The Protein Calculator estimates daily protein grams from body weight, activity level, and a maintenance, muscle-gain, or fat-loss goal. Weight in pounds is converted to kilograms before the range is applied.
The module multiplies body weight by an activity- and goal-specific range from 0.8 to 2.4 grams per kilogram, then reports minimum, maximum, and midpoint values.
Example
For a 70 kg person with moderate activity and a maintenance goal, the modeled range is 70 x 1.2 to 70 x 1.6, or 84 to 112 grams per day, with an optimal midpoint of 98 grams.
Questions
Does more protein always improve results?
No. Protein needs depend on total diet, training, health, age, and goals. More is not automatically better.
Does the calculator account for kidney disease or pregnancy?
No. Seek individualized guidance for medical conditions, pregnancy, or clinical nutrition needs.
Why does fat loss use a higher range?
The module intentionally uses a higher multiplier for its fat-loss goal assumption; it is not an individualized prescription.
