Fairly recently, the diet was introduced as a weight-loss diet by an Italian professor of surgery, Dr. Gianfranco Cappello of Sapienza University in Rome. In his 2012 study, about 19,000 dieters received a high-fat liquid diet via a feeding tube inserted down the nose. The study showed an average weight loss of more than 20 pounds in participants, most of whom kept it off for at least a year. The researchers reported a few minor side effects, like fatigue.


The good news is that snacks are totally allowed (and I're not just talking about carrot sticks.) There are plenty of packaged options out there designed for keto fans. FATBAR is one of them. These snack bars have 200 calories, 16 grams of fat, and four grams of net carbs. They're also plant-based and are made with almond or cashew butter, cocoa butter, coconut, pea protein, sunflower seeds, and chia seeds.
In 1921, Rollin Turner Woodyatt reviewed the research on diet and diabetes. He reported that three water-soluble compounds, β-hydroxybutyrate, acetoacetate and acetone (known collectively as ketone bodies), were produced by the liver in otherwise healthy people when they were starved or if they consumed a very low-carbohydrate, high-fat diet.[10] Dr. Russell Morse Wilder, at the Mayo Clinic, built on this research and coined the term ketogenic diet to describe a diet that produced a high level of ketone bodies in the blood (ketonemia) through an excess of fat and lack of carbohydrate. Wilder hoped to obtain the benefits of fasting in a dietary therapy that could be maintained indefinitely. His trial on a few epilepsy patients in 1921 was the first use of the ketogenic diet as a treatment for epilepsy.[10]
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]
Hi Kelly, All packaged foods will have a nutrition label that list the macros per serving, including fat, protein and cabrohydrates. Net carbs, which is what most people look at for low carb and keto, are total carbs (the amount on the label) minus fiber and sugar alcohols, as explained in the article above. I have a low carb food list here that gives you a full list of all the foods you can eat, and the net carbs in each. You can also sign up above to be notified about the meal plans, which are a great way to get started.

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’d like to add to your last point because my uterus hated me for a week! I have the IUD (Mirena) and I honestly don’t remember when my last period was, guesstimating I’d say 8 months ago. Since having the IUD I only spot and rarely have a period (I’ve had it since 2014), but OMG my hormones must’ve been all over the place because I not only got a heavy period but I had it for 9 days straight!
I have one more question. You stress salt in this diet but I was wondering why you don’t recommend salted nuts. Is there a reason? I will just replace the almonds with string cheese if that is the case but I just can’t handle raw unsalted nuts. To me they taste like dirt! But I love salted ones so I was curious if we need the salt can I eat my salted almonds or pistachios? Just trying to figure out where the salt can be utilized. Thanks for all you help! Day 3 and going strong!
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:

On the ketogenic diet, carbohydrates are restricted and so cannot provide for all the metabolic needs of the body. Instead, fatty acids are used as the major source of fuel. These are used through fatty-acid oxidation in the cell's mitochondria (the energy-producing parts of the cell). Humans can convert some amino acids into glucose by a process called gluconeogenesis, but cannot do this by using fatty acids.[56] Since amino acids are needed to make proteins, which are essential for growth and repair of body tissues, these cannot be used only to produce glucose. This could pose a problem for the brain, since it is normally fuelled solely by glucose, and most fatty acids do not cross the blood–brain barrier. However, the liver can use long-chain fatty acids to synthesise the three ketone bodies β-hydroxybutyrate, acetoacetate and acetone. These ketone bodies enter the brain and partially substitute for blood glucose as a source of energy.[55]


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.)
Hi Mellissa. I am starting your 3 day kick start menu today (again) and was wondering, how do you calculate the carbs in sugar free syrup (with the LC pancakes)? Do you subtract the sugar alcohols the same as you do fiber? I’ve added about 1 Tbsp. to the pancakes but if I don’t subtract the sugar alcohols, it would be around 14 carbs! Help? Thank you!
Just found this (link from All Day I Dream About Food on FB), but I’m on it! Starting 3-day kickstart today, then wil jump into week 1 and 2 meal plans. I just want to thank you for putting together something I can realistically follow, not confusing, and has everything I need to know all in one place! I have had a very similar low-carb gluten-free journey to what you describe, and knew that keto was going to be the solution. I had lots of info sources, but even more questions – and you answered them! Thank you, thank you – you ROCK!

