The length of time that arteries are exposed to high levels of LDL particles is believed to play a significant role in the development of atherosclerosis. Smaller LDL particles typically spend more time in the bloodstream than larger particles do, making them easier targets for oxidation and incorporation into plaque. Moreover, people who have a lot of small LDL particles tend to have low HDL cholesterol and elevated triglycerides – all of which are markers of insulin resistance and reflect increased cardiovascular disease risk.
There are actually two kinds of LDL particles (typically called “patterns”). Pattern A LDL is large, “fluffy,” and buoyant. Pattern B LDL is small and dense. Pattern B LDL proteins tend to get stuck in the nooks and crannies of blood vessels (arteries, especially). These are the primary culprit for “clogged arteries.” Pattern A LDL proteins are too big to get stuck in blood vessels.
Any recommendations on cookbooks? I just purchased Simply Keto and the author uses what seems an abundance of processed meats which have highly toxic cancer causing sodium. Also, the sweeteners suggested rather then sugar are also highly toxic cancer causing…and so on. I am trying to cancel my order so I can research more on recipes, using foods that truly are healthy and not causing cancer in itself, losing weight is not my priority and seems these cookbooks are more focused on losing weight not fighting cancer. The list of foods provided could not be complete, so if you are going to guide people to Keto lifestyle (I hate using the word “diet”) please provide more information such as those in the know and can trust recipes and guidance with complete list of foods and so on. Thank you in advance.
You will need to learn how to prepare meals differently, which takes time and work. There also may be some difficulty adapting to the new meals. However, with creative meal planning and sensitivity to your difficulties, along with support from your ketogenic diet team some of these obstacles can be overcome. In time you will adapt with the significant changes and meal preparation and meal time will become easier. Many families cope well with the challenges and would agree that the hard work is worth it if the diet significantly reduces the seizures.
Let’s go back to the research assessing how the low-carb, high-fat diets such as the ketogenic diet affect your LDL levels. In the meta-analysis by Bueno et al., low-carb diets were shown to increase HDL twice as much as low-fat diets after randomized controlled interventions. It also showed that there was a small increase in LDL-C in low-carb subjects compared to low-fat diet subjects who experienced no increase.
Hi, I’m still a bit skeptical, I have seen some of my friends do the keto diet, and have had good results. Though I am still not sure about the idea of the fats being eaten. They say they eat meat with the fat and must do so, is this correct? Also isn’t this not good for the body especially for the kidneys? Second, can a diabetic do this diet? There are many questions running through my head.
Apoptosis Induction. Studies show that dietary energy restriction enhances phosphorylation of adenosine monophosphate kinase (AMPK), which has been found to induce apoptosis in glycolytic-dependent brain cells and protect normal brain cells from death. One way to naturally restrict energy consumption is with a keto diet because most keto dieters spontaneously eat fewer calories than they do when they are on a higher carb diet. Altogether, this may explain why most of the research on keto and cancer has shown the keto diet to be effective in the treatment of brain tumors (glioblastomas and gliomas).
About 59% of participants completed the 12-month trial: 33 in the low-carb group and 36 in the low-fat group. Both groups lost similar amount of body weight and body fat. The subjects who participated in the low-fat intervention experienced an average increase in HDL cholesterol of 0.07 mmol/L from 1.36 mmol/L to 1.43 mmol/L. [12] This represents a 4.9% increase.
There are indications that the way the ketogenic diet produces “ketones”, or the “ketogenic effect”, is being studied in order to produce pharmaceutical products (drugs or vaccines) that can mimic the same effect. With years of experience now documented in using the ketogenic diet with children suffering from seizures, one of the most common complaints is that the diet is difficult to adhere to, as the child has to abstain from refined carbohydrates and typical childhood sweets such as cakes and candies.  The reasoning is that a drug would make life more bearable instead of following such a strict diet.

