Nutritionists, including the Good Housekeeping Institute's own Jaclyn London, MS, RD, CDN, remain more skeptical. The diet's aim of inducing ketosis — a metabolic process where the body uses fat instead of carbs for energy — can backfire because this plan takes a lot of willpower. Plus, any weight you may lose while on it can return when you stop. RDs and other experts like U.S. News and World Report agree that Mediterranean-style eating plans have more research behind them and produce better, more long-lasting results.  

A survey in 2005 of 88 paediatric neurologists in the US found that 36% regularly prescribed the diet after three or more drugs had failed, 24% occasionally prescribed the diet as a last resort, 24% had only prescribed the diet in a few rare cases, and 16% had never prescribed the diet. Several possible explanations exist for this gap between evidence and clinical practice.[34] One major factor may be the lack of adequately trained dietitians, who are needed to administer a ketogenic diet programme.[31]
The keto diet also appears to help induce autophagy, which helps clear damaged cells from the body, including senescent cells that serve no functional purpose but still linger inside tissues and organs. In animal studies when rats are put on the ketogenic diet, autophagic pathways are created that reduce brain injury during and after seizures. (21)
These are all keto related questions that a person looking into the ketogenic diet for the first time will have, and I’ve put together a comprehensive list of answers to these questions and more in my 3 Day Keto Kickstart Plan & Keto frequently asked questions linked to below.  If you’re new to keto I recommend starting there, and if you use that Keto Kickstart meal plan as written, I am confident that you will get into ketosis and be losing weight within 3 days of starting.  I’m excited for you!!!!

One downside to a ketogenic diet for weight loss is the difficulty maintaining it. “Studies show that weight loss results from being on a low-carb diet for more than 12 months tend to be the same as being on a normal, healthy diet,” says Mattinson. While you may be eating more satiating fats (like peanut butter, regular butter, or avocado), you’re also way more limited in what’s allowed on the diet, which can make everyday situations, like eating dinner with family or going out with friends, far more difficult. Because people often find it tough to sustain, it’s easy to rely on it as a short-term diet rather than a long-term lifestyle.
The day before admission to hospital, the proportion of carbohydrate in the diet may be decreased and the patient begins fasting after his or her evening meal.[19] On admission, only calorie- and caffeine-free fluids[37] are allowed until dinner, which consists of "eggnog"[Note 8] restricted to one-third of the typical calories for a meal. The following breakfast and lunch are similar, and on the second day, the "eggnog" dinner is increased to two-thirds of a typical meal's caloric content. By the third day, dinner contains the full calorie quota and is a standard ketogenic meal (not "eggnog"). After a ketogenic breakfast on the fourth day, the patient is discharged. Where possible, the patient's current medicines are changed to carbohydrate-free formulations.[19]
Grass-fed meat is a must for keto dieters. Compared to grain-fed, grass-fed meats are higher in omega-3 fatty acids, which have a range of health benefits including improving heart health, lowering levels of inflammation, and even easing symptoms of depression. High-quality poultry also packs a nutritional punch, with plenty of iron, selenium, zinc, and B vitamins. Dark meat, which is higher in fat, is particularly good for the keto diet.
A keto diet has shown to improve triglyceride levels and cholesterol levels most associated with arterial buildup. More specifically low-carb, high-fat diets show a dramatic increase in HDL and decrease in LDL particle concentration compared to low-fat diets.3A study in the long-term effects of a ketogenic diet shows a significant reduction in cholesterol levels, body weight, and blood glucose.

You’re transitioning. Your body is equipped to process a high intake of carbs and a lower intake of fat. Your body needs to create enzymes to be able to do this. In the transitional period, the brain may run low on energy which can lead to grogginess, nausea, and headaches. If you’re having a large problem with this, you can choose to reduce carb intake gradually.

The way that being on the keto diet makes you lose weight is by keeping insulin levels low. Insulin is a fat storage hormone that is released to help shuttle energy from the food you eat into your cells. This diet is known to be one of the best ways, besides fasting of course, to drop your insulin levels and low insulin is what is usually associated with fat loss. However, there is a misconception out there that your insulin will only go up with carbs. Protein can also spike your insulin levels and if you eat enough fats in one sitting, especially the wrong type of fats like trans fats, then that can spike your insulin levels as well.
The keto diet doesn't discriminate against all you cheese lovers. While we're often told to avoid dairy because of its high fat content, this is precisely what makes it an ideal keto food group. As usual, stick to the low-carb options and avoid anything that adds unnecessary calories via flavorings or sugars. Listed in order of lowest to highest carb content per 1-ounce serving, the best dairy products for the keto diet include:
In the absence of glucose, which is normally used by cells as a quick source of energy, the body starts to burn fat and produces ketone bodies instead (it’s why the keto diet is often referred to as the ketone diet). Once ketone levels in the blood rise to a certain point, you enter into a state of ketosis — which usually results in quick and consistent weight loss until you reach a healthy, stable body weight. See this keto diet review, a before and after trying keto for 30 days.

