As far as fruits are concerned, most berries are low in carbs and can be consumed from time to time, and in limited amounts. These include raspberries, strawberries, and blackberries. Blueberries are a bit higher in carbs and should be eaten sparingly. Most other fruits, however, have too many carbs in just one serving, so it is best to avoid them.
Eggs and dairy. If you think there's nothing better than butter and cheese, you're in luck! Eggs, butter and cheese are all a big part of eating Keto. You'll want to make sure your items are as unprocessed as possible, so stick to cheeses like cheddar, mozzarella and blue, and look for butter and egg products that are organic or come from free-range animals.
For a period of 3-4 days up to 2 weeks, you will be eating the minimal amount of carbohydrates and sugar (20 grams net carbs maximum per day). After this you may be able to add in small amounts of net carbs if your body can handle it, but probably not more than 50 net carbs total per day. This is tricky, because some people can't handle more than the 20 net carbs even after they have adjusted to ketosis. Others can handle 50 net carbs and easily stay in ketosis. If you feel fine at 20 net carbs and it doesn't bother you, than there's no reason to make any changes. You can test your ketosis by how you feel, or by actually testing - which is discussed in section 3.
Ketogenesis has existed as long as humans have. If you eat a very low amount of carbohydrates, you starve your brain of glucose, its main fuel source. Your body still needs fuel to function, so it taps into your reserve of ketones, which are compounds the liver creates from fat when blood insulin is low. This process is known as ketosis: It's like when a hybrid car runs out of gas and reverts to pure electricity.
There are numerous benefits that come with being on keto: from weight loss and increased energy levels to therapeutic medical applications. Most anyone can safely benefit from eating a low-carb, high-fat diet. Below, you'll find a short list of the benefits you can receive from a ketogenic diet. For a more comprehensive list, you can also read our in-depth article here >
Bonnie J. Brehm, Randy J. Seeley, Stephen R. Daniels, and David A. D'Alessio, œA Randomized Trial Comparing a Very Low Carbohydrate Diet and a Calorie-Restricted Low Fat Diet on Body Weight and Cardiovascular Risk Factors in Healthy Women, The Journal of Clinical Endocrinology & Metabolism: Vol 88, No 4; January 14, 2009. http://press.endocrine.org/doi/full/10.1210/jc.2002-021480.
The removal of many grains and fruits with such a large emphasis on fats can bring about its own set of side effects. œIf not done properly ” with most of your carbohydrates coming from fiber-rich vegetables ” you may not be getting enough fiber, which can lead to constipation, says Chris Mohr, PhD, RD, a sports dietitian based in Louisville, Kentucky, and co-owner of MohrResults.com.

But what does the science say? Results are mixed. In one Spanish study of 20 obese adults, participants were put on a low-calorie keto diet and lost an average of 40 pounds over four months. Another small experiment had a similar outcome. In a six-month Experimental & Clinical Cardiology study of 83 obese adults, those on the keto diet lost an average of 33 pounds, while lowering their bad (LDL) cholesterol levels and increasing their good (HDL) cholesterol.
¢ 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.
The book contains a two week menu for beginners. (Face it, there's a 90% chance you won't follow it to the letter, but it does help set your thinking in the right direction.) For each individual week there's a shopping list which, by itself, will help you adjust your kitchen quite a bit. There are tips on the best sweeteners (Swerve over Splenda), the oils you'll need, produce, canned and bottled items, pantry items, and meats. Something to consider as you go along is that some items, like almond and coconut flour are expensive items to stock up on, but you'll use considerably less than non-keto recipes will use for regular flour. Do what you can afford. Just know that there are some must-have staples like coconut oil and olive oil.
¢ 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.
Hi Lauren, I just started this diet. Any tips for beginning? I am not sure I am taking in enough throughout the day. I snack on cheese and red grapes, raspberries throughout the day. I have a protein shake for breakfast and lunch. and then this evening I am having a chicken salad with avocado and romaine. Like I said I don't think I am taking in enough throughout the day.
Ideally, your keto carb limit should be kept to under 50 grams a day, or 4 to 10 percent of your daily calories. This will help you transition to burning fat for fuel. However, this number may change depending on various factors. For example, if you have Type 2 diabetes, you will have to restrict your carb intake to as little as 20 grams per day. All in all, you will have to rely on your body's feedback to help you identify the ceiling amount for your carb intake.
Over the past century, ketogenic diets have also been used to treat and even help reverse neurological disorders and cognitive impairments, including epilepsy and Alzheimer's symptoms. Research shows that cutting off glucose levels with a very low-carb diet makes your body produce ketones for fuel. This change can help to reverse neurological disorders and cognitive impairment, including inducing seizure control. The brain is able to use this alternative source of energy instead of the cellular energy pathways that aren't functioning normally in patients with brain disorders.
For people with diabetes, rapidly rising ketone levels can signal a health crisis that requires immediate medical attention. When there is an absence or not enough of the hormone insulin (or the body is too resistant to insulin to allow it to drive glucose into the cells for energy), the body cannot use glucose for fuel. Insulin helps ferry glucose to our cells and muscles for energy. Instead, in this case, the body resorts to burning stored fat for energy through the process of ketosis, leading to a buildup of ketones in the body.
The keto diet works for such a high percentage of people because it targets several key, underlying causes of weight gain ” including hormonal imbalances, especially insulin resistance coupled with high blood sugar levels, and the cycle of restricting and œbinging on empty calories due to hunger that so many dieters struggle with. Yet that's not a problem with what's on the keto diet food list.
Although fat is the centerpiece of any keto diet, that doesn't mean you should be subsisting on butter-topped steaks, says Kristen Mancinelli, RD, author of The Ketogenic Diet. œA big misconception is that you should just put meat at the center of your plate and add more fat on top, she says. You also shouldn't be relying on fatty meats to hit your fat quota, she adds.
I am also working to share personal success stories on my blog. If you are planning to start this keto diet, please take before pictures, progress pictures, keep a food diary, and keep track of your weight and measurements. Then when you are ready (maybe at your halfway point, or once you reach your goal weight, you can send me your results for me to share with others).
And good news for coffee addicts: you can still have your morning cup of joe. You'll just need to adjust what you stir into it. Switch out flavored creamer for the real deal”full-fat heavy whipping cream, which has only 1 gram of carbs per tablespoon. If you want to give your java a jolt of sweet, stir in a low-carb sweetener that uses sugar alcohols. But if you can skip the sweet, even better. In time, you'll retrain your palate to not crave a sugary start to the day.
Paleo and keto can overlap, though there are some major differences in the core of each way of eating. The Paleo diet focuses on whole, natural foods that would have been available as food to our paleolithic ancestors. If it could have been hunted or foraged, then it would have been eaten. Some people on a Paleo plan also focus on what would have been growing in season, and in a certain region of the world for their genetic ancestors. Carbs are overall allowed in a Paleo plan, but they would come from whole foods like potatoes, sweet potatoes, fruits, honey, and other unprocessed sources.
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.
There are several medical studies ” such as two conducted by the Department of Radiation Oncology at the Holden Comprehensive Cancer Center for the University of Iowa, and the National Institutes of Health's National Institute of Neurological Disorders and Stroke, for example ” that show the ketogenic diet is an effective treatment for cancer and other serious health problems.

