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]
because the recipes don’t mention quantities it’s hard to know how much it’s okay to eat of the carb foods. How much carbs is in those foods like kale, cauliflower, lettuce a.s.o. What about mushrooms ? Love to use them as a ‘filler’ instead of bread. Also hard to know how much is too much protein? Cheese, meat, bacon, yoghurt, tuna…. they all are full of protein.
Other kinesiologists think the keto diet could have dangerous effects on athletic performance, and it's tough to know what potential side effects a long-term high-fat diet might have for a healthy person, since we don't have any solid study results yet. Low-carb diets like keto can make it easy to neglect key nutrients like magnesium, calcium, and potassium found in fresh, high-carb foods like beans, bananas, and oats.
Hi Gigi, Low carb and keto is about the balance of macronutrients eaten (fat, protein and carbs), not specifically meat or lack thereof. Most people on keto do eat meat, though some people do vegetarian keto. Fat is actually necessary for many body processes. There is no issue for the kidneys with a high fat diet, but if you eat too much protein that isn’t great for the kidneys. It’s a common misconception that keto is high protein (it isn’t). Keto is great for diabetics as it naturally helps stabilize insulin. All of this being said, please know I’m not a doctor and you should consult your doctor on any medical questions or before starting any diet. If you have more questions that aren’t medical questions, I recommend our low carb & keto support group here.
Beverages: It’s common to become dehydrated on the keto diet. Your insulin levels drop when you restrict carbs, and low insulin makes it harder for your body to retain sodium and water.[9] Drink plenty of plain water, and sip on bone broth to replenish electrolytes, especially during the first couple of weeks when your body is adjusting to the new diet.
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?

What a great find! Over the years I have been on Atkins, FatBellyDiet, and Livin’LaVida menu (all great resources).. and a random exerciser with success. I’m a little late for my new year’s resolution, but summer is right around the corner. In motivation to jump back into what I know works so well for me, I’ve found IBIH! I put my scale away a long time ago, as it only causes me angst (I’ve always been high in the BMI scale, even at my lowest weight, highest fitness level). So, I use a tape measure, love to see the inches melt off in two weeks. Which in itself, motivates me back into fitness activities.
In many developing countries, the ketogenic diet is expensive because dairy fats and meat are more expensive than grain, fruit and vegetables. The modified Atkins diet has been proposed as a lower-cost alternative for those countries; the slightly more expensive food bill can be offset by a reduction in pharmaceutical costs if the diet is successful. The modified Atkins diet is less complex to explain and prepare and requires less support from a dietitian.[54]
Many ketogenic dieters also swear by MCT oil. (MCT simply stands for medium chain triglycerides.) MCT's energy-sustaining powers can be explained as follows: When MCT oil is metabolized in the body, it behaves more like a carbohydrate than a fat. Unlike other fats, MCT oil does not go through the lymphatic system. Instead, it is transported directly to the liver where it is metabolized so it releases energy like a carbohydrate and creates lots of ketones (which can be used for fuel) in the process.
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]
I just want to say THANK YOU for putting together such an informative, encouraging, and realistic introduction to what it means to follow a Keto plan. I have finally decided that I can no longer put off giving myself a food makeover. Started following the Keto guidelines today, and I’m determined to stick with it. Your site gives me the confidence to be able to do it. Thank you!
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?!?!
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!
As always, I’m late to the party. Thank you so much for this fantastic resource! I did this 6 years ago, lost 60 lbs. and maintained it for five years. But over the past year or so, my weight has gone up and down the same 18 lbs. To add insult to injury, I’m now borderline pre-diabetic (higher A1C than is healthy), my anxiety attacks have returned and so I’m on medication for that. It’s time to go back to what I know makes me feel better and get off the sugar and garbage once and for all.

A: The most common ways to track your carbs is through MyFitnessPal and their mobile app. You cannot track net carbs on the app, although you can track your total carb intake and your total fiber intake. To get your net carbs, just subtract your total fiber intake from your total carb intake. I have written an article on How to Track Carbs on MyFitnessPal.

Physicians of ancient Greece treated diseases, including epilepsy, by altering their patients' diet. An early treatise in the Hippocratic Corpus, On the Sacred Disease, covers the disease; it dates from c. 400 BC. Its author argued against the prevailing view that epilepsy was supernatural in origin and cure, and proposed that dietary therapy had a rational and physical basis.[Note 3] In the same collection, the author of Epidemics describes the case of a man whose epilepsy is cured as quickly as it had appeared, through complete abstinence of food and drink.[Note 4] The royal physician Erasistratus declared, "One inclining to epilepsy should be made to fast without mercy and be put on short rations."[Note 5] Galen believed an "attenuating diet"[Note 6] might afford a cure in mild cases and be helpful in others.[11]

There are several types of the keto diet, but essentially, to achieve a state of ketosis, you have to severely reduce the amount of carbs you eat. (You can use this ketogenic calculator to create a custom food plan.) Data suggest the average American man over age 20 consumes 47.4 percent of his daily calories from carbs, and the average American woman over age 20 consumes 49.6 percent of her daily calories from carbs. (3) But in the classic ketogenic diet, which was originally used for the management of seizure disorders, 80 to 90 percent of calories come from fat, 5 to 15 percent come from protein, and 5 to 10 percent come from carbohydrates.
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).
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.
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 off I just want to say thank you for the 3 day meal plan to get started. I stumbled across Keto about a week ago and I have been reading and reading and reading and then essentially got super confused and though that this was not for me! But then I came across your website and my my you break it down for people like me who are just looking for guidance to get started. I am hoping to start soon as I do go on a business trip begging of next week and I am afraid to start and then boom off the band wagon. My goal is to start next Thursday…..(fingers crossed this works) everything else has failed and dieting has been a struggle since I had a hysterectomy due to cancer. Now my weight is out of control and I am the biggest I have ever been! 251 pounds and I am 5′ 2″ and none of my clothes fit!! Makes it hard to get excited in the morning when getting ready to endure the day!

Because people with type 2 diabetes are at an increased risk for cardiovascular disease, there’s a specific concern that the saturated fat in the diet may drive up LDL, or “bad,” cholesterol levels, and further increase the odds of heart problems. If you have type 2 diabetes, talk to your doctor before attempting a ketogenic diet. They may recommend a different weight-loss diet for you, like a reduced-calorie diet, to manage diabetes. Those with epilepsy should also consult their doctor before using this as part of their treatment plan.
