Symptoms of the keto flu include headache, fatigue, dizziness, sleep problems, heart palpitations, cramps, and diarrhea. These side effects usually lessen and eventually resolve in about two weeks. (2) But to lessen the effects of any discomfort, simply consider slowly transitioning onto a ketogenic diet rather than rushing to change your eating habits. By slowly lowering your carbohydrate intake, while gradually increasing your intake of dietary fat over time, you can transition with less of a negative impact and potentially prevent the keto flu.
It seems strange that a diet that calls for more fat can raise “good” cholesterol and lower “bad” cholesterol, but ketogenic diets are linked to just that. It may be because the lower levels of insulin that result from these diets can stop your body from making more cholesterol. That means you’re less likely to have high blood pressure, hardened arteries, heart failure, and other heart conditions. 

As I understand intermittent fasting, the long period between my early dinner at 6 pm and breakfast at about 8:30 am qualifies. As a past yoga instructor, fasting was something that we were encouraged to do regularly as well as cleansing. I feel so frustrated and helpless at not being able to make any difference no matter what I’ve tried. I am very disciplined and cheating is not an option.
It feels like everyone is talking about the keto diet — the high-fat, low-carb eating plan that promises to turn your body into a fat-burning machine. For that reason, keto has surged in popularity over the past year as a lose-weight-fast strategy. Thank Hollywood A-listers and professional athletes like Halle Berry, Adriana Lima, and Tim Tebow who’ve publicly touted the diet’s benefits, from shedding weight to slowing down aging. Here’s everything you need to know about going keto — and how to do it the Bulletproof way.
Hi Melissa,I’ve been trying on my own to eliminate carbs and sugar from my diet for obvious health reasons and weight loss. I’ve been doing ok and have lost 30 lbs. Since Memorial Day. The more I research, however, I realize I really need to fully commit to Keto if I’m really to be successful in losing a total of 90 lbs. Your blog and recipes and advice are the first time anyone has really explained and encouraged. I’m starting tomorrow with the 3 day kickstart and am very much looking forward to following you for meal plans and menus. Thanks for making things understandable.
Wow – that’s a lot of dairy! I’m gluten and dairy free, but I’ll watch your recipes to see what I can use. The thing that concerns me about the dairy is that casein in cheese has a molecular structure similar to gluten, difficult for my system to break that down. I wouldn’t be surprised if others with gluten issues also have the same problem. I, too, had the impression that fat = bad… but boy, am I really enjoying salads more with real vinaigrette, homemade with healthy oils. I’ve been low carb and almost sugar free for about two years because of a gut issue. But, I want to get back to cutting out the sugar… so I’ll be eager to see what you share.
After initiation, the child regularly visits the hospital outpatient clinic where he or she is seen by the dietitian and neurologist, and various tests and examinations are performed. These are held every three months for the first year and then every six months thereafter. Infants under one year old are seen more frequently, with the initial visit held after just two to four weeks.[9] A period of minor adjustments is necessary to ensure consistent ketosis is maintained and to better adapt the meal plans to the patient. This fine-tuning is typically done over the telephone with the hospital dietitian[18] and includes changing the number of calories, altering the ketogenic ratio, or adding some MCT or coconut oils to a classic diet.[3] Urinary ketone levels are checked daily to detect whether ketosis has been achieved and to confirm that the patient is following the diet, though the level of ketones does not correlate with an anticonvulsant effect.[18] This is performed using ketone test strips containing nitroprusside, which change colour from buff-pink to maroon in the presence of acetoacetate (one of the three ketone bodies).[44]

