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.
Blanket statement: It’s always best to check with your doctor before starting on this regimen. With that said, “the keto diet isn’t recommended for those with liver or kidney disease, or someone with a medical condition, such as a gastrointestinal issue, who can’t metabolize high amounts of dietary fat,” says Sarah Jadin, a Los-Angeles based registered dietitian and founder of Keto Consulting, LLC. If you’ve had your gallbladder removed, the keto diet may be a no-go. Women who are pregnant or breastfeeding and people with certain rare genetic disorders shouldn’t try this diet.
A typical day on a keto diet might include breakfast of fried eggs or a frittata with eggs, mushrooms, cheese and butter; lunch of chicken thighs with cabbage and olive oil; and dinner of bacon burgers with green beans and butter. The emphasis on proteins and fats also is intended to provide a feeling of fullness, which can make the eating plan easier to stick to.

No matter what your diet has been before now, keto will be a big change. If you're coming from a standard American diet (SAD), your carbs will go way down, your protein may either go up or down, and your fat will go way up. If you're coming from a bodybuilding-style diet, your fat intake will jump to alarming levels, and your protein will likely drop significantly.

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?


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.
Your glycogen stores can still be refilled while on a ketogenic diet. A keto diet is an excellent way to build muscle, but protein intake is crucial here. It’s suggested that if you are looking to gain mass, you should be taking in about 1.0 – 1.2g protein per lean pound of body mass. Putting muscle on may be slower on a ketogenic diet, but that’s because your total body fat is not increasing as much.5Note that in the beginning of a ketogenic diet, both endurance athletes and obese individuals see a physical performance for the first week of transition.

In the first week, many people report headaches, mental fogginess, dizziness, and aggravation. Most of the time, this is the result of your electrolytes being flushed out, as ketosis has a diuretic effect. Make sure you drink plenty of water and keep your sodium intake up.6One of the fathers of keto, Dr. Phinney, shows that electrolyte levels (especially sodium) can become unbalanced with low carb intake.
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.
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.
You may also be a great candidate for the Keto diet if you experience migraines, joint pain, muscle weakness or mental fatigue. In addition, "Keto diet can be beneficial for mental health conditions like depression, autism and Alzheimer's". Other than that, "you can also follow this diet plan if you're trying to get pregnant since it improves fertility", she notes.

So I’m late to the party, but I just found your blog last week. I can’t thank you enough for these simple, easy to follow recipes, meal plans, and shopping lists! They are so helpful and I appreciate the time you put into this. I did the 3 day kickstart for 5 days, mostly because I still had leftover food, and I’ve lost 5 lbs. so far! I’ve never done low carb before, and usually eat a mainly vegetarian diet, so this is very different for me, I think I purchased more meat in the past week then I have in the past year! I am strictly following the plan, but do you think after I’ve lost the weight I’ve wanted to, transitioning back to a vegetarian diet (with eggs and dairy) is possible or just a recipe for disaster?

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]
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.
I am going to give the three day plan a try and then hope to move on to Week 1 and 2. I’ve used so many of your recipes in the past and people absolutely RAVE about them. I just made your Cream Cheese Pancakes and they were really, really good! I am pretty good about eating low carb so I haven’t had anything even resembling a pancake that I didn’t feel guilty about. You are AWESOME!!! I get so tired of eggs! THANK YOU!!!!
Love the set of instructions and advice; this will be what I point people at now when they want to know how to start. I avoided most “keto flu” symptoms by getting just 30 minutes a day of gentle exercise. Somewhere deep in “The Art & Science of Low Carb Living” it explains why. The Atkins books don’t mention it because their approach is to position fitness as an entirely optional thing.

6. Don’t obsessively plan everything and overwhelm yourself so it feels harder than it has to. This may be controversial for some, but I’m here to tell you not to worry about calories, or nitrates, or Omega 3 vs Omega 6, or if the meat you’re eating skipped about on acres of lush pastureland, while being hand fed organic vegan feed by the tiny perfect hands of 1000 virgin milkmaids.

