After receiving Keto Comfort Foods as a gift from a friend that knew we were “doing Keto,” I was inspired to get this “how” and “why” book to get back on track. First, I just love the recipes in the Comfort Foods book—every one we’ve tried has been a big hit. So I’m planning to get more of her recipe books—they all look awesome! The “Dairy-Free” and “Restaurant Favorites” are next on my list.

Before you consume a BHB salt, these individual components are held together by ionic bonds. However, when you consume a supplement containing a BHB salt, it is absorbed into the blood where it dissociates into free sodium (Na+), potassium (K+), and finally, the actual ketone. This means that consuming a product containing a BHB directly and immediately puts ketones into your blood, without the need for you to eat tons of fats or engage in carbohydrate restriction or fasting to generate the ketones.
Start by grating your cauliflower, so it looks like cauliflower rice. Put it all in a bowl and squeeze out as much moisture as possible. This helps to pack everything together to make your bread slices. Make the cauliflower into patties and then pop onto a baking tray. Just put in the oven on a medium heat for around 15 minutes. They’ll be ready to go!
Ketosis occurs either as a result of increased fat oxidation, whilst fasting or following a strict ketosis diet plan (ENDOGENOUS ketosis), or after consuming a ketone supplement (EXOGENOUS ketosis). When in a state of ketosis the body can use ketones to provide a fuel for cellular respiration instead of its usual substrates: carbohydrate, fat or protein. 
actually sugar is bad for you and does cause diseases. yes the keto is dangerous and not meant to be a long term way of eating. If you read more about it , it’s for people that are really overweight that need to lose a lot of weight quickly. Humans are not meant to eat that much meat. If you go back to the biblical days, which is the way we should still be eating, they ate more vegetables and fruits than meat. Fish was the only meat Jesus ate. More people need to base their diets off alkaline foods because our bodies are acidic and we need to eat more alkaline foods to balance the acid in our bodies. Acidic bodies are more likely to get diseases. Meats, starches, sugars, sodas, etc are considered highly acidic so we should only be eating those foods on occasion not on a daily basis. Vegetables and fruits are what should be the majority of our diets. I have been eating more alkaline foods for the past 2 weeks or less and have already noticed a difference in my weight and energy . No one wants to talk about alkaline foods because the doctors wouldn’t make any money if people were well all the time because they took care of their bodies. They are not taught about nutrition nearly as much as they are medicines in school. It’s sad, but true. They only know how to medicate a problem which usually doesn’t help and can even make things worse. They should be learning about nutrition and teaching people what to eat and what not to eat to prevent diseases.
Then there’s medium chain triglycerides (MCT’s). Most dietary fat has to be converted into water soluble molecules that then need to enter the liver via your lymph system. Your liver then converts these molecules to fatty acids and ketone bodies. But unlike most other forms of dietary fats, MCT’s can enter your liver directly without having to go through your lymph system. This means that consuming MCT’s gives your body an opportunity to quickly produce ketone bodies.
The latest — or maybe just loudest — diet obsession transfixing the internet says it will help you lose weight, live longer, and improve your memory. Sounds great, you say? Except that these benefits will only bloom once you cut carbohydrates. Familiar story, right? The Atkins diet is back? We’re all gonna start eating eggs and bacon for every meal again until our cholesterol inevitably reaches code-red levels?
C8 is the rarest MCT found in coconut oil, comprising about 6% of coconut oil. It has potent anti-microbial properties (way more potent than lauric acid) to help you maintain a healthy gut, and it is the fastest MCT to metabolize in the brain. (hence the name Brain Octane). Your liver does not need to process C8, and it only takes the steps for your body to turn it into ATP cellular energy (sugar takes 26 steps). You would need 18 tablespoons of coconut oil to get just one tablespoon of Brain Octane.
No and yes. The liver can make ketones out of alcohol, so technically, when you drink you'll continue to produce ketones and so will remain in ketosis. The problem is ... alcohol converts more easily to ketones than fatty acids, so your liver will use the alcohol first, in preference to fat. Thus, when you drink, basically your FAT burning is put on hold until all the alcohol is out of your system.
Hi Ben…first, I have learned so much from you, thank you! I’m interested in using exogenous ketone supplements and I have a question for you. I just read the transcript of an interview Dave Asprey did with Dr. Richard Veech (episode 299). He advises against them, and says they can even be harmful. I was disappointed to read this, and wanted to ask you about it, since I respect your opinion greatly….thank you.
The keto diet is known for helping people lose a few pounds very quickly, says Becky Kerkenbush, RD, a clinical dietitian at Watertown Regional Medical Center. Carbs hold on to more water than protein or fat, so when you stop eating them, your body releases all that extra H2O by making you pee more. As a result, the scale might read a few pounds lower, and you may look a bit leaner.
Normal dietary fat contains mostly long-chain triglycerides (LCT). Medium-chain triglycerides are more ketogenic than LCTs because they generate more ketones per unit of energy when metabolised. Their use allows for a diet with a lower proportion of fat and a greater proportion of protein and carbohydrate,[3] leading to more food choices and larger portion sizes.[4] The original MCT diet developed by Peter Huttenlocher in the 1970s derived 60% of its calories from MCT oil.[15] Consuming that quantity of MCT oil caused abdominal cramps, diarrhoea and vomiting in some children. A figure of 45% is regarded as a balance between achieving good ketosis and minimising gastrointestinal complaints. The classical and modified MCT ketogenic diets are equally effective and differences in tolerability are not statistically significant.[9] The MCT diet is less popular in the United States; MCT oil is more expensive than other dietary fats and is not covered by insurance companies.[3]

