What is a keto diet, and other common questions –

The Ketogenic Diet, or keto diet for short, is a low-carb, high-fat diet in which you eat only enough fat to meet your body’s energy needs, and adequate amounts of protein and fiber to maintain and build muscle. Ketogenic diets may help you lose weight by making your body burn fat for fuel. As you get more used to the diet, you may find it more sustainable. It may be a good way to lose weight and keep it off, and there are some research studies that show that it may be effective for people with Type 2 diabetes.

Keto diet is a diet designed for weight loss. Instead of counting calories, the diet revolves around filling the body with fat, the body burns fat to make energy and the fat goes away. The basic premise of the diet is to restrict carbohydrates from the diet, replace the carbohydrates with high-fat foods like meats, fats and oils, and also change the amount of protein consumed. The keto diet is a low carb, moderate protein and high fat diet. Instead of eating carbs, you eat the fats and proteins. Such a diet is known as ketogenic diet, or keto diet.

Is a keto diet the cure to weight gain? A keto diet is a low carb diet where you restrict your carbs to 20 grams per day. This typically is achieved by eating around 50 grams of fat per day. Benefits are weight loss and a reduction in your risk for Type 2 diabetes. It has been proven that people who eat a ketogenic diet have a reduction in their risk of developing type 2 diabetes..

What exactly is a ketogenic diet?

The keto diet is a low-carbohydrate diet that causes ketosis. To accomplish this, a low-carbohydrate diet is required. Most keto diets include a moderate protein content and a high fat content, but this varies.

We prefer the word “variable” for fat intake because, as long as you have extra weight to shed, you may be fuelled by the fat you consume or by your own fat reserves. As individuals gain experience with the keto diet, they may adjust their fat intake to suit their preferences for flavor and satiety, as well as to achieve their weight reduction or other health objectives.

The goal is to discover a mixture that makes carbohydrate restriction long-term maintainable.

What exactly is ketosis?

When you consume little carbs, your body goes into ketosis, which allows it to keep functioning.


Carbohydrates are one of the body’s two primary fuel sources. We can also burn fat for energy, but the brain does not have the ability to do so. Instead, when you consume a low-carb diet, fat is converted to ketones in the liver, which are then released into the bloodstream. This is an excellent source of mental energy.

Ketosis is the process of using fat to power the whole body, including the creation of ketones. Ketosis is healthy and natural under normal conditions, such as when it occurs as a consequence of a low-carb (“keto”) diet or when fasting.

Ketosis, on the other hand, may be a symptom of insulin insufficiency in some situations – most frequently type 1 diabetes – and the ketones can then increase to potentially dangerous levels.

Is it safe to follow a ketogenic diet?

A ketogenic diet is generally considered to be extremely safe. However, you may need to make additional preparations or adaptations in the following three scenarios:

  • Are you using diabetic medication, such as insulin? Find out more.
  • Are you taking blood pressure medication? Find out more.
  • Are you a mother who is breastfeeding? Find out more.

If you’re not in one of these circumstances, a keto diet will probably work for you without any adjustments.

It’s worth noting that there are many misconceptions and misunderstandings regarding keto that both children and adults are afraid of. So, if you’re worried about anything specific, have a look at this website.


In conclusion, a ketogenic diet is generally extremely safe. However, be mindful of the three conditions listed above, such as diabetes or blood pressure medication, or breastfeeding.


What are the signs that your body is in ketosis?


Any of the following symptoms may suggest that you’re in ketosis:

  • Appetite decreases and energy levels rise.
  • Thirst and urination have increased.
  • “Keto breath,” which may be more noticeable to others than it is to you. Find out more.
  • You may have dry mouth or a metallic taste in your tongue.

You may assess your degree of ketosis using one of three techniques in addition to these signs and symptoms:

Here’s how to tell whether you’re in ketosis:


What foods are allowed on the keto diet?


Real low-carb foods such as meat, fish, eggs, veggies, and natural fats should be consumed (like olive oil or butter). For novices, a basic guideline is to consume meals with less than 5% carbohydrates (numbers above).

Is a ketogenic diet good for your kidneys?

Yes. People often inquire about this because they believe a high-protein diet is detrimental to the kidneys. This concern, however, stems from two misunderstandings:

  1. A ketogenic diet is rich in fat and low in protein.
  2. Excess protein is not a problem for those with normal renal function.

As a result, there’s no need to be concerned. More information on low-carb diets and renal function may be found in our evidence-based guide.


In conclusion, a ketogenic diet is safe for your kidneys.


