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.
"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.
Well, I managed to get to the store and get a few things to fire up this kickstart. I made the pudding today and it was a bit tangy so I decided to turn it into the Mousse instead. It was awesome and even though this is officially the 2nd day, I was ready for something chocolaty. I happened to have Hershey’s cocoa powder on hand, but I was wondering what “premium” powder you normally use? I have more questions building up, but I have not read the above questions yet. You may have answered them. This was more to tell you how much I liked the Mousse. I tried tofu mousse once and it was an epic fail!

Thank you soooo much for this. I have been a big fan of your recipes for a few months-delicious! I was floundering on my low carb for a while and this holiday season was the first in years that I just ate everything…whatever I wanted. I was left feeling huge, bloated, uncomfortable in my own skin. I had forgotten what I loved about low carb, that it wasn’t complicated and I did get to eat what I loved. Thank you again for reminding that it can be easy and delicious.
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?
If you talk to keto aficionados, you’ll find many save leftovers from dinner for the next day’s lunch. Cook once, eat twice—your keto diet menu for lunch is solved. If you don’t like leftovers or if you’re craving something different for lunch, the mid-day meal can be as simple as a scoop of chicken salad. Or, hit the salad bar at a local grocery store and top a bowl of greens with some good-fat goodies. You can also try one of these simple keto lunches:

Hi. Loved the article. I ran across this article when I found your pancake recipe. I am going on a cruise in 18 days. I started eating a high cal low carb diet a couple of days ago and noticed how similar it was to the Keto diet. So I said why not since I’m already kind of doing that. Then, I saw that you mentioned unusual periods and I am extremely worried that if I start the keto diet today, I might have my period while on my cruise and that is not going to be fun. What are your thoughts?
I have a question on sugar since I see it’s not allowed. Is splenda or any other sugar subsitute ok? What if one of the ingredients that is required for a keto recipe contains sugar, does it matter? I haven’t really seen any discussion on how some things may already contain sugar (even if in low doses) may affect the keto diet. Should they be avoided altogether?
When it comes to weight loss — a big possible draw of the plan for many individuals — the benefits of the ketogenic diet may not be much different from any other diet plan. “There is no magical weight loss benefit that can be achieved from this diet,” says Spano. “The ketogenic diet may help weight loss in the same way other diets help — by restricting food choices so you eat fewer calories.”
The easiest macro to calculate in the ketogenic diet is fat. Once you've got your carbs and protein set, simply fill the rest of your daily calorie needs with fat sources. If you find yourself wanting to gain a bit of weight, add approximately 500 calories, or 55 grams. If you want to lose weight, cut down on your fat intake by 200-500 calories, or 22-55 grams.
But it’s worth noting that, as yet, there hasn’t been enough research into the ketogenic diet to support its use in some medical conditions – so people using the diet to treat diabetes or polycystic ovarian syndrome, should consult their doctor before trying it, as it can affect blood sugar levels. People with pancreatic or liver problems, or problems with fat metabolism should also avoid the ketogenic diet. This is because the diet is so high in fat that it puts added pressure on both organs, which are essential for fat metabolism .
"I recommend only 5 percent of calories coming from carbs, which usually averages out to less than 30 grams," he says. "I understand why people get nervous and panic, thinking 'Can I even eat a salad?' This is why I recommend tracking only 'net carbs', which are total carbs minus fiber. For example, an avocado has 12 grams of carbs but 10 grams of fiber, which means it has 2 grams of net carbs. Also, green leafy vegetables are very nutritious and contain a lot of fiber, so you can almost eat them as much as you want and stay below your limit.
Hello. I’m a kept newbie. Started 6 days ago today. By day 4 I was down 10lbs. I’m following the 20 or less carbs a day, altho I more like less than 10 on most days. I have only wanted to harm someone for a cookie twice, and my bf for his fried potatoes once. I’m honestly shocked at how much food I really can eat with no carbs. And then on some days, shocked at how many carbs are in other things. Headaches and lack of energy are the only thing that I find bothersome, but i am pushing thru it. Thank u for a very detailed site. It’s helped me, and a coworker.

