Human: I've been hearing a lot of buzz about the keto diet. What exactly is it and is it a good way to lose weight? Assistant: 
Keto is a low-carb, high-fat diet that has been gaining in popularity as a way to help people lose weight. It involves drastically reducing your intake of carbs, which can be found in breads, pasta, rice, and other starchy foods. Instead, you eat more fat, such as fatty meats, butter, cheese, avocados, olives, and nuts. This helps to kickstart your metabolism and burn fat faster than normal. The goal is to reach ketosis, where your body switches from burning glucose (carbohydrates) for energy to burning fats instead.