You can have a completely smooth transition into ketosis, or…not. While your body is adapting to using ketones as your new fuel source, you may experience a range of uncomfortable short-term symptoms. These symptoms are referred to as “the keto flu.” Low-sodium levels are often to blame for symptoms keto flu, since the kidneys secrete more sodium when you’re in ketosis, says Volek. A few side effects:
The keto diet changes the way your body converts food into energy. Eating a lot of fat and very few carbs puts you in ketosis, a metabolic state where your body burns fat instead of carbs for fuel. When your body is unable to get glucose from carbs, your liver converts fatty acids from your diet into ketones, an alternative source of energy. Burning ketones in place of glucose reduces inflammation and spurs weight loss.[1] 
The ketogenic diet—also known as "keto"—has become the latest big thing in weight-loss plans, touted recently by celebs like Jenna Jameson, Mama June, and Halle Berry. The diet involves cutting way back on carbohydrates, to 50 grams a day or less, to help the body achieve a state of ketosis, in which it has to burn fat (rather than sugar) for energy.
“One of the best meal planning tips I’ve ever received is to structure breakfast and lunch so that you don’t have to think too much about it,” says Emily Bartlett, co-founder of Real Plans. “If you’re okay with repetition, it’s ideal to have a simple selection of recipes for breakfast—including some that can be taken on the go. For lunch, go ahead and use your leftovers with a fresh green salad, and be sure to include a dressing that you really love.”
Diarrhea can also be due to a lack of fiber in the diet, says Kizer, which can happen when someone cuts way back on carbs (like whole-grain bread and pasta) and doesn’t supplement with other fiber-rich foods, like vegetables. It can also be caused by an intolerance to dairy or artificial sweeteners—things you might be eating more of since switching to a high-fat, low-carb lifestyle.
A computer program such as KetoCalculator may be used to help generate recipes.[46] The meals often have four components: heavy whipping cream, a protein-rich food (typically meat), a fruit or vegetable and a fat such as butter, vegetable oil or mayonnaise. Only low-carbohydrate fruits and vegetables are allowed, which excludes bananas, potatoes, peas and corn. Suitable fruits are divided into two groups based on the amount of carbohydrate they contain, and vegetables are similarly divided into two groups. Foods within each of these four groups may be freely substituted to allow for variation without needing to recalculate portion sizes. For example, cooked broccoli, Brussels sprouts, cauliflower and green beans are all equivalent. Fresh, canned or frozen foods are equivalent, but raw and cooked vegetables differ, and processed foods are an additional complication. Parents are required to be precise when measuring food quantities on an electronic scale accurate to 1 g. The child must eat the whole meal and cannot have extra portions; any snacks must be incorporated into the meal plan. A small amount of MCT oil may be used to help with constipation or to increase ketosis.[36]
For athletes, research on the keto diet highlights potential improvements in athletic performance, especially when it comes to endurance activities. An article suggests ketogenic-type diets may allow endurance athletes to rely mostly on stored fat for energy during exercise rather than having to refuel with simple carbohydrates during endurance training and competition while additionally improving recovery times. (10)
The first signs of ketosis are known as the “keto flu” where headaches, brain fogginess, fatigue, and the like can really rile your body up. Make sure that you’re drinking plenty of waterand eating plenty of salt. The ketogenic diet is a natural diuretic and you’ll be peeing more than normal. Take into account that you’re peeing out electrolytes, and you can guess that you’ll be having a thumping headache in no time. Keeping your salt intake and water intake high enough is very important, allowing your body to re-hydrate and re-supply your electrolytes. Doing this will help with the headaches, if not get rid of them completely.
This doesn’t mean that you can never have some of your favorite foods again.  Once you get past the adaptation phase and you have tested that you are in Ketosis, you can start experimenting with Keto versions of the foods you don't want to give up. Here are a few simple Keto recipes to start with. If you're looking for ready-to-eat Keto-friendly options, check out Country Archer Meat Sticks, Cuvee Coffee and FBOMB nut butters.
Ha! Don’t even get me started Alisha! Mr. Hungry will eat whatever healthy low carb dinner I made and say it was delicious, then help himself to a pint of ice cream and eat THE WHOLE THING right in front of me! Now when I occassionally make low carb cookies or treats I let him have one and then it’s HANDS OFF because he can (and does) eat whatever he wants!
While it may be new to you, the keto diet has actually been around since the 1920’s, when the Mayo Clinic reported its effectiveness for helping epilepsy (that is still the case). Since then, there’s strong evidence that the keto diet helps with weight loss as well as type 2 diabetes, prediabetes, and metabolic syndrome, says Jeff Volek, Ph.D., RD, professor in the department of Human Sciences at The Ohio State University in Columbus, Ohio and co-author of The Art and Science of Low Carbohydrate Living.
Lastly, if you're active, you might need to make some adjustments to take that into account. "For the first one to two weeks, temporarily reducing your exercise load can be helpful as your body adjusts to being in ketosis," he says. "Additionally, for those who have an intense workout schedule, carb cycling may be a good option." Carb cycling essentially means you'll increase your carb intake on the days you're doing exercise, ideally just two to three days per week. "While low-carb days may be around 20 to 30 grams of net carbs daily, high-carb days can range all the way up to 100 grams, although it can vary based on your size and activity level," says Dr. Axe. (Related: 8 Things You Need to Know About Exercising on the Keto Diet.) 
It is possible to combine the results of several small studies to produce evidence that is stronger than that available from each study alone—a statistical method known as meta-analysis. One of four such analyses, conducted in 2006, looked at 19 studies on a total of 1,084 patients.[22] It concluded that a third achieved an excellent reduction in seizure frequency and half the patients achieved a good reduction.[3]

