Keto Diet: Everything That You Should Know


Following a specific diet has been in fashion for quite some time. Diets like the one meal a day diet, paleo, vegan, and keto diets are some of the most popular ones.

This article will discuss most of the essential things about the keto diet you need to know.

Keto Diet, also known as the ketogenic diet, is probably the most famous diet everybody wants to follow. People who talk in favor of the keto diet claim that they get faster results without the need for rigorous exercise.

It is probably one of the most strict diets that one can follow. This diet tries to focus on low carbs, high fats, and fiber. This type of diet is a plan for individuals that are looking to burn fat. 

All About Keto Diet

What Does A Keto Diet Mean?

The ketogenic diet is a low carbs diet. Therefore it is somewhat similar to the Atkins diet and low carbs diet. This diet follows the fundamentals[1] of reducing carbohydrates quickly while increasing fat quantity in your body.

Now, fats usually are miss interpreted as harmful. But the fats focused upon in the keto diet are probably the most crucial fats a person needs for energy.

When carbs reduce in your body, then your body gets into a state of ketosis. It is a metabolic state. Your body is pretty good at burning fat efficiently for energy at this stage.

With this, the fats in this state are converted into ketones in the liver. Then they supply energy to the brain. This diet also reduces[2] blood sugar levels and insulin levels in your body which is why it is an optimal diet for diabetic patients.

Also, one should ensure that they are only sticking to keto-friendly foods during their keto diet tenure. This will give you a better chance to succeed at the keto diet and help you achieve the desired fat levels.

Types Of Keto Diet

The keto diet is mistaken to be a one-of-a-kind diet with no subtypes, which is a myth. The keto diet has many substitutes. They are followed by people with different low-carb fat reduction needs.

  1. Standard Ketogenic Diet

    The standard ketogenic diet is the very basic[3] ketogenic diet that is followed vastly. This type majorly focuses on low carbs, high fat, and moderate protein.

    This is the diet where fat concentration can go up to as high as 70% and carbs concentration to as low as 10%.

  2. Cyclic Ketogenic Diet

    The cyclic ketogenic diet is a different type of ketogenic diet. It involves carbs refeeding periodically. This type of diet follows a pattern, for example, a few days of low carbs and a few days of high carbs.

    A clinical trial[4] showed that it could significantly drop weight when followed properly.

  3. Targeted Ketogenic Diet

    Target ketogenic diet is more of a line of ketogenic diet where it allows you to increase the consumption of carbs in your routine. But this increase should only be during the workout sessions.

    Besides the sessions, one cannot restrain from a low-carb diet. This type of diet is a good method to keep a person motivated to exercise more.

    Hence, the fat and the burned faster hands keep the body’s fitness intact.

  4. High Protein Ketogenic Diet

    This form of the ketogenic diet is a trusted version of the standard ketogenic diet. This diet majorly increases the intake and concentration of proteins instead of fats.

    Since all these types of diets are targeted to different types of people with different needs, the standard ketogenic diet and high protein ketogenic diet is the most common diet that is used by people widely.

    The other two categories of keto diets are considered more advanced versions of this type of diet. So this one is mainly used by bodybuilders and athletes.

    The study[5] conducted on 17 obese men showed that a high-protein and low-carb ketogenic diet could help in suppressing hunger more than other moderate carb and high-protein nonketogenic diets.


Usually, the human body uses carbs as a fuel for energy purposes but in the state of ketosis, the body uses fats instead of carbs as a fuel for the same purpose.

It is considered a rather healthier version of fuel consumption. The reduced consumption of carbs limits the supply of sugar or glucose in your body.

Due to this, the body has to turn to another source of energy for the cells. The key process generally is very hard to attend to. However, falling on a ketogenic diet can help you attain ketosis in the right way.

Keto diets reduce the consumption[1] of carbs in your body where you usually eat eggs, fish, nuts, meats, and healthy oils.

Eating all these types of foods increases fat in your body alongside protein but reduces carbs. This further enters you into the ketosis state helping you reduce fat faster than ever.

Proteins are usually kept in moderate amounts because they can be converted into glucose whenever the body requires it. If proteins are kept in a higher amount then that will nullify the effect.

