The ketogenic diet involves consuming a very low amount of carbohydrates and replacing them with fat to help your body burn fat for energy. Health benefits can include weight loss and lowering your risk for certain diseases.

 

The ketogenic diet (or keto diet, for short) is a low carb, high fat diet that offers many health benefits.

In fact, many studies show that this type of diet can help you lose weight and improve your health .

Ketogenic diets may even have benefits against diabetes, cancer, epilepsy, and Alzheimer’s disease (.

Here is a detailed beginner’s guide to the keto diet.

 

 

What are the basic rules for keto?

 

 

Keto basics

The ketogenic diet is a very low carb, high fat diet that shares many similarities with the Atkins and low carb diets.

It involves drastically reducing carbohydrate intake and replacing it with fat. This reduction in carbs puts your body into a metabolic state called ketosis.

When this happens, your body becomes incredibly efficient at burning fat for energy. It also turns fat into ketones in the liver, which can supply energy for the brain .

Ketogenic diets can cause significant reductions in blood sugar and insulin levels. This, along with the increased ketones, has some health benefits .

 

 

 

What do I eat on the keto diet?

 

 

There are several versions of the ketogenic diet, and what you eat depends on the type. They include:

  • Standard ketogenic diet (SKD): This is a very low carb, moderate protein and high fat diet. It typically contains 70% fat, 20% protein, and only 10% carbs .
  • Cyclical ketogenic diet (CKD): This diet involves periods of higher carb refeeds, such as 5 ketogenic days followed by 2 high carb days.
  • Targeted ketogenic diet (TKD): This diet allows you to add carbs around workouts.
  • High protein ketogenic diet: This is similar to a standard ketogenic diet, but includes more protein. The ratio is often 60% fat, 35% protein, and 5% carbs.

However, only the standard and high protein ketogenic diets have been studied extensively. Cyclical or targeted ketogenic diets are more advanced methods and primarily used by bodybuilders or athletes.

The information in this article mostly applies to the standard ketogenic diet (SKD), although many of the same principles also apply to the other versions.

 

 

8 Foods to Eat on a Ketogenic Diet

 

 

 

What can you eat on the keto diet? In this video, you'll learn about the healthiest foods you can eat while following a ketogenic diet.

 

 

 

What is ketosis?

 

 

 

Ketosis is a metabolic state in which your body uses fat for fuel instead of carbs.

It occurs when you significantly reduce your consumption of carbohydrates, limiting your body’s supply of glucose (sugar), which is the main source of energy for the cells.

Following a ketogenic diet is the most effective way to enter ketosis. Generally, this involves limiting carb consumption to around 20 to 50 grams per day and filling up on fats, such as meat, fish, eggs, nuts, and healthy oils .

It’s also important to moderate your protein consumption. This is because protein can be converted into glucose if consumed in high amounts, which may slow your transition into ketosis

Practicing intermittent fasting could also help you enter ketosis faster. There are many different forms of intermittent fasting, but the most common method involves limiting food intake to around 8 hours per day and fasting for the remaining 16 hours .

Blood, urine, and breath tests are available, which can help determine whether you’ve entered ketosis by measuring the amount of ketones produced by your body.

Certain symptoms may also indicate that you’ve entered ketosis, including increased thirst, dry mouth, frequent urination, and decreased hunger or appetite .

 

 

 

Can the keto diet help me lose weight?

 

 

 

 

A ketogenic diet is an effective way to lose weight and lower risk factors for disease .

In fact, research shows that the ketogenic diet may be as effective for weight loss as a low fat diet .

What’s more, the diet is so filling that you can lose weight without counting calories or tracking your food intake .

One review of 13 studies found that following a very low carb, ketogenic diet was slightly more effective for long-term weight loss than a low fat diet. People who followed the keto diet lost an average of 2 pounds (0.9 kg) more than the group that followed a low fat diet .

What’s more, it also led to reductions in diastolic blood pressure and triglyceride levels .

Another study in 34 older adults found that those who followed a ketogenic diet for 8 weeks lost nearly five times as much total body fat as those who followed a low fat diet .

The increased ketones, lower blood sugar levels, and improved insulin sensitivity may also play a key role .

 

 

 

Is the keto diet good for people with diabetes and prediabetes?

 

 

 

Diabetes is characterized by changes in metabolism, high blood sugar, and impaired insulin function .

The ketogenic diet can help you lose excess fat, which is closely linked to type 2 diabetesprediabetes, and metabolic syndrome .

One older study found that the ketogenic diet improved insulin sensitivity by a whopping 75% .

A small study in women with type 2 diabetes also found that following a ketogenic diet for 90 days significantly reduced levels of hemoglobin A1C, which is a measure of long-term blood sugar management .

