✅ What Is a Keto Calculator?

A Keto Calculator is a specialized tool designed to help individuals following the ketogenic diet calculate their optimal daily intake of calories and macronutrients—fat, protein, and carbs.

Unlike generic calorie calculators, a keto calculator tailors your diet to fit the macronutrient ratios essential for entering and staying in ketosis—a metabolic state where your body burns fat for fuel instead of carbohydrates.

Our calculator provides you with:

  • Calories per Day
  • Fat Intake (in grams)
  • Protein Intake (in grams)
  • Net Carbohydrates (fixed at 25g for ketosis)