Carbs in fruits and veggies do count, but you don’t add up the carbs and sugar. Sugar is already included in the carbs – it’s just listed separately on labels because some people want to see a breakdown of how much of the carbs are sugars (versus other, complex carbs). If it says 2g carbs and 2g sugar, it means there is 2g total carbs and all of them are sugar (in this case).

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:
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.

Aude, Y., A. S, Agatston, F. Lopez-Jimenez, et al. “The National Cholesterol Education Program Diet vs a Diet Lower in Carbohydrates and Higher in Protein and Monounsaturated Fat: A Randomized Trial.” JAMA Internal Medicine 164, no. 19 (2004): 2141–46. doi: 10.1001/archinte.164.19.2141. jamanetwork.com/journals/jamainternalmedicine/article-abstract/217514.
Lunch: pat dry chicken and cut into cubes. Lightly (!) salt and pepper. Heat a skillet over medium heat, once hot add coconut oil and fry chicken cubes until brown from all sides. Remove chicken, and add crushed garlic, curry paste and fish sauce to pan. Stir until fragrant and remaining oil in pan and curry paste are well combined. Then add coconut milk and whisk until well combined. Simmer and reduce sauce until desired consistency (1-3 minutes). Pour sauce over chicken and sprinkle with sesame seeds. Serve with baby spinach.
The ketogenic diet is calculated by a dietitian for each child. Age, weight, activity levels, culture, and food preferences all affect the meal plan. First, the energy requirements are set at 80–90% of the recommended daily amounts (RDA) for the child's age (the high-fat diet requires less energy to process than a typical high-carbohydrate diet). Highly active children or those with muscle spasticity require more food energy than this; immobile children require less. The ketogenic ratio of the diet compares the weight of fat to the combined weight of carbohydrate and protein. This is typically 4:1, but children who are younger than 18 months, older than 12 years, or who are obese may be started on a 3:1 ratio. Fat is energy-rich, with 9 kcal/g (38 kJ/g) compared to 4 kcal/g (17 kJ/g) for carbohydrate or protein, so portions on the ketogenic diet are smaller than normal. The quantity of fat in the diet can be calculated from the overall energy requirements and the chosen ketogenic ratio. Next, the protein levels are set to allow for growth and body maintenance, and are around 1 g protein for each kg of body weight. Lastly, the amount of carbohydrate is set according to what allowance is left while maintaining the chosen ratio. Any carbohydrate in medications or supplements must be subtracted from this allowance. The total daily amount of fat, protein, and carbohydrate is then evenly divided across the meals.[37]

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.[55]
All grains, even whole meal (wheat, rye, oats, corn, barley, millet, bulgur, sorghum, rice, amaranth, buckwheat, sprouted grains), quinoa and white potatoes. this includes all products made from grains (pasta, bread, pizza, cookies, crackers, etc.) sugar and sweets (table sugar, HFCS, agave syrup, ice creams, cakes, sweet puddings and sugary soft-drinks).
Like nuts, seeds are great for a snack on the go. But they're also a fun, crunchy addition to a salad. In addition to being low-carb and high-fat, seeds also offer a good serving of protein, which will help keep you full throughout the day. Listed in order of lowest to highest carb content per 1-ounce serving, the best seeds for the keto diet include:
Use fat as a lever.  We’ve been taught to fear fat, but don’t! Both keto and low carb are high fat diets. Fat is our source of energy as well as satiety. The key to understand, though, is that fat is a lever on a low carb or keto diet. Carbs and protein stay constant, and fat is the one you increase or decrease (push the lever up or down) to gain or lose weight, respectively. So if your goal is weight loss, eat enough fat to be satisfied, but there’s no need to “get your fats in” once you’re satisfied.

