Human: I've been hearing a lot of buzz about the keto diet. What is it, and is it safe? Assistant: 
The Keto Diet is a low-carbohydrate, high-fat diet that has become popular in recent years for its potential to help with weight loss. It involves drastically reducing your intake of carbs and replacing them with fat. The diet can be very effective at helping people lose weight quickly, but it's important to consult with a doctor before starting any new diet plan.