I am not a doctor and this is not to be taken, interpreted or construed as medical advice. Please talk with a licensed medical professional about this. These are just my own personal thoughts and not a prescription or a diagnosis or any form of health care whatsoever. Your mother can avoid the "keto flu" by adding sufficient sodium to her diet and staying well hydrated, especially in the first few days of starting to reduce carbohydrates. The keto flu could also be called “carbohydrate withdrawal symptoms” because of the effects on hormonal and electrolyte balance. If you're not already using a device to measure ketones in your body, I recommend this one: https://bengreenfieldfitness.com/ketonix As far as how much to take, it all depends….you can actually do more than two servings per day if you want, and you can experiment to see how many servings your body should handle. You should know that it would be very difficult to overdose on ketones. They are water soluble, so any excess ketones will be eliminated mainly via the urine. Hope this helps!
"I always make an assessment of whether or not the cheat is worth it and 99 percent of the time, it’s not. If I do have a cheat meal, I don't worry about what the scale says afterward. I want to be happy with the decision before I make it, during it, and after I make it. A lot of it is living with your decisions and not beating yourself up over it."
This was a great article! Thanks so much for clarifying about the KETO diet. I am a thin woman who cannot really gain weight, even though I eat a pretty well rounded diet. My fiancé mentioned the KETO diet because he wants to lose weight. He also would like us to eat dinner together and eat the same things. The latter was mentioned before the KETO diet came into conversation. I already had misgivings about the KETO diet because I feel like my body needs carbs. I do not eat much meat at all and most of my protein comes from beans and other plant foods. Now, I KNOW that the KETO diet is not for me. I am already concerned with losing muscle mass due to aging and changing biologically through peri-menopause and not exercising as much as I should. I LOVE sweet potatoes and other foods you mentioned and could not see giving them up. Anyway, thanks for the information about your experience!
Check nutritionally-complete low-carb menus with under 50 grams of net carbohydrate per day to see what a ketogenic diet could look like. These menus are, however, going to be too high in protein for some people to remain in ketosis, and some of them may be a little high in carb if you have very poor carb tolerance. Keep in mind that ketogenic diets should always be tailored to the individual.
I’m glad I came across this post. One of my friends was advised to do Keto by her doctor due to insulin resistance and was talking about how much weight she has lost in a very short time period and I thought maybe it would be worthwhile to try myself for at least a jumpstart to weight loss. The more I read about the diet, the more concerned I was that eating that much fat would be detrimental to me because my cholesterol is slightly higher than normal, my family has a history of heart disease, and I had my gallbladder removed two years ago. It seems that after reading this post, my concerns may have been warranted. I’m glad to see something to balance out all of the positive press that keto seems to be receiving these days and give an alternate point of view. I’ll keep looking for a balanced diet that will work for me. Thank you.
Ben, great article! I recently did my own ketosis experiment and didn’t catch the 100-200g advise until later than I should have, I’m guessing. Great results for 1-2 months but after 3 months I quit sleeping through the night and would wake after about 4 hours of rest each night. My guess is that the extra carbs at night coupled with iodine supplements should allow me to “have my cake and eat it too?” Any other suggestions on the sleep issue? I’ve gone back to High Fat/Low Carb, have improved sleep but I do miss nutritional ketosis and want to try again once my sleep is stable. Thank YOU!!!