Started the kickstart yesterday and stuck to it all day. Was so easy and the dishes were good! I did bacon and eggs, tuna with Romaine, buffalo chicken…even made the mousse! I dont want to use bottled dressings so I made this one…. the BEST! https://lowcarbyum.com/creamy-blue-cheese-dressing/ I already hit ketosis this morning! I have been trying to cut down on carbs for the last month or more so maybe that’s why I hit it so quickly. Im excited to stick with this! Thank you for the recipes and the humor!
Keep up electrolytes. The major electrolytes in our bodies are sodium, potassium and magnesium. Because a low carb diet (especially a keto diet!) reduces the amount of water you store, this can flush out electrolytes and make you feel sick (called “keto flu”). This is temporary, but you can avoid or eliminate it by salting your food liberally, drinking broth (especially bone broth), and eating pickled vegetables. Some people also choose to take supplements for electrolytes, but it’s best to first consult a doctor that understands and supports keto/low carb lifestyles.
A systematic review in 2016 found and analysed seven randomized controlled trials of ketogenic diet in children and young people with epilepsy.[2] The trials were done among children and young people for whom drugs failed to control their seizures, and only one of the trials compared a group assigned to ketogenic diet with a group not assigned to one.[16] The other trials compared types of diets or ways of introducing them to make them more tolerable.[2] Nearly 40% of the children and young people had half or fewer seizures with the diet compared with the group not assigned to the diet. Only about 10% were still on the diet after a few years.[2] Adverse effects such as hunger and loss of energy in that trial were common, with about 30% experiencing constipation.[16]
Here are a few of the most common side effects that I come across when people first start keto. Frequently the issues relate to dehydration or lack of micronutrients (vitamins) in the body. Make sure that you’re drinking enough water (close to a gallon a day) and eating foods with good sources of micronutrients. To read more on micronutrients, click here >

Your body is going to be like an angry child having a tantrum – IT WANTS SUGAR AND CARBS NOW, but you aren’t going to give it any are you? ARE YOU??? Just like with children, the key is to distract, distract, distract (oooh shiny!). Give it something else desirable, (bacon, cheese, etc.) even if it isn’t what it really wants. Don’t give in thinking you’ll feel better if you just eat a little bit of carbs – there is no compromising!
The brain is composed of a network of neurons that transmit signals by propagating nerve impulses. The propagation of this impulse from one neuron to another is typically controlled by neurotransmitters, though there are also electrical pathways between some neurons. Neurotransmitters can inhibit impulse firing (primarily done by γ-aminobutyric acid, or GABA) or they can excite the neuron into firing (primarily done by glutamate). A neuron that releases inhibitory neurotransmitters from its terminals is called an inhibitory neuron, while one that releases excitatory neurotransmitters is an excitatory neuron. When the normal balance between inhibition and excitation is significantly disrupted in all or part of the brain, a seizure can occur. The GABA system is an important target for anticonvulsant drugs, since seizures may be discouraged by increasing GABA synthesis, decreasing its breakdown, or enhancing its effect on neurons.[7]

