http://www.ncbi.nlm.nih.gov/pubmed/12097663 was a keto diet study without weight loss.
Lower triglycerides (-33%) and a trend to higher HDL (+11.5%; P = 0.066) which is fairly typical of keto diets studies.
Individual cholesterol responses :-
Protein percentage appeared to double. I wonder how much impact that had on HDL. Interesting that total and LDL remained neutral.
One thing I would find interesting is if they would provide similar nutrition intervention for the control group. Meaning, that they maintain their macronutrients but improved the quality of food. Because with keto, their diet was very high heavy in MUFA and PUFAs.
Oh and funded by Atkins, lol.
I hate when studies get clearly biased by the people paying for them. People walk away from it assuming all research is biased and can be dismissed. /rant
Personally, even if it was funded by atkins but was designed a bit better, I would be ok. And maybe I didn't see it, but if we are going to compare two diets, we should have similar nutritional standards. Having one group follow a very nutrient dense diet vs another with no control on the quality of food is a bit battling and makes me wonder how this would compare if it looked at keto vs vegan or even Mediterranean.
Exactly. It being funded by Atkins doesn't make it inherently biased. Setting the study up to potentially benefit the Atkins diet does.0 -

They didn't do that so we don't know, but it is routine for low carbohydrate diet studies to show reduced triglycerides and increased HDL.
Plenty of reading linked from http://www.ketotic.org/2013/09/the-ketogenic-diet-reverses-indicators.html0 -

So what difference exactly would that have made ? Did they fabricate the results to satisfy the funder ? Would government funding be free of potential bias ?
We've read the shirtless playbook already, if you have studies that show a ketogenic diet has a detrimental effect on blood lipids that would help answer the question then we would like to see them.
I did not post this study to compare anything but merely to answer the question about what a ketogenic diet does to blood lipids in the absence of weight loss. I would have equally happy if there was no control but then you would be harping on about it not being an RCT.0 -

First question - if you are going to make that argument that people can stay unbiased based on funding source, then I am fine with it. But then when it needs to be consistent since two weeks ago, you talked about a bias when there was no long term difference in diabetes treats. And its further no different than when you link tons of LCHF Kevin Hall studies that show benefit in real life application, but when I post the newest KH study, it's now considered half baked.
Second, lets not be obtuse here. Any diet that is highly focused on quality of food is going to be beneficial. Not arguing the fact that Keto produced these kinds of results. It's pretty well known that diets high in unsaturated fats helps reduce cholesterol levels.. why do you think the Mediterranean diet is so beneficial.
edit - one thing I would point out, that the average person who implements LCHF or Keto does not follow the parameters of this study. Most I have seen have diets very high in saturated fats (bullet proof coffee, heavy whipping creams, etc...).0 -
Morning Everyone,
I have browsed these comments with great interest. I have begun to use the Keto plan, not beause I want to lose weight, but because I am living with cancer. Carbohydrates of any sort are converted to glucose. Cancer thrives on glucose, so by starving them of it one hopes to limit their ability to proliferate. With limited carbs the body goes into ketosis and uses the fat for the energy it needs. SInce cancer cells cannot create energy from fat the theory is that they canot grow. It seems to be very useful for those with brain cancer, so why not other forms of cancer.
My difficulty in using MFP is setting my personal macros. There is no precision here. I have to chose the closest percentage rather than the actual percentge. When entering my foods. I find the system very unhelpful because so often I cannot enter the type of units accurately. I do not find having to say how many 1gram units I have used reliable. Butter goes AWOL doing this! I Want to enter the number of grams I have weighed out, not the number of servings! It is all very 'general'. Sometimes I find bizarre readings for things like cucumber. Trying to create a recipe from raw ingredients so that I can log the meal made from this recipe is also very limited. I cannot specify the units precisely. Neither can I specify servings according to those units. In tracking what I eat, there needs to be more precision at this stage.
Out of interest, Is there a way of importing a recipe directly from the internet? I'd value your tips as well as any exchange from those of you using Keto for health reasons, rather than weight loss.0 -

