RDA Baseline (0.8 g/kg) vs ISSN Sports Protein Multipliers
Daily protein targets multiply body weight (or lean mass) by evidence-based activity factors: Grams/Day = Weight_kg × Factor. While 0.8 g/kg prevents deficiency in sedentary adults, the International Society of Sports Nutrition (ISSN) recommends 1.4–2.0 g/kg for strength training and 1.8–2.4 g/kg during fat-loss deficits. At 72 kg and 1.8 g/kg, 130 g/day divides into 4 meals of ~32.5 g.
Because our Protein Calculator applies these rules automatically, you avoid manual rounding mistakes. Furthermore, users looking for weight loss protein or vegetarian protein needs workflows can test multiple scenarios side by side before finalizing their work.

Important Scope, Privacy & Accuracy Notes
Calculated gram ranges reflect sports-nutrition and dietary reference guidelines for healthy adults rather than medical nutrition therapy. However, chronic kidney disease, liver disorders, or metabolic conditions often require clinician-supervised protein limits. Always consult a registered dietitian or physician before adopting high-protein regimens above 2.0 g per kilogram.