I have great respect for Harvard Medical School. I notice that they support their readers posting comments and I am most appreciative of the article and all the many thoughtful comments by the readers. The readers seem to have the most expertise here and I hope that the doctor who wrote the article will think long and hard about the comments by readers. After 35 years of clinical practice in mental health, I notice that all issues of emotion involve medical issues, nutrition, and the gut bacteria. I would say that these issues and all of the executive brain functions seem to improve with ketogenic principles. For those that apply it in a flexible and smart manner, it appears to improve every area of their lives. I strongly encourage the author of the article to take one class via The Institute for Functional Medicine. If he is open to more learning he can take more classes and get certified. I’m sure a fine doctor, he will be an even better doctor and personally healthier, if he gets more training. Are we all open to new learning(especially us healthcare providers)?
Clearly, ketogenic diets are not ready for prime time as a treatment for cancer, either alone or in combination with conventional therapy. Unfortunately, that hasn’t stopped it from being touted by all manner of alternative cancer practitioners (i.e., quacks) and others as a cancer cure that “they” don’t want you to know about or saying things like, “…it’s nothing short of medical malpractice and negligence to fail to integrate this type of dietary strategy into a patient’s cancer treatment plan,” as Joe Mercola did. Dr. Seyfried himself has contributed to the hyperbole quite a bit as well. For example:
“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.”

Leanne: Billion. Okay, let’s talk a little bit about Staten, I can’t remember what book it was but they were saying that cholesterol is really important for brain health. You mentioned that too, the cholesterol uses the nutrient and moves it up to your brain, it’s really important. What I was reading is that as we age our cholesterol actually increases slightly to help with that aging process. You often meet people that are in their 40s, 50s, I know a lot of people in my family are now on Staten because their cholesterol is increasing. I always say, “Maybe that’s your body’s way of protecting yourself against aging.”
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.
“It may be difficult for keto-dieters to meet their energy and protein needs, and the diet may cause long-term issues, including kidney damage, higher cholesterol levels, unintentional weight loss, bone loss, and certain vitamin and mineral deficiencies,” the article says. They say a more moderated approach to the diet may be advised, and cite that reducing refined carbohydrates and increasing the amount of healthy fats consumed can be beneficial to one’s overall health.
The American Academy of Neurology and the Child Neurology Society recommend adrenocorticotropic hormone (ACTH) as the first line of therapy for infantile spasms. The goals for this medication are to completely stop the infantile spasms and improve the abnormal EEG. In some cases, pediatric neurologists prescribe the seizure medication Sabril® (vigabatrin), especially for patients with tuberous sclerosis. Both drugs work well, but your child's doctor will talk with you about which medicine may be the better choice for your child.
Once the body is adapted to ketosis, constipation and/or diarrhea are the most commonly reported side effects along with increased urination. Continuing to keep your mineral intake high and ensuring adequate water and fiber intake will help to counter these effects. People in ketosis may also notice a sweet or fruity odor on their breath, which is the result of increased production of the ketone acetone, which is a very volatile compound that is eliminated mainly through respiration in the lungs. 50
Hi I’m new to Keto. I have been reading about it, and understanding what to eat and what not to eat. My problem is I’m not sure if I’m doing it correctly. I’m constantly hungry whereas information reads that I will never be hungry. I use fats as required along with topping up with vegetables in my meals yet this does not fill me up. I haven’t experienced the Keto flu and I’ve even put on weight! I have been doing this for about 3 weeks now. Any ideas where I am going wrong.

Duchess was diagnosed with cancer in her right anal gland. When the cancer was removed it had spread to her left anal gland and was attached to her bowels. She was given 3 months to live. Since then I have had 2 vets check her glands and have had complete physical. She has a clean bill of health. I am so grateful to you. We are going to start on a maintenance program. I tell everyone how she has done. Thanks
There are other studies, but little or nothing in the way of randomized clinical trials. For instance, a recent retrospective study of 53 patients, of whom only six followed a ketogenic diet while being treated for GBM, concluded that the diet was safe, but no suggestion of efficacy was noted. More recently, a German group examined the effect of a ketogenic diet on 16 patients with advanced cancer of various types who had exhausted all therapeutic options. The treatment didn’t result in any serious side effects, although subjects found it very difficult to maintain the diet, particularly in the context of family life. Only five were able to complete the three month treatment period, and it was reported that these five didn’t have progression while on the diet. Of the remaining 11, two died early, one was unable to tolerate the diet and dropped out very quickly, two dropped out for personal reasons, one couldn’t continue the diet for more than a month and three had disease progression within less than 2 months of starting the diet and one dropped out to resume chemotherapy. As a whole, this study was well-nigh uninterpretable due to the different kinds of cancer, other than to conclude that less than 50% of patients with advanced cancer could adhere to the diet, and that those who could generally had no significant side effects. Of course, it’s unclear whether the diet helped the five who could adhere to it or whether those who adhered to it could do so because they had more indolent, less aggressive disease.
I had the same doubt about coconut oil, I read someone recommending that the first thing to do would be dropping bulletproof coffee and changing to olive oil. Do you think is that valid? My father also has high cholesterol and had a heart attack, though he also had a smoking/drinking record. I never drink/smoke and always exercise, so I hope that compensates, since all the other markers seem to be normal..,though I'm worried and thought if I should just eat more fiber and come back to a Paleo diet including some fruit ( the same guy that recommended the olive oil instead of coconut said that, I don't know if it's valid)
Several laboratory abnormalities have been reported in children on the ketogenic diet, although none has been found to have clinical significance. Patients on the ketogenic diet are in a chronic acidotic state, putting them at risk for osteopenia. Some studies have shown a progressive loss of bone mineral content, resulting in osteopenia and osteoporosis; this loss occurred with ketogenic diet treatment despite improved serum vitamin D concentrations.
It starts with limiting carbohydrate intake to just 20–30 net grams per day. “Net carbs” describes the amount of carbs remaining once dietary fiber is taken into account. Because fiber is indigestible once consumed, simply don’t count grams of fiber toward their daily carb allotment. So that means subtracting grams of fiber from total carb games, to give you the total net carbs.