Hi Quavercat
I'm sorry to hear of your diagnosis but have been interested in the research regarding ketogenic diet in cancer, there is certainly a lot of promising trials and room for much more research so I wish you luck
In terms of using MFP to monitor your intake
1) I believe in the Premium version you can set macros by grams
2) the type of unit you can enter depends on the food entry you choose, there are many incorrect ones on MFP. I would recommend that you either
a) continue to look until you find an appropriate entry that does have grams entry (a lot do) but double check against pack and other nutritional calorie sites
b) enter your own foods and only use your recent / frequent list - you can add your name to the entry so that you are clear this is your personal entry
The recipe builder in the App is more responsive but you do have to search for each individual ingredient and select the correct one and repeat for each ingredient
Then weigh the final cooked dish and enter as either grams / 100g so that when you eat that recipe you can enter the exact number of grams you have used
Yes you can import by entering the recipe URL into the recipe builder - but again please do check ingredient by ingredient, checking nutritional guidelines and quantity
- again editing in the app is much easier - it is really only onerous the first time
I have to say that there are lots and lots of incorrect entries in the MFP database but with care you can use it to monitor your intake .. and really despite the glitches and issues I haven't yet found a better food entry system (though I keep looking)
Good luck0 -

Has any physician, particularly one that is actually a researcher in that area, actually recommended a ketogenic diet for your specific type of cancer?
Mice models have been showing that the idea of using ketogenic diets to cut out and limit glucose (which you can't truly do, you'll always have glucose in your body) just lead to fat adapted cancer cells.

Thanks for this. No I haven't discussed this with a physician yet - I am not aware that oncologists study nutrition!!!! I do have an appointment with the Nutrition Doctor soon, so I will be able to to get some further insights. Most of my knowledge and understanding comes from researching Pubmed articles.
This is a very useful website with well researched information: http://www.canceractive.com/cancer-active-page-link.aspx?n=3117 This is also a helpful resource: http://www.ketogenic-diet-resource.com/cancer-treatments.html
Some schools suggest that the Rainbow diet is more effective. Rest assured, I am not interested in ALTERNATIVES to cancer treatment, but ways of eating that help my body heal the immune system and keep it doing what it should do - find and destroy rogue cells. What is certain is that sugar feeds cancer cells, so even a basic low carb diet ought to help. However as a friend said to me recently, carbohydrates are still carbohydrates whether refined or not, and the body still uses them to produce glucose! What cancer cells go for next is the glutamine produced from protein digestion. So maintaining low levels of protein is also important. I guess this is why a lot of cancer dieticians recommend the vegetarian approach. It is a complicated field, and I suppose at the end of the day we must find the right balance for ourselves. How well we feel is a good guide. Currently I feel extremely well, better than ever!0 -

Your body runs on glucose. It will still create that even on a Keto diet.
BTW, you will find similar links for cancer prevents with Vegan/Vegetarians (high fiber/nutrient dense) and the Mediterranean Diet (high unsaturated fats, high fiber, nutrient dense). So in the end, if you going to do keto, do high fiber, high unsaturated fats as well.
At the end of the day, we all wish you the best.0 -

Cancer cells aren't one monolithic thing. They don't all have the same metabolic preferences.
The idea behind ketogenic diets for cancer came from brain cancer specifically because brain cells tend to need to use glucose, lactic acid, or ketones for all energy as nothing else can fit between the tight synaptic gaps. That idea doesn't extend to most other body cells, which means it wouldn't apply to cancer.
Preferring glucose followed by glutamine would probably describe 90% of your non-nervous system cells, healthy or otherwise.0 -

Exactly...I mean, from everything I've read and researched, pretty much anything you do to improve your diet and move away from the SAD is going to improve your health. I think comparing the SAD to anything is going to show that pretty much anything else is a miracle.0 -

And this is pretty much why you always hear things like: improve my blood panel, better skin (my personal fav), more energy, etc...
Well of course, when you stop treating your body like crap and filling it with nutrient dense foods, start exercising and losing weight, of course you will see all those improve... why... because obesity is the cause for a lot of health issues.

Great discussion everyone! If you want to explore further, the GreenMedInfo website is worth a look, as is The Truth About Cancer. These sites present the research on how sugar feeds cancer. Sure they are tending towards 'Alternative Medicine', but I think every approach can offer us tools in the control of our illness. I am convinced that holistic and integrative approaches are the way to go.
Now for something technical! I am tracking my macros which I have set to correspond to the Keto diet; it is taking a while to adjust my eating, but it os going ok. In checking totals on MFP I noticed that the automatic calculations are inevitably out by 1 sometimes above, sometimes below. Is this your experience too? It matters when you are trying to keep an eye on things!!!! My other question - are the carbs TOTAL or NET when they are recorded on MFP? My guess is that they are total, and so to get net I need to subtract fibre.0 -

