Protein Calculator
Estimate a daily protein range from body weight, age, goal, protein source and meal frequency, with US and metric inputs.
Protein planning inputs
Estimate a daily protein range for healthy adults. Kidney disease, liver disease, gout, pregnancy, lactation, eating disorders and prescribed diets need professional guidance.
Daily protein intake estimate
Protein needs are often estimated from body weight and goal. The tool gives a lower range, practical target and upper planning range rather than one universal prescription.
Weight-based protein estimate for adults.
Protein by meals
Dividing protein across meals can make the target easier to follow. The result is a planning aid, not a requirement to hit the exact same grams at every meal.