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?


The Johns Hopkins Hospital protocol for initiating the ketogenic diet has been widely adopted.[42] It involves a consultation with the patient and their caregivers and, later, a short hospital admission.[18] Because of the risk of complications during ketogenic diet initiation, most centres begin the diet under close medical supervision in the hospital.[9]

Having tempting, unhealthy foods in your home is one of the biggest reasons for failure when starting any diet. To maximize your chances of success with the keto diet, you need to remove as many triggers as you can. This crucial step will help prevent moments of weakness from ruining all your hard work.If you aren’t living alone, make sure to discuss with your family or housemates before throwing anything out. If some items are simply not yours to throw out, try to compromise and agree on a special location so you can keep them out of sight.
Hi! I’m contemplating taking on the Keto lifestyle change, but am concerned that preparing 1 meal for me and then a different meal for my DH and finicky 13yo DD will be an anchor around my neck. I already dislike cooking and my crew is not going to cooperate and join me in this journey. Any words of wisdom or is this going to be one of those “put on your big girl panties, Shawn, and deal with it” kind of situations. I just see myself being sabotaged from day one. Anyone else in a similar situation? How did you go about it?
We’re going full on fats with breakfast, just like we did last week. This time we’ll double the amount of ketoproof coffee (or tea) we drink, meaning we double the amount of coconut oil, butter, and heavy cream. It should come to quite a lot of calories, and should definitely keep us full all the way to dinner. Remember to continue drinking water like a fiend to make sure you’re staying hydrated.

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.


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]

Selecting the right food will be easier as you become accustomed to the Keto approach. Instead of lean meats, you’ll focus on skin-on poultry, fattier parts like chicken thighs, rib-eye steaks, grass-fed ground beef, fattier fish like salmon, beef brisket or pork shoulder, and bacon. Leafy greens such as spinach, kale and lettuce, along with broccoli, cauliflower and cucumbers, make healthy vegetable choices (but you’ll avoid starchy root foods like carrots, potatoes, turnips and parsnips). You can work in less-familiar veggies such as kohlrabi or daikon.
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?…

Hello! I recently lost 125 lbs following a keto diet. It’s starting to creep back on. My question is, have you tried a product like Keto OS? I want to eat Keto strictly, minus one meal a week. I feel that I will maintain better this way. I don’t want to knock myself out of ketosis and take days to get back in, though. My hope was that I can go full Keto, have one meal “off” a week and follow up with Keto OS to put me right back in and stay in for another week. Thoughts? Will this work? Thank you!
So have tried Aitken’s diet (not very seriously) before but never looked into how it actually works and the processes your body goes through with food you eat and energy you use. find Keto fascinating and learning alot…on day 4, ketostix showed ‘traces’ last night. One question, i’m finding it really hard to up the fat content of my food. I like ‘clean’ foods without too many sauces, additives etc, Any tips for keeping protein low but still eating well? Carb cut to sub 10g per day and aiming to keep it at that for first fortnight.

