A keto diet has shown to improve triglyceride levels and cholesterol levels most associated with arterial buildup. More specifically low-carb, high-fat diets show a dramatic increase in HDL and decrease in LDL particle concentration compared to low-fat diets.3A study in the long-term effects of a ketogenic diet shows a significant reduction in cholesterol levels, body weight, and blood glucose.

Thanks Dr. Jockers…very informative article. Im into pure keto diet almost a week now but started illiminating sugar and carbs 3weeks ago and the side effects that i’ve encountered are frequently urinating and light headache only. Is it good or not? I’ve never consult a specialist before doing keto diet but i do my research, is it okay? As of now i’ve loose almost 11lbs. Im just curious how can i get the percentage of fats, protein etc in my meals? Do i need to measure it all? How can i measure the percentage of foods that i need to eat?is there any ways?
Ketoacidosis occurs mainly in people with type 1 diabetes if they do not take insulin. In diabetic ketoacidosis (DKA), blood sugar and ketones rise to dangerous levels, which disrupts the blood’s delicate acid-base balance. People in ketoacidosis feel extremely ill and experience profound dehydration, vomiting, abdominal pain, and weakness. DKA requires hospitalization so that IV fluids and insulin can be given to gradually and safely lower blood sugar.
Researchers believe that genetics likely plays a role here, making some people more susceptible to liver problems when following low-carb, high-fat diets. Is the keto diet bad for your kidneys? According to an article released by Harvard Medical School, “Patients with kidney disease need to be cautious because this diet could worsen their condition.”
Restricting carbohydrates. Studies show that after three or four days without carbohydrate consumption, your body starts tapping its fat storage also known as ketosis. You’ll want to stay between 25–35 grams of carbs to get into ketosis, and that requires bucking mainstream, carb-heavy, and supposedly nutrient-rich foods like fruit and grains. There are good carbs you can eat that will help you stay in ketosis. Be sure to look over these more keto diet friendly fruit options.
Ketosis has a protein-sparing effect, assuming that you are consuming adequate quantities of protein and calories—0.7 grams per pound of body weight per day—in the first place. Once in ketosis, the body actually prefers ketones to glucose. Since the body has copious quantities of fat, this means there is no need to oxidize protein to generate glucose through gluconeogenesis.
What sort of negative health effects might an overly acidic pH level contribute to? A few include: bone loss, muscle loss, and higher susceptibility to frequent infections or illnesses. One way to track if your body is adapting well to an alkaline diet is testing your urine pH level. The pH scale ranges from 1–14, with seven being neutral and anything higher than seven beings alkaline. The goal is to ideally have a urine alkaline pH level between of 7.0–7.5 (a number that is slightly more alkaline than acidic).
Statistical differences between body weight, total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides, level of fasting blood sugar, and urea and creatinine levels before and after the administration of the ketogenic diet were analyzed using a paired Student’s t test using the Stat-view version 4.02 (Abacus Concepts Inc, USA). Weight, BMI and all biochemical parameters are expressed as mean ± SEM.
Dementia and Alzheimer’s Disease A small study published in February 2013 in the journal Neurobiology of Aging found that older higher-risk adults on a keto diet experienced better memory functioning after just six weeks. (11) Some experts, like Richard Isaacson, MD, director of the Alzheimer’s Prevention Clinic at Weill Cornell Medicine and NewYork–Presbyterian in New York City, support low-carb diets for patients as one way to delay brain aging and possibly Alzheimer’s disease, the most common form of dementia.
The good news is, it is not necessary to stay on a ketogenic diet at all times to reap this benefit. Our ancestors went through fast and feast cycles and the body is designed for flexibility. We may be able to reduce cancer risk, prolong life, improve brain function, and benefit from ketosis otherwise by being in ketosis or fasting a few days a week.
Diabetes is actually a metabolic problem. It’s characterized by the hormone insulin no longer exerting its important actions appropriately. Your cells and tissues don’t ‘hear it knocking’ so to speak. So you produce more and more insulin, which eventually fatigues your pancreas. This deluge of insulin (hyperinsulinemia) you now find yourself bathing in also causes your fat stores to release fat inappropriately. This ultimately swamps your liver with excess fat (energy). To reduce the excess energy, your liver handles starts frantically producing and pumping out lots of blood glucose. This task (gluconeogenesis) is costly and momentarily solves your liver’s crisis of energy excess. The longer-term cost however are serious consequences like high blood sugars, unstable energy levels, damaged tissues (via glycation and ROS), neurodegeneration and worse body composition (with fat usually stored in the wrong places), etc.
Keto cycling is a way to cycle in and out of ketosis while enjoying a more balanced diet on your "days off." One keto cycling approach includes five days of traditional keto diet and two non-keto days per week. Some people choose to save their off days for special occasions holidays, birthdays, and vacations. For best results, eat wholesome carbohydrate-rich foods on your off days, including fruits, starchy veggies, dairy products, and whole grains (rather than added sugars or highly-processed fare).
There is exciting research on the role of a keto diet as a form of treatment for cancer. In one study, the use of a keto diet on patients with advanced cancer was deemed safe, and some evidence suggested it played a role in stabilizing the disease or resulting partial remission. In another study, the keto diet was used as a form of therapy for patients with malignant brain cancer. The study found that the keto diet may carry anti-tumor effects when administered in experimental animal and human brain tumors. The researchers believe this may be due to the reduction in calories, which reduces the circulating glucose needed for tumor growth. It is still unsure whether a keto diet per se plays a role in this or simply calorie restriction. All of this is to say that the research is preliminary, however still promising.