It seems strange that a diet that calls for more fat can raise “good” cholesterol and lower “bad” cholesterol, but ketogenic diets are linked to just that. It may be because the lower levels of insulin that result from these diets can stop your body from making more cholesterol. That means you’re less likely to have high blood pressure, hardened arteries, heart failure, and other heart conditions. 
The ketogenic diet is a high-fat, adequate-protein, low-carbohydrate diet that in medicine is used primarily to treat difficult-to-control (refractory) epilepsy in children. The diet forces the body to burn fats rather than carbohydrates. Normally, the carbohydrates contained in food are converted into glucose, which is then transported around the body and is particularly important in fueling brain function. However, if there is little carbohydrate in the diet, the liver converts fat into fatty acids and ketone bodies. The ketone bodies pass into the brain and replace glucose as an energy source. An elevated level of ketone bodies in the blood, a state known as ketosis, leads to a reduction in the frequency of epileptic seizures.[1] Almost half of children and young people with epilepsy who have tried some form of this diet saw the number of seizures drop by at least half, and the effect persists even after discontinuing the diet.[2] There is some evidence that adults with epilepsy may benefit from the diet, and that a less strict regimen, such as a modified Atkins diet, is similarly effective.[1] The most common adverse effect is constipation, affecting about 30% of patients—this was due to fluid restriction, which was once a feature of the diet, but this led to increased risk of kidney stones and is no longer considered beneficial.[2][3]

The ketone bodies are possibly anticonvulsant; in animal models, acetoacetate and acetone protect against seizures. The ketogenic diet results in adaptive changes to brain energy metabolism that increase the energy reserves; ketone bodies are a more efficient fuel than glucose, and the number of mitochondria is increased. This may help the neurons to remain stable in the face of increased energy demand during a seizure, and may confer a neuroprotective effect.[55]


I also have to tell you that you are HILARIOUS! I laughed so hard reading your lead up to the 3 day plan. Thank you for your guidance, honesty, outstanding sense of humor (we all need it), incredibly delicious recipes and your baffling organization. I truly don’t know how you get it all done. You make it “do-able” and fun. I’m actually excited to start!

okay so i am very new at this…starting this tomorrow with my mom. i know it says in the 3 day blog not to be concerned with portion size at first, but when that’s over with how do i know how much to eat? for instance, how many of the cream cheese pancakes are a normal portion size and how much ham and cheese am i supposed to put in them? sorry if any of these questions were answered previously, i just have read like every blog and i am confused.
Meat – Unprocessed meats are low carb and keto-friendly, and organic and grass-fed meat might be even healthier. But remember that keto is a high-fat diet, not high protein, so you don’t need huge amounts of meat. Excess protein (more than your body needs) is converted to glucose, making it harder to get into ketosis. A normal amount of meat is enough.
Question: I do not see portions indicated on the menus. If they are they, accept my apologies! For example, is the pancake recipe for one person/one meal? I hope so! Also, I’m looking at the buffalo wings. How many wings for one meal? I’m asking because, a. I might just eat them all, and b. I have a family of 4 and want to cook for everybody and need to plan accordingly.

