How low carb diets feed cancer

How low carb diets feed cancer

One of the biggest fads today is the ketogenic diets or low-carb diets.

Everybody blames sugar for all of their problems.

And then you have the claims that “sugar feeds cancer.”

So a lot of people start this low-carb diet for cancer treatment.

In their efforts to not feed cancer sugar, people embark on these very low-carb diets.

However, when you are on a low-carb diet, your body will create sugar.

Your body must have sugar to feed the blood cells and feed the brain.

Both the brain and the blood require a constant sugar level to survive.

In fact, they cannot survive without it — they must have sugar.

So, your body makes sugar even if you don’t eat it.

And your body also will make what are called ketones, or ketone bodies.

Ketone bodies are fuel.

Ketone bodies can be fantastic fuel.

The body can easily get them in from the coconut oil in your diet.

But that’s not the only thing the body uses to make ketone bodies.

And this study shows the negative impact there is when the body makes ketones instead of eating them.

The process the body uses to make ketones feeds cancer.

I want you to understand this because this is so important.

Eating fats like coconut oil or MCT Oil by themselves will increase your ketones and are not harmful.

On the other hand, if you eat a low-carb diet, and force your body to make its own ketones, it’s very bad.

It can be very harmful, and that is what this study really talks about.

In this carefully crafted study, they perform their research on breast cancer cells.

But the same type of cancer affects men as prostate cancer.

And the effects can probably be generalized for any cancer.

They found that the process of producing your OWN ketones:

increases the mitochondrial mass and growth of adjacent breast cancer cells….and effectively promote tumor growth, without a significant increase in tumor angiogenesis.

This statement is important because it shows that if you are on a ketogenic diet, the process of generating your own ketones promotes cancer growth.

And that this cancer growth does not require additional blood vessels.

Ketones are so effective at feeding cancer that the cancer tumor can grow without having to gain additional blood vessels.

This is a striking finding.

And it really should give anybody on a ketogenic diet or a low-carb diet something to think about.

Worse, it’s not just feeding the growth of the tumor,

ketone body production and re-utilization drive tumor progression and metastasis.

The fact is that a low-carb diet is a high-stress diet.

The body is designed to get most of its fuel from carbohydrates in the form of sugar or starch.

Now, the body will store fuel as fat when it has extra fuel.

And then the body will use its fat to protect against starvation.

It’s very difficult to lose fat because the body wants to hold onto it in case it needs it later.

It put a lot of effort into creating that fat store — the body isn’t going to risk losing it easily.

So, it’s important that if you do want to lose fat and regain your health, you should not to go on to a low-carb or ketogenic diet.

There are many problems with this type of diet.

And now we know that cancer is yet another problem with low-carb diets.

Ketone body utilization drives tumor growth and metastasis 


  1. You have got to be kidding me. Even as a layperson, I’ve been doing this kind of research for over 15 years and I know scores of people anecdotally, and I’ve read and watched multiple accounts online, not to mention have read countless books on the topic and attend regular conferences on natural alternatives to cancer where I’ve been exposed to people who have personal experience with this.

    Low carb does absolutely not feed cancer. I wonder who you’re working for, and why in the hell you would push this narrative that would actually harm more people than help them.

    Maybe do your own research and stop relying on your paycheck to dictate your narrative. Unbelievable.

    • He is quoting major research he found-did you not notice that in your keto rage?? He is a long time (26 years) journalist in medical research-and found some interestng research to report.Maybe you need to offer or do some of your own research to justify your comment.

  2. I resent the statement that low-carb and ketogenic diets are “fads.” Just because the obesity epidemic has grown worldwide, and these people are NOT following a low-carb diet, does not make these diets fads. Sometimes the road not taken is the right road. I remember the days when lots of doctors claimed that smoking was actually good for you. I agree with the last commenter: this article is not only disproved by numerous double-blind, randomized studies, following this article’s advice could prove deadly to a vast section of the population.

  3. You fail to mention in the article that, in this study, researchers had to genetically engineer cells to cause them to produce and reutilize ketone bodies. They even named these genetically engineered cells “ketogenic fibroblasts”. From the study itself:
    “ we generated hTERT-immortalized fibroblasts overexpressing the rate-limiting enzymes that promote ketone body production, namely BDH1 and HMGCS2. Similarly, we generated MDA-MB-231 human breast cancer cells overexpressing the key enzyme(s) that allow ketone body re-utilization, OXCT1/2 and ACAT1/2.”

    Surprised that, with all the writing you do, you can’t bother to actually read.

    Next time you think you should report on something, do everyone a favor; don’t.

  4. I’ve read the article, also researcher in oncology. This publication describes a specific cell population, fibroblasts, and their ability to promote growth of mutant breast cancer cells, mda-mb-231. Important to know the implications of these cell types and the stage of scientific inquiry. The really nice co-culture in vitro experiment comes to a recommendation that inhibitors for a particular ketogenic pathways in cancer supporting fibroblast merit investigation, maybe even one day a clinical investigstion. Totally agree with this.

    With this article, you’re asserting a conclusion not supported by this really nice primary work.
