Keto Calculator: Calculate Your Optimal Macros for the Ketogenic Diet

A keto calculator is one of the first essential tools for accurately determining your daily calorie needs and nutrient targets on the ketogenic (keto) diet.

A keto calculator helps you follow the primary rule of the ketogenic (keto) diet: maintain the following proportions—70% of your calories from fat, 25% from protein, and 5% (but no more than 20 grams) from carbohydrates. This ratio helps your body switch to using fat for energy and prevents the initiation of gluconeogenesis (the production of glucose from protein).