Looking for a bit of guidance / inspiration here!! I have been eating in a low carb manner for many years and due to increased blood sugar decided to try a Keto diet. I’ve been living on meat, eggs & cheese for the past 6 weeks or so & have never gotten into ketosis. I check the ketones with a blood monitor and never get higher than 0.3, not a high enough level to be in ketosis. All fruit and most veggies raise my BG so they have been eliminated from my diet. To complicate things I have had many surgeries & injuries that don’t allow me to get any exercise. Any suggestions?
A modified version of the ketogenic diet, which allows you to eat protein more liberally — at 20 to 30 percent of your total calories — with the same carbohydrate restriction, is the more commonly used version of the diet today. Some of the aims of the latest version of the ketogenic diet are weight loss, weight management, and improved athletic performance.
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.
Carolyn over at All Day I Dream About Food is a diabetic who eats low carb and blogs low carb recipes. She would know a lot more about that then I would since I don’t have personal experience with it! She may even have some articles on her site – you should check it out! If you are monitoring your own blood sugar you could try this and see how you feel – just be super careful! Also, on the r/keto site there are some threads about diabetics who have gotten off their meds by going keto – which would indicate that it’s possible. If you head over just search diabetics and you should be able to get more information. Hope that helps!!!
What's more, it's especially important to make sure your diet is well-planned when you're eating keto-style, because the foods you can choose from are limited. In addition to checking in with a dietitian if you're able, Stefanski recommends that you "talk to your doctor and make sure she or he is aware that you'll be starting a diet that completely changes how your body metabolizes energy." You might also want to check your most recent bloodwork levels for things such as cholesterol, vitamin D, and other indicators of health because these can change while on keto. That's because for some people, a prolonged keto diet can result in certain nutritional deficiencies or even high cholesterol. But most experts will tell you that the ketogenic diet is not a permanent lifestyle change (as could be the case for something like the 80/20 approach to eating or a Mediterranean eating style).
There are so many tricks, shortcuts, and gimmicks out there on achieving optimal ketosis – I’d suggest you don’t bother with any of that. Optimal ketosis can be accomplished through dietary nutrition alone (aka just eating food). You shouldn’t need a magic pill to do it. Just stay strict, remain vigilant, and be focused on recording what you eat (to make sure your carb and protein intake are correct).
There are theoretically no restrictions on where the ketogenic diet might be used, and it can cost less than modern anticonvulsants. However, fasting and dietary changes are affected by religious and cultural issues. A culture where food is often prepared by grandparents or hired help means more people must be educated about the diet. When families dine together, sharing the same meal, it can be difficult to separate the child's meal. In many countries, food labelling is not mandatory so calculating the proportions of fat, protein and carbohydrate is difficult. In some countries, it may be hard to find sugar-free forms of medicines and supplements, to purchase an accurate electronic scale, or to afford MCT oils.[53]

Hi Melissa! Thanks for this an awesome resource, thank you so much! A quick question – do you have any suggestions for doing keto with a milk allergy? I’m gluten and dairy free due to food sensitivities, but I’d love to try keto – the only problem is that 99% of the keto recipes/guides/meal plans that I’ve found a full of DELICIOUS but evil cheese! Thanks for your help :)

Because the ketogenic diet alters the body's metabolism, it is a first-line therapy in children with certain congenital metabolic diseases such as pyruvate dehydrogenase (E1) deficiency and glucose transporter 1 deficiency syndrome,[34] which prevent the body from using carbohydrates as fuel, leading to a dependency on ketone bodies. The ketogenic diet is beneficial in treating the seizures and some other symptoms in these diseases and is an absolute indication.[35] On the other hand, it is absolutely contraindicated in the treatment of other diseases such as pyruvate carboxylase deficiency, porphyria and other rare genetic disorders of fat metabolism.[9] A person with a disorder of fatty acid oxidation is unable to metabolise fatty acids, which replace carbohydrates as the major energy source on the diet. On the ketogenic diet, their body would consume its own protein stores for fuel, leading to ketoacidosis, and eventually coma and death.[36]

Could you please email me, I’m starting this diet for 2 reasons. 1 is to drop weight fast for a beach trip at the end of June, and also I want to change my lifestyle to keep the weight off and be more healthy, so it’s not going to be just a quick fix until June, then go back to the way I ate before. I know how to count the carbs, subtracting the fiber. But I am stuck on how do I know how much protein to eat, and what kind is best. I would really appreciate your help. My email is Karenwsc43@aol.com, I’m afraid I won’t be able to find this site again if you answer me here. I would really appreciate it! Thanks.
What about fruits and vegetables? All fruits are rich in carbs, but you can have certain fruits (usually berries) in small portions. Vegetables (also rich in carbs) are restricted to leafy greens (such as kale, Swiss chard, spinach), cauliflower, broccoli, Brussels sprouts, asparagus, bell peppers, onions, garlic, mushrooms, cucumber, celery, and summer squashes. A cup of chopped broccoli has about six carbs.
