This calculator turns your daily calorie target and chosen keto strictness level into a daily net carb limit, shown in both grams and kcal. It also converts that limit into an equivalent number of rice bowls, helping people starting a ketogenic or low-carb diet visualize a real-world portion. All calculations run instantly in your browser and nothing is sent to a server.
How to use
- Enter your daily target calorie intake (kcal).
- Choose a strictness level: Strict Keto (5%), Moderate (10%), or Mild Low-Carb (20%).
- See your daily net carb limit in grams and kcal, plus its equivalent in bowls of white rice.
FAQ
- How are the carb ratios determined?
- Strict Keto uses 5% of total calories from carbs, Moderate uses 10%, and Mild Low-Carb uses 20%. Carbohydrates are converted at 4 kcal per gram.
- What is the rice bowl comparison based on?
- It assumes one bowl of white rice (about 210g) contains roughly 70g of net carbs, and converts your calculated carb limit into that unit.
- Is my data saved anywhere?
- No. All calculations happen locally in your browser and nothing is sent to or stored on a server.
