Jimmy Moore: That’s exactly what’s happening inside your body when you have less cholesterol and you have higher levels of inflammation in your body. You’re putting your body at risk because those fire fighters aren’t there. The cholesterol to put out the fire of inflammation and so we really have to know where we stand with inflammation and without the inflammation, there really is no heart disease. People are, “Oh you have 289 total cholesterol, you’re at great risk for heart disease.”
Hi Gigi, Low carb and keto is about the balance of macronutrients eaten (fat, protein and carbs), not specifically meat or lack thereof. Most people on keto do eat meat, though some people do vegetarian keto. Fat is actually necessary for many body processes. There is no issue for the kidneys with a high fat diet, but if you eat too much protein that isn’t great for the kidneys. It’s a common misconception that keto is high protein (it isn’t). Keto is great for diabetics as it naturally helps stabilize insulin. All of this being said, please know I’m not a doctor and you should consult your doctor on any medical questions or before starting any diet. If you have more questions that aren’t medical questions, I recommend our low carb & keto support group here.
In essence, it is a diet that causes the body to release ketones into the bloodstream. Most cells prefer to use blood sugar, which comes from carbohydrates, as the body’s main source of energy. In the absence of circulating blood sugar from food, we start breaking down stored fat into molecules called ketone bodies (the process is called ketosis). Once you reach ketosis, most cells will use ketone bodies to generate energy until we start eating carbohydrates again. The shift, from using circulating glucose to breaking down stored fat as a source of energy, usually happens over two to four days of eating fewer than 20 to 50 grams of carbohydrates per day. Keep in mind that this is a highly individualized process, and some people need a more restricted diet to start producing enough ketones.
On the ketogenic diet, carbohydrates are restricted and so cannot provide for all the metabolic needs of the body. Instead, fatty acids are used as the major source of fuel. These are used through fatty-acid oxidation in the cell's mitochondria (the energy-producing parts of the cell). Humans can convert some amino acids into glucose by a process called gluconeogenesis, but cannot do this by using fatty acids. Since amino acids are needed to make proteins, which are essential for growth and repair of body tissues, these cannot be used only to produce glucose. This could pose a problem for the brain, since it is normally fuelled solely by glucose, and most fatty acids do not cross the blood–brain barrier. However, the liver can use long-chain fatty acids to synthesise the three ketone bodies β-hydroxybutyrate, acetoacetate and acetone. These ketone bodies enter the brain and partially substitute for blood glucose as a source of energy.
The authors defined a VLCKD as a diet lower in 50g of carbohydrates – lower than the daily recommended grams of carb consumption clinicians recommend to diabetics. They included 13 randomized controlled studies with a total of 1,415 subjects. All studies took place for at least a full year and all subjects included were over 18 years old and had a BMI of at least 27.5 kg/m2. In each of these studies, VLCKD diets were compared to low-fat diets.
In the 1920s, German scientist Otto Warburg found that cancer cells fuel their growth through metabolizing a large amount of glucose. Unlike the average healthy cell, he saw that cancer cells were converting glucose into energy without using oxygen, even when oxygen was readily available. Now called the Warburg effect, this phenomenon is seen in about 80 percent of cancers.
It’s not heart healthy because it’s raising inflammation. The reason they put in on there though is it does one thing on your cholesterol panel that they think is good. It lowers the LDLC number. It does. It will do it all day everyday. You can sit there and drink Canola oil, and your LDL will go down, your LDLC. That LDLC is just a calculated number using this thing called the Friedewald equation and it’s not directly measured. That’s another thing people don’t realize. LDLC is just totally an estimated number. When your triglycerides are under 100 and your HDL is over 50, it totally miscalculates what your LDL is. That’s why that NMR lipo profile test to know the particles is so important. I know I’m talking fast and saying a lot of technical terms.
The ketogenic diet is a high-fat, low-carbohydrate diet that's recently become popular for weight loss. But the diet has been used to treat epilepsy since the 1920s, according to the Epilepsy Society, a charity in the United Kingdom. Although most people with epilepsy today control their seizures with anti-epileptic drugs, the diet is sometimes prescribed to children with epilepsy who have not responded to several medications.