Yes and there is also 1000s studies that are paid by the meat industry to say that meat is good. What u say is right BUT the meat industry is really messed up too. Super intensive production of really low quality beef is killing us and the planet. Watch cowspiracy/ and documentaries of the sort and then tell m the balk of the problem is not here.. or at least as big as sugar corporations

Societies have lived off whole meats, vegetables, and fruit for our entire existence with very little known disease; including multiple cultures that are essentially carnivores. Diseases increased exponentially in the western world once sugar was added to everything and the junk food boom took place. Our bread is even so processed now that it has the same effect on your blood sugar as eating a tablespoon of sugar. (Yes, the average age some lives is greater today than it was before the sugar boom but that is because infant mortality has decreased 200+% in the same timespan and is now in the single digits. The lifespan of someone who made it to adulthood was the same as it is now. Even Socrates lived to be 77 without modern medicine{‘throw drugs at everything”} before being executed.

Typically known as the “bad cholesterol” to its healthy counterpart HDL cholesterol, increased levels of LDL cholesterol are associated with an increased risk of cardiovascular diseases (CVD). [14] Some studies show a strong correlation between LDL cholesterol and the risk of cardiovascular diseases in both men and women. [15] Evidence also suggests that decreasing blood levels of LDL-C reduces the risk of CVD. [16]

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.

Jimmy Moore: 300 is the normal. Yes. That’s 100 points higher than authorities today would say is “normal”. Yet if they put them on cholesterol lowering medication, do you know they would have been at greater risk for heart disease if they took that pill then they’re total cholesterol being 300. I think it all circles back around to it’s not about the cholesterol people, it really is about the inflammation.

