Protein Calculator
Estimate daily protein intake by weight, activity and goal, then split the target into per-meal ranges you can compare with real food logs.

Method
How this protein calculator works
The calculator converts body weight to kilograms, applies a goal-based protein range, then adjusts modestly for activity. It also divides the result across meals so the target is easier to act on.
Convert weight to kilograms when needed.
Use a lower adult baseline for general health and higher ranges for weight loss or muscle goals.
Add a small activity adjustment for regular training.
Divide the daily range by meal count and show practical meal examples.
Use the result
Protein goals work better beside real meals
The calculator gives a daily range. Eatibo helps users compare that target with breakfast, snacks, packaged foods and restaurant meals instead of guessing at the end of the day.
- Scan meals to estimate protein without manual lookup
- See whether protein is spread across meals
- Keep protein goals connected to calories, carbs and fat
Limits
Helpful estimate, clear boundary.
This is a general adult estimate, not medical nutrition therapy.
Follow clinician guidance for kidney disease, dialysis, liver disease, pregnancy, eating disorder recovery or prescribed protein limits.
High-protein targets do not guarantee muscle gain. Training, total calories, sleep and consistency still matter.
FAQ
Quick answers about protein calculator.
Is this a protein calculator or a protein intake calculator?
Both. It estimates a daily protein intake range from body weight, activity and goal, then splits that range into practical per-meal targets.
How much protein do I need per day?
Protein needs depend on body weight, activity, goal and health status. This calculator gives a daily gram range and a per-meal target for general planning.
How do I calculate protein intake by weight?
A common approach is to convert body weight to kilograms and multiply by a protein range. Lower ranges fit general health; higher ranges are often used for weight loss or muscle-focused training.
Is a protein calculator useful for weight loss?
It can be useful because protein can support satiety and lean mass during a calorie deficit. The result is still only a target; actual meals need to be logged consistently.
How should I split protein across meals?
Many people find protein easier to hit when it is spread across 3-5 meals or snacks. The calculator divides your range by meal count to make that visible.
Can I use this protein calculator for kidney disease?
No. Kidney disease, dialysis, liver disease or clinician-directed protein limits require individualized guidance from a care team.
How does Eatibo help after I calculate protein?
Eatibo can scan meals and labels, estimate protein and show whether your day is on track without manual nutrition lookup.
