One reason it's hard to determine the exact health effects of diets is that it's often unclear whether any observed effects come from the diet or from a combination of other factors, like stress, environment or genetics. Still, that doesn't mean all the bold claims about the keto diet are wrong, but rather that you should approach them with a healthy degree of skepticism.
After reading that article I have to say that the “USC experts” are full of it. It’s the usual scare stuff that the mainstream docs and dietitians trot out to attempt to discredit LCHF and keto diets. There’s no reason why a keto diet should be any worse for bone health than any other diet provided it has adequate calcium, phosphate and Vit K2 and you have good Vit D levels. As for the recommendations of dietitians – eat lots of healthywholegrains and “vegetable” oils but no saturated fats – we know what the long-term results are of that: diabetes, heart disease and osteoporosis.
You may be able to tell that you're in ketosis by a change in your breath (many report halitosis, or bad breath, due to higher levels of the ketone acetone coursing through the body). Others experience the keto flu for anywhere from one day to two weeks as the body cranks up the ketones. Symptoms of the keto flu are very similar to the influenza virus, including nausea, fatigue, vomiting and diarrhea. Hydrating well and starting slowly can reduce your risk for this.
Prior to the advent of exogenous insulin for the treatment of diabetes mellitus in the 1920's, the mainstay of therapy was dietary modification. Diet recommendations in that era were aimed at controlling glycemia (actually, glycosuria) and were dramatically different from current low-fat, high-carbohydrate dietary recommendations for patients with diabetes [1,2]. For example, the Dr. Elliot Joslin Diabetic Diet in 1923 consisted of "meats, poultry, game, fish, clear soups, gelatin, eggs, butter, olive oil, coffee, tea" and contained approximately 5% of energy from carbohydrates, 20% from protein, and 75% from fat . A similar diet was advocated by Dr. Frederick Allen of the same era .
This was very confusing and disappointing to read from Dr. D. Wheatbelly IS ketogenic. In fact, I got kidney stones while following it, along with some other weird symptoms like hair loss and very cold hands and feet. Granted I was probably dehydrated and lacking in some nutrients……but still. I never had those issues while following SAD. On SAD I never worried about drinking enough water or whether I was getting the right scientifically controlled combination of vitamins, minerals, pro/pre biotics. Never had to eat a raw potato or, dear God, a hard, chalky, green banana (who can do that for life? No one). I never got a kidney stone (or the other mentioned symptoms) on SAD. And they all went away when I stopped doing Wheatbelly. Very disappointing because I was losing weight on Wheatbelly and have gained it all back. Anyway, the diets are very similar. If you restrict carbs the way Dr. D says you should…. for life, you will be in ketosis long term.
"Those with type 1 diabetes should avoid a ketogenic diet," warns Joseph Galati, MD, a hepatologist at the Liver Specialists of Texas in Houston, "Many patients with type 1 diabetes have some degree of renal impairment, and handling the build-up of ketones and acids in the body may cause too much stress on the kidneys. Of course, any pregnant women with diabetes, especially those requiring insulin should avoid such an extreme diet given the low glucose levels will be a constant [health] threat."
You have about 160,000 Kcals of fat available to burn – producing your own glucose in the process when needed (for anaerobic bursts). In contrast you only store around 400 to 500 Kcals of glucose/glycogen ready for use so if you are not adapted to burning fat then you are physically dependent and addicted to eating carbs. When you hear of a runner “hitting the wall” it’s only because of their unnatural carb addiction – an efficient fat burning athlete can run all day and will never have this problem. The human body is specifically designed to run long distance and can outrun almost every other animal on this planet – we can even run though intense heat because we sweat.
What is more common throughout the history of the human race is fasting. Islamic Ramadan is a 28- to 30-day fast where food and drink are prohibited during the daylight hours. Christianity also has a strong fasting foundation, and in the Bible, Jesus fasted to have higher and clearer communication with God. Greek Orthodox Christians fast for a total of 150–200 days each year!
Obesity Compared with those on a typical low-calorie diet, obese individuals on a very-low-calorie ketogenic diet lost more weight and inflammatory visceral (belly) fat in one study, published in December 2016 in the journal Endocrine. (9) It may also help preserve lean body mass during weight loss, according to an article published in February 2018 in the journal Nutrition & Metabolism. (10)
Until recently, ketosis was viewed with apprehension in the medical world; however, current advances in nutritional research have discounted this apprehension and increased public awareness about its favourable effects. In humans, ketone bodies are the only additional source of brain energy after glucose (23,24). Thus, the use of ketone bodies by the brain could be a significant evolutionary development that occurred in parallel with brain development in humans. Hepatic generation of ketone bodies during fasting is essential to provide an alternate fuel to glucose. This is necessary to spare the destruction of muscle from glucose synthesis.
The only issue with keto, is really that I’m afraid that it might be hard to up my calories to a maintenance weight now that I’ve gotten a taste preference for the rich assortment of foods with no carbs in them. I’m satisfied with less calories than I will need after my excess fat is burned off… but , maybe I bet my body will send more hunger signs once there isn’t anymore body fat in the cupboard to use instead of what goes down my throat.