Cauliflower is definitely my favorite low carb veggie Lora – it’s so versatile! But you can also enjoy loads of spinach, broccoli, swiss chard, zucchini, celery, eggplant, cucumbers, and even spaghetti squash! Kale, tomatoes, onions, garlic, mushrooms, even pumpkin in moderation. Potatoes are mostly a no no unless you are in maintenance mode and even then very sparingly!
Also, when you eliminate sugar and high-carb foods from your daily diet, "your body is able to heal itself and detox from the accumulated inflammation that it is constantly fighting," That means less brain fog, improved cognition and brain health. Consequently, the improved mental clarity makes it easier for you to make smart food choices, adds the nutritionist.
Thank you. Needed this. Going to try. Been doing almost this. However on good days. I eat much less food. W maybe 40 to 60 carbs tops. But cant lose anymore. And go up 6 down7 or 8. Back up. Need to go down. 12. This is my 5th time losing over 100lbs. My last time. Its been off for over a year. I know this works. But u r right. Ppl will hate it. But suck it up. It sucks. Ive done it.
Thank you Mellissa. I guess I need to set up a Reddit account. Several people have directed me there for Keto forums for one reason or another. I try not to let it get me down but I have been fluctuating really badly since I started this WOE and I have a feeling it has a lot to do with the hormones not being balanced. I came off of a prepackaged, doctor recommended food plan that really knocked me outta whack and helped me discover that I do indeed have an under-active thyroid, which I have known most of my life because I have always felt hormonally off balance and could never lose weight. It is also genetic in my family but doctors never listened to me and at most would run the basic blood test to appease me which always came back normal…which is common…and when they did, they would lecture me about losing weight and hand me a prescription for diet pills or give me info on some fad diet. Now I am trying to fix it with Keto and natural remedies. I feel better than I ever have in my life on the energy front and that was almost an instant feeling after switching to Keto. I hope I balance out soon because I am 35-40 lbs down since mid-May (depending on my fluctuation for the week) and have about 100+ to go. The frustrating part is I have now lost the same 3-5 lbs repeatedly over the past 5-6 weeks and all I can think is that could have been 20-30 lbs closer to my goal weight! I even considered going back on that nasty diet even though I felt terrible because I did lose consistently. I have confirmed my macros with some others who are more experienced and they are just as boggled as I am about the bad fluctuation.
We’re also going to keep it simple here. Most of the time, it’ll be salad and meat, slathered in high fat dressings and calling it a day. We don’t want to get too rowdy here. You can use leftover meat from previous nights or use easy accessible canned chicken/fish. If you do use canned meats, try to read the labels and get the one that uses the least (or no) additives!
There are vegetables that are high in carbs and others low in carbs. The keto diet recommends sticking to the ones low on carbs but encourages you to eat a lot of them. Best vegetables are all green ones to make it easy. And vegetables that grow above the ground (e.g. lettuce) are always better than the ones that grow below the ground (e.g. potatoes)
This week we’re getting stricter with our fasting. We had a full week of intermittent fasting and now we’re going to skip breakfast and lunch. Water is our BEST friend here! Don’t forget that you can drink coffee, tea, flavored water, and the like to get your liquids in. Keep drinking to make sure you’re not thinking about your stomach. It MIGHT start growling, just ignore it – your body will adjust with time.

okay so i am very new at this…starting this tomorrow with my mom. i know it says in the 3 day blog not to be concerned with portion size at first, but when that’s over with how do i know how much to eat? for instance, how many of the cream cheese pancakes are a normal portion size and how much ham and cheese am i supposed to put in them? sorry if any of these questions were answered previously, i just have read like every blog and i am confused.


So, I started the 3 day kick-start a week ago and am still following the plan! I went out and purchased the cookbook on Thursday and have been pouring over it since. Made the cauliflower mashed potatoes last night and they were awesome. A keeper for my household. Even hubby liked them. I feel great and am feeling the effects of weight loss and no carbs in my system…in a good way. Passed on the carb flu- probably because I had cut way down on the carbs before starting this. I dont miss them a bit…I keep thinking I should increase my carbs, LOL but I m not sure I want to ! Thank you for your book and thank you for your humor and thank you for your motivating spirit!
