Ketones

Ketones are organic compounds produced by the liver from fats when the body experiences a shortage of glucose or blood sugar.

How the body produces ketones

Under normal conditions, the body breaks down carbohydrates into glucose to supply energy for the cells. When the body runs low on glucose, such as during fasting or following a low-carbohydrate diet, the liver starts breaking down fats into small molecules called ketone bodies. The process of producing ketones is called ketogenesis.

Role of ketones in fitness, health, wellness and weight loss

Ketones can serve as an alternative source of energy for the brain and other tissues when glucose is in short supply, making them important during periods of fasting or exercise. In some cases, maintaining a state of ketosis (where the body is burning ketones for fuel instead of glucose) may have health benefits, such as improving blood sugar control and reducing inflammation. However, it is important to note that a state of ketosis is not necessary for weight loss or overall health and can be achieved through a variety of diets.
