Keto Macro Calculator
The classic ketogenic split is roughly 70% fat, 25% protein and 5% carbohydrate. Enter your daily calorie target and this calculator converts those percentages into grams of fat, protein and carbs — plus net carbs after subtracting the fiber you enter.
How to use
- Enter your daily calorie target.
- Optionally enter your fiber grams to see net carbs.
- Your fat, protein and carb grams appear instantly.
Note
Grams use 9 kcal per gram of fat and 4 kcal per gram of protein and carbohydrate. Net carbs = total carbs minus fiber. Very low carbohydrate diets are not suitable for everyone and can interact with medicines — medical guidance matters. Estimate only — not medical advice.
