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.
Although the exact role of the ketogenic diet in mental and brain disorders is unclear, there has been proof of its efficacy in patients with schizophrenia. And, to boot, the ketogenic diet works to reverse many conditions that develop as a side effect of conventional medications for brain disorders, like weight gain, type 2 diabetes and cardiovascular risks. More research is needed to understand the role of the ketogenic diet in treating or improving schizophrenia, as the current available studies are either animal studies or case studies, but the benefits of a high fat, low carbohydrate diet in neurology is promising.

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.
In another study that involved mice with brain tumors, administration of 65 to 75 percent of the recommended daily calories helped reduce tumor growth by 35 and 65 percent among two different test groups. Total carb consumption was restricted to 30 grams only.14 A different mice study strictly limited carb consumption to 0.2 percent only, which helped reduce the growth of glucose-fermenting tumors.15
Aside from carb flu, be warned that staying in long-term, continuous ketosis may have drawbacks that may actually undermine your health and longevity. To stay on the safe side, I recommend undergoing a cyclic ketogenic diet. The "metabolic magic" that ketosis brings to the mitochondria actually occurs during the refeeding phase, not during the starvation phase.
The keto diet (also known as ketogenic diet, low carb diet and LCHF diet) is a low carbohydrate, high fat diet. Maintaining this diet is a great tool for weight loss. More importantly though, according to an increasing number of studies, it helps reduce risk factors for diabetes, heart diseases, stroke, Alzheimer's, epilepsy, and more1-6.On the keto diet, your body enters a metabolic state called ketosis. While in ketosis your body is using ketone bodies for energy instead of glucose. Ketone bodies are derived from fat and are a much more stable, steady source of energy than glucose, which is derived from carbohydrates.
Some dairy products can be used in moderation, such as heavy whipping cream and most cheeses. This would depend on your individual sensitivity to dairy (some people digest it better than others) and on the particular type of food. Milk contains a relatively high amount of carbs (4 to 5 g per 100 ml) and should be limited or avoided, as well as store-bought yogurt. You can, however, have unsweetened almond milk or heavy cream. Make sure to check the labels carefully when buying dairy products, as some of them contain a rather high amount of carbs. Some people also find that eliminating dairy helps them to lose weight faster, which might be something you want to consider in case you stall.

KetoVale˜s Tip: Exogenous ketones are NOT a magic pill or a carb blocker. You should be making better choices about your diet meal plan first and then ask yourself if you want to or how you can supplement afterward to help out. Remember it's a supplement and not supposed to be used as an eraser to erase eating choices (by definition, supplement is a thing added to something else in order to complete or enhance it). It's like building muscles, you can take supplements, but if you don't workout and eat right, the muscles won't show up. The supplements aren't going to lift those heavy weights for you. There's no magic bullet.
Although studies have shown that the keto diet can reduce seizures for children with epilepsy, there is no evidence indicating that keto helps with other brain disorders or improves mental cognition, according to Harvard Health Publishing. Some studies show that keto may lower blood sugar for people with type 2 diabetes, but there is not enough long-term research to determine whether it's safe and effective for diabetics.

This book is split into 3 parts: The Ketogenic Lifestyle, The 14-day Meal Plan, and the recipes. Before this book, I really didn't fully understand what a Ketogenic Diet was. Chapter 1 defines it for me in 4 words, Low-Carb, High-Fat. This diet promotes fresh whole foods and healthy fats & oils, and cuts out processed, chemically treated foods. It also tells you that when you start a Keto Diet, you'll most likely experience the Keto-Flu!
Before we discuss how to measure ketone levels, let's set some guidelines for optimal ketone levels. Nutritional ketosis is detected when levels begin to read at 0.5 mmol/L of ketones in the blood, but your optimal ketone level will depend on your personal goals. For instance, if your goal is to lose weight, your target ketone level will be lower than someone who wants to improve mental performance. The following table provides some general guidelines based on your goal.
When you're first getting started, it can be helpful to use a blood or breath ketone meter. What these meters do is measure the amount of ketones (the energy source your body is switching to) in your blood or your breath. Knowing those amounts and seeing how they increase or decrease depending on what you're eating daily can often be a motivating and helpful indicator of the transition occurring in your body.
If you start at 20g of carbohydrates a day, you should slowly move to 50 as you reach your goal. Once you reach your goal, you can up your carbs as you see how they effect your weight. If you eat fruit for a week and gain weight, cut back. You have to figure out what works best for you. Ketosis is usually reached by only consuming 50g of carbs or less each day so that should be your starting range. I would not move past this until you have reached your goal weight and started to exercise daily (more about exercise is at the bottom of this post).
Some dairy products can be used in moderation, such as heavy whipping cream and most cheeses. This would depend on your individual sensitivity to dairy (some people digest it better than others) and on the particular type of food. Milk contains a relatively high amount of carbs (4 to 5 g per 100 ml) and should be limited or avoided, as well as store-bought yogurt. You can, however, have unsweetened almond milk or heavy cream. Make sure to check the labels carefully when buying dairy products, as some of them contain a rather high amount of carbs. Some people also find that eliminating dairy helps them to lose weight faster, which might be something you want to consider in case you stall.

