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]

Higher cholesterol is generally due to HDL (the good cholesterol) increasing – lowering your chance of heart disease. You may see increased triglyceride counts, but that’s very common in people losing weight. These increases will subside as weight loss normalizes.

The ketogenic diet is not a benign, holistic or natural treatment for epilepsy; as with any serious medical therapy, there may be complications.[27] These are generally less severe and less frequent than with anticonvulsant medication or surgery.[27] Common but easily treatable short-term side effects include constipation, low-grade acidosis and hypoglycaemia if there is an initial fast. Raised levels of lipids in the blood affect up to 60% of children[37] and cholesterol levels may increase by around 30%.[27] This can be treated by changes to the fat content of the diet, such as from saturated fats towards polyunsaturated fats, and, if persistent, by lowering the ketogenic ratio.[37] Supplements are necessary to counter the dietary deficiency of many micronutrients.[3]
By 2007, the ketogenic diet was available from around 75 centres in 45 countries, and less restrictive variants, such as the modified Atkins diet, were in use, particularly among older children and adults. The ketogenic diet was also under investigation for the treatment of a wide variety of disorders other than epilepsy.[1]
Last, but certainly not least, is sticking to the diet! Ketosis is a process that happens in your body. You can’t just have “that one” cheat meal. If you do, it can hamper progress for up to a week before your body is back in ketosis and normally functioning again.
If you need to, drink water with a sprinkling of salt in it. Just keep drinking water (I recommend 4 liters a day), and keep eating salt. It will help, trust me. If you’re worried about high blood pressure and salt, don’t be! Recent studies show that the sodium intake and blood pressure are not as correlated as we so once believed.
Once you figure out your macros, it’s all about finding low carb foods you like to meet your goals. Use our 7-day Keto Diet Meal Plan to start and then use our list of approved keto foods to create your own winning meal plan.
This is highly unlikely to occur in normal circumstances because for most people it’s a challenge to get into optimal ranges for ketosis so getting into the range where you need medical intervention isn’t likely.

In contrast, multivitamins aren’t a good solution as they are synthetic and lack a lot of nutrients like polyphenols, antioxidants and fiber that green powders and whole food sources provide. And the lack of fats and enzymes make the nutrients they do contain very difficult to process properly. Just because you’re putting something in your body doesn’t mean your body can use it.
After increasing water intake and replacing electrolytes, it should relieve most all symptoms of Keto Flu. For an average person that is starting a ketogenic diet, eating 20-30g of net carbs a day, the entire adaptation process will take about 4-5 days. My advice is to cut your carbs to fewer than 15g to ensure that you are well on your way into ketosis within one week. If you are experiencing any more keto flu symptoms, double check your electrolyte intake and adjust.
Glucose will always be your body’s preferred energy source. When glucose is present, your body will resist burning fat. By removing carbohydrates and replacing them with fat, you are forcing your body to burn that fat for fuel.
It is possible to consume too much protein on the ketogenic diet. While low carb diets call for a higher protein intake, those on the standard ketogenic diet eat only a moderate amount of protein. Why? Because your body can actually break down protein for glucose (known as gluconeogenesis), thus preventing the body from reaching full ketosis.
Usually the star of unique dishes, cauliflower can be used for a variety of things. You can use cauliflower for wraps, pizza, casseroles, or even mashed “potatoes.” It’s no surprise that it’s one of the most used and most versatile ingredients in most low-carb kitchen pantries.
Option 1: BLT roll-ups with turkey and avocado. “Create a roll using bacon, lettuce, tomato, turkey, and avocado for the perfect mix of fat and protein,” says Dr. Axe. (You Could Also Try This Kale Avocado BLT Salad.)
Also Consider: For some individuals, diarrhea may be brought on by low stomach acid and/or a sluggish gallbladder. Another possibility is that you have a low-grade food sensitivity to something you are eating such as eggs, nuts, and cheese.
The ketogenic diet essentially uses your body fat as an energy source – so there are obvious weight loss benefits. On keto, your insulin (the fat storing hormone) levels drop greatly which turns your body into a fat burning machine.
This week we’re going to be keeping it simple for breakfast again. We’re going to introduce ketoproof coffee. It’s a mixture of coconut oil, butter, and heavy cream in your coffee. If this repulses you – and I know some of you are saying “WHAT?” – just put some trust in me!
Your body is used to the simple routine of breaking down carbohydrates and using them as energy. Over time the body has built up an arsenal of enzymes ready for this process and only has a few enzymes for dealing with fats – mostly to store them.