Is it safe to go into ketosis if you have diabetes?

A keto diet that leads to ketosis is a highly effective therapy for type 2 diabetes reversal.

A keto or low-carb diet may help people with type 1 diabetes manage their blood sugar levels substantially. Insulin injections are required for people with type 1 diabetes at all times, although at much lower dosages on keto. They must be careful not to take too low a dosage and get ketoacidosis, or too high a dose and develop hypoglycemia.

On a keto diet, individuals with type 1 and type 2 diabetes may need to reduce their medication quickly to prevent hypoglycemia. As a result, anybody using blood sugar-lowering medication should talk to their doctor before starting a low-carb diet. On our locate a doctor map, you’ll discover a selection of low-carb specialists.


Bottom line: For individuals with diabetes, a keto diet may be an effective option for curing type 2 diabetes and controlling type 1. However, it’s critical to alter medicines as required.


On the keto diet, what may you drink?


The short answer is that water, like coffee and tea, is wonderful and carb-free (without sugar, of course). It’s also OK to have a glass of wine now and again.

How many carbohydrates can you consume while being in ketosis?

This varies, but generally speaking, staying below 20 net carbohydrates per day is a good idea.

Some individuals who are not insulin resistant – for example, slender, youthful people who exercise frequently – may tolerate up to 50 grams of carbohydrates each day. One research found that healthy volunteers could maintain ketosis at 50 grams per day and move in and out of ketosis at a rate of up to 100 grams per day.

Obese and insulin-resistant people, on the other hand, need to eat a lot less carbs. To guarantee success with ketosis, we suggest 20 grams of net carbohydrates each day.

Is it healthy to follow a ketogenic diet if you have high cholesterol?

In general, a keto diet improves cholesterol profile by decreasing triglycerides and increasing HDL cholesterol (the so-called “good” cholesterol) while having no effect on LDL cholesterol.

A tiny percentage of individuals, however, may have excessive total or LDL cholesterol. There are no quality studies to establish if this is harmful or safe in this particular group, therefore the answer is unknown. However, if you are one of the rare people whose cholesterol rises to dangerously high levels, you should talk to your doctor and perhaps take measures to lower it just to be cautious.

Here’s how to deal with high cholesterol when on a keto or low-carb diet.

Another article discusses how to decrease LDL cholesterol while on a low-carb or ketogenic diet.

Is it possible to be in ketosis and not lose weight?

Yes. If that’s the case, have a look at our weight-loss advice.

When you’re in ketosis, how long does it take you to feel like you’re in it?

It may last anywhere from a day or two to a week or longer. Those with greater insulin resistance (e.g., people with type 2 diabetes) take longer to enter ketosis, while young and slim people do so much faster. In addition, the amount of carbs consumed at the start of the study may have an impact. Those who started with less carbohydrates will likely enter ketosis quicker than those who started with more carbs.

On a keto diet, can I eat fruit?

Fruits, unlike non-starchy vegetables, are frequently thought to be healthful, although they are really extremely rich in carbohydrates and sugar. As a result, most fruits should be avoided while following a rigorous keto diet.


Certain berries, on the other hand, are an exception and may be consumed in modest quantities. Blackberries, raspberries, and strawberries are the greatest options, with 5-6 grams of carb per 100 grams (312 ounces).

Most other fruits, including blueberries, have twice or triple the quantity of carbohydrates, as seen in this list of the top and worst carb-containing fruits.

Remember that berries don’t offer any nutrients that can’t be found in veggies and other low-carb meals, so they’re completely optional on the keto diet. In fact, if you’re insulin resistant, it’s possible that you’d be better off without them.

How long can a person stay on a ketogenic diet?

Enjoy it for as long as you wish.

Although there are no long-term studies of individuals in ketosis that have lasted decades, there is no indication that it is hazardous. For decades, experienced physicians have cared for ketosis patients, and evolutionary theories indicate that certain cultures have lived in ketosis for much longer.

While none of this shows it is safe scientifically, we prefer to think about it from the opposite side. Where can I get proof that it is harmful? So yet, we haven’t seen any.

Is it possible to follow a ketogenic diet as a vegetarian or vegan?

Many non-meat eaters may benefit from a keto diet, depending on the other foods they consume.

A lacto-ovo vegetarian consumes both dairy and eggs, whereas a lacto-vegetarian consumes both dairy and eggs. Pescatarians are a subgroup of vegetarians who consume fish but eschew chicken and other meat.