Hi Mellissa! A big huge THANK YOU for making this transition an easy one! Today was my day 4 so I weighed this morning after following the three day kick start and I am down exactly 5 pounds. I understand that this is usually water weight, but who cares! I used the KetoStix today and am officially in KETO! I really appreciate all of the hard work you have put into this. The recipes are simple and delicious. I am beyond excited to continue this journey…45 pounds to go! Thank you, Thank you, Thank you!!!
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.
Net carbs is simply total carbs minus fiber and non-digestible sugar alcohols, like erythritol. (This doesn’t apply to high glycemic sugar alcohols, like maltitol.) We don’t have to count fiber and certain sugar alcohols in net carbs, because they either don’t get broken down by our bodies, are not absorbed, or are absorbed but not metabolized. (Read more about sugar alcohols here.)
The popular low-carb diets (such as Atkins or Paleo) modify a true keto diet. But they come with the same risks if you overdo it on fats and proteins and lay off the carbs. So why do people follow the diets? "They're everywhere, and people hear anecdotally that they work," McManus says. Theories about short-term low-carb diet success include lower appetite because fat burns slower than carbs. "But again, we don't know about the long term," she says. "And eating a restrictive diet, no matter what the plan, is difficult to sustain. Once you resume a normal diet, the weight will likely return."

Ketogenic diets are, however, a well-established way to help control Type 2 diabetes, and the plan has for nearly 100 years been used to reduce instances of childhood epileptic seizures. Some scientists also think the high-fat diet may hold promise for staving off Alzheimer's, and there are some early indications it might help improve certain cancer treatment outcomes when used in conjunction with drugs. (Harper is part of a research team investigating how the diet might help boost treatment among people with breast cancer.)
You've likely heard horror stories of what competitors feel like when they cut carbs low, or when the average bro talks about going keto. However, the odds are that those people were not actually in nutritional ketosis, or more importantly, following a well-formulated ketogenic diet. Yes, you may experience some fogginess and discomfort, but it doesn't have to be intense if you handle it right.
Wilder's colleague, paediatrician Mynie Gustav Peterman, later formulated the classic diet, with a ratio of one gram of protein per kilogram of body weight in children, 10–15 g of carbohydrate per day, and the remainder of calories from fat. Peterman's work in the 1920s established the techniques for induction and maintenance of the diet. Peterman documented positive effects (improved alertness, behaviour and sleep) and adverse effects (nausea and vomiting due to excess ketosis). The diet proved to be very successful in children: Peterman reported in 1925 that 95% of 37 young patients had improved seizure control on the diet and 60% became seizure-free. By 1930, the diet had also been studied in 100 teenagers and adults. Clifford Joseph Barborka, Sr., also from the Mayo Clinic, reported that 56% of those older patients improved on the diet and 12% became seizure-free. Although the adult results are similar to modern studies of children, they did not compare as well to contemporary studies. Barborka concluded that adults were least likely to benefit from the diet, and the use of the ketogenic diet in adults was not studied again until 1999.[10][14]
The ketogenic diet is based on the principle that by depleting the body of carbohydrates, which are its primary source of energy, you can force the body to burn fat for fuel, thereby maximizing weight loss. When you consume foods that contain carbohydrates, the body converts those carbohydrates into glucose, or blood sugar, which it then uses for energy. (1)
The classic ketogenic diet is not a balanced diet and only contains tiny portions of fresh fruit and vegetables, fortified cereals and calcium-rich foods. In particular, the B vitamins, calcium and vitamin D must be artificially supplemented. This is achieved by taking two sugar-free supplements designed for the patient's age: a multivitamin with minerals and calcium with vitamin D.[3] A typical day of food for a child on a 4:1 ratio, 1,500 kcal (6,300 kJ) ketogenic diet comprises:[27]
Anticonvulsants suppress epileptic seizures, but they neither cure nor prevent the development of seizure susceptibility. The development of epilepsy (epileptogenesis) is a process that is poorly understood. A few anticonvulsants (valproate, levetiracetam and benzodiazepines) have shown antiepileptogenic properties in animal models of epileptogenesis. However, no anticonvulsant has ever achieved this in a clinical trial in humans. The ketogenic diet has been found to have antiepileptogenic properties in rats.[55]
About 20% of children on the ketogenic diet achieve freedom from seizures, and many are able to reduce the use of anticonvulsant drugs or eliminate them altogether.[3] Commonly, at around two years on the diet, or after six months of being seizure-free, the diet may be gradually discontinued over two or three months. This is done by lowering the ketogenic ratio until urinary ketosis is no longer detected, and then lifting all calorie restrictions.[45] This timing and method of discontinuation mimics that of anticonvulsant drug therapy in children, where the child has become seizure free. When the diet is required to treat certain metabolic diseases, the duration will be longer. The total diet duration is up to the treating ketogenic diet team and parents; durations up to 12 years have been studied and found beneficial.[9]
UPDATE: Hi! It’s been 4 weeks already. I am still cooking keto and enjoying many delicious dessert too! I have finally convinced my husband to totally convert to keto food. It’s only been one week since he stopped using diet package food. He is very happy with the food he get to eat and still losing weight but much slower pace this week. That’s because I have been giving him larger portions as this is the first week for him. Since he was already on low carb diet prior to this, keto flue may be not as bad but still want to keep him happy and better transition experience. Meanwhile, I get to cook keto for the whole family and really enjoying the new way of eating and cooking. I have lost total of 6 lb but that was enough to prove to my husband eating bacon and butter is ok as long as we are on keto diet. I was only doing this to convert my husband since he doesn’t have any interest in nutrition or theory behind it, so what he sees is what he believes. 6 lb may not sounds a lot for 4 weeks but I was already below average weight , so it was a lot of loss for me. I think it’s a science 5-30-65 combination works on everyone. Now I just eat more portions of everything ,so we can still eat same food. Today, he had a once a week appointment with his ideal protein dietitian. Seems like they are not convinced that he can still continue to lose weight unless he eat their packaged food. I plan to continue sending him there for once a week appointment , so he sill have something to be accountable for. Next few weeks, I’m hoping he won’t be as hungry so I can start portion control his food without his knowledge, LOL.