A œmoderate keto diet is an option that can still encourage substantial weight loss and other improvements in symptoms. A moderate keto diet includes more foods with carbs and, therefore, more fiber too. Carbs are usually increased to about 30“50 net grams per day, which means foods like more high-fiber veggies, some fruit or some starchy veggies can also be included.
Some people like to weigh their food when they first transition from a normal diet to a ketogenic diet, in order to have a fuller understanding of the amount of carbohydrates that they consume, although this can be used just in the beginning as a guide. But ultimately no, you do not have to weigh your food in order to be successful with a keto diet.
You are so welcome Christine! I really do believe that in order for a diet to become a lifestyle, it has to be simple otherwise people will lose interest or slip up easier. With weight loss, patience is key. Also, if you find that something is not working for you, don't be afraid to switch it up! Every body is different so what works for one, might not work for all.

I like it “ and I'm surprised I like it. I'm only down 5 lbs. after a month but I'm down 3 inches on my waist and 2 inches on my hips. I do feel better physically and I love not being hungry! I used to be that person who could eat pasta like a lumberjack “ now I often don't even finish my food. I have had a hard time sticking to 20 net carbs, I usually end up in the high 20's somewhere, but I'm in ketosis according to the testing strips. It's much harder to stick to 20 net as a vegetarian. Everything you eat has some level of carbs and they do add up. But overall, this is the only thing I've lost any weight or inches on in about 7 or 8 years. Starvation used to work until I hit 45 and then, forget it, I could eat 700 calories a day and not lose a pound. I'm so excited *something* is actually working.
I love your site but your note about Diabetic Ketoacidosis is completely wrong. DKA is not something that happens because your body produces too many ketones. It is something that happens when your body produces too many ketones, and you don't have any insulin in your system. As long as a Type 1 Diabetic takes insulin they will NOT go into DKA. Especially since DKA requires high ketones, high sugars, and low insulin.
Basically, the role of exogenous ketones is to boost the amount of ketones in your body. These products do work wonders if, after a long time on a keto diet, you don't feel energized or generally don't feel like you are at your best. Ultimately deciding to take exogenous ketones or not comes down to how you feel on your keto diet and trying to find a product with the highest possible quality.
Following a diet that drastically restricts carbohydrates requires carefully monitoring your food choices to ensure you are meeting your nutritional needs. Working together with a registered dietitian can make sure you follow this diet in a healthy manner without increasing your risk for complications or negative side effects. You can find a registered dietitian at EatRight.org.
Achieving ketosis is a pretty straightforward, but it can seem complicated and confusing with all of the information out there.4If you want to learn more about ketosis and the scientific process around it, you can visit a very in-depth discussion about on Dr. Peter Attia's website. Here's the bottom line on what you need to do, ordered in levels of importance:
For athletes, research on the keto diet highlights potential improvements in athletic performance, especially when it comes to endurance activities. An article suggests ketogenic-type diets may allow endurance athletes to rely mostly on stored fat for energy during exercise rather than having to refuel with simple carbohydrates during endurance training and competition while additionally improving recovery times. (10)
Can't you take ketone supplements? No. While it is possible to elevate ketones by taking them, œwithout the low-carb stimulus, there is no net increase in ketone production, no decrease in insulin, and no net increase in fat oxidation, says Volek. Don't trust trainers or œbody hackers who say you can induce ketosis quickly without changing your diet.
I've always heard that the brain functions well on ketones. Gluconeogenisis typically reduces ketosis, though as well? This is the first time I've heard anyone say the brain can't use anything but glucose. I know there's *preferred* sources of fuel over others, but I was also fairly certain other sources were fine.. or humans might be in a bit of trouble.
