The ketogenic diet (keto diet) is a low-carbohydrate, high-fat eating plan designed to shift your body into a metabolic state called ketosis. In ketosis, your body burns fat for fuel instead of carbohydrates.
Originally developed to help manage epilepsy, the keto diet has become widely popular for weight loss, blood sugar balance, and improved energy levels.
What Is the Ketogenic Diet?
The keto diet dramatically reduces carbohydrate intake and replaces it with healthy fats. This reduction in carbs puts your body into ketosis.
Typical Macronutrient Breakdown:
- 🥑 70–75% fat
- 🍗 20–25% protein
- 🥦 5–10% carbohydrates
Most people limit carbs to around 20–50 grams per day.
How Ketosis Works
Normally, your body uses glucose (from carbohydrates) as its main energy source. When carbs are restricted:
- Blood sugar levels drop
- Insulin levels decrease
- The body begins breaking down fat
- The liver produces ketones for energy
This metabolic shift is called ketosis.