Another study in 349 people with type 2 diabetes found that those who followed a ketogenic diet lost an average of 26.2 pounds (11.9 kg) over a 2-year period. This is an important benefit when considering the link between weight and type 2 diabetes .

What’s more, they also experienced improved blood sugar management, and the use of certain blood sugar medications decreased among participants throughout the course of the study .

 

 

 

What are the other benefits of the keto diet?

 

 

The ketogenic diet actually originated as a tool for treating neurological diseases such as epilepsy.

Studies have now shown that the diet can have benefits for a wide variety of different health conditions:

  • Heart disease. The ketogenic diet can help improve risk factors like body fat, HDL (good) cholesterol levels, blood pressure, and blood sugar .
  • Cancer. The diet is currently being explored as an additional treatment for cancer, because it may help slow tumor growth. .
  • Alzheimer’s disease. The keto diet may help reduce symptoms of Alzheimer’s disease and slow its progression .
  • Epilepsy. Research has shown that the ketogenic diet can cause significant reductions in seizures in epileptic children .
  • Parkinson’s disease. Although more research is needed, one study found that the diet helped improve symptoms of Parkinson’s disease .
  • Polycystic ovary syndrome. The ketogenic diet can help reduce insulin levels, which may play a key role in polycystic ovary syndrome .
  • Brain injuries. Some research suggests that the diet could improve outcomes of traumatic brain injuries .

However, keep in mind that research into many of these areas is far from conclusive.

 

 

 

What foods do I avoid on a keto diet?

 

 

Any food that’s high in carbs should be limited.

Here’s a list of foods that need to be reduced or eliminated on a ketogenic diet:

Keto tips and tricks

 

 

 

Although getting started on the ketogenic diet can be challenging, there are several tips and tricks that you can use to make it easier.

  • Start by familiarizing yourself with food labels and checking the grams of fat, carbs, and fiber to determine how your favorite foods can fit into your diet.
  • Planning out your meals in advance may also be beneficial and can help you save extra time throughout the week.
  • Many websites, food blogs, apps, and cookbooks also offer keto-friendly recipes and meal ideas that you can use to build your own custom menu.
  • Alternatively, some meal delivery services even offer keto-friendly options for a quick and convenient way to enjoy keto meals at home.
  • Look into healthy frozen keto meals when you’re short on time
  • When going to social gatherings or visiting family and friends, you may also want to consider bringing your own food, which can make it much easier to curb cravings and stick to your meal plan.

 

Tips for eating out on a ketogenic diet

 

 

Many restaurant meals can be made keto-friendly.

Most restaurants offer some kind of meat or fish-based dish. Order this and replace any high carb food with extra vegetables.

Egg-based meals are also a great option, such as an omelet or eggs and bacon.

Another favorite is bun-less burgers. You could also swap the fries for vegetables instead. Add extra avocado, cheese, bacon, or eggs.

At Mexican restaurants, you can enjoy any type of meat with extra cheese, guacamole, salsa, and sour cream.

For dessert, ask for a mixed cheese board or berries with cream.

 

 

Side effects and how to minimize them

 

 

 

 

Although the ketogenic diet is usually safe for most healthy people, there may be some initial side effects while your body adapts.

There’s some anecdotal evidence of these effects often referred to as the keto flu . Based on reports from some on the eating plan, it’s usually over within a few days.

Reported keto flu symptoms include diarrhea, constipation, and vomiting . Other less common symptoms include:

  • poor energy and mental function
  • increased hunger
  • sleep issues
  • nausea
  • digestive discomfort
  • decreased exercise performance

To minimize this, you can try a regular low carb diet for the first few weeks. This may teach your body to burn more fat before you completely eliminate carbs.

A ketogenic diet can also change the water and mineral balance of your body, so adding extra salt to your meals or taking mineral supplements may help. Talk to your doctor about your nutritional needs.

At least in the beginning, it’s important to eat until you’re full and avoid restricting calories too much. Usually, a ketogenic diet causes weight loss without intentional calorie restriction.

 

 

 

Does being on the keto diet have any risks?

 

 

While the keto diet has its benefits, staying on it in the long term may have some negative effects including risks of the following:

  • low protein in the blood
  • extra fat in the liver
  • kidney stones
  • micronutrient deficiencies

A type of medication called sodium-glucose cotransporter 2 (SGLT2) inhibitors for type 2 diabetes can increase the risk for diabetic ketoacidosis, a dangerous condition that increases blood acidity. Anyone taking this medication should avoid the keto diet .

More research is being done to determine the safety of the keto diet in the long term. Keep your doctor informed of your eating plan to guide your choices.

 

 

Are there supplements for a keto diet?

 

 

 

Although no supplements are required, some can be useful.

