For many years, LDL-C tests have been used as the primary method of measuring LDL in the blood. It is cheaper and easier to measure. Recent research has called into questioning how effective LDL-C is compared to LDL-P in precisely assessing cardiovascular risk. After reviewing cross-sectional data, a recent peer-reviewed paper from the world-renowned Framingham Heart Study stated that
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.
The ketogenic diet also has been used in glycogenosis type V (McArdle disease), which is caused by a defect in the muscle-specific isozyme of glycogen phosphorylase. Glycogen phosphorylase is necessary to break down glycogen into free glucose for use as an energy source in muscles. When the ketogenic diet was applied to a patient with this disorder (presumably providing an alternative means of energy production), the patient’s exercise tolerance improved and there was a trend toward decreased baseline creatine kinase levels [22, Class III].
Cyclical ketosis means you’re sometimes in ketosis and sometimes aren’t. A few days each week—the night before workout days to build glycogen stores in your muscles—try increasing your intake of berries, higher complex carb veggies (like sweet potatoes), and non-gluten grains. It might knock you out of ketosis temporarily, but it also provides a wealth of nutrients to keep you lean, healthy, and happy. This is also called flexible ketosis, which creates metabolic flexibility—the holy grail of metabolism management. I’ve also talked about cycling ketosis with intermittent fasting, which provides a win-win strategy to reach your health goals.
The goal is to reach a ratio of four portion of fat to one portion of protein plus carbohydrate, described as “4:1.” To achieve this level, one of two approaches, with or without fasting, may be used. In the former approach, the patient must be hospitalized for 12–48 h, or when ketones are present in the urine (Rubenstein, 2008), to prevent the development of hypoglycemia and dehydration. This method tends to accelerate the development of ketosis although it can generate more stress on the patient (Armeno et al., 2014). When ketosis is reached, the meals are calculated to maintain a constant KD ratio, while calories are added until full-calorie meals are tolerated (Kossoff et al., 2009). The latter approach requires no hospitalization and the KD ratio increases weekly, from 1:1, 2:1 and 3:1 to 4:1 (Bergqvist et al., 2005). Most of the literature suggests that there is no significant difference between the two approaches in terms of the time needed to reach ketosis and the occurrence of hypoglycemia (Kim et al., 2004), so nowadays patients tend to not fast.
With all due respect Dr. Kresser, I’m not aware of any cancer is reversed under Ketogenic diet. It’s all just a bunch of pretty theory but nothing in practice. As we speak there are probably thousands of people tried and done Ketogenic diet both for “health” reason and cancer cure. And yet… no report ever surface of the success of Keto diet in reversing cancer.
People use a ketogenic diet most often to lose weight, but it can help manage certain medical conditions, like epilepsy, too. It also may help people with heart disease, certain brain diseases, and even acne, but there needs to be more research in those areas. Talk with your doctor first to find out if it’s safe for you to try a ketogenic diet, especially if you have type 1 diabetes.
One potential confounder of ketogenic diet studies is another direct effect of the diet—increased levels of fatty acids. Dietary supplementation of essential fatty acids can improve cognitive dysfunction, including in patients with AD [44, Class II]. This suggests that something other than ketone bodies (in this case, essential fatty acids) may have beneficial effects in neurodegenerative diseases. Essential fatty acids may have a beneficial effect on learning in rodent models, raising the possibility that they may have neuromodulatory properties of their own [45,46].
Many versions of ketogenic diets exist, but all ban carb-rich foods. Some of these foods may be obvious: starches from both refined and whole grains like breads, cereals, pasta, rice, and cookies; potatoes, corn, and other starchy vegetables; and fruit juices. Some that may not be so obvious are beans, legumes, and most fruits. Most ketogenic plans allow foods high in saturated fat, such as fatty cuts of meat, processed meats, lard, and butter, as well as sources of unsaturated fats, such as nuts, seeds, avocados, plant oils, and oily fish. Depending on your source of information, ketogenic food lists may vary and even conflict.
More recently, the famed New York diet doctor, Robert Atkins, MD, popularized the ketogenic diet, not for cancer, but as the ultimate weight loss plan with his books over the decades selling in the tens of millions of copies. The original version of the Diet Revolution published in 1972 sold at one point more than 100,000 hard copies a week, in those days the fastest selling book in the history of United States publishing.
Jimmy Moore: Quite frankly. They’ve not been trained to teach you how to do nutrition, and then if they turn to nutrition they either leave it to the dietitian who has been trained in low fat, high carb diets or they’ll just “Well, the USDA my plate says blah blah blah.” They’re just parading what someone else has said. They’ve not done their own research. Just assuming that your doctor knows everything about what it takes nutritionally to make you healthy is a bad mistake.
The ketogenic diet for epilepsy (KDE) was developed in the 1920s by Dr. Hugh Conklin in Michigan. But once effective medications were developed, the diet was used less frequently. It has regained recognition and study and is now a standard backup plan for children whose epilepsy symptoms are difficult to control with medication. With over 300,000 children in the U.S. with seizure disorders, this has become an important addition to the arsenal of treatments for epilepsy. Researchers are beginning to see how it might help adults and people with a variety of neurologic disorders.
Variations on the Johns Hopkins protocol are common. The initiation can be performed using outpatient clinics rather than requiring a stay in hospital. Often, no initial fast is used (fasting increases the risk of acidosis, hypoglycaemia, and weight loss). Rather than increasing meal sizes over the three-day initiation, some institutions maintain meal size, but alter the ketogenic ratio from 2:1 to 4:1.
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)?
After increasing water intake and replacing electrolytes, it should relieve most all symptoms of Keto Flu. For an average person that is starting a ketogenic diet, eating 20-30g of net carbs a day, the entire adaptation process will take about 4-5 days. My advice is to cut your carbs to fewer than 15g to ensure that you are well on your way into ketosis within one week. If you are experiencing any more keto flu symptoms, double check your electrolyte intake and adjust.
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.
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.
A recent study found that ketone supplementation extended survival in mice with metastatic cancer. But while it’s true that most cancers have a highly anaerobic metabolism, this in not universal. If proven to be effective, it’s likely that ketone supplementation would be an additional treatment rather than a stand alone treatment for cancer, because of its robust nature.
Weight loss is the primary reason my patients use the ketogenic diet. Previous research shows good evidence of a faster weight loss when patients go on a ketogenic or very low carbohydrate diet compared to participants on a more traditional low-fat diet, or even a Mediterranean diet. However, that difference in weight loss seems to disappear over time.
Our bodies are incredibly adaptive to what you put into it – when you overload it with fats and take away carbohydrates, it will begin to burn ketones as the primary energy source. Optimal ketone levels offer many health, weight loss, physical and mental performance benefits.1There are scientifically-backed studies that show the advantage of a low-carb, ketogenic diet over a low-fat diet. One meta-analysis of low-carbohydrate diets showed a large advantage in weight loss. The New England Journal of Medicine study resulted in almost double the weight loss in a long-term study on ketone inducing diets.

Weight loss was also irresistible. I actually tried not to lose weight. Based on advanced bro science, I was supposed to maintain my weight if I ate at least 2,000 calories a day. Yet my efforts to stuff myself with gloriously fatty food were futile. I lost 10 kilos and got abs — “blurry” ones though. You still need a bit of imagination to count six.