It further will not help you reduce fat in the body at the pace this diet offers. Ketosis can also be entered by following an intermittent fasting method

Though this method can be more drastic for your health. Intermittent fasting follows the concept of limiting food consumption and fasting for longer periods in a day.

Now to measure whether you have entered the state of ketosis, you can use breath, urine, and blood testers to figure out. On a general note, decreased hunger, frequent urination, increased thirst, and dry mouth can work as symptoms[6] of ketosis.

Losing Weight With Keto Diet

The Keto diet is considered probably the most famous and effective[7] weight loss diet. It has many health benefits.

It may help you fight diseases with the lowest risk to your health. Keto diets are considered as much effective as low-fat diets with more efficiency.

This keto diet also is more of a linear diet where you do not have to worry about low food intake and calorie consumption.

Rather, the keto diet probably fills you up more than any other diet that you may follow. It also helps you reduce diastolic blood pressure and triglyceride levels.

This is the unwanted type of fat in your body that is used as fuel for energy purposes.

Having said all that, one should not consume everything during a keto diet. There are several food items that you should avoid during the keto diet.

Keto Diet And Diabetes

Diabetes is a condition where your insulin functions are impaired due to which blood sugar levels increase which further is very harmful to a human being.

People often with obese figures tend to suffer from such conditions. Now we know a ketogenic diet is directly effective for weight loss and decreasing fat quantity in your body.

Therefore it is closely related to diabetes, prediabetes, and metabolic syndrome. This syndrome means blood sugar levels with high blood pressure and low levels of good cholesterol.

Alongside, you witness higher triglyceride levels and excess fat around the waist. Such conditions can cause harmful heart diseases.

According to a cohort study[8], the ketogenic diet is productive in improving insulin sensitivity by an enormous margin. It also has been reported to reduce the concentration of hemoglobin A1C in type 2 diabetic females and improve blood pressure management.

This diet has very effectively reduced weight in people at a drastic pace which is an important note to take considering the relation of weight with diabetes.

One can also regularly consume keto fruits even if you are on a strict keto diet.

Keto Diet Health Benefits

Keto Diet has been proven effective for many medical conditions. These are discussed as follows:

  • Combating Heart disease

    Heart diseases are generally related to body fat and cholesterol levels. Keto Diet might help reduce the risk factors relating to body fat, HDL cholesterol levels, blood sugar and pressure.

    This way it might help one to combat heart diseases and prevent them, as per the study[9].

  • Cancer Remedy

    Keto Diet is a pretty healthy diet plan which can help one in many ways. Specifically, this certain diet in combination with various therapies might have the potential for reducing the growth of cancer tumours, concludes the study[10].

  • Helpful In Alzheimer’s disease

    Alzheimer’s disease, till now, isn’t a curable neurological disease. But it has been reported that the keto diet can help reduce[11] and slow down the progression and symptoms of Alzheimer’s disease.

  • Brain Injuries

    This diet reportedly helps reduce and improve the ill effects of brain injuries in rats and might have the potential to be effective for humans as well, quotes the study[12].

There are many benefits of the keto diet if practised in the right way. Besides fat reduction and the mentioned remedies, it can also help combat and prevent Parkinson’s disease[13] and polycystic ovary syndrome[14].

Side Effects Of Keto Diet

Like any other phenomenon, person and solution, this diet has flaws[15]. It does come with the flaws that make it not so flawless a diet plan.

Hence, you should follow a keto diet with certain precautions and prerequisites after consulting a doctor or dietician. Otherwise, it may incorporate some side effects. It may turn out bad for you.

The side effects of this diet are all compiled as an illness itself. It is called Keto Flu. This Flu usually includes symptoms[6] like diarrhea, constipation, and vomiting.

These may or may not be coupled with poor energy, nausea, sleep issues, decreased performance, and increased hunger.


The keto diet all over is a good diet to follow for quick results. It may help you reduce fat. It simultaneously also prevents health problems.

These problems may ultimately turn catastrophic. But the keto diet is a promising way to avoid major neurological and heart problems. Do keep in mind that it does come with a few drawbacks.

So you should, in all cases, consult your doctor or dietician before continuing to follow this diet.
