How to use keto macro targets
Use calories, net carbs, and protein as fixed inputs, then let fat fill the remaining energy target.
Net carbs set the carb ceiling
A strict ketogenic plan often uses a low net-carb target. The calculator labels the carb range, but it cannot confirm whether you are in ketosis.
Protein is entered directly
Protein needs vary by body size, training, age, and medical context. Enter your chosen target, then review whether the remaining calories leave enough room for fat.
Fat fills the rest
After net-carb and protein calories are assigned, the remaining calories are converted to fat grams using 9 calories per gram.
Keto Macro FAQ
Common questions about net carbs, fat grams, and what this calculator can estimate.
Can this tell me whether I am in ketosis?
No. It calculates macro targets from your inputs. If you need confirmation, use an appropriate ketone test and interpret results with qualified health guidance.
Why is fat calculated after carbs and protein?
Net carbs and protein are usually the more constrained planning targets. Fat is then calculated from the calories that remain.
What if carbs and protein exceed my calorie target?
The calculator will show that no calories remain for fat. Increase calories, lower net carbs, lower protein, or revisit the targets before treating the plan as usable.