The common keto side effects that people experience come down to three primary culprits: Hypoglycemia, HPA axis dysfunction, and poor hydration/mineral balance. The following strategies will help prevent these underlying issues and their respective side effects:
Here’s a short list of foods that are keto-friendly: Avocados, animal fats, oils, animal protein (including seafood), mayonnaise, plant-based oils, leafy greens, cheese, full-fat dairy, butter and eggs.
Pretty much all of the side effects you’ll hear about happen in those first four weeks—or even in the first 4-5 days—and experienced ketogenic dieters like Wittrock swear that most of them can be chalked up to a single cause: lack of electrolytes.
All meat and seafood are included on the keto diet, as long as it’s not breaded or fried. Enjoy beef, chicken, pork, lamb, goat, turkey and veal. You can also enjoy fatty fish like salmon, tuna, trout and sardines. Always choose the highest quality meat you can afford, whether that means grass-fed or organic. Eggs are always a great choice, preferably free-range. Nuts and seeds are also fine, including almonds, pecans, chia seeds and flax seeds.
The keto diet is often grouped with other high-fat, low-carb diets such as the paleo or Atkins diets. But the reason these diets boast fat-burning benefits in the first place is because they promote ketosis. Therefore, the ketogenic diet isn’t so much a diet, but more so the basis of these diets, and the biochemical reaction that occurs when you train your body to burn fat for fuel instead of carbs.
One thing many people love about keto diet meal plans is that tracking your food is optional. “One of the biggest benefits of the ketogenic diet is that there’s no need to meticulously track your calories like you may in other diets,” notes Dr. Josh Axe, D.N.M., C.N.S., D.C., founder of DrAxe.com, best-selling author of Eat Dirt, and cofounder of Ancient Nutrition. “Because you’re filling up on fat and protein, you’re more likely to feel satisfied and energized all day long, which causes you to naturally eat less.” This isn’t to say that food tracking on keto is discouraged. “Some people may find calorie counting a useful tool to be more mindful and aware of what they’re eating, but it’s not necessary on the ketogenic diet,” says Dr. Axe, but there’s no need to get too stressed about hitting a certain caloric goal, especially if you’re not trying to lose weight.

Epilepsy is one of the most common neurological disorders after stroke,[7] and affects at least 50 million people worldwide.[8] It is diagnosed in a person having recurrent unprovoked seizures. These occur when cortical neurons fire excessively, hypersynchronously, or both, leading to temporary disruption of normal brain function. This might affect, for example, the muscles, the senses, consciousness, or a combination. A seizure can be focal (confined to one part of the brain) or generalised (spread widely throughout the brain and leading to a loss of consciousness). Epilepsy may occur for a variety of reasons; some forms have been classified into epileptic syndromes, most of which begin in childhood. Epilepsy is considered refractory (not yielding to treatment) when two or three anticonvulsant drugs have failed to control it. About 60% of patients will achieve control of their epilepsy with the first drug they use, whereas about 30% do not achieve control with drugs. When drugs fail, other options include epilepsy surgery, vagus nerve stimulation and the ketogenic diet.[7]
A business that doesn’t take a regular inventory usually goes broke – and it’s no different with us and the way we eat. Starting up on the ketogenic diet basically means we have to check in on what we need to start, what we need to stop and what we need to continue to make progress! It may be in the,
Can ketone production in the body get too high? Yes, it’s called ketoacidosis. Is it likely under normal circumstances? Not at all. For most people, it’s a challenge just to get into optimal ranges for ketosis. Getting into territory where you need medical intervention is just not likely.
Because consuming even up to 30–50 grams of net carbs daily is still dramatically less than what most people eating a “standard Western diet” are used to, many will still experience weight loss eating slightly more carbs.
People also see good weight loss results on the keto diet because eating a low carb, high fat diet can help you feel less hungry and not have to count calories or portion sizes to lose weight. Plus, cutting out the refined carbs and sugars normally present in a traditional Western diet helps avoid crazy spikes in blood sugar that can lead to the feeling of being hungry again soon after eating.
Although a standard ketogenic diet is even more restrictive in terms of carb intake, a “moderate keto diet” is another option that will very likely still be able to provide substantial weight loss results and other improvements in symptoms. Including slightly more carbs can be very useful for maintenance, allow for more flexibility, provide a higher fiber intake, and overall may feel more sustainable long term socially and psychologically.
“Once your body enters ketosis, you also begin to lose muscle, become extremely fatigued, and eventually enter starvation mode. Then it actually becomes even harder to lose weight,” Cimperman told Healthline.
“If you’re using the keto diet for medical nutrition therapy, you definitely need medical oversight to be successful,” says Jadin. “Though anyone considering the keto diet would benefit from partnering with a medical professional, such as a dietitian, who is well-versed in this diet.”