  • MCT oil. Added to drinks or yogurt, MCT oil provides energy and helps increase ketone levels. Shop for MCT oil online .
  • Minerals. Added salt and other minerals can be important when starting out due to shifts in water and mineral balance .
  • CaffeineCaffeine can have benefits for energy, fat loss, and performance .
  • Exogenous ketones. This supplement may help raise the body’s ketone levels .
  • CreatineCreatine provides numerous benefits for health and performance. This can help if you are combining a ketogenic diet with exercise .
  • Whey. Use half a scoop of whey protein in shakes or yogurt to increase your daily protein intake

 

 

Frequently asked questions

 

 

Here are answers to some of the most common questions about the ketogenic diet.

Can I ever eat carbs again?

Yes. However, it’s important to significantly reduce your carb intake initially. After the first 2 to 3 months, you can eat carbs on special occasions — just return to the diet immediately after.

Will I lose muscle?

There’s a risk of losing some muscle on any diet. However, protein intake and high ketone levels may help minimize muscle loss, especially if you lift weights .

Can I build muscle on a ketogenic diet?

Yes, but it may not work as well as on a moderate carb diet . For more details about low carb or keto diets and exercise performance, read this article.

How much protein can I eat?

Protein should be moderate, as a very high intake can spike insulin levels and lower ketones. Around 35% of total calorie intake is probably the upper limit.

What if I am constantly tired, weak, or fatigued?

You may not be in full ketosis or be utilizing fats and ketones efficiently. To counter this, lower your carb intake and revisit the points above. A supplement like MCT oil or ketones may also help .

My urine smells fruity. Why is this?

Don’t be alarmed. This is simply due to the excretion of by-products created during ketosis .

My breath smells. What can I do?

This is a common side effect. Try drinking naturally flavored water or chewing sugar-free gum.

I heard ketosis was extremely dangerous. Is this true?

People often confuse ketosis with ketoacidosis. Ketoacidosis is dangerous, but ketosis on a ketogenic diet is usually fine for healthy people. Speak to your doctor before starting any new diet.

I have digestion issues and diarrhea. What can I do?

This common side effect usually passes after 3 to 4 weeks. If it persists, try eating more high fiber veggies

What is the difference between a keto and a ketogenic diet?

People often refer to the ketogenic diet colloquially as the keto diet, so these terms refer to the same thing.

How much weight can I lose in 1 week on keto?

In the first week of the keto diet, the weight you lose is typically water weight. Anecdotally, people report losing about 1 lb (0.5 kg) to 10 lb or more (5 kg).

How Much Weight Can You Expect to Lose After 1 Week on Keto?

 

 

Entering ketosis

 

 

On keto, you strictly limit your carb intake, typically to 50 grams or fewer per day of total carbs, or 25 grams or fewer of net carbs, which are total carbs minus fiber.

For most people, carbs are the body’s primary source of energy. When you limit carbs, your body burns through the carb stores in your muscles and liver — called glycogen — typically within a few days

After this, your body switches to a metabolic state called ketosis, in which it uses ketones that are broken down from dietary fat or stored body fat, as its primary source of fuel

This shift, during which you burn through your glycogen stores and switch to using ketones, usually takes less than a week. However, for some people, it may take longer

Many people notice dramatic weight loss during this transition period after first starting the keto diet, but most of this is due to changes in water weight

 

 

Early weight loss is water weight

 

 

 

The glycogen stored in your muscles and liver is bound with water, typically at a ratio of 3 grams of water for each gram of glycogen

When you burn through these stored carbs, this water is excreted in your urine or sweat

As such, after starting keto, you may notice that you have to urinate more often and feel much thirstier than normal. You may also notice large weight losses, which are mostly water-weight losses

Depending on your size and how much water weight you’re carrying, this weight loss can vary. Anecdotally, people report losses within the first week of anywhere from 1 pound (0.5 kg) to 10 or more pounds (5 kg).

The larger you are, the more water weight you’re likely to lose after starting keto. Although, it’s unlikely that much of this initial weight loss is fat loss.

However, once you enter ketosis, it’s much easier to utilize your own stored fat for energy, which is one reason why the keto diet may be advantageous for weight loss

 

Is keto good or bad for you?

A ketogenic diet can be great for people who:

  • are overweight
  • have diabetes
  • are looking to improve their metabolic health

It may be less suitable for elite athletes or those wishing to add large amounts of muscle or weight.

It may also not be sustainable for some people’s lifestyles and preferences. Speak with your doctor about your eating plan and goals to decide if a keto eating plan is right for you.

The bottom line

While following the ketogenic diet, you reduce your carbohydrate intake and replace it with healthy fats. This can help your body to use fat for energy, encouraging weight loss and possibly reducing the chance of developing certain health issues.

That said, consult your doctor prior to engaging in the diet for an extended period of time, as it may have some side effects. More research is needed to understand its long-term effect on the body.
