<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?
<bot>: The keto diet is a low-carb, high-fat diet that has become increasingly popular in recent years. It involves drastically reducing carbohydrate intake and replacing them with fats and proteins. This helps to reduce insulin levels, which can lead to weight loss. Additionally, research shows that following the keto diet may also help improve blood sugar control and cholesterol levels.
