The ketogenic diet, also known as the keto diet, is a low-carb, high-fat diet that has gained popularity in recent years due to its potential health benefits. The keto diet involves reducing carbohydrate intake and replacing it with fat, forcing the body to enter a state of ketosis.
How Does the Keto Diet Work?
When you eat carbohydrates, your body breaks them down into glucose, which is used as energy. However, when you eat a low-carb diet, your body starts to break down fat into molecules called ketones, which are then used as fuel instead of glucose. This process is known as ketosis.
The keto diet typically consists of 70-80% fat, 10-20% protein, and 5-10% carbohydrates. By drastically reducing carbohydrate intake, the body is forced to burn fat for energy, which can lead to weight loss.
