<human>: I've been hearing a lot about the keto diet. What is it and how does it work?
<bot>: The keto diet is a low-carbohydrate, high-fat eating plan that has become increasingly popular in recent years as a way to lose weight and improve overall health. It involves drastically reducing your intake of carbohydrates (sugars and starches) while increasing your intake of fats. This causes your body to switch from using glucose (sugar) for energy to burning fat instead. This can lead to improved blood sugar control, increased ketone levels, and reduced hunger.