Following a ketogenic diet puts your body into a state of “ketosis,” which is a metabolic state that occurs when most of the body’s energy comes from ketone bodies in the blood, rather than from glucose from carbohydrate foods (like grains, all sources of sugar or fruit, for example). This is in contrast to a glycolytic state, where blood glucose (sugar) provides most of the body’s fuel (or energy).
I’m not going to shell out 20k to know my LDL-P. I’d rather assume that I’m part of the 30% who reacts to saturated fat with elevated LDL-P. Should I be worried, considering all my other markers point to the right direction? Expert after expert say that we don’t know what these mixed signals mean until there is a study of people doing low-carb high-fat diets, correlating their lipid profiles with incidence of cardiovascular disease.
• High-protein ketogenic diet — This method is a variant of the SKD. In a high-protein diet, you increase the ratio of protein consumption to 10 percent and reduce your healthy fat consumption by 10 percent. In a study involving obese men that tried this method, researchers noted that it helped reduce their hunger and lowered their food intake significantly, resulting in weight loss.11
Whatever the source of protein you consume, make sure they are organic grass fed and antibiotic-free, as they are generally healthier and safer for your body. In one study, researchers indicated that grass fed beef (regardless of cuts) contains more omega-3 acid and conjugated linoleic acid compared to grain-fed beef.21 As for non-meat sources of protein, try to look for organic and pesticide-free varieties.
"The keto diet is primarily used to help reduce the frequency of epileptic seizures in children. While it also has been tried for weight loss, only short-term results have been studied, and the results have been mixed. We don't know if it works in the long term, nor whether it's safe," warns registered dietitian Kathy McManus, director of the Department of Nutrition at Harvard-affiliated Brigham and Women's Hospital.
Chris, I’m missing the logic here. Even when carbohydrates are restricted, the body is going to take fats and glycogen and turn them back into blood sugar, i.e. glucose. Glucose is also the only fuel the brain can use, and when it is too high or too low, all kinds of alarm bells go off, and the body does everything it can to restore normal glucose levels. Ketogenic diet or not, blood sugar is going to stay pretty steady if all the normal regulatory mechanisms are in place. If there is glucose in the blood, there is glucose in the interstitial fluids, and cancer cells are never going to be starved for glucose. So if restricting carbs has any use in cancer therapy, it has nothing to do with preventing cancer cells from getting glucose. If there is no glucose in the blood, you are dead.
There is no hard evidence that meat itself causes cancer. There is evidence that people who eliminate meat have a slightly lower cancer rate. This can be explain bc people who eliminate meat are usually doing so bc it is perceived to be “healthy” which means they are also eliminating/limiting foods such as coke, junk food, and other highly processed/high in sugar foods. These same people are also more likely to do some type of exercise where as the “meat-eaters” they are comparing them against are eating a highly processed, junk food, standard American diet and are also more likely to smoke and have limited exercise. Correlation is not causation.
As I ponder this enthusiasm, I have to think that perhaps I am just a little slower, or more cautious, than most. The day after I first met Dr. Kelley in New York in July 1981, I was on a plane to Dallas to begin my review of Kelley’s charts. As previously discussed, I quickly found among Kelley’s records case after case of appropriately diagnosed poor-prognosis and/or terminal cancer, patients alive five, ten, even 15 years later, with no possible explanation for such survival other than Kelley’s odd nutritional treatment.
A Cochrane systematic review in 2018 found and analysed eleven randomized controlled trials of ketogenic diet in people with epilepsy for whom drugs failed to control their seizures. Six of the trials compared a group assigned to a ketogenic diet with a group not assigned to one. The other trials compared types of diets or ways of introducing them to make them more tolerable. In the largest trial of the ketogenic diet with a non-diet control, nearly 38% of the children and young people had half or fewer seizures with the diet compared 6% with the group not assigned to the diet. Two large trials of the Modified Atkins Diet compared to a non-diet control had similar results, with over 50% of children having half or fewer seizures with the diet compared to around 10% in the control group.
In my previous articles, I discussed my friend, the late Dr. Robert Atkins, the famed diet doctor, who long before Dr. Seyfried appeared on the scene hoped his “ketogenic” diet might be an answer to cancer. During the late 1980s and right through most of the 1990s, Dr. Atkins treated hundreds of cancer patients, many, though not all, with a ketogenic diet, along with a variety of supplements and intravenous vitamin C.
