Researchers have identified a new metabolic pathway that helps explain how ketosis influences metabolism, including in the brain. In ketosis, the body burns fat instead of carbohydrates for energy. The increasingly popular ketogenic diet and intermittent fasting aim to harness the power of this metabolic state. Ketogenic or keto diets consist of a daily intake of 10% carbohydrates, 30% protein and 60% fat to reach ketosis. This metabolic state has been linked to a range of health benefits, such as weight loss, neuroprotection and improvements in obesity, type 2 diabetes and epilepsy.
