First of all, myeloma patients, even when diagnosed with an aggressive form, often linger for years before the disease advances. I would never have included such a two-year survivor in One Man Alone, or in any other book I have written or plan to write – unless, possibly, there has been documented significant regression of disease, not apparent in this case. I do include a case of multiple myeloma treated by Dr. Kelley in my monograph, a woman diagnosed with extensive cancer throughout her skeleton with evidence of multiple fractures.
So sugar feeds the cancer cells- you dont have to go full keto just stop eating sugar? I keep reading meat causes cancer and a vegan diet is best! When you cut out sugar and all grains you end up eating dairy and meat, with nuts for a treat. Friut is off the list, honey and some root veg like potatos so if you cut down on meat what the feck are we left with? you can only eat so many eggs,avocados and spinach. I also am yet to find a keto dessert I like, coconut flour and stevia dosent make a cake.
When in the hospital, glucose levels are checked several times daily and the patient is monitored for signs of symptomatic ketosis (which can be treated with a small quantity of orange juice). Lack of energy and lethargy are common, but disappear within two weeks. The parents attend classes over the first three full days, which cover nutrition, managing the diet, preparing meals, avoiding sugar, and handling illness. The level of parental education and commitment required is higher than with medication.
So on the surface, Dr. Seyfried’s argument that cancer is primarily a metabolic disease (an argument I’ll look at in more depth shortly) is well within the bounds of current oncologic science. Indeed, a few years ago it was all the rage, and I remember attending several sessions and lectures on the Warburg effect and cancer at the AACR meetings three or four years ago, although, oddly enough, I don’t recall as many the last couple of years. In any event, if that’s all I looked at, I probably would have shrugged my shoulders and moved on, as in, “Nothing to see here.” But there are quite a few red flags. The first red flag is a claim that a ketogenic diet can treat cancer better than chemotherapy. The second, even bigger, red flag is on Dr. Seyfried’s Boston College web page:
I recall so well, this time sitting in my mid-Manhattan office, reading that famous May 3, 1998 front page lead New York Times article (in the upper left of the page reserved for wars, revolutions, and, yes, miracles) by reporter Gina Kolata, announcing Folkman’s preliminary findings to the world, extolling anti-angiogenesis in a tone that one more skeptical writer, Jack Breibart, described as “breathless.”
Hi Mel, Assuming that your ranch dressing doesn’t have sugar added, you don’t need to worry too much about limiting it, but within reason. This is my homemade ranch dressing recipe, which has 0.9g net carbs per 2-tbsp serving. It would be hard to find a store bought one with much less than that, even though some round anything less than 1g down to 0g, which isn’t truly accurate. Also, keep in mind that if weight loss is your goal, some people find that too much dairy can cause a stall. Finally, make sure you aren’t using all your “available” carbs on ranch dressing – have it with some low carb veggies!
Importantly, cholesterol doesn’t travel around your bloodstream on its own. As a hydrophobic (water-repelling) substance, it must be packaged within lipoproteins to move around the bloodstream. So that means when we talk about blood cholesterol levels, we’re referring to the amount of cholesterol contained in different lipoprotein particles. In addition to cholesterol, these lipoprotein particles also contain special proteins called apolipoproteins, triglycerides and other compounds.

Because some cancer cells are inefficient in processing ketone bodies for energy, the ketogenic diet has also been suggested as a treatment for cancer. A 2018 review looked at the evidence from preclinical and clinical studies of ketogenic diets in cancer therapy. The clinical studies in humans are typically very small, with some providing weak evidence for anti-tumour effect, particularly for glioblastoma, but in other cancers and studies, no anti-tumour effect was seen. Taken together, results from preclinical studies, albeit sometimes contradictory, tend to support an anti-tumor effect rather than a pro-tumor effect of the KD for most solid cancers.
In contrast to the safe application of KDs reported in various cancer models, our research group recently reported that mice bearing renal cell carcinoma xenografts and with signs of Stauffer’s syndrome experienced dramatic weight loss and liver dysfunction when treated with a KD . Another study investigating the effect of long-term KD treatment on kidney cancer described a pro-tumor effect of the KD in a rat model of tuberous sclerosis complex . Most concerning is the observation that, in a mouse model of BRAF V600E-positive melanoma, tumor growth was significantly increased under the KD . Moreover, the study also demonstrated that the ketone body acetoacetate stimulated the oncogenic signaling of the BRAF pathway. In contrast, the KD had no effect on the progression of NRAS Q61K-positive or wild-type melanoma xenografts . Notwithstanding these observations, in a feasibility trial involving a limited number of patients with advanced malignancies, a patient with BRAF V600E-positive/BRAF-inhibitor resistant melanoma seemed to benefit from the KD .
In a model of PD, neurons cultured from the developing mesencephalon, the site of the future substantia nigra, are susceptible to injury and death from the application of 1-methyl-4-phenylpyridinium (MPP+), which inhibits mitochondrial energy production. Adding one of the ketone bodies, β-hydroxybutyrate, rescues these cells from death and reduction in neurite outgrowth . In an in vivo model, mice treated with β-hydroxybutyrate via continuous subcutaneous infusion were relatively protected from the dopaminergic degeneration induced by injection of MPTP, an MPP+ precursor, apparently by enhancing oxidative phosphorylation and the production of ATP .
Fanatic? Someone with T2D, a disease usually claimed to be progressive and a never ending stream of problems and medications, was REVERSED. That’s something to shout from the rooftops. The drop in medication use alone, but the big pharma companies would prefer that people’s stories of reversing (well, putting it into remission) T2D get called fanatical instead of insightful.
Can your body handle higher amounts of dietary fat? (To make this process easier, I recommend my patients gradually increase their fat intake. Your digestive enzymes need time to ramp up to be able to handle the higher fat content in your digestive tract, or it can cause unpleasant gas, bloating, and diarrhea.) Remember: If the thought of eating higher-fat foods like steak or avocado doesn’t appeal to you, keto probably isn't for you.
The most common side effects are constipation that can be supported with some dietary adjustments and laxatives. Other side effects that may occur that are relatively minor and transient include: kidney stones, low sugars, nausea, vomiting, diarrhea, sleepiness. There are some reports of longer term side effects that may include higher cholesterol, reduced bone health, kidney stones, slower linear growth velocity and abnormal heart rhythm.
Similarly, in a 2015 study, mice receiving a combination of hyperbaric oxygen and dietary ketone supplementation showed a clear reduction in tumor growth rate and metastasis.20 Also, these mice lived twice as long as control animals. Based on these results, the study authors state that further investigation into the effectiveness of this combination therapy as a potential treatment for late-stage metastatic cancers is urgently required.
In both patients, levels of blood glucose decreased to low/normal levels and ketones increased by 20 to 30 times within seven days of starting the ketogenic diet. Results from scans indicated that there was a 21.8% decrease in glucose uptake at the tumor sites in both subjects. Lower glucose uptake is a strong indicator that a tumor is shrinking in size.
I knew Bob quite well, and considered him a friend. We first met when I interviewed him for a nutrition story during my journalism days, and later on while I was a medical student, we kept in close contact. During my freshman year at Cornell Medical School – from which Bob had received his own medical degree – I arranged for him to speak as part of a lecture series I had set up on alternative approaches to disease.