Check the nutrition labels on all your products to see if they’re high in carbs. There are hidden carbs in the unlikeliest of places (like ketchup and canned soups). Try to avoid buying products with dozens of incomprehensible ingredients. Less is usually healthier.Always check the serving sizes against the carb counts. Manufacturers can sometimes recommend inconceivably small serving sizes to seemingly reduce calorie and carb numbers.


I get many questions about intermittent fasting, the health benefits, the weight loss benefits, and the like. People normally use intermittent fasting for both the energy and mental clarity it can offer. But it’s not just good for that. It can offer breakthroughs of plateaus and even benefits in nutrient uptake in exercise. We go more in depth to intermittent fasting in Week 3 and 4, so keep your eyes peeled!

My cousin and his family have been eating this way for a few months and are quite inspiring. I would love to start this, but I am breastfeeding my six month old and plan to continue breastfeeding for at least another six months. Is this way of eating healthy for a breastfeeding mama? If it is, should I expect the same withdrawal symptoms to happen to my baby?

Just this week, a 25,000-person study presented at the European Society of Cardiology Congress in Munich suggested that people on the lowest-carb diets had the highest risk of dying from cancer, cardiovascular conditions, and all other causes. Another study, published this month in the Lancet, also found that people who followed diets that were low in carbs and high in animal proteins had a higher risk of early death compared to those who consumed carbs in moderation. (The opposite was true, however, for low-carb dieters who opted for plant-based proteins over meat and dairy.)

The ketogenic diet is calculated by a dietitian for each child. Age, weight, activity levels, culture and food preferences all affect the meal plan. First, the energy requirements are set at 80–90% of the recommended daily amounts (RDA) for the child's age (the high-fat diet requires less energy to process than a typical high-carbohydrate diet). Highly active children or those with muscle spasticity require more calories than this; immobile children require less. The ketogenic ratio of the diet compares the weight of fat to the combined weight of carbohydrate and protein. This is typically 4:1, but children who are younger than 18 months, older than 12 years, or who are obese may be started on a 3:1 ratio. Fat is energy-rich, with 9 kcal/g (38 kJ/g) compared to 4 kcal/g (17 kJ/g) for carbohydrate or protein, so portions on the ketogenic diet are smaller than normal. The quantity of fat in the diet can be calculated from the overall energy requirements and the chosen ketogenic ratio. Next, the protein levels are set to allow for growth and body maintenance, and are around 1 g protein for each kg of body weight. Lastly, the amount of carbohydrate is set according to what allowance is left while maintaining the chosen ratio. Any carbohydrate in medications or supplements must be subtracted from this allowance. The total daily amount of fat, protein and carbohydrate is then evenly divided across the meals.[36]

A keto diet has shown to improve triglyceride levels and cholesterol levels most associated with arterial buildup. More specifically low-carb, high-fat diets show a dramatic increase in HDL and decrease in LDL particle concentration compared to low-fat diets.3A study in the long-term effects of a ketogenic diet shows a significant reduction in cholesterol levels, body weight, and blood glucose.