Like any trendy diet worth its balanced portion of salt, the keto diet is said to hold transformative powers. Proponents say it can help people lose weight, improve mood and experience fewer epileptic seizures. For the most part, the science seems to back these claims up — though, to be sure, it's not completely understood how exactly the keto diet affects mood (particularly depression), despite anecdotal evidence the diet might lead to clearer thinking and fewer symptoms of depression.
Multiple mechanisms of action may explain why the modification of the KD can be effective even without ketosis. Importantly, the KD systemic action can have a broad spectrum of effects that may be beneficial in the treatment of different types of epilepsy and associated comorbidities such as cognition impairment, psychiatric disturbance, and sudden unexplained death.
Protein consumption can also stimulate a little protein present in the body called mTOR (short for mammalian target of rapamycin) which helps regulate cell growth, proliferation, survival, and protein synthesis (among other things). Something as simple as a big juicy steak will cause our body to upregulate (stimulate the increase of) mTOR — and when this happens, the cells can “forget” to do some very important things (like controlling and preventing cancer growth).
On a “strict” (standard) keto diet, fats typically provides about 70 percent to 80 percent of total daily calories, protein about 15 percent to 20 percent, and carbohydrates just around 5 percent. However, a more “moderate” approach to the keto diet is also a good option for many people that can allow for an easier transition into very low-carb eating and more flexibility (more on these types of plans below).
A ketogenic diet also has been shown to improve blood sugar control for patients with type 2 diabetes, at least in the short term. There is even more controversy when we consider the effect on cholesterol levels. A few studies show some patients have increase in cholesterol levels in the beginning, only to see cholesterol fall a few months later. However, there is no long-term research analyzing its effects over time on diabetes and high cholesterol.
For most people, a ketogenic diet leads to improvements in cholesterol, but there are sometimes transient rises in cholesterol levels during weight loss. During rapid weight loss, cholesterol that you had stored in your adipose tissue (ie, body fat) is mobilized, which will artificially raise serum LDL as long as the weight loss continues. To avoid being misled by this, the best time to check blood lipids is a couple of months after weight loss ceases. Total cholesterol includes HDL (the so called ‘good cholesterol’), which usually goes up 10-15% on a ketogenic diet. That said, some people have high calculated LDL cholesterol values even after weight loss stops. If this occurs, you should discuss further diagnostic tests with your doctor. Current research is looking at LDL cholesterol as a mix of different particle sizes, where the small ones are dangerous and the larger ones are not. With a well-formulated ketogenic diet, we see a shift away from the small dangerous LDL even when the total LDL goes up.
The diet’s strict limitation on starchy vegetables, whole grains, and fruits may lead to missing out on vitamins, minerals and other healthy compounds found in plant foods, which can lead to malnutrition, Bender adds. A true ketogenic diet could also lead to digestive and other unpleasant side effects. It requires monitoring and nutritional supplements. It can be difficult to follow.

One study assessed the effect of dietary interventions on quality of life, cognition and behavioural functioning, reporting participants in the KD group to be more active, more productive and less anxious after four months, compared to the control group. However, no significant difference was found in quality‐adjusted life years (QALYs) between the KD group and control group at four or 16 months (GRADE rating very low).


If you’ve decided to move forward in trying the keto diet, you will want to stick to the parameters of the eating plan. Roughly 60 to 80 percent of your calories will come from fats. That means you’ll eat meats, fats, and oils, and a very limited amount of nonstarchy vegetables, she says. (This is different from a traditional low-carb diet, as even fewer carbs are allowed on the keto diet.)
Insulin is a hormone that lets your body use or store sugar as fuel. Ketogenic diets make you burn through this fuel quickly, so you don’t need to store it. This means your body needs -- and makes -- less insulin. Those lower levels may help protect you against some kinds of cancer or even slow the growth of cancer cells. More research is needed on this, though.
Everyone talks about upping their fats… I do not think that is the key to sweeping LDL out of the system. Upping cruciferous fiberous veggies… the fiber, vitamins and minerals contained in veggies bind with the LDL and move it on out. You would have to eat literally a truck load to make any serious dent in your daily carb allowance since most are very low net carb anyways.

