In my opinion, Bob Atkins knew more about the theory and practice of the ketogenic diet, its benefits and limitations, including as applied to cancer patients, than anyone in the history of medicine. For him, the concept was hardly the musings of a PhD laboratory scientist, but the practical observations of a physician who treated thousands of patients over decades. And for cancer, the ketogenic diet just did not seem to work.
A study of 183 children in whom the diet was discontinued determined that the speed of the wean did not matter: children tapered over several weeks did just as well as those in whom the diet was stopped more slowly. Children in whom there was a good, but not complete seizure reduction with the diet (50-99% seizure reduction) were at highest risk for seizure worsening with the diet discontinuation . Should seizures worsen, many of these families elect to continue a low-carbohydrate diet versus new anticonvulsants . Some child neurologists opt to stop the diet over 4-6 weeks with close email contact.
Implementing the diet can present difficulties for caregivers and the patient due to the time commitment involved in measuring and planning meals. Since any unplanned eating can potentially break the nutritional balance required, some people find the discipline needed to maintain the diet challenging and unpleasant. Some people terminate the diet or switch to a less demanding diet, like the modified Atkins diet or the low-glycaemic index treatment diet, because they find the difficulties too great.
Artificial sweeteners such as saccharin (Sweet’N Low), aspartame (NutraSweet, Equal), and sucralose (Splenda) are quite popular among low-carb dieters. However, concerning new research indicates that artificial sweeteners have adverse metabolic effects and may work against your keto efforts by disrupting your gut microbiota and inducing insulin resistance and weight gain. (46, 47) If you want to use a non-caloric sweetener, I recommend either stevia or monk fruit sweetener.
Is the keto diet safe for someone with high cholesterol? Because keto is rich in fats, including saturated fat and cholesterol found naturally in animal-derived foods like eggs and meat, many people will experience an increase in cholesterol after beginning the keto diet. However, studies suggest the connection between the keto diet and cholesterol is actually positive.
If I was diagnosed with cancer or one of my relatives or friends were diagnosed, I would certainly put the ketogenic diet and fasting at the top of the list of potential treatments to investigate because I see a high potential for benefit and very little downside. You can’t say that about many cancer therapies. As we talked about earlier, the goal with cancer treatment is to find something that inhibits the growth of cancer cells but doesn’t damage healthy cells. Again, there just aren’t that many therapies out there that do that.
They need to make a lot of ATP, and quickly, to support their high requirements for energy. Adenosine triphosphate, also known as ATP, is a compound that provides energy to drive hundreds of thousands of biochemical processes in living cells. Found in all forms of life, ATP is often referred to as the chemical energy “currency” that powers metabolic activity.
Dave Feldman recently demonstrated that increasing net carb intake from 30 grams to 95 grams per day – (going from 4% of total calories to 13% of total calories) led to a significant drop in his LDL cholesterol level. Obviously, this level of carb intake isn't ketogenic; however, it is still moderately low carb. On the other hand, this will likely increase your blood sugar and insulin levels to some extent.
There is a lot I could respond to here, I’m a little surprised that you would include a study that feeds pregnant and lactating mice a diet (Teklad diet no. TD.96355) consisting of almost entirely hydrogenated vegetable shortening (Crisco), and also casein and corn oil, and calls it a “ketogenic diet.” On top of the fact that it’s a mice study. There is no evidence to show that there is any danger in pregnant and lactating women eating a (real) ketogenic diet. The only issue is that if a lactating woman switches from SAD to keto, “keto flu” may reduce her milk supply.

Tumors did not progress at all at all in the five patients that successfully completed the ketogenic trial. This is a positive outcome given the advanced stage of their cancer. Additionally, some of these patients experienced favorable changes in glucose, HDL:LDL ratio, triglycerides, and healthy levels of weight-loss. These findings further support the healthy impact a ketogenic diet may have on cancer.
Weight Loss – Part of the resurgence in interest in the ketogenic diet is due to the work of Dr. Atkins and his low-carb diet for weight loss. There is strong evidence to support the use of a ketogenic diet as a weight loss therapy.18 19 People following a low-carb diet tend to lose more weight in the first 3-6 months than those following a more traditional diet.20 Part of the benefit likely comes from the fact that ketogenic diets tend to suppress appetite and lead to a natural decrease in calorie intake.21 But even in studies where participants on a low carb diet ate the same number of calories per day as those on a lowfat diet, significant differences in weight loss were observed.22 This is likely due to the fact that ketosis relies on fat from the diet and body fat to produce ketones for energy.