This is so incredibly helpful! My doctor told me I’m at high risk for Diabetes and that he would bring me back in 3 months for repeat labs. He told me to go on a low carb diet and without realizing it, I ended up doing the keto diet. I was determined to lower my carb intake even more and I haven’t had over 20g net carbs since I started. This is a lifesaver. Thank you!

Still, it can be hard to get enough fat when you first start this diet. Butter, nuts, coconut and olive oils, and fatty cuts of meat are all on the menu. However, don't go overboard with polyunsaturated fats like soybean, corn, or sunflower oil. Keto dieters who increase their intake of those fats often end up with gastrointestinal distress that causes them to jump ship.
Most condiments below range from 0.5–2 net carb grams per 1–2 tablespoon serving. Check ingredient labels to make sure added sugar is not included, which will increase net carbs. (Stevia and erythritol will become your go-to sweeteners because neither raise your blood sugar — combine for a more natural sweet taste and, remember, a little goes a long way!)

My Husband and I started doing Keto July 2018. We got over weight after we got out of the Marine Corps. It has been hard to workout because I became disabled, but my diet was not good. After our friend Amber recommended your site and support group, we found a lot of helpful information to get us started on a successful journey. So far it’s been one month and we have lost 18 pounds each!

Although many hypotheses have been put forward to explain how the ketogenic diet works, it remains a mystery. Disproven hypotheses include systemic acidosis (high levels of acid in the blood), electrolyte changes and hypoglycaemia (low blood glucose).[19] Although many biochemical changes are known to occur in the brain of a patient on the ketogenic diet, it is not known which of these has an anticonvulsant effect. The lack of understanding in this area is similar to the situation with many anticonvulsant drugs.[56]
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.[57] 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.[56]

This plan is very high on protein. I’ve learned that high healthy fat is what’s needed, not high protein.. as I am now kicked out of ketosis due to high protein intake (insulin’s fault). Given the fact i didn’t eat a bowl of salad per day (my tummy doesn’t digest salad well at all – i get bloated), but i do eat broccoli (i don’t get bloated from those strangely enough), cauliflower, asparagus, mushrooms… tomatoes (rarely, though). So, my question is… are you in ketosis following the menu you’ve presented? I’m 5 months into Keto and the last 3 weeks i am not in ketosis. My carb intake is 20-30g… but my protein is pretty high.
How many calories should I eat a day? A calorie is an amount of energy that a particular food provides. Consuming more calories than needed will result in weight gain, consuming too few will result in weight loss. How many calories a person should eat each day depends on a variety of factors, such as age, size, sex, activity levels, and general health. Read now
Hi Cyn, The numbers are general guidelines but will vary depending on many factors, such as activity level, insulin resistance, weight and more. There is no single magic number, just conventional recommendations that are a good starting point. I will have a macro calculator coming soon that will help determine what is best for each person, but even then it’s an approximation. The only way to know for sure is to test. If keto is your goal, it’s usually best to start lower and then see if you can stay in ketosis when increasing.
Certain studies suggest that keto diets may “starve” cancer cells. A highly processed, pro-inflammatory, low-nutrient foods can feed cancer cells causing them to proliferate. What’s the connection between high-sugar consumption and cancer? The regular cells found in our bodies are able to use fat for energy, but it’s believed that cancer cells cannot metabolically shift to use fat rather than glucose.

