The Ketogenic Diet (Keto) is a very low-carbohydrate, high-fat, moderate-protein diet designed to shift the body’s metabolism into a state called ketosis, where fat becomes the primary fuel source instead of glucose.
Originally developed in the 1920s as a treatment for epilepsy, keto has since become a global phenomenon for weight loss, metabolic health, and lifestyle optimization. In 2025, it remains one of the most popular diets worldwide, though its adoption varies by region due to cultural, economic, and health factors.
The Science of Keto
- Macronutrient ratio:
- Carbohydrates: 5–10%
- Protein: 20–25%
- Fat: 65–75%
- Ketosis:
- Low carb intake → liver produces ketones (β-hydroxybutyrate, acetoacetate).
- Ketones replace glucose as the main energy source.
- Benefits (short-term):
- Weight loss
- Improved insulin sensitivity
- Reduced appetite
- Risks (long-term):
- Nutrient deficiencies
- Elevated LDL cholesterol (in some)
- Sustainability challenges