These affect your brain and spine, as well as the nerves that link them together. Epilepsy is one, but others may be helped by a ketogenic diet as well, including Alzheimer’s disease, Parkinson’s disease, and sleep disorders. Scientists aren’t sure why, but it may be that the ketones your body makes when it breaks down fat for energy help protect your brain cells from damage.

Diets aren’t just for weight loss. What, how much, and even when we eat all affect the way our brains work. For people with epilepsy, diet can reduce the likelihood of seizures. Mackenzie Cervenka, a neurologist and director of the Adult Epilepsy Diet Center at Johns Hopkins Hospital, explains what the ketogenic diet is and how it can benefit people with epilepsy.
The total-to-HDL cholesterol ratio is found by dividing your total cholesterol level by your HDL-C, and it is essentially the same thing as an LDL-to-HDL cholesterol ratio since most non-HDL cholesterol is LDL cholesterol . The researchers of the 2003 meta-analysis used this ratio because it is a better cardiovascular risk predictor than total cholesterol levels .
The bottom line here is that the ketogenic diet is a powerful metabolic tool for treating a wide range of illnesses. It is not a fad diet, and if it is implemented correctly, it corrects metabolic function at the cellular level. This website discusses in detail the mechanisms of a ketogenic diet, including side effects, benefits and other information.
For patients who benefit, half achieve a seizure reduction within five days (if the diet starts with an initial fast of one to two days), three-quarters achieve a reduction within two weeks, and 90% achieve a reduction within 23 days. If the diet does not begin with a fast, the time for half of the patients to achieve an improvement is longer (two weeks), but the long-term seizure reduction rates are unaffected. Parents are encouraged to persist with the diet for at least three months before any final consideration is made regarding efficacy.
A side benefit of the diet is that many parents say their children are more alert and make more progress when on the diet, even if seizures continue. If the diet seems to be helping, doctors will usually prescribe it for about two years. Then, they may suggest that parents slowly begin including regular food in the child’s diet to see if the seizures can still be controlled, even with a normal diet.
Ketogenesis has existed as long as humans have. If you eat a very low amount of carbohydrates, you starve your brain of glucose, its main fuel source. Your body still needs fuel to function, so it taps into your reserve of ketones, which are compounds the liver creates from fat when blood insulin is low. This process is known as ketosis: It’s like when a hybrid car runs out of gas and reverts to pure electricity.
“For me, the focus is on optimizing nutrition, and on nutritional interventions as part of the therapy for chronic diseases,” he said. “Depriving the body of access to any major macronutrient changes metabolism and invariably has a negative impact on health. The best nutritional intervention for weight loss is a caloric-restricted, portion-controlled, well-balanced meal plan.”
The ketogenic diet has been shown to produce beneficial metabolic changes in the short-term. Along with weight loss, health parameters associated with carrying excess weight have improved, such as insulin resistance, high blood pressure, and elevated cholesterol and triglycerides. [2,7] There is also growing interest in the use of low-carbohydrate diets, including the ketogenic diet, for type 2 diabetes. Several theories exist as to why the ketogenic diet promotes weight loss, though they have not been consistently shown in research: [2,8,9]
My uric acid is way high at 7.6 with last test at 3.5 and this is obviously a big deal. I am putting strong efforts into fixing this and the bubbles in my urine likely uric acid although previous testing of 24 hour urine showed protein in the urine. No doctor will see my as a kidney patient. I am back to juicing and going low protein since I sense I have kidney issues with kidney pains and too much urination. Maybe it is all just the mold?
In his books and in his office working with his own patients, Dr. Atkins warned that to reap the benefits of his diet, one must reach and stay in a state of ketosis, much like the traditional Eskimos. Even a slight deviation from the diet, some ill-advised cheating with a cookie or candy, could stop ketosis in its tracks, and with it, the value of the diet.
Jimmy Moore: Yeah, just be in control of your own health. That’s the major theme that I’ve tried to push the last couple years. I’m tired of people advocating their responsibility for their own health to a dietitian, to a doctor, there’s just way too many resources. This YouTube channel you’re watching right now is just unbelievable for content, my podcasts, books, there’s all sorts of information that’s out there. A lot of it for free, take advantage of that because I think the more you know the more empowered you can be and whether doctors and dietitians and all these medical professionals like it or not, the empowered patient is the future of healthcare. I think if we’re going to really make a difference in our own lives, and then collectively as a culture in our health, it has to start with the individual caring again.
The medical community has known about cancer cell’s preference for glucose for quite some time. In fact, one of the ways they get an image of a tumor is essentially by injecting a glucose-based “dye” into the body and using some sort of machine to see that “dye.” The area that lights up the most when taking the image is where the cancer tumor is – that’s because of the cancer cell’s overwhelming desire for glucose.
