The ketogenic diet, commonly referred to as the keto diet, is a low-carb, high-fat diet that has become increasingly popular in recent years. The diet encourages the body to enter a state of ketosis, which is a metabolic process where the body burns fat for energy instead of carbohydrates.
How Does the Keto Diet Work?
The keto diet works by drastically reducing the intake of carbohydrates and increasing the consumption of fats. When carbohydrates are limited, the body begins to use stored fat for energy instead of glucose. This metabolic state is called ketosis. The diet typically consists of 75% fat, 20% protein, and 5% carbohydrates.
Benefits of the Keto Diet
1. Weight Loss: The keto diet has been shown to be effective in promoting weight loss and reducing body fat in both men and women.
2. Increased Energy: Many people report increased energy levels while on the keto diet, possibly due to the body’s increased use of fat for energy.
3. Improved Mental Clarity: Some people report improved mental clarity and focus while on the keto diet.
4. Reduced Inflammation: The keto diet has been shown to reduce inflammation in the body, which can have a number of health benefits.
