The classic keto diet is a foundational type of ketogenic diet, serving as the origin from which other variations have been derived.
It was developed in 1923 by Dr. Russell Wilder at the renowned Mayo Clinic, initially for treating epilepsy in children.
Studies indicate that the keto diet was also utilized by the Greeks and Phoenicians as early as 500 BC to manage epileptic seizures.

Defining the Classic Keto Diet
The classic keto diet is a dietary approach aimed at those seeking significant and rapid weight loss.
It drastically restricts carbohydrate intake, with a daily consumption ranging between 20 to 50 grams.
In contrast to the low carbohydrate intake, the diet emphasizes a high daily consumption of healthy fats, while protein intake remains at a moderate level.
Macronutrient Values in the Classic Keto Diet
As previously mentioned, the metabolic breakdown of meals within the classic keto diet relies on fats, proteins, and carbohydrates, with the following ratios:
- Healthy Fats: 70% (70% of daily calorie intake comes from fats)
- Carbohydrates: 5% (referring to net carbs)
- Proteins: 25%
With this distribution, an individual consuming 2500 calories daily would intake:
- 208 grams of fat
- 125 grams of protein
- 30 grams of carbohydrates
Calculating calorie intake from each macronutrient:
- Total calories from fat: 2500 x 70% = 1750
- Total calories from protein: 2500 x 20% = 500
- Total calories from carbohydrates: 2500 x 10% = 250
Allowed Foods in the Classic Keto Diet
Foods permitted in the classic keto diet adhere to the calorie guidelines mentioned above.
Due to the significant reduction in carbohydrates (20-50 grams daily), individuals may experience the "keto flu."
This term is used because the symptoms resemble those of the common flu and typically last between 4 days to a week.
Stages of the Classic Keto Diet
The classic keto diet progresses through four stages, during which the body attempts to eliminate the adverse effects of a high-carbohydrate diet.
The process culminates in the body adapting to utilizing fats and breaking them down to extract ketones as the primary energy source instead of glucose.

FAQs
What is the Keto Diet for Weight Loss?
The keto diet is a dietary approach that focuses on minimizing carbohydrate intake and increasing healthy fat consumption.
This forces the body to utilize fats for energy, facilitating its functions.
While various types of keto diets exist, the classic keto diet is considered the most effective due to its strict carbohydrate restriction, leading to faster adaptation and fat burning, resulting in accelerated weight loss.
How Much Weight Can You Lose in a Week on the Keto Diet?
There is no fixed amount or rate of weight loss per week on the keto diet.
It depends on several factors, including the body's adaptation speed, the presence of underlying health conditions, the ability to exercise, adherence to dietary guidelines, and the duration of ketosis.
However, during the first week, significant weight loss occurs due to water loss as glycogen stores deplete.
The average loss ranges between 2 to 3 kilograms.
In the second and third weeks, the rate decreases to around 0.5 to 1 kilogram per week.
While weight loss on the keto diet slows down in the long run, the lost weight is less likely to be regained after exiting ketosis.
Conclusion
The classic keto diet serves as the foundation of the ketogenic approach but is stricter than other variations, such as the targeted keto diet or the cyclical keto diet.
These alternatives allow for a higher daily carbohydrate intake and are often followed by individuals engaged in strenuous physical activities or those with high physical demands, such as bodybuilders.
