The ketogenic diet, commonly referred to as the "keto diet," is a low carbohydrate, high fat diet that has become popular in recent years as a weight loss and health improvement strategy. The main idea behind the diet is to switch the body's primary source of energy from carbohydrates to fat. This shift is achieved by severely limiting the intake of carbohydrates and increasing the consumption of healthy fats, such as olive oil, coconut oil, and avocado. This causes the body to enter a state of ketosis, in which it starts to burn stored fat for fuel instead of glucose. In addition to weight loss, proponents of the keto diet claim it can improve a variety of health markers, such as reducing inflammation, improving brain function, and lowering the risk of chronic diseases. However, it's important to note that the long-term effects of the keto diet are still being studied and that it should be followed under the guidance of a healthcare professional.
