Here is a detailed guide on how the keto diet works and how to maintain it for a healthy lifestyle.
All You Need to Know About Ketogenic Diets: Health Benefits, Side Effects, And More
Who Discovered the Keto Diet?
In the 1990s, Robert Atkins, a cardiologist, first proposed a ketogenic diet or keto diet.
He has been experimenting with low-carb diet methods for a long time, since the 70s, and published his findings in a new book.
His book became an instant hit after its release.
The keto diet became famous as a low-carb diet for fitness enthusiasts, especially celebrities and actors all over the world.
Due to the constant endorsement and somewhat constant results, the Keto diet slowly became a mainstream option for low carb diets and is still popular among people.
What is a Keto Diet in Reality?
The human body usually uses carbohydrates to produce body fuel.
But, in the keto diet, the body uses fat for fuel. You replace the high carb diet with low carb diets filled with loads of fat.
The body has three sources to burn fats- carbohydrates, fats, and proteins.
The human body prefers carbohydrates, which are easier to digest and convert to energy.
In general, humans often take a High carb diet to get more fuel for their body.
If you opt for a very high-carb diet, your body will not use the body fat to get energy. Instead, it stores the fat, resulting in excessive weight and excess body fat.
The same things also happen if you opt for a low-fat diet.
But, when you opt for a low carbohydrate diet like the keto diet, your body is forced to adjust to the high-fat diet.
As your meal mostly comprises high fats and fewer amounts of carbs, the body is forced to burn the fat and gain energy.
This, in turn, prevents fat storage inside your body, resulting in weight loss.
How Does The Keto Diet Work?
You already know that the basis of a ketogenic diet is ketosis. In this diet, you reduce the amount of carb intake and restrict it to 20-50grams.
Then, the missing 70% of carbs are replaced with fats or fatty food to force the body to perform ketosis.
Besides that, protein intake is also controlled. This ensures that the body is prohibited from using protein as fuel.
The main principle of the ketogenic diet is the principle of ketosis. Ketosis is the procedure of ketone burning.
When your body digests the high fat inside the liver with enzymes, Ketone is produced.
This Ketone is then burned in excessive body fat and weight gain. Cells produce energy to provide fuel for the body.
That means, with ketosis, your body uses the fat for fuel instead of glucose.
The blood sugar level also has a close relation with body weight. Your blood sugar level has a direct impact on your hunger.
If the level is higher, you will feel hungry more often. With a keto diet, you can control the carb amount in your body.
Hence, your blood sugar level automatically goes down.
As a result, you do not feel hungry more often. In other words, your appetite decreases, and you feel fuller for a long time.
This allows your body to burn body fat instead of storing it.
Types of Keto Diets
In general, the ketogenic diet involves going on very low-carb diets instead of a low-fat diet to force the body into ketosis and burning the high-fat present in the body to produce energy.
But, the key to a successful keto diet is to measure the calorie intake as per the ratio.
But, following a strict ketogenic diet may not be easier for everyone.
Hence, different versions of the keto diet exist.
But, all of these follow the same principle of reducing the overall carb intake to burn excess body fat.
1) Standard Keto diet or SKD
The standard ketogenic diet, or SKD, is the most traditional keto diet in the world.
This diet is often used for diabetic patients or epileptic patients. Those with insulin sensitivity can also get great results by following the SDK.
The main principle of this low carb diet is to put the body in a steady ketosis state.
In a standard Ketogenic diet, you need to get 70%-75% fat, 5-10% of carbs, or not more than 50 grams per day alongside 20% protein.
The recommended fat foods or keto foods are filled with unsaturated fats and monounsaturated fats or healthy fats.
In addition, you can add foods like nuts and seeds, fish, avocados, olive oil, and coconut oil.
These high fat food items are beneficial for people with high blood sugar.
These fast food items help your body produce more ketones and allow you to take a few more grams of carbs without stopping the ketosis method.
One Of the easiest ways to learn if your keto diet is working is to check your breath.
Your diet is in the right direction if your breath smells fruity or metallic.
2) Targeted ketogenic diet or Cyclical diet
The targeted ketogenic diet is great for those unable to tolerate the steady and continuous ketosis phase.
For such people, a short carb boost amidst a low-carb diet is necessary as they require more glucose due to certain activities they perform.
In this diet, you follow the ketogenic diet for three to five days a week and take three to two days off from it to give your body more benefits.
3) Modified Atkins diet or High protein keto diet
This diet is somewhat a mixture of the keto diet and the excess protein diet.
In this diet, you maintain a low carb diet without adhering to the strict principles of the keto diet.
Hence, you have increased protein intake (25%-20%), 60-65% of fat, and 10% of carbs.
4) Modified Keto
Another diet for high sugar patients or those who have insulin sensitivity is the modified keto diet. It is ideal for those who cannot opt for a strict keto regimen due to health issues.
This diet allows you to eat 15% carbohydrates, 55% fat, and 30% protein.
Hence you can add food items like whole grains, legumes, and fruits besides nuts and seeds to get that carb kick.
Despite being a modified diet, it can also help you lose weight.

But, those who can follow the diet perfectly can decrease the amount of “statin” medicines or even may get off the medication with a healthy cholesterol level.
But, you need to measure your food and calorie intake. In this diet, you should not eat high fat foods laden with saturated fats, especially animal products and meat.

Hence, your body turns to burn fat to gain energy, resulting in rapid weight loss by burning down excess body fat.

1) It may increase kidney or liver disease
Do you suffer from fatty liver disease or kidney disease?
Then probably going on a keto diet is not a good idea.
The distinct eating habits of the keto diet may increase the chance of developing kidney stones.
But this can be solved by introducing vegetable protein into your diet.
Interestingly, the diet will work fine if you have existing kidney problems. But, in some cases, it may backfire.

The ketogenic diet will improve your condition if you suffer from nonalcoholic fatty liver disease.

2) The long-term safety issues
One of the main concerns with a high-fat diet is its safety issues.
In addition, studying dietary plans is often tricky and complicated as it is impossible to monitor every minute detail.

If you have experienced one of these symptoms within one or two weeks of starting a keto diet, consult your physician.
After that, you may need to stop it altogether.
4) High chances of LDL cholesterol
The Keto diet decreases the cholesterol level, especially the LDL or low-density lipoprotein cholesterol.

Keto Diet is indeed expensive.
However, it also increases your carbon footprint as you buy more processed foods. Hence, try to include natural items from local sources.
