Low-carb high fat diet (LCHF). Find your low carb options to keep your body in ketosis, which is a fat-burning metabolic state that occurs when you limit your carbohydrates intake. Without the carbs, your body burns through fat for energy instead of glucose. Ketones are the compounds that are produced, and their presence means your body is in ketosis, or a fat-burning state. Eat things like avocado, eggs, steak, keto bulletproof coffee with grass fed unsalted butter and organic coconut oil or MCT oil. Find here the best low carb options near you in London.
