Wondering how many carb foods you can eat and still be œin ketosis? The traditional ketogenic diet created for those with epilepsy consisted of getting about 75 percent of calories from sources of fat (such as oils or fattier cuts of meat), 5 percent from carbohydrates and 20 percent from protein. For most people a less strict ketogenic diet (what I call a œmodified keto diet) can still help promote weight loss in a safe, and often very fast, way.

On a œstrict (standard) keto diet, fats typically provides about 70 percent to 80 percent of total daily calories, protein about 15 percent to 20 percent, and carbohydrates just around 5 percent. However, a more œmoderate approach to the keto diet is also a good option for many people that can allow for an easier transition into very low-carb eating and more flexibility (more on this type of plan below).

¢ 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.

Daily, R.D., Joyce McGrory, C.R.N.P., Terrence Williams, B.S., Monica Williams, B.S., Edward J. Gracely, Ph.D., and Linda Stern, M.D., œA Low-Carbohydrate as Compared with a Low-Fat Diet in Severe Obesity, N Engl J Med 2003; 348:2074-2081. http://www.nejm.org/doi/full/10.1056/NEJMoa022637.
At the core of the classic ketogenic diet is severely restricting intake of all or most foods with sugar and starch (carbohydrates). These foods are broken down into sugar (insulin and glucose) in our blood once we eat them, and if these levels become too high, extra calories are much more easily stored as body fat and results in unwanted weight gain. However, when glucose levels are cut off due to low-carb dieting, the body starts to burn fat instead and produces ketones that can be measured in the blood (using urine strips, for example).
Remember the low-fat diet craze? Back in the 1990s, we were told that swapping regular cookies and chips for those labeled "low fat" would be the ticket to easy weight loss and better health. Today, it's the opposite”a low-carb, high-fat eating plan called the ketogenic diet, or keto diet for short, is getting all the buzz. Celebrities like Halle Berry, Kim Kardashian, and Megan Fox are fans; more than 7 million Instagram posts have been tagged #keto; and upwards of 1 million people search "keto diet" on Google every month.

Drink lots of water. If you aren't consuming enough water then the organs in your body can't function properly. There is no point in eating right if your body can't do what it is supposed to with the foods. Drinking plain water can get tiring so I like to either use MiO in my water (this kind also helps to replenish electrolytes) or I'll turn to a detox water to change things up.
¢ High-protein ketogenic diet ” This method is a variant of the SKD. In a high-protein diet, you increase the ratio of protein consumption to 10 percent and reduce your healthy fat consumption by 10 percent. In a study involving obese men that tried this method, researchers noted that it helped reduce their hunger and lowered their food intake significantly, resulting in weight loss.11

All recipes include a color photo and complete nutritional analysis. Comes with a printable grocery list, snack list, tips for meal prepping and suggestions for substitutions.
Alcohol also tends to interrupt ketosis, since your liver will burn it preferentially before anything else. Your body treats alcohol like a toxin and like a fuel source, so your body will use it before it uses foods or the calories stored in your fat cells. While it won't necessarily œknock you out of ketosis, it does pause it until the alcohol is cleared from your system.
The electrolyte minerals are sodium, potassium, magnesium, and calcium, and you need all four. Sports drinks are full of sugars, and only have low amounts of these minerals, so it's best to avoid them. Instead, focus on vegetables that contain high amounts of these minerals, and make sure to salt your food to taste. You can also make an electrolyte drink that contains all of these minerals. Lite Salt or No Salt is available in the grocery store as a salt substitute, and contains potassium. Magnesium and calcium powders are available in health food stores and online.

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.

