You can eat high-fat fruits like avocados and coconuts on keto. You can also eat low-carb (and low GI) fruits such as berries, honeydew melon, and lemons in moderation. Definitely look up the carb content of all fruit using nutrition apps and chose fruits with less than 5 g of carbs per cup. Any carbs you eat add up to your total carb intake which should be under 20 to 30 g per day.