Physicians of ancient Greece treated diseases, including epilepsy, by altering their patients' diet. An early treatise in the Hippocratic Corpus, On the Sacred Disease, covers the disease; it dates from c. 400 BC. Its author argued against the prevailing view that epilepsy was supernatural in origin and cure, and proposed that dietary therapy had a rational and physical basis.[Note 3] In the same collection, the author of Epidemics describes the case of a man whose epilepsy is cured as quickly as it had appeared, through complete abstinence of food and drink.[Note 4] The royal physician Erasistratus declared, "One inclining to epilepsy should be made to fast without mercy and be put on short rations."[Note 5] Galen believed an "attenuating diet"[Note 6] might afford a cure in mild cases and be helpful in others.
Another hypothesis regarding the function of the KD is related to changes in neuronal metabolism, mitochondrial function and energy reserve, and the environment. In normal conditions, the usual substrate for the neurons is glucose. To facilitate its diffusion through the brain-blood barrier, glucose transports are present in the brain capillary endothelial layer (Greene et al., 2003). The glucose metabolism produces the rapidly available energy that is necessary for seizure activity. Therefore, in patients on the KD, the blood glucose energy levels are low, and the brain begins to use KB for energy. This anaerobic metabolism slows the energy availability, which reduces seizures. The anticonvulsant propriety of a decrease in glucose metabolism has been shown in experimental models in which the administration of 2-Deoxy-D-glucose elevates the seizure threshold (Garriga-Canut et al., 2006). The anticonvulsant effect of the KD can be quickly reversed after glucose infusion (Huttenlocher, 1976). Based on these data, we can postulate the influences not only of the KB, as discussed above, but also the reduction in glucose levels as a mechanism of action of the KD.
The Modified Atkins diet and modified ketogenic diet (sometimes called 'modified ketogenic therapy') use a high proportion of fats and a strict control of carbohydrates. These are often considered more flexible than the classical or MCT ketogenic diets, as more protein can be eaten, and approximate portion sizes may be used in place of weighed recipes.
You can get cholesterol from eating animal foods like eggs, cheese, meat, and dairy but your body can also produce its own. An average 150 lb weighing male can synthesize 1000 mg of cholesterol a day. One single egg has 200 mg of cholesterol. The typical US dietary intake of cholesterol is about 307 mg[iv]. In that case, about 75% of your body’s cholesterol gets produced by the body internally and 25% gets ingested externally[v].
Hello, following a Keto diet with IF but cholesterol ratios not proper. Diet fats come mainly from olive oil, avocado oil, once a week beef, no butter, bacon etc. Had to go back on statins. Goal is stay away from drugs. Is there a doctor/clinic in the Boston area that you can recommend that understands/tests what you explain in this article? Please advise.
I’ve been Keto for over a year now. I’ve lost 60 lbs. I’m off Metformin for type 2 diabetic and my LDL has improved significantly. In my experience, Keto will show some quick results in some but for others it will take longer. It depends on how long you’ve been on the standard American diet. It will take time for your body to fix “self-heal”. Not everyone will have the same results in the same amount of time.
Ketogenic diets represent a far more effective strategy for managing type 2 diabetes than the American Diabetes Association’s high-carb, low-fat dietary guidelines. Unlike the ADA’s guidelines, a ketogenic diet significantly reduces blood sugar, hemoglobin A1c levels, waist circumference, and triglycerides in diabetic individuals. (13) Most importantly, research indicates that the diet is sustainable for diabetic patients and that the beneficial changes can be maintained over the long term. (14)
Just because your favorite celebrity endorses a program doesn’t mean you should try it. No plan works for everyone, and that goes double for ketogenic diets. As I mentioned before, while they can initially create fat loss, ketogenic diets were never designed to help you lose weight. Especially if you’re eating too many calories—very possible on a high-fat ketogenic diet—you can be in ketosis and not lose weight (or even gain weight). Likewise, many people lose weight just fine without ever "going keto."
But no fear, there’s always a new miracle around the corner, and in 1998 the newspaper reporters and TV newscasters, having effortlessly drifted away from interferon and interleukin-2 and the bone marrow transplant craze, were all in a tizzy over the newest “final” solution to cancer, anti-angiogenesis, based on the pioneering work of the late Dr. Judah Folkman of Harvard. Dr. Folkman had spent decades studying the process of angiogenesis in cancer tissues, the formation of new blood vessels that allow tumors to grow quickly and invade through normal tissues and organs with deadly effect.