¢ Increasing muscle mass ” Jeff Volek, Ph.D., is a registered dietitian specializing in how a high-fat, low-carb diet can affect health and athletic performance. He's written many scientific articles on this topic, as well as two books, and he explains that ketones have a similar structure to branched-chain amino acids that can be useful for building muscle mass. Ketones spare these amino acids, leaving higher levels of them around, which can help promote muscle mass.
If this diet is so tough, then why has it been around since the 1920s? For starters, there's some evidence to suggest that ketogenic diets help regulate epilepsy, according to research in ISRN Pediatrics.Redox Biology reports the diet may benefit cancer patients. While it may be helpful for short-term weight loss, that wasn't the diet's original intention, and the jury's still out on its long-term effects.
It truly depends from person to person. While some may be able to stay in ketosis while consuming 80 grams of carbs, others may not be so lucky. Quite a lot of people within the population can go quite high in their carbohydrate consumption and stay in ketosis, granted they have no blood sugar dysregulation. The longer you have followed the keto diet, the more your metabolism remains in ketosis after a higher carb consumption.
First, let's start with the fact that most of the food in your cabinets just won't work anymore. They're not keto. Period. Lock them up, throw them out, donate them to a neighbor “ whatever you have to do to get them out of the house. In the first week, when you're craving carbohydrates, these foods will be the death of your ketogenic diet. Purge your pantry of carbohydrate foods!
If you're new to keto, watch out for hidden carbs. Generally, dairy products and nuts are a good way to meet your daily fat intake, but know that some of those items may contain more carbohydrates than you think. For example, yogurt topped with nuts may seem like a great keto-friendly snack, but a 5.3 ounce serving of plain yogurt has 12 grams of carbohydrates. Vanilla flavored yogurt has 24 grams of carbohydrates. Add an ounce of cashews, weighing in at nearly nine grams of carbs, and you're up to 21 to 33 grams of carbs for that snack, which could knock you out of ketosis. Be sure to read nutrition labels carefully and pay careful attention to serving sizes. Track foods using a keto-specific app like Senza or KetoDiet can help you stay within your recommended daily carb intake.
If you'd like to try intermittent fasting, it's best to start by gradually decreasing your feeding window. Start with not eating for a 12 hour stretch, including the time that you're sleeping. For example, you could stop eating at 8 in the evening, then have breakfast at 8 in the morning. Ultimately, you'll want to be mostly done with digestion by the time you go to bed, and not be hungry until late morning, so for most people a feeding window of 10am to 6pm would be a good goal.
There are two major ways fasting is beneficial for overall health. First, it gives the body a break from digestion. Digestion is a surprisingly stressful activity, and if there is a longer period of time where your body can focus on simply using the nutrients it's been given already without having to handle more, digestion tends to improve, as well as energy levels.
For any individual with diabetes, discussing dietary changes ” especially those as dramatic as the ones the ketogenic diet requires ” with your healthcare team is essential. Because carbohydrates are broken down into glucose in the blood, cutting carbohydrates from your diet could cause levels to crash rapidly depending on your current medication regimen. Such a change may require significant adjustments to medication and insulin to prevent dangerous side effects such as low blood sugar, called hypoglycemia. (8)
When you eat foods high in carbohydrates and fat, your body naturally produces glucose. Carbohydrates are the easiest thing for the body to process, and therefore it will use them first “ resulting in the excess fats to be stored immediately. In turn, this causes weight gain and health problems that are associated with high fat, high carbohydrate diets (NOT keto).

If you're a newbie planning your weekly keto diet plan, make the meals as easy as possible. A keto breakfast, for example, can take advantage of many classic breakfast foods, including eggs, bacon, sausage, and ham. Eggs are real winners in the keto world. They're extremely versatile, easy to cook, and have just half a gram of carbs but 6 g of protein and 5 g of fat.


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.


The keto diet isn't new, and it's been around for nearly a century. It was originally developed to treat people with epilepsy. In the 1920s, researchers found that raised levels of ketones in the blood led to fewer epileptic seizures in patients. The keto diet is still used today to treat children with epilepsy who don't respond well to anti-epileptic drugs.[2]

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).

If you'd like to try intermittent fasting, it's best to start by gradually decreasing your feeding window. Start with not eating for a 12 hour stretch, including the time that you're sleeping. For example, you could stop eating at 8 in the evening, then have breakfast at 8 in the morning. Ultimately, you'll want to be mostly done with digestion by the time you go to bed, and not be hungry until late morning, so for most people a feeding window of 10am to 6pm would be a good goal.
The Ketogenic Diet is unlike any other diet in the world in that it utilizes a high fat, minimal carbohydrate and moderate protein system in order to reset your body's ability to burn unwanted, stored fat. By restricting carbohydrates that are converted into glucose, you begin the journey to re-program your metabolism to start burning stored fats for fuel and energy instead of first burning beneficial glycogen that is stored in your muscles.
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.
You can use the Ketone Test Strips to test your ketone level. These are strips that use urine to measure excreted ketones. These are inexpensive and popular, but unfortunately highly inaccurate. They only measure the level of ketones that are excreted as waste, and not used by the body. They show that you're producing ketones, but not necessarily using them for energy.

Many people also experience cramping, notably in the feet and legs. Because of this, you'll want to consume extra electrolytes any time you are on a ketogenic plan. People who suffer with these symptoms refer to them as the Keto-Flu, and while it isn't like the real flu, the symptoms can knock you down until you get your electrolytes back in balance.

I find myself in the kitchen a lot more, but that's a good thing, especially since I'm gaining more energy and endurance from the diet. Since I live alone I've also invested in more plastic bags and containers. When I use one of the recipes I divide the finished product into the number of servings, eat one and bag the rest for the freezer or fridge.

Another third tip is snacking. Really important if you're a snacker and you are just starting your Ketogenic diet you'll probably need some form of snacks. Some of the best snacks for beginners include celery, nuts and nut-based hummus, cucumber. If you have more of a sweet-tooth, dark unsweetened chocolate is a great option, as is coconut or almond butter or even peanut butter.
¢ Type 2 Diabetes: This population has been studied heavily with the keto diet since it's technically as low-carb as you can get. While the research to date has been conducted in very small sample sizes, evidence suggests that an ultra-low-carb diet (like the keto diet) may help reduce A1C and improve insulin sensitivity by as much as 75 percent. In fact, a 2017 review found that a keto diet was associated with better glucose control and a reduction in medication use. Having said that, the authors cautioned that it was unclear whether the results were due to weight loss in general, or higher ketone levels.
¢ 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

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.

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.

In addition to helping with weight loss, the Keto Diet has been used to treat epilepsy, help with Type II diabetes polycystic ovary syndrome , acne , potential improvement in neurological diseases (Parkinson's and multiple sclerosis), certain types of cancer[15], and reduces the risk factors in both respiratory and cardiovascular diseases. Emerging studies are digging into its effects on Alzheimer's and other conditions as well.