Protein: Keep in mind that keto is high-fat, and not high-protein, so you don’t need to eat very much meat. Too much protein turns into glucose in the body, making it harder to stay in ketosis. Stick to fatty cuts of grass-fed, pasture-raised, or wild meat, and wild-caught fish. Red meats, offal/organ meats, pork, eggs (preferably pastured), fish, shellfish, and whey protein concentrate.
Hey folks, I am a 55 year old guy whos used to be in good shape, so was wondering if I could use the Keto diet to lose fat and gain muscle, obviously I would have to increase caloric intake as I am weight training and performing cardio so was wondering about supplements, vits and minerals as well whey protein, as I am trying to lose body fat and build muscle I need extra calories.. plus creatine and NO pre work out and a post work supplement…

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. 
Well, apart from following this diet chat, you need to have some snacks every two hours that will help your system run properly. For the snacks, include nuts and berries, baby carrots, boiled eggs, a fruit, slices of apple fried in almond butter, beef steak made at home, any leftovers of previous night. All these will enhance the positive levels in your Ketogenic diet menu plan.
Note: Are you a vegetarian or vegan and want to go on a ketogenic diet? It’s still possible! Just keep in mind that the dietary restrictions can sometimes be a little bit intense. Make sure to plan ahead and prepare to aid your success. To help out, we’ve published articles (with 7 day meal plans included) for both the vegetarian ketogenic diet and the vegan ketogenic diet.
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]
The ketogenic diet has recently become very popular, and many food companies want to cash in by putting a “ketogenic” or “low carb” label on a new product. Be very cautious of special “keto” or “low-carb” products, such as pastas, chocolate bars, energy bars, protein powders, snack foods, cakes, cookies and other “low carb” or “ketogenic” treats. Read all labels carefully for natural low carb ingredients. The fewer ingredients the better.
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.
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.

Help me please! Ketosis is the only thing that has ever helped to alleviate my chronic migraines but it is so hard for me to stick to because all of the plans I can find ( like this 3 day one ) use dairy products to fill most of the fat content. I am deathly allergic to dairy and soy products. How do I stay keto without all of the cheese and cream?!?!
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]
Hi there. I’ve been off the low carb band wagon for TOO long now (years!) and weight has been creeping up to a disgusting level and cravings are through the roof. I’ve been trying to get back on track the last two days but accidentally had a bit of chocolate last night and too many cream cheese “clouds” from another low carb site and your truffles!. However, I’ve lost 800g so hopefully heading towards ketosis. Am going to start following your plans though as it is so great to have some structure and know what works for other people rather than re-creating the wheel and experimenting! So thank you so much for putting these plans and recipes together!
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!!!
Infants and patients fed via a gastrostomy tube can also be given a ketogenic diet. Parents make up a prescribed powdered formula, such as KetoCal, into a liquid feed.[18] Gastrostomy feeding avoids any issues with palatability, and bottle-fed infants readily accept the ketogenic formula.[30] Some studies have found this liquid feed to be more efficacious and associated with lower total cholesterol than a solid ketogenic diet.[3] KetoCal is a nutritionally complete food containing milk protein and is supplemented with amino acids, fat, carbohydrate, vitamins, minerals and trace elements. It is used to administer the 4:1 ratio classic ketogenic diet in children over one year. The formula is available in both 3:1 and 4:1 ratios, either unflavoured or in an artificially sweetened vanilla flavour and is suitable for tube or oral feeding.[50] Other formula products include KetoVolve[51] and Ketonia.[52] Alternatively, a liquid ketogenic diet may be produced by combining Ross Carbohydrate Free soy formula with Microlipid and Polycose.[52]
My daughter and I started low carb dieting/no flour,no sugar 6weeks ago. During that time I lost a total of 4 lbs. It was so frustrating because it felt like I should be losing more. So, in our search to figure out what we were doing wrong we found this site. We started with the 3 day plan!!! It has been wonderful. Every single recipe you provide has been absolutely Delicious. I have felt the most satisfied on your plan and as of day #2 I have already lost 6 lbs. 6!!! I worked 6 weeks just to lose 4!!!
A systematic review in 2018 looked at sixteen studies on the ketogenic diet in adults. It concluded that the treatment was becoming more popular for that group of patients, that the efficacy in adults was similar to children, the side effects relatively mild. However, many patients gave up with the diet, for various reasons, and the quality of evidence inferior to studies on children. Health issues include high levels of low-density lipoprotein (LDL), high total cholesterol, and weight loss.[23]
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?

Hi Melissa! So I went on ideal protein to lose weight before my daughter’s wedding. It was great! I loved the products and of course I loved losing 64 pounds. HOWEVER, after the wedding I started to enjoy drinking again. And since July 2014, I have gained 34 pounds. I have yo-yo’d with IP but after the taste of real food it is very difficult for me to stay on track. I know it works but after 3 weeks losing 9 pounds I end up eating a whole pizza! Anyway, I love all of your insight to keto. How do you think your suggestions will work if I am throwing in a IP packet for snack instead of say almonds? I just want to feel better again and not spend $100 every week on IP. Thanks for your time and commitment to helping those of us who are weak!


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."