For some, ketosis can cause more negative than positive side effects. Dorena Rode, a 52-year-old author, and speaker from Occidental, California, tried the diet for a month and experienced heart palpitations and dizziness. Unlike Drew, Rode says her cholesterol increased from 192 to 250 mg/dL after she introduced more fat into her diet. (Less than 200 mg/dL is considered desirable, while anything over 240 mg/dL is considered high.)
Also, if you listen to Dr Bernstein talk about his childhood (he is well into his 80’s), the “original” recommended diet was only ketogenic in the sense that it was high-carb and caused keto-acidosis, which he describes as almost killing him as a teenager. He still considers the ADA recommendations as ketogenic for this reason (you only have to listen to him a short time to hear him railing against the ADA).
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.” .
That makes a lot of sense. Keeping up insulin pathways when you aren’t eating carbs would be like keeping the lights on when it’s daytime outside — it’s a waste of energy. You aren’t using insulin on keto, so your body probably downregulates your insulin pathways. As a refresher, insulin is a hormone produced by your pancreas that tells your cells to absorb glucose to use as fuel. When you eat carbs, insulin production begins. In the absence of carbs, there’s less need for insulin.
Doctors can measure levels of inflammation in the body using blood tests for high-sensitivity C-reactive proteins (hsCRP) and white blood cell (WBC) counts. In Dr. Phinney’s study, “patients experienced a hsCRP reduction of 39 percent, and white blood cells were reduced by 9 percent,” Dr. Phinney says. “Similar results were demonstrated in a two-year study, which showed a 29 percent decrease in hsCRP following a low-carbohydrate diet.” Inflammation, Dr. Phinney notes, is directly associated with many different health conditions, such as heart disease, diabetes, arthritis, and autoimmune conditions. “It is very possible that reducing inflammation through nutritional ketosis could improve a whole host of conditions,” he says. These 10 keto diet recipes are reason enough to give it a try.
Avocados are the poster child of “good fats.” This type of fat, often found in plant-based foods, can be separated into polyunsaturated fats (found in fish and walnuts) and monounsaturated fats (found in avocados, flaxseed oils, nuts and seeds). There’s evidence that replacing saturated fats with “good” unsaturated fats can lower the risk of heart disease and help prevent insulin resistance.4
In addition, on the day the diet was initiated, diabetes medications were reduced – generally, insulin doses were halved, and sulfonylurea doses were halved or discontinued. Due to the possible diuretic effects of the diet soon after initiation, diuretic medications were discontinued if of low dosage (up to 25 mg of hydrochlorothiazide or 20 mg of furosemide) or halved if of higher dosage. Participants were also instructed to take a standard multivitamin and drink 6–8 glasses of water daily, and were encouraged to exercise aerobically for 30 minutes at least three times per week.
If you want to use a ketogenic diet as a health tool, it would be wise to do so for no more than a few weeks at a time, as nobody knows how long is too long. And, of course, the period of time during which ketosis is safe can vary from individual to individual. Breaking ketosis is as easy as upping protein intake or having a glass of wine or whole piece of fruit.
Type 2 diabetics may be on a range of medications that only treat symptoms, have serious side-effects and leave root causes unaddressed. Medications like Metformin may still make sense to use while reversing diabetes with a ketogenic diet. However, most if not all drugs like insulin and sulfonylureas can and should be discontinued. A note of caution though, changing doses or discontinuing medications is something you should do with the help of your doctor (or at the keep them informed).
There are many physiological reasons for eating enough carbohydrates throughout the waking hours to maintain a steady blood glucose level…a couple of important reasons are to minimize the hepatic release of glucose (from the liver) and to help prevent hypoglycemia which can be very dangerous and lead to hypoglycemic unawareness over a short period of time. Each person is different of course..if you aren’t taking insulin, or pills that lower your blood glucose levels, you may not have to worry about low blood sugars. The reality is, most people with diabetes do; it can be very dangerous for some to not get enough carbohydrates at each meal.
The keto diet has also been studied as a possible cancer therapy. In a study focusing on people with cancer who followed the ketogenic diet as a medical therapy,4 the authors reported: “There is a great need for complementary approaches that have limited patient toxicity while selectively enhancing therapy responses in cancer versus normal tissues.
Controlling your blood sugar levels helps you control your cravings, Dr. Burrows says. “When we are not on a sugar roller coaster from processed carbohydrates, most people make better food choices because they are not looking for their next hit of food,” she says. You may also find you’re able to go longer periods without eating, he says. Intermittent fasting is a common practice among dieters who’ve been eating keto for a while. Learn how one woman totally kicked her sugar habit by trying the keto diet.
