The keto diet is a high fat diet. The goal is to get your body into ketosis and burn fat instead of carbs for fuel. The keto diet uses the following macronutrient ratios:
- 20-30% of calories from protein;

The ketogenic diet was developed in the 1920s to treat epilepsy in children. Recently, its popularity has increased due to the benefit of losing weight. However, a high-fat diet has other health benefits, such as:
- Balance of hormones;
- Reduced sugar cravings

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 find it easier to use ketones for energy than carbohydrates. As a result, 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 often caused by excessive sugar consumption.