Although it is possible to follow the ketogenic diet as a vegetarian, it may be difficult, particularly when initially starting out. Our scientifically validated guide may assist you in following a low-carb or keto vegetarian diet.

Several well-balanced, nutritious meat-free meals are included in our keto vegetarian meal plan.

A vegan ketogenic diet is much more difficult. Vegans must depend on a mix of grains, legumes, and seeds to obtain all of the necessary amino acids their bodies need since they avoid any animal products. Due to the increased carbohydrate content of these meals, keeping below 20 carb grams per day may be difficult. However, a vegan moderate low-carbohydrate diet is possible. Our low-carb vegan lifestyle guide may assist you in getting started.

Is it okay for me to eat dairy while on a keto diet?

Dairy is nutrient-dense and, in many instances, may be included into a ketogenic diet. However, whether or not you should consume dairy depends on your particular health objectives and how you react to it.

Higher dairy consumption, for example, has been related to fat reduction and decreased diabetes risk in many studies, but it has also been linked to higher insulin levels. Many individuals find that reducing their dairy intake helps them lose weight.

Avoid high-carb foods that are usually considered “healthy,” such as nonfat milk and nonfat yogurt, if you’re on a low-carb diet. Instead, concentrate on the following high-fat options:

  • Butter
  • Cream
  • yogurt with sour cream
  • creme fraiche
  • Cheese
  • Plain whole-milk yogurt, Greek yogurt, or kefir are all good options.

What is the difference between a low-carb and a ketogenic diet?

Keto is a highly stringent low-carb diet that places an even greater focus on limiting protein consumption and depending mainly on fat for energy.

Most individuals will be in ketosis regardless if they follow a rigorous low-carb diet on a regular basis. A keto diet, on the other hand, adjusts things even further to ensure that it’s working and, if wanted, to go even deeper into ketosis.

Keto may be described as a very low-carb diet.

When it comes to low-carb, how low-carb is low-carb?

Why am I not in a state of ketosis?

The most frequent cause for failure to enter ketosis is this: Too many carbohydrates

It may be difficult to estimate the amount of carbohydrates in a meal correctly. We handle all the calculations for you if you adhere to our recipes, so there’s no guesswork. If you’re making your own meals or snacks, try lowering the carbohydrates even further to see if it affects your ketones.

Some individuals worry that eating too much protein would prevent them from reaching ketosis. While this may happen to some individuals, it seems to be a rare occurrence, and scientific investigations indicate it is not a significant clinical problem. As far as we can tell, it seems to be more of a problem when starting a ketogenic diet and for people who are more insulin resistant.

See our complete guide for additional information. Please keep in mind that the quantities that individuals can tolerate while remaining in ketosis vary from person to person. Here’s the first in a three-part blog article on how our colleague Bjarte Bakke discovered how to achieve optimum ketosis: Why aren’t you in ketosis?

Should you strive for high ketone levels if you want to lose weight quickly?

Both yes and no. Weight reduction is aided by eating less carbohydrates and fasting intermittently, which lowers insulin and raises ketones.

Adding additional fat to increase ketone levels, on the other hand, does not result in weight reduction. Drinking “exogenous” ketone supplements or supplementing with MCT oil to increase ketone levels don’t work. These techniques may delay weight reduction by giving an alternate fuel source to burn instead of body fat.

Focus on limiting carbohydrates, eating enough protein, and utilizing fat as required for flavor and satiety if you want to reduce weight. When you’re hungry or need to boost your performance, use MCT oil or exogenous ketones (unrelated to weight loss). Find out more.

When is the best time to check your ketone levels?

It’s best to measure at the same time every day for comparative reasons. It’s simpler to compare results from day to day if you measure in the morning before eating.

However, numbers may fluctuate throughout the day, with many reporting their lowest numbers in the morning and somewhat larger numbers in the evening. So, if you need astonishingly high figures, take measurements in the nights instead. Be aware that your ketone levels do not differentiate between the burning of food fat and the burning of stored fat, and that greater ketone levels are unlikely to help your health or weight reduction.

Is it safe to eat keto during pregnancy?

Based on the experiences of individuals who have done it and physicians who have treated patients on a keto diet during pregnancy, a keto diet seems to be safe during pregnancy. It may also be beneficial if you have gestational diabetes.

However, since there have been no scientific research on the topic, there is a dearth of concrete information. Unless there are significant health advantages to adopting a keto diet in your particular situation, it may be prudent to take care and strive for a more modest low-carb diet during pregnancy. Before making any major changes, you should consult with your healthcare practitioner. Find out more.
