Ketosis is a natural metabolic process that happens when the body doesn't have enough carbohydrates to convert into energy. During ketosis, the liver breaks down stored fat into molecules called ketones. Your body uses these ketones as fuel instead of glucose from carbohydrates. Ketosis is a key concept behind the popular ketogenic diet.

Examples of Ketogenic Diet

Ketogenic diets involve drastically reducing the intake of carbs and replacing them with fats, so that the body goes into a metabolic state called ketosis. In addition to weight loss, ketogenic diets may help reduce inflammation, improve insulin resistance, and boost brain function.

Benefits and Risks

Ketosis can be beneficial for weight loss, as well as for people with type 2 diabetes, metabolic syndrome, and neurological disorders. However, ketosis can also have risks, such as dehydration, constipation, bad breath, nutrient deficiencies, and potential liver and kidney damage if sustained over a long period of time. It's important to consult with a healthcare professional before starting a ketogenic diet or any other weight loss program.
