A keto calculator uses your age, weight, height, activity level and goal to estimate daily calorie needs. It then splits those calories into the high-fat, moderate-protein, low-carb ratio used on a ketogenic diet.

Limitations of keto calculator

• Estimates are approximate, not exact medical advice
• Doesn’t account for individual metabolic differences
• Not suitable without checking for existing health conditions
• Results may need adjusting as your body adapts