First reported in 2003, the idea of using a form of the Atkins diet to treat epilepsy came about after parents and patients discovered that the induction phase of the Atkins diet controlled seizures. The ketogenic diet team at Johns Hopkins Hospital modified the Atkins diet by removing the aim of achieving weight loss, extending the induction phase indefinitely, and specifically encouraging fat consumption. Compared with the ketogenic diet, the modified Atkins diet (MAD) places no limit on calories or protein, and the lower overall ketogenic ratio (approximately 1:1) does not need to be consistently maintained by all meals of the day. The MAD does not begin with a fast or with a stay in hospital and requires less dietitian support than the ketogenic diet. Carbohydrates are initially limited to 10 g per day in children or 20 g per day in adults, and are increased to 20–30 g per day after a month or so, depending on the effect on seizure control or tolerance of the restrictions. Like the ketogenic diet, the MAD requires vitamin and mineral supplements and children are carefully and periodically monitored at outpatient clinics.[47]
First, decide if you need to check ketones.  Amy Berger of Tuit Nutrition has a great post here to help you decide.  If, after reading that, you still want to check your ketone levels, there are several ways to check them. You can buy Bayer ketone stix, and check the levels of ketones in your urine. Or you can use a blood ketone meter.  The Precision Xtra has been the one to use until just recently. The problem is that this meter is hard to find, as the manufacturer Abbott keeps changing the name. The strips are even harder to find and buy.
This is why Gaspari Nutrition chose highly branched cluster dextrin for what we consider to be the gold standard of recovery and performance drinks. This high molecular weight carbohydrate has a special helical structure, which gives it unique properties unlike many of the corn starches or polysaccharides out there. I'll be real with you and say this stuff isn’t cheap, but you certainly pay for what you get, and highly branched cluster dextrin is unlike any carb source I've found – especially if you want to control blood sugar levels and gut issues.
Ketone esters: These are the raw ketones (in this case, beta-hydroxybutryate) that are not bound to any other compound. These exogenous ketones can be utilized quicker and potentially have a better effect at raising blood ketone levels as your body doesn’t have to cleave the BHB from any other compound. The downside? They typically have a foul taste and can cause an upset stomach.
The SS providing information to the brain mainly send information to the nucleus of the solitary tract (NTS). These signals are generated in the GIT and abdominal viscera, as well as in the oral cavity and provide information about mechanical and chemical properties of food. The information is transmitted via vagal and spinal nerve to the NTS. The ASs arrive to the median eminence through ARC or through the blood-brain barrier (BBB). All these afferents are integrated in a complex and not fully understood network.
You’ve heard this proclamation even before starting keto diet: You need plenty of water each day for your health. That’s especially true with the keto diet. Without carbs, your body won’t store as much water. Anything you drink passes right through—you can expect to urinate frequently. “Starchy foods have more water retention,” Dr. Marvasti says. “When you avoid these types of foods, you need to make sure you are compensating by drinking enough water.” These 7 clever ways to stay hydrated can help.
In the US especially, coconut oil and MCT oil manufacturers are legally allowed to claim that lauric acid is an MCT because chemists named it that way, even though it does not act like other true biological MCT oils. If you are relying on plain coconut oil or “MCT-labeled” oil to get enough useful MCTs, think again and check the label: odds are you’re getting very few of the potent, ketogenic shorter chain MCTs (also known as “C8” and “C10”), and instead getting mostly cheaper but ineffective lauric acid.

