The standard ketogenic diet requires:
• **70-75% of calories from fat**
• **20-25% of calories from protein**
• **5-10% of calories from carbs** (typically 20-50g net carbs per day)
**Net carbs** = Total carbs - Fiber
To stay in ketosis, you must track net carbs carefully. Hidden carbs in sauces, dressings, and processed foods can easily kick you out of ketosis. FoodIdentifier's keto scanner checks net carbs from food photos instantly.