Click here to join my newsletter and I’ll keep you posted when I get new articles up (FYI: as a heads up, I also write about entrepreneurship and web development. I started writing about fat metabolism and ketogenic dieting here at KetoSchool out of pure hobby interest, as there are relatively few resources out there that teach the underlying science).
“constant keto supposedly caused selenium deficiency and stunted growth in epileptic kids on keto diets. As I previously commented large areas of North America & Western Europe have Se-deficient soils with the notable exception of the NA grain-growing regions. Consequently the major source of Se in the SAD is grains and deficiency is a result of eliminating the grains on a Keto or WB diet. Opponents could just as easily use Se-deficiency as an argument against WB. The solution is not eating grains it’s taking a supplement.
In 2013, researchers published a case study of two women with bipolar II who ate long-term ketogenic diets, one for two years and the other for three years. The authors reported that both “experienced mood stabilization that exceeded that achieved with medication; experienced a significant subjective improvement that was distinctly related to ketosis; and tolerated the diet well.” They noted, too, that “there were no significant adverse effects in either case” and that the two cases “demonstrate that the ketogenic diet is a potentially sustainable option for mood stabilization in type II bipolar illness.” .
The keto diet restricts carbs so much that anyone who is on blood sugar lower medication or who has type 1 or type 2 diabetes must consult his or her doctor before making such a severe dietary change. As the body adapts to low-carb dieting, medication dosages and treatment plans will have to be revised, and blood sugar levels must be carefully monitored.
🙌🙌 thank you for some great info! USC just had an article about Keto, saying they don’t know the impact on bone health. So I’m not sure why all these articles are written without the documentation to prove the claims. We all know too much calcium supplementation can cause problems but every Dr wants you to supplement calcium. Most people could do a lot worse than doing Keto! The SAD will cause more problems for you than eating whole, unprocessed Keto food! Sugar seems to be the real issue along with aspartame and stressful living.

Work towards cycling fasting days so you’re fasting on 2–3 nonconsecutive days per week (e.g. Tuesday, Thursday and Saturday). Stick to only light exercise or yoga on fasting days to reduce feeling exhausted or hungry, keeping higher intensity activities for your non-fasting days. This approach allows for more dietary and lifestyle “moderation” because the goal isn’t to eat 100 percent “perfectly” all the time.
