tried them...didn't have an effect. Another gimmick I'm afraid :(

05-13-2014, 02:03 PM
I tried them, and they did nothing. It was a waste of money.