Hodgkin's lymphoma survivor here…
when I did chemo and radiation they told me to eat carbs because they tend to be calorie dense and they want you to get as many calories in as possible, and it was never said that carbs should be avoided when one has cancer…
Is this something that your oncologist suggested?
sorry to hear about your diagnosis and hoping that you recover soon …

Ketosis is to hard to maintain its a crash diet to failure
Totally. I tried that diet on and off for a year. Lost a lot of weight but eating so much meat and fat eventually screwed with my mood. I was so snappy! Went off the diet and all the weight came back on but I was SO much happier. Restricted food diets work but not for life.0 -
I would substitute non-starchy vegetables for fruit, and you're good to go.0

Ketosis is to hard to maintain its a crash diet to failure
@exum235 I am sorry you failed at maintaining a state of ketosis. I agree it does take an informed effort. 99% I expect have no desire to live in a state of nutritional ketosis.
I think to be a 1%'er that has to be strong motivation to eat for better health based on my personal experience.
The first two weeks was very painful and I do not remember very much about them now when in Oct 2014 I went off of most all sugars and all forms of all grains. At the time I had lost down from to 250 to 230 by starving myself. Over the next six month eating <50 grams of carbs daily but pigging out a lot I lost another 30 pounds and lot of inches. After six months from the 2014 start I lost off signs of my 40 years of IBS. I lost most of my muscle and joint pain that had been with me for the past 40 years. My blood work and blood pressure number all moved in a positive direction. I lost most of my physical cravings after the first 2 weeks.
12 months after getting down to 200 pounds for the first time in 22 years I am still at 200 pounds and have stayed in a +/- 5 pound range.
My driving motivation was to manage my pain by diet so I could just say NO to Enbrel injections that the doctors were wanting me to start. In just 30 days (Nov 2014) of this WOE my subjective pain levels dropped from 7-8 to 2-3 range and are still managed by diet as of 15 Mar 2016.
An hour after eating breakfast my BG level was at 90 (usa) and ketone level was at 2.3.
exum235 I agree with your point as it applies to most people. If the KETO Way Of Eating works for one it is awesome. I do not promote it to most others because they are not motivated to last the first two weeks for the pay off.0 -

Correct. The general min carbs to be keto is just <50 grams of carbs daily. This does not insure weight loss but in my case after two weeks my physical cravings just started to fade quickly then the CI of CICO went down I guess. After I lost 50 pounds starting in 2014 I have been maintaining at 200 for 12 months now with other positive side effects.
Again keto is NOT a weight loss system because one can lose/maintain or gain weight eating in a state of Nutritional Ketosis. I have proved that but to gain I had to get my daily calories 3000+. I maintain at 2500 with a macro of around 5% carbs, 15% protein and 80% fats and as noted I have done so for the past year.
One can look like they have lost a lot of weight without the scales showing much weight loss with this Way Of Eat or at least that has been my experience for the past 18 months.
Most people can not cut carbs out so LCHF is not an option for most people in the real world. The Zero Carb folks are few and far between but I have not found it to be possible in a practical sense in my life.
Low carb (not keto) can be <150 grams of carbs daily.0 -
These diets work because they are in a calorie deficit, not because they cut out carbs. Primarily all these diets are high protein, high fat. The high protein helps with muscle maintenance. There just is no reason to deprive yourself of good foods. Put your body in a 20% calorie deficit, eat well and you will lose.0

It's chemistry!!!!!! (Glycerol can be metabolized to glyceraldehyde 3-phosphate and used in glycolysis or in gluconeogenesis). You have to eat enough fat for it to work though. An all protein diet won't do it.0 -

That's the how, though. I'm not doubting the body's ability to do so. It just seems like a bleak existence and I don't understand the motivation to completely eliminate carbs.0 -

The how is the fun part. I don't care why people do it. As long as they do it without hurting themselves, it's either for health (epilepsy, pain relief, intractable diabetes), weight loss when other diets haven't worked (even if it was because they can't behaviorally moderate their carb intake), or personal preference. I'm a moderate low carber, however I can easily imagine people preferring to eat a lot fewer carbs than I do and being happy about it, and people who do just fine on a few hundred grams of carbs a day, and have no blood sugar issues with it at all. With my family history, I should, at least, stay on the low end of carb consumption. In my family, skinny people who exercise get type 2 diabetes. With my blood sugar level drifting toward pre-diabetes, in spite of exercising every day and being at my ideal weight, I decided to cut carbs, and I'm now smack in the low healthy range, instead of the high healthy range. (And, yes, this was a doctor approved change).0