The beauty of salmon is that you can cook it with marginal interference. A simple sauce of butter, lemon juice, chopped garlic, and some salt and pepper will go a long way to enhancing the natural flavor of the salmon. Drizzle the sauce over 4-6 oz portions of fish, bake at 450F for 5 minutes per 1/2″ thickness of fish. In another bowl, toss the asparagus with olive oil, salt, and pepper, spread it out evenly on a cookie sheet, and roast in the oven at 450 for 20 minutes. Easy dinner (with leftovers if you plan ahead) that’s full of nutrition, protein, and healthy fat, while keeping your carbs low. Get the recipe and instructions
When you’re eating the foods that get you there (more on that in a minute), your body can enter a state of ketosis in one to three days, she adds. During the diet, the majority of calories you consume come from fat, with a little protein and very little carbohydrates. Ketosis also happens if you eat a very low-calorie diet — think doctor-supervised, only when medically recommended diets of 600 to 800 total calories.
A recent systemic review and meta-analysis of randomized controlled trials comparing the long-term effects (greater than 1 year) of dietary interventions on weight loss showed no sound evidence for recommending low-fat diets. In fact, low-carbohydrate diets led to significantly greater weight loss compared to low-fat interventions. It was observed that a carbohydrate-restricted diet is better than a low-fat diet for retaining an individual’s BMR. In other words, the quality of calories consumed may affect the number of calories burned. BMR dropped by more than 400 kcal/day on a low-fat diet when compared to a very low-carb diet.
Here are a few of the most common side effects that I come across when people first start keto. Frequently the issues relate to dehydration or lack of micronutrients (vitamins) in the body. Make sure that you’re drinking enough water (close to a gallon a day) and eating foods with good sources of micronutrients. To read more on micronutrients, click here >
The first modern study of fasting as a treatment for epilepsy was in France in 1911.[12] Twenty epilepsy patients of all ages were "detoxified" by consuming a low-calorie vegetarian diet, combined with periods of fasting and purging. Two benefited enormously, but most failed to maintain compliance with the imposed restrictions. The diet improved the patients' mental capabilities, in contrast to their medication, potassium bromide, which dulled the mind.[13]
Hi Patti, It’s up to you if you want to go by weight or by volume. I include both for convenience. Some people don’t want to weigh all their food, though weighing is definitely more accurate. The volumes listed are based on how a food is normally served, so for iceberg lettuce it would be chopped, not minced. It sounds like you’re weighing anyway, so in this case just use the weights instead (they are shown in grams in parentheses next to the volumes). Hope this helps!
In spite of the scientific evidence and real-life testimonials, not everyone is recommended to go on the ketosis diet. This highly specialized, extremely meticulous diet plan is suited to a particular dieter profile, and may also be harmful to some without the guidance of a doctor. But if performed correctly, the very low-calorie diet may be the only way for you to experience considerable, life-changing weight reduction.
You’re very welcome, Judy! I’m glad it’s helpful. If you are keto (as opposed to low carb), unfortunately peaches would not allow you to stay in ketosis. You can check my keto food list to help determine what is keto friendly. Of course, there are worse things than fresh fruit 🙂 but in the end our bodies still see the sugar. That being said, it doesn’t mean you sabotaged the whole day. Just pick up again – you got this!! (And for next time, try some fresh berries in moderation when you’re craving fruit.)
Bread probably isn’t the first thing that comes to mind when you think about the ketogenic diet because it’s generally full of carbs. But, if you replace your store-bought bread with a homemade keto bread recipe, it can fit seamlessly into your keto low-carb, high-fat diet. How does bread even become keto-friendly? With almond flour, a lot of eggs, cream of tartar, butter, baking soda and apple cider vinegar.

The easiest macro to calculate in the ketogenic diet is fat. Once you've got your carbs and protein set, simply fill the rest of your daily calorie needs with fat sources. If you find yourself wanting to gain a bit of weight, add approximately 500 calories, or 55 grams. If you want to lose weight, cut down on your fat intake by 200-500 calories, or 22-55 grams.
As a bonus, I’m making this amazing meal plan – and other keto meal plans – available in my MealPrepPro app!  So, if you’ve been wondering what the hype is all about and you want me to some of the heavy work for you by providing a fresh, customizable keto meal plan each week, then make sure you test drive my MealPrepPro app. The app is FREE to try and available right now to download on iPhone and iPad.
Following a ketogenic diet puts your body into a state of “ketosis,” which is a metabolic state that occurs when most of the body’s energy comes from ketone bodies in the blood, rather than from glucose from carbohydrate foods (like grains, all sources of sugar or fruit, for example). This is in contrast to a glycolytic state, where blood glucose (sugar) provides most of the body’s fuel (or energy).

First reported in 2003, the idea of using a form of the Atkins diet to treat epilepsy came about after parents and patients discovered that the induction phase of the Atkins diet controlled seizures. The ketogenic diet team at Johns Hopkins Hospital modified the Atkins diet by removing the aim of achieving weight loss, extending the induction phase indefinitely, and specifically encouraging fat consumption. Compared with the ketogenic diet, the modified Atkins diet (MAD) places no limit on calories or protein, and the lower overall ketogenic ratio (about 1:1) does not need to be consistently maintained by all meals of the day. The MAD does not begin with a fast or with a stay in hospital and requires less dietitian support than the ketogenic diet. Carbohydrates are initially limited to 10 g per day in children or 20 g per day in adults, and are increased to 20–30 g per day after a month or so, depending on the effect on seizure control or tolerance of the restrictions. Like the ketogenic diet, the MAD requires vitamin and mineral supplements and children are carefully and periodically monitored at outpatient clinics.[48]