Studies found that endurance performance, whether it was anaerobic or aerobic was impaired or maintained with a ketogenic diet. This is still a complicated area to study, since majority of studies used in this review had small sample sizes, no control group or were very short in duration (no more than six weeks). Because of this, it is still unclear whether endurance performance is enhanced or impaired with a ketogenic diet.
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.
To ensure you are getting enough potassium, include avocados and leafy greens like spinach in your daily diet. Sprinkle some unrefined salt on every meal and in your water to replenish your sodium levels as well. Some ketogenic dieters suggest getting at least 5 to 7 grams of salt per day (one teaspoon to a teaspoon and a half per day) during your first week on the ketogenic diet.
Slightly increase carbs. If you wait a few more weeks and still have trouble with the ketone smell, you might consider eating slightly more carbs to reduce the ketosis. Try increasing to between 50 and 70 grams per day. You might also try combining this with intermittent fasting, such as only eating within an 8-hour window, to maintain the benefits of ketosis without the side effect of fruity breath.
Weight loss often means feeling hungrier and fighting off more cravings, but that doesn’t always seem to be the case when you go keto. People report less hunger and a diminished desire to eat after adopting a ketogenic diet, according to an analysis of 26 studies. Experts don’t fully understand why, but it’s thought that very low carb diets could suppress the production of hunger hormones like ghrelin.
To avoid the overload of stress, I find my relief by being the person at the origin of my son’s quality of life. I am not a doctor, a pharmacist, or a research person. I am just Max’s mother. For almost 15 years I have been using food to treat the adverse side effects of his syndrome. Angelman Syndrome (AS) is one of many neurological disorders that can be treated with therapeutic diets.
High-protein ketogenic diet (HPKD): This version of the keto diet is often followed by folks who want to preserve their muscle mass like bodybuilders and older people. Rather than protein making up 20 percent of the diet, here it’s 30 percent. Meanwhile, fat goes down to 65 percent of the diet and carbs stay at 5 percent. (Caution: folks with kidney issues shouldn’t up their protein too much.)
I know it is hard when you have been taught something, and believed it, and taught it to others…only to be shown that what you have been taught is not the end all be all that you were led to believe. It sucks. But, you can choose to ignore the truth, and continue to follow the incorrect path. Or, you can look at the facts, and realize that what you have been taught is not the truth…and you can take a new path, which will lead many to wonderful new lives.
Those issues can be part of what's known as the “keto flu,” Warren says. Other side effects of the keto diet, all of which are tied to carb withdrawal, can include lightheadedness, nausea, mental fog, cramps, and headaches, in addition to tiredness. Luckily, the keto flu doesn't usually last more than a week—which is coincidentally about when people start to see the number on the scale go down, says Warren.
With the high intake of fat, are we concerned about the high intake of cholesterol? YEP. A study using the keto diet as a form of treatment for epileptic seizures in children found that after 6 months of administering the diet, triglyceride levels increased, total cholesterol levels increased, and HDL and LDL increased. These results suggest that over time, a keto diet may lead to an increased risk of hypercholesterolemia and hypertriglyceridemia. In the same ten-year study, 40% of patients developed hypertriglyceridemia and 29% of patients experienced hypercholesterolemia. So, if heart disease runs in your family, you may want to bow out now.
This is ALL so confusing and overwhelming. I am not diabetic. I am trying to be proactive about it. I am borderline obese (by US standards) and obese (by Asian standards). I am 50 years old. I was addicted to fat and sugar (especially combined!) through my teens and twenties. I decided to get healthy in my 30s, so I became a Vegan (but an unhealthy/careless one, so my weight yo-yo’ed a lot in my 20s and 30s). In my 40’s I reintroduced animal products into my diet and a number of my health issues went away, but I am still fat. I am considering Keto/Carnivore, but I am concerned that I may just be falling prey to more extreme diets which could set me up for problems (e.g. diabetes) down the road. I guess I am what most would refer to as pre-diabetic (metabolic syndrome). Should I try keto or am I taking too much of a risk?
Hi, I think Keto is a great starting point. I am almost 60 years old and finally feel good, no fogginess or sluggishness. For the first time I have no hippy handles and my tummy is flatter – no bloating or puffiness and I feel more energetic. I have only been doing Keto for about 4 weeks. I am so happy with the results!! I will continue for another 8 weeks or so then I will add more foods back in BUT moderation is key. I will slowly up my healthy carbs and find what is good for me. Happy days everyone!!! =)
Thanks for reading Roxanne! You could try the following: eating more frequently, using MCT oils, consuming plenty of salts, and potentially using an HPA axis supporting formula such as adapt-strong: https://store.drjockers.com/products/adapt-strong we also have an awesome magnesium lotion with melatonin that could be helpful in this case: https://store.drjockers.com/products/magnesium-lotion-goodnight-with-melatonin
In a survey of both children and adults, researchers found that a very low carbohydrate diet promotes “exceptional glycemic control” in those with type 1 diabetes mellitus. When it comes to type 2 diabetes, the Journal of American Medical Association recently published a review examining the effective use of the ketogenic diet in those with type 2 diabetes.
