What your result means
This calculator estimates a practical daily protein target based on your body weight and the goal you choose.
Protein targets are more useful when they are linked to body weight rather than using one fixed grams-per-day number for everyone.
Why your result is shown as a range
There is not one perfect protein number for every person. A practical range gives you room to stay consistent without chasing an exact figure.
The suggested target gives you a simple midpoint to start from, and the meal split helps turn the number into something easier to use.
Worked example
Example inputs
- Weight: 70 kg
- Goal: Build muscle
Example outputs
- Suggested protein target: 112 g/day
- Practical range: 112 to 140 g/day
- Across 3 meals: 37 g/meal
This example shows how the calculator uses body weight and goal to create a suggested protein target and a practical working range.
Common mistakes
- Thinking more protein is always better.
- Treating one number as exact instead of using a practical range.
- Assuming supplements are required to hit your target.