A related clinical diet for drug-resistant epilepsy is called the medium-chain triglyceride ketogenic diet, in which MCT oil is extensively used because it's more ketogenic than long-chain triglycerides. (13a) Another dietary therapy for epilepsy called Low Glycemic Index Treatment (LGIT) was developed in 2002 as an alternative to the ketogenic diet. LGIT monitors the total amount of carbohydrates consumed daily, and focuses on carbohydrates that have a low glycemic index.) (13b)
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.
This is an adaptation period, where we're essentially re-training our muscles and our brain to use fat as the primary fuel source instead of glucose. This adaptation can take a couple of weeks to a couple of months. As a hallmark of being keto-adapted and not just in ketosis, the skeletal muscles are able to burn fat directly for fuel, and the brain relies on the higher volume of ketones in the blood as its main source of energy.
¢ Constipation: No one likes to feel backed up, and sadly if you're not careful about your diet choices when going keto, it could become a regular concern. One 10-year (albeit small) study looking at the effects of a keto diet on young children found that 65 percent experienced digestive woes. Thankfully, going keto is not a life sentence for problem bowels. Since you're cutting out whole grains and fruit (two of the most common sources of fiber), aim to up your fiber-rich veggies, and consider a supplement.

The biggest challenge with vegan and vegetarian diets is getting enough protein. These diets are traditionally lower in protein anyway, since they exclude the concentrated proteins in animal flesh. These individuals may want to include plant-based protein powders and shakes. Be wary of the ingredients, since these powders may contain various sugars that aren't compatible with a ketogenic diet.


¢ Potassium: With the approved list of foods being so brief, you might not be getting in enough fruits and veggies on keto. One of the biggest impacts? A potassium deficiency”and all of the lovely constipation and muscle cramps that accompanies it. Aim to up your intake of foods like spinach, avocado, tomatoes, kale and mushrooms to get your potassium fix.
¢ Fighting inflammation ” The human body can use both sugar and fat as fuel sources. However, the latter is preferred because it is a cleaner, healthier fuel that releases far fewer reactive oxygen species (ROS) and secondary free radicals. By eliminating sugar from your daily food consumption, you're decreasing your risk of developing chronic inflammation throughout your body.
¢ Standard ketogenic diet (SKD) ” SKD is the type I typically recommend for most people, because it is very effective. It focuses on high consumption of healthy fats: As I explain in my book, "Fat for Fuel," you should aim for having 70 to 85 percent of your total daily calories to come from healthy fats. For your protein intake, the general rule of thumb is to follow the formula of 1 gram of protein for every kilogram of your lean body mass.