A well-formulated ketogenic diet, besides limiting carbohydrates, also limits protein intake moderately to less than 1g/lb body weight, unless individuals are performing heavy exercise involving weight training when the protein intake can be increased to 1.5g/lb body weight. This is to prevent the endogenous production of glucose in the body via gluconeogenesis. However, it does not restrict fat or overall daily calories. People on a ketogenic diet initially experience rapid weight loss up to 10 lbs in 2 weeks or less. This diet has a diuretic effect, and some early weight loss is due to water weight loss followed by a fat loss. Interestingly with this diet plan, lean body muscle is largely spared. As a nutritional ketosis state sustains, hunger pangs subside, and an overall reduction in caloric intake helps to further weight loss.
The day before admission to hospital, the proportion of carbohydrate in the diet may be decreased and the patient begins fasting after his or her evening meal.[19] On admission, only calorie- and caffeine-free fluids[37] are allowed until dinner, which consists of "eggnog"[Note 8] restricted to one-third of the typical calories for a meal. The following breakfast and lunch are similar, and on the second day, the "eggnog" dinner is increased to two-thirds of a typical meal's caloric content. By the third day, dinner contains the full calorie quota and is a standard ketogenic meal (not "eggnog"). After a ketogenic breakfast on the fourth day, the patient is discharged. Where possible, the patient's current medicines are changed to carbohydrate-free formulations.[19]
Now intrigued, I asked why he would want to change jobs, since our practice was by design slower paced, whereas Bob ran a very busy clinic and active IV unit which would seem perfectly suited for this nurse’s expertise. He then explained, with obvious disappointment, that none of the hundreds of cancer patients they had treated or had been treating had responded to any significant degree, with the exception of those he had referred to me.
Cholesterol is most commonly transported in the blood by molecules composed of fat and protein called lipoproteins. From least dense to most dense, they come in five forms: chylomicrons, very-low-density lipoproteins (VLDL), intermediate-density lipoproteins (IDL), low-density lipoproteins (LDL), and high-density lipoproteins (HDL). Because VLDL, LDL, and HDL cholesterol are frequently used as clinical indicators, we are going to focus on them.
The goal of a ketogenic diet is to transition the body’s primary fuel supply from carbohydrate to fat, creating a state of nutritional ketosis and, eventually, fat adaptation. The degree to which dietary carbohydrates need to be reduced to reach nutritional ketosis varies from person to person. Finding the optimal macronutrient ratios for getting your body into ketosis requires some self-experimentation. I recommend playing around with the ranges listed below to find the ones that work best for you.
At the core of the classic keto diet is severely restricting intake of all or most foods with sugar and starch (carbohydrates). These foods are broken down into sugar (insulin and glucose) in our blood once we eat them, and if these levels become too high, extra calories are much more easily stored as body fat and results in unwanted weight gain. However, when glucose levels are cut off due to low-carb intake, the body starts to burn fat instead and produces ketones that can be measured in the blood (using urine strips, for example).
Because people with type 2 diabetes are at an increased risk for cardiovascular disease, there’s a specific concern that the saturated fat in the diet may drive up LDL, or “bad,” cholesterol levels, and further increase the odds of heart problems. If you have type 2 diabetes, talk to your doctor before attempting a ketogenic diet. They may recommend a different weight-loss diet for you, like a reduced-calorie diet, to manage diabetes. Those with epilepsy should also consult their doctor before using this as part of their treatment plan.
Normoxic cancer cells also have the ability to use ketones as fuel for the TCA cycle, particularly 3-hydroxy-butyrate, in what has been called “The Reverse Warburg Effect.” 3-HB can increase tumor growth rate by ~250%. Cancer cells’ ability to use ketones for fuel may explain why diabetics are at increased risk of cancer (e.g. diabetic ketosis). [NCBI, “Ketones and lactate ‘fuel’ tumor growth and metastasis”]
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.
Cancer – One exciting frontier for the potential use of a ketogenic diet is as an adjunct treatment for certain types of cancers. In 1924 Otto Warburg first published his observation that, unlike healthy cells, nearly all cancer cells fuel themselves through glycolysis, a means of creating energy through the fermentation of glucose. What we now call the “Warburg Effect” has led many researchers to theorize that if cancer cells are starved of glucose, they will stop spreading, while healthy cells will continue to thrive on the alternative fuel source of ketones. In mice, a ketogenic diet is known to inhibit certain pathways and lower certain compounds involved in tumor formation.35 Research thus far is very preliminary, but because a ketogenic diet appears to target major energy pathways responsible for tumor growth and survival, it may enhance the efficacy of conventional treatments and even reduce side effects in some types of cancers. 36 37 38

When I was six years old, I was diagnosed with temporal lobe, partial-complex epilepsy.  Over the years, I have seen multiple doctors and neurologists and I have been on every medication created to treat epilepsy, but I still continued to have seizures about every 6-8 weeks. For the most part, I have been able to lead a normal life achieving my college degree, getting married and having two happy, healthy kids but every time I had a seizure it was a cruel reminder that I was not everything I needed to be for my family. Many times after a seizure, I would be unable to work and care for them for days at a time.
Before starting the diet, the patient should maintain a seizure diary to establish a frequency parameter. Also needed are a laboratory evaluation including selenium and carnitine levels (Table 5), electroencephalogram (EEG), and a magnetic resonance image (MRI) of the brain. A renal ultrasound should be done in case of kidney stones; an electrocardiogram and carotid ultrasound are considered optional (Kossoff et al., 2018). The nutritional evaluation includes a nutritional anamnesis including a 3-day food report, food habits, allergies, aversions, and intolerances. Baseline weight, height, and the ideal weight for stature and body mass index (BMI) are needed to calculate the ketogenic ratio, calories, and fluid intake. The diet formulation should be established according to the patient’s age and the administration route (Kossoff et al., 2009).

