Great article! I have been diagnosed with familial hypercholesterolemia, however, I am not concerned at all. I continue to follow a restricted calorie, zero carb ketogenic diet, that I have been doing strictly for the last year and a half. All of my health markers are excellent, except for LDL particle number and total, and it is the large buoyant type. I am middle-aged (46). I did get both a CT scan and tri-vascular scan, and got perfect scores for both. That alleviated any concerns that I might have previously had. Since this diet has improved my gut issues, bodyfat, blood pressure, insulin, blood glucose, mood, energy, A1C, CRP, etc., - basically every single health parameter I have tested, I am sticking with it! Thank you for clearing up the confusion surrounding LDL!
I’m certainly not an expert in cancer. Please keep that in mind when I say this, but I do tend to agree, just my overall view of most diseases, from what I’ve been able to gather, is that they are multifactorial, and I generally resist theories that seem to suggest that one disease has one cause. That’s unusual in my experience, from everything that I’ve seen. I wouldn’t necessarily say that. Dr. Seyfried and Dominic D’Agostino aren’t making that argument either, but I think what they bring to this is a fresh perspective that in many ways if it’s true, it can be more empowering for people that are dealing with cancer, and the risk of cancer, because it offers a lever for intervention and treatment above and beyond just the idea that “Oh, I have bad genes and there’s not really anything I can do about it.”
Despite these associations between high concentrations of LDL particles and heart disease, research has consistently shown that keto diets help reduce heart disease risk factors in people with diabetes and other insulin-resistant conditions. Granted these are not outcome trials, showing an actual reduction in heart attacks, but those trials simply don’t exist one way or the other. Yet the reduction in risk factors certainly suggests that we may eventually see those beneficial results.

Leftovers will be another thing we will take into consideration. Not only is it easier on you, but why put yourself through the hassle to cook the same food more than once? Breakfast is something I normally do leftover style, where I don’t have to worry about it in the morning and I certainly don’t have to stress about it. Grab some food out the fridge, pre-made for me, and head out the door. It doesn’t get much easier than that, does it?
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.
You may find it easy to eat less when all you can eat is protein and fat. But after a while, you may grow tired of bringing your own whole salmon to parties, and wonder what the other 95% of the grocery store is up to. You may start to have fantasies about a threesome: you, Oreos, and chocolate sauce. Not only that, you may be getting some serious scurvy and other nutrient deficiencies.
Often caused by lymph node removal or damage due to cancer treatment, lymphedema occurs because there’s a blockage in the lymphatic system and results in the swelling in leg or arm. A 2017 study involved patients who suffered from obesity and lymphedema and who embarked on a 18-week ketogenic diet. Weight and limb volume was significantly reduced. (5)
Keto diets are high in healthy fats and protein also tend to be very filling, which can help reduce overeating of empty calories, sweets and junk foods. (4) For most people eating a healthy low-carb diet, it’s easy to consume an appropriate amount of calories, but not too many, since things like sugary drinks, cookies, bread, cereals, ice cream or other desserts and snack bars are off-limits.

Ketogenic diets (some using calorie restriction) have been associated with decreased tumor growth in animal models of gliomas [10], prostate cancer [25], and gastric cancer [11]. In the context of cancer, ketone bodies may provide an alternative substrate for ATP production in malignant cells, as outlined above. However, other work suggests that glucose is used to produce components critical to proliferative cell growth [26], and it is conceivable that the ketogenic diet may restrict that aspect of malignant cell transformation.

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.

Tumors have hypoxic zones and normoxic (aerobic) zones, with a symbiotic relationship between the two. Hypoxic cancer cells derive energy from fermentation of glucose, and secrete lactate. Normoxic cancer cells prefer and attract lactate as fuel for the TCA cycle, sparing glucose for the hypoxic cells. [NCBI, “Tumor cell metabolism: an integral view”]
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.

By the time I began medical school in 1979 I had read the pioneering work of Weston A. Price, DDS, the American dentist and researcher. Beginning in the late 1920s, Dr. Price, accompanied by his wife, spent seven years traveling the world evaluating isolated groups of people living and eating according to long-standing tradition. Today such a study would be impossible, since just about everyone everywhere has adopted the “Western” way of living and eating, down to jeans and junk food.
When a person first starts onto a low-carbohydrate ketogenic diet, it takes the body several days to a few weeks to shift from relying on glucose to instead rely on fat. During this transition, people may experience what is sometimes referred to as the “keto-flu”—muscle cramps, headaches, fatigue, dizziness, nausea, and sugar and carbohydrate cravings.49 There may also be increased urination which can result in a loss of minerals, such as sodium and potassium. To counter these effects one should strive to get more minerals and in particular, more sodium and potassium, drink plenty of water, get some exercise and ensure adequate caloric intake. Once the body becomes keto-adapted, these symptoms largely resolve, and many people report increased energy, decreased cravings and weight loss.
The glowing TV stories followed, including a memorable prime time, one-hour special about the subject on ABC hosted by the late Peter Jennings. The other networks, in quick succession, picked up the cause. However, not too long after, word broke that Times’ reporter Kolata had been, through her agent, hawking to publishers an idea for a book about anti-angiogenesis and cancer.
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].
I’m 50 and have been working out with weights and cardio for over 30 years, 6-7 days per week. I have always had controlled weight in the 180’s for 5′ 9″ due to strength training. I went on a “version” of the Keto diet—per day goals: 35 net carbs/85-95 grams protein/35-40 grams fat. I didn’t want to go all-in with high fats. I weighed 188 at the start and in 6 months dropped 26 lbs to 162, and bodyfat at 9%. My cholesterol levels have mostly been 220 with 50-75 HDL.
This describes me, too. I am not a doctor, but after months and years of research, have decided to follow the ketogenic lifestyle and the naturopathic cancer treatments prescribed by my physician. It took a few months to find a doctor who embraced this, but he is worth it. Keto had my diabetes under control long before we realized that cancer was trying to get me as well. I take no chemical drugs for anything. Diet, exercise, and a few supplements take care of my health needs. You don’t know me, but three years ago, I needed a walker and a wheelchair. Today at 60, I walk under my own power and ride a bicycle as much as possible. Go as natural as you can, it helps. Stay away from “products” and just eat fresh, whole, natural food.