Bonnie J. Brehm, Randy J. Seeley, Stephen R. Daniels, and David A. D’Alessio, “A Randomized Trial Comparing a Very Low Carbohydrate Diet and a Calorie-Restricted Low Fat Diet on Body Weight and Cardiovascular Risk Factors in Healthy Women,” The Journal of Clinical Endocrinology & Metabolism: Vol 88, No 4; January 14, 2009. http://press.endocrine.org/doi/full/10.1210/jc.2002-021480.
The ketogenic diet tries to bring carbohydrates down to less than 5 percent of a person’s daily caloric intake – which means eliminating most grains, fruit, starchy vegetables, legumes and sweets. Instead, it replaces those calories with fat. That fat is turned into ketone bodies, which are an alternative energy source: besides glucose derived from carbohydrates, ketones from fat are the only fuel the brain can use.

Positive science on ketosis coupled with personal successes passed by word-of-mouth have driven more people to explore the ketogenic diet, says Volek. More recently, the keto diet hints at having a promising therapeutic role in cancer, Alzheimer’s, Parkinson’s and polycystic ovary syndrome (PCOS). Research is still early in many areas, but Volek suspects there will more definitive answers on the wider scope of the diet’s benefits within the next decade.


Hi Melissa! I’m a female, 6 feet, 2 inches tall and I need to lose about 45 to 50 pounds…SO glad I found your website…it’s nothing short of amazing! I’m on day one of the Keto Kickstart and my question is, do the serving sizes apply to everyone’s size, BMI, height, etc.? I am a bit nervous of taking in too few calories. I plugged in my stats for the Keto calculator and I wonder if I can have larger portions of some of your recipes. Thank you for the beautiful recipes and menu plans!!!

when progress stalls there are three things to consider. 1: You can try to ride it out. Your body might be making some “behind the scenes” adjustments and once these are done you will start to loose again. 2: You will have to change either the intensity or the length of your exercise sessions. 3: In addition, you might have to tighten up on your calories. Have You been tracking your calories?…

You’ll need to eat plenty of avocado, coconut, olive oil, beef, chicken, low starch veggies, etc. Strict Paleo avoids both dairy and soy products – I’d start there and eliminate some of the carbs they allow and you should find plenty of recipes you can use for ketosis. Also try the Whole 30 which isn’t keto but eliminates dairy, soy and a few other common allergens and I lose weight on it every time even when I’m not in ketosis. Hope that helps and that you find something that works for you!


No deep fryers or air fryers needed for these wings! Forget those greasy chicken wings you’d order at a restaurant and opt-in for these homemade guiltless garlic parmesan wings. You won’t find rancid vegetable oil, gluten or a deep frier here — just avocado oil, healthy pecorino romano and free-range, organic chicken for a twist on an otherwise unhealthy classic.


For breakfast, we are going to change it up a bit. Here’s where we introduce ketoproof coffee. Now, don’t get me wrong – I know some of you won’t like it. If you’re not a fan of coffee, then try it with tea. If you’re not a fan of the taste (which is very rare), then try making a mixture of the ingredients by themselves and eating it like that. So, why ketoproof coffee?
Thanks so much Kelly! Not sure what the Atkins intro is, but I’m sure they have their reasons! Maybe if it’s slower it’s to ease the detox symptoms that cause some people to quit and then figure it’s better to ease into it. Personally I’m about ripping off the bandaid and getting it over with, ya know? So glad you and your husband are on board – keep us posted on your progress!!!
So you've decided you want to try out the high-fat, low-carb diet, better-known as the fat-burning ketogenic diet. Whether it's to lose weight, have more energy, or fuel workouts differently, going keto is a popular choice right now. But figuring out a keto meal plan on your own is no easy feat, especially since eating a diet super high in fats doesn't come naturally to many people who are accustomed to the traditionally carb-heavy American diet. (It's especially hard if you're vegan and want to try keto.) But this should help: Keto experts explain how to set yourself up for success, plus provide ideas for exactly what keto foods to eat when you're first getting started. (While you're at it, check out these Low-Carb Keto drinks That Will Keep You in Ketosis.)

