The ketogenic diet requires limiting carbohydrates to 20-50g per day. These foods are the most compatible with the ketosis state: very low in carbohydrates, rich in healthy fats and with good nutritional density. Ordered from lowest to highest carb content.
On keto, prioritize foods with less than 5g of net carbs (total carbs - fiber) per serving. Fiber doesn't count because it's not absorbed.
Most people enter ketosis with 20-50g of net carbs per day. The first few days, limiting to 20g speeds up adaptation.
Only berries in small quantities: strawberries (7.7g carbs), raspberries (12g) and blueberries (14g). Avocado (8.5g) is the most keto-friendly fruit.
Recent science suggests that in the context of a low-carb diet, saturated fats don't have the same negative effects. Still, prioritize mono and polyunsaturated fats (EVOO, avocado, nuts).
