Ketogenic Diet - Weight Loss Guide

A ketogenic diet (so-called keto diet) is a diet that consists of low carbohydrates and relatively high amounts of fats and proteins in it, which in turn offers a lot of health benefits that help a person significant weight loss.

Research has proved that the ketogenic diet is beneficial for diseases like Diabetes or Cancer (Joshi Shilpa1 and Viswanathan Mohan2, 2018).

How do these ketogenic diets work to provide all these benefits to the human body?

The ketogenic diet reduces the carbohydrate intake in the body and replaces it with fats. A reduction in the number of carbs puts the body in a state called Ketosis .

It is a process in which the body does not have enough carbohydrates to burn to produce energy. Your body starts burning fats in place of carbohydrates, which helps you lose weight.

A ketogenic diet has some pros and cons. According to some studies, it is beneficial for cardiac problems; However, some research shows it is high in saturated fats.

Its long-term use may increase some people's LDL (low-density lipoproteins). As a result, it increases the risk of cardiovascular disease and some other heart problems like a heart attack or a stroke.

In addition to that, the ketogenic diet is not permissible for pregnant women, and a Keto diet is not allowed for nursing moms because low carbs can be life-threatening for them. Furthermore, people having liver, respiratory or cardiac diseases should avoid the ketogenic diet.


Ketogenic diets have been widely used worldwide for their weight loss properties. Keto-friendly foods are proven to help patients lose almost 2kg more weight than the other low-fat diets do in one year.

Almost all Ketogenic diets start with a restriction in the number of carbohydrates to less than 20 to 50 g/d (10% of energy intake) for about every two months. The period where there is an increase in weight loss starts at about 5 months because of the Ketogenic diet. Keto involves less calorie intake, which helps in weight loss.

Effectiveness: Ketogenic diets can help lose weight effectively and in a significantly less amount of time. If we eat a high number of foods with a fat percentage and limit our body's carbohydrate intake to like 20-50 grams per day, we can lose 10 pounds or more in only one month. If keto meal is used for a long time, it may help a person live a longer life.


Proper evidence proves that Ketogenic diets help lose fats faster than any other diet.

According to a systematic review of 13 RCTs of ketogenic vs. low-fat diets (N = 1577, 61% women, BMI 30 to 43 kg/m2), those who relied on ketogenic diets lost 0.9 kg more than those who relied on low-fat diets at 12 to 24 months. In another study in 2007, it was proved that a low-carb diet caused more weight loss than any other low-fat diet.

According to Diabetes UK’s dietary guidelines, it was found that the low-carb group lost 15.2 pounds(which is 6.9 kg) in comparison to the low-fat group, which lost only 4.6 pounds (which is 2.1 kg) so over 3 months. The low-carb diet resulted in weight loss 3 times more than a low-fat diet.


Ketogenic diets can work without any exercise. During ketogenic more fats are burned instead of sugars, so there is no need to exercise because enough fats are already being burned.

Most personal trainers and nutritionists do not recommend working out or strenuous exercise during a ketogenic diet. It depends on you if you want to lose weight in a rapid period or you want to lose stubborn body fats (18 Reasons Why the Keto Diet Can Help You Lose Weight and Burn Fat, 2022).

Serious muscle loss in possible during keto. There are cases when the patient is very severely overweight, so combining a ketogenic diet and high exercise would not be a good option. In this particular case, the patient is first asked to reduce enough weight so that he can safely combine their ketogenic diet with exercise.

There’s a risk of muscle loss if a person does not workout while following a ketogenic diet because of the higher body fat levels. The leaner you are, the higher the risk of muscle loss is.


It is important to make planning on keto, which drives our body into the state of ketosis in less time. Proper planning helps you to burn fats rapidly instead of carbs, so ensuring more fats are burnt increases the weight loss. It takes a body almost 3 days to enter the process of ketosis. While following the diet, most of the patient's calories come from body fat.

The doctor has recommended taking almost 600-800 total calories per day in a ketogenic diet.

If you want the ketogenic diet plan to working effectively, you should always follow the diet plan issued either by a nutritionist or your doctor. You should eat more meats, fats, and oils. On the other hand, you have to consume significantly fewer non-starchy vegetables. protein also gives some calories in a ketogenic diet, almost about 1 gram per kilogram of body weight.

A proper diet plan should be made based on one’s body requirements, and the nutritionist should be aware of any health problems faced by the patient. The doctor continuously checks (health history) if the person has any respiratory or cardiac issues before making a food chart for the patient.

Every person has a different metabolism, so the results from the ketogenic diet might vary from person to person, so the doctor should make the diet plan based on every person’s requirements to enhance the process of weight loss through the diet.


These are the foods that you should eat while following a ketogenic diet. Eating these foods regularly might enhance or speed up the process of weight loss. It would help if you always were careful of your calorie intake. It is always advised to follow a diet plan specifically made for you by your nutritionist.