I am a type 1 diabetic of 57 years. I am my doctor’s only patient that has had this disease this long with no diabetic problems. My A1C average is 7.0. My experience with eating a Keto diet is my blood glucose goes very high when eating more fat. I got no help from doctor, so I learned by trial and error to take more insulin for the among of fat I eat. I have it down to a percentage. If eating 6 carbs for breakfast and 18g of fat, I divide 30% into the 18g of fat, which will be 6. I add the 6 with the 6 carbs and I take 12 units of insulin for my breakfast. Not only do we need to take insulin for the carbs we eat, but also for the fat when eating the amount you should consume on a Keto diet. I have been using My Fitness Pal for 9 years to document everything I eat, keeping up with the total calories, carbs, fat, sodium, protein and sugar.
The modified Atkins diet reduces seizure frequency by more than 50% in 43% of patients who try it and by more than 90% in 27% of patients.[3] Few adverse effects have been reported, though cholesterol is increased and the diet has not been studied long term.[47] Although based on a smaller data set (126 adults and children from 11 studies over five centres), these results from 2009 compare favourably with the traditional ketogenic diet.[3]

Thank you for your reply! I kinda thought that was the case, just wanted to double check. I found a site that may make our lives even easier! You paste the recipe, enter the original recipe serving size, then enter how many servings you need and then convert! Check out this site http://mykitchencalculator.com/recipeconverter.html . Super helpful! Got the groceries, now wish me luck! Eek, I’m so excited. Thanks again so much.
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.

Well, I managed to get to the store and get a few things to fire up this kickstart. I made the pudding today and it was a bit tangy so I decided to turn it into the Mousse instead.

You’re so welcome Jessica – you and me both! I’m looking forward to feeling good again and having my clothes fit right will be nice too! ha ha! Thanks to all of your feedback I’ll be posting 7 day menu plans every Saturday, and we’ll all hopefully be reporting our pounds lost so far progress in the comments. I’m so looking forward to it – hope you’ll join us!!!

Thank you! Yea, no bread/pasta for me, by all accounts I was eating a (what I thought and what everyone would tell me, even a dietician I went to!) ‘healthy’ diet of whole grains, rice, fruit, vegetables, low fat, etc. and couldn’t understand why I was steadily gaining weight. That’s what led me here, as I was getting so frustrated and the more I read up on low carb/ketosis and how the body processes even conventionally healthy foods, it made sense to me, but I don’t think I can give up oatmeal and fruit forever! So I will definitely just make sure I only eat those in small amounts, but that is much farther down the road anyway.. I’m on to Week 1 and I’ll post an update at the end of the week. Thanks again!
I have been a long time viewer but have been drowning in graduate studies, needless to say I fully fell off the wagon! Well May 17th graduation is almost here time to get back on the wagon! I was soooo happy that you have Keto Meal Plans!! Did you have any recipes for a Keto Smoothie that meets the Keto LCHF requirements for the mornings I have to get the kids off to school & run out the door. A lot of great smoothies on the web but they usually include fruit which significantly increases the carbs… Any suggestions would be greatly appreciated.
Just like when you were on the birth control, keto messes with your hormones at first – but in a good way, as it’s regulating them. Stay the course and it should even out in a month or two. I had a month like yours and it felt like shark week lasted the entire time, but it eventually stopped. Here’s a link to some discussions on keto and shark week over on reddit that might help ease your mind! http://www.reddit.com/r/xxketo/search?q=shark+week&restrict_sr=on

For endurance athletes, the transition to a ketogenic diet may reduce recovery time after training, but for casual exercisers, the transition to the ketogenic diet may make sticking with your fitness routine a challenge at first. (10) If you feel your energy levels drop too much when starting the ketogenic diet, slow down your reduction of carbohydrates, making sure to do it over time rather than all at once.
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.
Achieving ketosis is a pretty straightforward, but it can seem complicated and confusing with all of the information out there.4If you want to learn more about ketosis and the scientific process around it, you can visit a very in-depth discussion about on Dr. Peter Attia’s website. Here’s the bottom line on what you need to do, ordered in levels of importance:
