In fact, over 20 studies show that the ketogenic diet can help in losing weight and improve the health.

Ketogenic diets may even have advantages against diabetes, cancer, epilepsy and Alzheimer’s disease

A detailed beginner’s guide to the keto diet is mentioned.

Ketogenic Diet – Meaning

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

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

The body becomes incredibly efficient at burning fat for energy when ketosis happens. Ketosis also turns fat  in the liver into ketones, which can supply energy for the brain.

Ketogenic diets can bring massive reductions in blood sugar and insulin levels and along with the increased ketones, it has numerous health benefits

 A low-carb, high-fat diet is called a keto diet which lowers blood sugar and insulin levels, and shifts the body’s metabolism away from carbs and towards fat and ketones.

Types of Ketogenic Diets

There are several types of the ketogenic diet, including:

  • Standard ketogenic diet (SKD) is a very low-carb, moderate-protein and high-fat diet. It generally has 75% fat, 20% protein and only 5% carbs.
  • Cyclical ketogenic diet (CKD) involves intervals of higher-carb refeeds, such as 5 ketogenic days followed by 2 high-carb days.
  • Targeted ketogenic diet (TKD) is a diet which allows to add carbs during workouts.
  • High-protein ketogenic diet is same as that to a typical ketogenic diet, but it includes more protein. The ratio in between is often 60% fat, 35% protein and 5% carbs.

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

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

There are several types of the keto diet but the standard (SKD) version is the most researched and most suggested.

Ketogenic Diets Can Help in Losing Weight

A ketogenic diet is an productive way to lose weight and reduce risk factors for disease.

In fact, research shows that the ketogenic diet is considered to be far superior to the often suggested low-fat diet

The diet is so filling that weight loss can be  without the need of counting calories or tracking the food intake

A study found out that people who are on a ketogenic diet lost weight  2.2 times more than those on a calorie-restricted low-fat diet. Triglyceride and HDL cholesterol levels were also improved

Another study found out that people on the ketogenic diet lost weight almost 3 times more than those on the diet suggested by Diabetes UK

There are various reasons why a ketogenic diet is superior to a low-fat diet, including the increased protein intake, which provides several benefits.

Ketones which are increased, lower levels of blood sugar and insulin sensitivity is improved may also play a key role


A ketogenic diet can help in losing much more weight than a low-fat diet which often happens without be hungry.

Diabetes and Pre-diabetes – Ketogenic Diets

Changes in metabolism, high blood sugar and impaired insulin function is characterized in Diabetes

The ketogenic diet can help in losing excess fat, which is linked closely  to type 2 diabetes, prediabetes and metabolic syndrome

A study found that the insulin sensitivity improved in ketogenic diet by a percentage of 75%

People with type 2 diabetes found in another study that 7 of the 21 participants were able to stop consuming all diabetes medications

In one more another study, the ketogenic group lost about 24.4 pounds (11.1 kg), compared to 15.2 pounds (6.9 kg) in the higher-carb group. This is a vital benefit when considering the connection between weight and type 2 diabetes

Additionally, around 95% of the ketogenic group were also able to stop or decrease the diabetes medication, in comparison to 62% in the higher-carb group.


The ketogenic diet can help in boosting the insulin sensitivity and cause fat loss, leading to more health benefits for people with type 2 diabetes or pre-diabetes.

Keto – Other Health Benefits

For treating neurological diseases such as epilepsy the ketogenic diet was actually originated as a tool.

Some studies have now shown that the diet can have advantages for a broad variety of different health conditions:

  • The ketogenic diet’s risk factors in heart diseases can be improved like body fat, HDL cholesterol levels, blood pressure and blood sugar.
  • The ketogenic diet is currently being used to treat various types of cancer and slow growth of tumor.
  • The keto diet may help in reducing symptoms of Alzheimer’s disease and slow its progression.
  • Studies have shown that the ketogenic diet in epileptic children can cause massive reductions in seizures.
  • The ketogenic diet helped improve symptoms of Parkinson’s disease which had been found in one study.
  • The ketogenic diet can help in reducing levels of insulin, which may play a important role in polycystic ovary syndrome.
  • After brain injury in one animal study it has been found that the diet can reduce concussions and aid recovery.
  • Acne can also be improved with lower insulin levels and eating less sugar or processed foods may help improve acne.

However, it has to be kept in mind that research into many of these areas is far from conclusive.

Many health benefits, especially with metabolic, neurological or insulin-related diseases may be provided by a ketogenic diet.

Frequently Asked Questions

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

1. Can I ever eat carbs again?

Yes. However, it is vital to significantly decrease the carb intake initially. After the first 2–3 months, carbs can be eaten on special occasions — just return to the diet immediately after.

2. Will I lose muscle?

Losing some muscle on any diet is a risk associated. However, the high protein intake and high ketone levels may help reduce muscle loss, especially if lifting weights.

3. Can I build muscle on a ketogenic diet?

Yes, but it might not work as well as on a diet which is moderate-carb .

4. Do I need to refeed or carb load?

No. However, a few higher-calorie days may be useful every now and then.

5. How much protein can I eat?

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

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

If feeling tired then may be the full ketosis or be utilizing fats and ketones is not efficient. To counter this, lower the carb intake and re-visit the points mentioned above. A supplement like MCT oil or ketones may also be helpful.

7. My urine smells fruity. Why is this?

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

8. My breath smells. What can I do?

Breath smelling is a common side effect. Try to  drink naturally flavored water or chew sugar-free gum.

9. I heard ketosis was extremely dangerous. Is this true?

People are often confused with ketosis and ketoacidosis. The former is natural, while the latter occurs only in uncontrolled diabetes.

Ketoacidosis is menacing, but the ketosis on a ketogenic diet is perfectly normal and healthy.

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

Digestion issues and diarrhea  are common side effects and usually passes after 3–4 weeks. If it persists, more high-fiber veggies should be tried. Magnesium supplements can also be helpful with constipation.

A Ketogenic Diet Is Great, but Not for Everybody

A ketogenic diet can be more useful for people who are overweight, diabetic or looking to improve their metabolic health.
