Introduction
The keto diet has become one of the most popular weight-loss and health-focused eating plans in the world. Many people use it to lose weight, improve energy levels, and reduce cravings while enjoying satisfying foods.
Unlike traditional diets that focus on reducing calories, the ketogenic diet changes how your body gets energy. Instead of relying mainly on carbohydrates, your body begins to burn fat as its primary fuel source.
This guide explains everything beginners need to know about the keto diet, including its benefits, how it works, common mistakes, and practical tips for success.
What is Keto Diet?
The keto diet, short for ketogenic diet, is a low-carbohydrate, high-fat eating plan designed to put the body into a metabolic state called ketosis.
Normally, your body uses carbohydrates as its main source of energy. When you significantly reduce carb intake, your body starts breaking down fat into molecules called ketones. These ketones become the body's alternative fuel source.
A standard ketogenic diet typically includes:
- 70–80% calories from healthy fats
- 10–20% calories from protein
- 5–10% calories from carbohydrates
Foods commonly eaten on a keto diet include:
- Eggs
- Meat
- Fish
- Avocados
- Cheese
- Nuts and seeds
- Olive oil
- Leafy green vegetables
Foods usually avoided include:
- Bread
- Rice
- Pasta
- Sugary drinks
- Candy
- Most desserts
- High-carb fruits
The goal is to keep carbohydrate intake low enough for the body to remain in ketosis.