Depending on how you choose your fats, the keto diet can contain an abundance of saturated fat, which raises levels of dangerous LDL cholesterol and causes atherosclerosis, the buildup of fats and cholesterol in the arteries. If you decide to go keto, have a doctor monitor your cholesterol levels monthly to ensure you remain within a healthy range.

You could pick any of the countless diet books on the market, follow their plan to the last calorie, and lose weight. This is because — as study after study has shown — calories and dietary adherence matter more than anything for weight loss. You can gain or lose weight on any combination of foods. People have lost weight on twinkies, McDonalds, juice, plants, and obscene amounts of meat.


Sometimes it does get hard, sometimes you may want to cheat, and sometimes you do. I've done it. But remember your end goal - for me that is around 30 pounds to go, for you it may be to get stronger, or lose X amount of weight, etc., and get back on the horse if you fall down! Get back up and OWN IT because we are all building a better life for ourselves! YOU GOT THIS! WE GOT THIS!
Adipose tissue can be used to store fatty acids for regulating temperature and energy.[21] These fatty acids can be released by adipokine signaling of high glucagon and epinephrine levels, which inversely corresponds to low insulin levels. High glucagon and low insulin correspond to times of fasting or to times when blood glucose levels are low.[23] Fatty acids must be metabolized in mitochondria in order to produce energy, but free fatty acids cannot penetrate biological membranes due to their negative electrical charge. So coenzyme A is bound to the fatty acid to produce acyl-CoA, which is able to enter the mitochondria.
Hi Ben – Great article. I had trouble at the end figuring out if you were now eating high fat (60-80% of calories), or if you went back to something closer to 50% fat calories and higher carbs and are using exogenous ketones to get int ketosis when needed. Are you doing any carbs at night or a refeed, or just having higher carbs on most days? Thanks
After reading the article I shopped around and I noticed there are types of MCT oil that are derived from Palm Oil and are considerably less expensive. (http://prototypenutrition.com/keto8.html ) There is a litany of research that says that Palm Oil is on the same level a High Fructose Corn Syrup when it comes to your body. Is this true for MCT oil made from Palm Oil? Is Coconut derived superior to Palm Oil or a blend of the two?
I enjoyed this article. My whole family has been on keto for a few months now. My husband started earlier that we did. We all enjoy this way of eating. But I do believe that Keto is not for everyone. I have type 2 diabetes and my doc actually recommends this way of eating and she also practices it. We are not strict and we have all lost weight and are feeling better. But with that being said if I want to eat a few French fries or take a bit of my bun from my burger I do. And when my daughters bday comes up soon I will have cake and I’m gonna eat a piece and enjoy every bite.
An increase in fat burning ability could decrease the efficiency of exercise: one adaptation to a high fat diet is an increase in a process called mitochondrial uncoupling. This means that some of the stored energy from metabolic substrates is not used to generate ATP but is ‘dissipated’ leading to a decrease in efficiency of energy production 26 ,19.  
On the ketogenic diet I feel very shaky/anxious from when I wake up til about noon. Eating doesn’t really help. It could be electrolyte related but seems possibly more related to excess cortisol/adrenaline as noon is also when I start to crash and get tired on a more normal diet, and because those 3 am awakenings that worsen simultaneously in ketosis seem to also have to do with HPA axis stuff. Does this side effect potentially also have to do with my fasting blood sugar being elevated?
I know, I know you’d think with all these side effects I’d just give up on ketosis! but I enjoy the mental clarity and I have a lot of food sensitivities and gut and yeast problems and don’t tolerate carbs well either so I feel stuck between a rock and a hard place. Not craving what I can’t have constantly is LIFE CHANGING! (34 year old female with chronic fatigue, thin, hike for exercise).