Bulk buy and cook. If you're someone who doesn't like to spend a lot of time in the kitchen, this is the best of both worlds. Buying your food at bulk (specifically from wholesalers) can reduce the cost per pound tremendously. Plus, you can make ahead food (bulk cook chicken thighs for pre-made meat, or cook entire meals) that are used as leftovers, so you spend less time cooking.
¢ Weight loss ” If you're trying to lose weight, then a ketogenic diet is one of the best ways to do it, because it helps access your body fat so that it can be shed. Obese people in particular can benefit from this method. In one study, obese test subjects were given a low-carb ketogenic diet and a low-fat diet. After 24 weeks, researchers noted that the low-carb group lost more weight (9.4 kilograms or 20.7 pounds) compared to the low-fat group (4.8 kilograms or 10.5 pounds).1
Instead of thinking about the total carbs you're eating, assess what those carbs provide to you. Do the majority of your carbs come from fruit and vegetables, with a payload of fiber and disease-fighting antioxidants? Fantastic. Or are you consuming them in the form of added sugars (cookies, candy, soda) or refined flour? If you are, you know what to do.
A lot of changes are happening in your body and you're going to feel it! The first five to seven days can be pretty rough, but your body is getting over its dependency on sugar. During this time of transition it is essential that you supplement electrolytes. Your body is flushing out lots of water, and with that goes electrolytes. The Keto Flu can be greatly reduced if you add sodium, potassium and magnesium to your diet. Check out our supplements page for a list of electrolyte supplements we recommend. Stay on course and you'll start feeling better in no time!

Add bone broth to your diet, which can help restore electrolytes that are lost during ketosis. When you follow a keto diet, even if you're drinking a lot of water, you will lose a lot of water weight and also flush essential electrolytes out of our system, including magnesium, potassium or sodium. Adding bone broth is a great way to replenish these naturally, in addition to getting other nutrients and amino acids.

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:
Our bodies are incredibly adaptive to what you put into it “ when you overload it with fats and take away carbohydrates, it will begin to burn ketones as the primary energy source. Optimal ketone levels offer many health, weight loss, physical and mental performance benefits.1There are scientifically-backed studies that show the advantage of a low-carb, ketogenic diet over a low-fat diet. One meta-analysis of low-carbohydrate diets showed a large advantage in weight loss. The New England Journal of Medicine study resulted in almost double the weight loss in a long-term study on ketone inducing diets.

On this hack, participants are encouraged to eat eggs “ and a lot of them. The theme with these hacks and other short term solutions is limiting calories to 1000 or less, and this is no exception. While fried, scrambled, and poached are perfect options for this hack, there are many creative recipes where people have created desserts, beverages, and bread substitutes with eggs. This hack is also known as a stall breaker, so if you're stuck at a certain weight for three weeks or more, give the egg fast a try for a few days.
5) By now you should know both where you are and where you want to be. Those are the first steps. Now it's time to start planning your meals. You can use these food lists to help you figure out what kinds of foods you should be eating. Remember this is not a diet plan that has an end date. This is a lifestyle change that you will pass on to your children.
Other experts say the long-term accumulation of ketones could be harmful. œThose ketones are emergency fuel sources, and we're not meant to run on them long-term, says Kristen Kizer, a registered dietitian at Houston Methodist Hospital. œKetones are negatively-charged molecules, which means they're acidic. When you build up ketone bodies in your system, you're building up acid. One of the ways your body buffers acid is by pulling calcium from your bones. Kizer also notes that the diet isn't very balanced and involves a very high intake of animal products, which generally do not protect against cancer, diabetes, or other diseases.

¢ Multiple Sclerosis: In a small 2016 study, patients with multiple sclerosis (MS) were put on a ketogenic diet. After six months, they reported improved quality of life, as well as physical and mental health improvements. Before doctors or researchers can make a connection between keto and MS, they need bigger sample sizes and more thorough research. Still, the preliminary findings are exciting.
On a keto diet, weight loss can often be substantial and happen quickly (especially for those who start the diet very overweight or obese). The 2013 study published in the British Journal of Nutrition found that those following a keto diet œachieved better long-term body weight and cardiovascular risk factor management when compared with individuals assigned to a conventional low-fat diet (i.e. a restricted-energy diet with less than 30 percent of energy from fat). (4)
Taking your first step into the ketogenic diet is an exciting phase for your health. But before coming up with an actual ketogenic diet food list, it's important to first take a look at what you're eating now and take out anything that's unhealthy. This means that you have to remove sugars, grains, starches and packaged and processed foods from your diet. Basically, anything that won't add to your new eating regimen has to go. This is what I call a "pantry sweep."

Con: Results can vary depending on how much fluid you drink. By drinking more water, you dilute the concentration of ketones in the urine and thus a lower level of ketones will be detected on the strips. The strips don't show a precise ketone level. Finally, and most importantly, as you become increasingly keto-adapted and your body reabsorbs ketones from the urine, urine strips may become unreliable, even if you're in ketosis.
