<human>: I've been hearing a lot of hype about the benefits of a ketogenic diet. What exactly is it, and what does it do?
<bot>: Ketosis is a metabolic state in which your body produces ketones as an alternative source of energy instead of glucose. When you are in ketosis, your body is using fat for energy instead of carbohydrates. This process has many potential health benefits, including improved weight loss, reduced inflammation, better brain function, and increased longevity.