By now, you’ve likely heard about the ketogenic diet, the trendy weight-loss plan that calls for dramatically reducing how many carbs you eat, moderating your protein, and upping your fat intake. As a result of following the ketogenic diet, or keto for short, for a few days, your body will enter ketosis, a state that some research links to weight loss, better glucose control, and improved cholesterol. Not all health experts would recommend the diet, though, as it can lead to kidney stones, increased intake of “bad” fats, nutrient deficiencies, decreased bone density, and stomach problems, various research suggests.
As with any serious medical therapy, the ketogenic diet may have complications.[27] These are generally less severe and less frequent than with anticonvulsant medication or surgery.[27] Common but easily treatable short-term side effects include constipation, low-grade acidosis and hypoglycaemia if there is an initial fast. Raised levels of lipids in the blood affect up to 60% of children[37] and cholesterol levels may increase by around 30%.[27] This can be treated by changes to the fat content of the diet, such as from saturated fats towards polyunsaturated fats, and, if persistent, by lowering the ketogenic ratio.[37] Supplements are necessary to counter the dietary deficiency of many micronutrients.[3]
Hello, I have a quick question. I’ve been on keto since March 2017. Already lost about 45 pounds, down to 140 at 5’7 and about 16.4% fat. I take a magnésium cap each morning to be sure I got enough and eat at least 1 serving of baby spinach a day with olive oil or fatty dressing that have no carbs. My last meal is always between 5 and 9 pm (mostly around 6) and I don’t eat back before 12pm the next day on week days and not before next dîner on week end. Fasting isn’t something new to me and when I read it help getting in ketosis I continued.
The gut-brain link is important not only for the hormones produced by the gut, but also for the long-term body weight regulation. Studies in mice indicate that the gut microbiome influences both sides of the energy balance by contributing to nutrient absorption and regulating host genes that affect adiposity [however there are conflicting reports (Parks et al., 2013; Schele et al., 2013)]. However, it remains uncertain just how important gut microbiota are for nutrient absorption in humans. A cohort study has demonstrated that the nutrient load is a key variable that can influence the gut/fecal bacterial content over short time frames. Furthermore, the observed associations between gut microbes and nutrient absorption indicates a possible role of the human gut microbiota in the regulation of the nutrient intake and utilization (Jumpertz et al., 2011).

I would do breath ketone measurements. That's exactly what I do and this is what I use :https://greenfieldfitnesssystems.com/product/ketonix-breath-ketone-monitor/
Ketosis is a metabolic state where most of the body's energy supply comes from ketone bodies in the blood, in contrast to a state of glycolysis where blood glucose provides most of the energy. Ketosis is characterized by serum blood concentrations of ketone bodies over 0.5 millimolar with low and stable levels of insulin and blood glucose. However, with ketone supplementation (as you’ll learn about later in this article) ketosis can actually be induced even when there are high levels of blood glucose.

Body by Butter (or maybe Abs by Avocado ?) After my 2-week #Keto360 experience with @drjoshaxe I can officially say that I'm both satisfied with the results (I don't usually make a habit of kissing my bicep like a ) and craving a bagel. #sorry #jkallhealthyfats #keto #ketogenicdiet // Thank you @tatiboncompagni for the #sculptologie lesson this a.m. and @mariettaalessi for the .
As ketones are the only other metabolic substrate that can fuel the brain, there is a compelling mechanism whereby ketosis could improve brain energy metabolism and therefore improve symptoms of AD. Despite a declining ability of the brain to use glucose, cerebral ketone metabolism is preserved in AD (Castellano2015). This means that ketosis could be used to prevent an energy deficit in the brain. Another possibility is that ketone metabolism decreases mitochondrial damage caused by oxidative stress in the brain52. Individuals with AD tend to have increased mitochondrial oxidative stress, which can worsen brain energy production and increase plaque and tangle formation53.

Getting adequate amounts of vitamins is extremely important to support healthy weight loss and overall wellness. Taking a multivitamin with synthetic ingredients has been shown to be ineffective and a complete waste of money[*]. Alternatively, consuming a high-quality greens powder made from real, nutritious whole foods rich in vitamins, minerals, antioxidants, fiber and phytonutrients is a much better way to optimize health and longevity. Check out this article for more information on supplementing with a high quality, effective greens powder.