All of this talk about energy metabolism leads us to another important finding in the cancer literature: healthy cells can also become cancerous if their mitochondria (the primary energy producer of the cell) is dysfunctional for an extended period of time. Furthermore, if the cell is already cancerous, the mitochondrial dysfunction will make the cell’s genes vulnerable to additional mutations.


I just got to know too that my Cholesterol raised a lot, I've been on keto for a little more than 3 months and before that always had a low carb diet. I don't know if the 3 day fast I did before taking the blood test only " aggravated" the situation. The total is 302, LDL is 214! But since the triglycerides are 94 and HDL 57, it seems to be OK. I read that a low rate of TG/HDL may indicate that the LDL particles are of the bigger, fluffier type less dangerous.

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.

There are numerous benefits that come with being on keto: from weight loss and increased energy levels to therapeutic medical applications. Most anyone can safely benefit from eating a low-carb, high-fat diet. Below, you’ll find a short list of the benefits you can receive from a ketogenic diet. For a more comprehensive list, you can also read our in-depth article here >
Unfortunately, there’s no long-term data on ketogenic diets versus other diets. In a 2015 Italian study, those on a ketosis diet lost 26 pounds in three months. About half of the participants stayed on the diet for a year but lost little additional weight in the next nine months. People in a 2014 Spanish study who followed a very-low-calorie ketogenic diet lost an average of 44 pounds in a year—but a third of them dropped out, possibly because it was too hard to maintain.
For example, a pretty large number of animal studies have shown that a ketogenic diet can reduce tumor growth and improve survival rates. There was one 22-day study in mice that looked at the differences between the ketogenic diet and other diets. That study found that a ketogenic diet reduced tumor growth by up to 65% and nearly doubled survival time in some cases.
A ketogenic diet may be an option for some people who have had difficulty losing weight with other methods.  The exact ratio of fat, carbohydrate, and protein that is needed to achieve health benefits will vary among individuals due to their genetic makeup and body composition. Therefore, if one chooses to start a ketogenic diet, it is recommended to consult with one’s physician and a dietitian to closely monitor any biochemical changes after starting the regimen, and to create a meal plan that is tailored to one’s existing health conditions and to prevent nutritional deficiencies or other health complications. A dietitian may also provide guidance on reintroducing carbohydrates once weight loss is achieved.
Then there are some more experimental drugs that restrict the availability of glucose via inhibition of glycolysis and other processes. One of those drugs is called 2-DG, and that’s shown quite a bit of promise, so there’s not a lot of research on it yet, and then there’s an older drug named DCA, which also limits the availability of glucose. That has shown some promise, although it has known toxicity and side effects. It may not be a good choice for that reason.
“But if you’re a young and healthy adult, I have no safety concerns about removing carbs,” he adds. “It’s really not a radical concept.” You may experience some short-term issues like bad breath, constipation and flu-like symptoms. (Drinking lots of water can help.) But the lasting benefits could range from reduced hunger and increased energy to weight loss. Some preliminary research even hints at memory improvements.

Another mouse study cited by Seyfried is one in which dietary restriction was reported to promote vessel maturation in a mouse astrocytoma model. Given that tumor angiogenesis is one of my scientific interests and I have a fair number of publications on the topic, I was interested. Unfortunately, I ended up being disappointed. This was another syngeneic model (i.e., a mouse tumor implanted in mice of the same strain from which the tumor was isolated as a cell line, like the one discussed above). Although it showed increased tumor vessel maturation (which is one mechanism by which inhibitors of angiogenesis work), I wasn’t quite convinced, because there was a distinct lack of quantification of the phenomenon, and the microscopy appears not to have been blinded, something that’s critical to avoid unconscious bias in the results. It’s not surprising that this result, which, if more convincing evidence had been obtained, could easily have appeared in Cancer Research, was published in a low tier journal. It’s an OK study, but not fantastic. Certainly it didn’t lead me to smacking myself in forehead and saying, “Of course!”

Having first read Dr. Price’s book during my journalism days, I knew that according to his exhaustive work, humans were a varied species, in the past living in and adapting to all ecological niches excepting the Antarctic, offering a variety of food sources. To me, his work offered a solution to the conflicting dietary advice even then being offered to the world. It didn’t make sense as Nathan Pritikin insisted or as Bob Atkins argued, that all humans should follow one specific type of diet: It just didn’t seem reasonable, to me at least.
