The keto diet is a high fat diet. The point is to bring your body into ketosis and burn fat instead of carbohydrates for fuel. The keto diet uses the following macronutrient ratios:
- 20-30% calories from protein;
- 70-80% of calories from healthy fats;
- 5% or less calories from carbohydrates.
The ketogenic diet was developed in the 1920s to treat epilepsy in children. Recently, its popularity has grown due to the benefits of losing weight. However, a high-fat diet has other health benefits, such as:
- Hormone balance;
- Decreased cravings for sugar
- Blood sugar balance;
- Improving mood and increasing energy levels;
- Reduction of inflammation;
- Improving mental clarity.
What are ketones?
In ketosis, the liver converts fatty acids into ketone bodies or ketones. These by-products become a new source of energy for your body. There are three main ketones: acetone, acetoacetate, beta-hydroxybutyrate.
Our brains and other organs use ketones for energy more easily than carbohydrates. Therefore, most people experience increased mental clarity, good mood and reduced hunger. These molecules also have antioxidant and anti-inflammatory effects. They can help reverse and repair cell damage that often causes sugar overeating.
