What the three assumptions mean
The adult RDA reference uses 0.8 g/kg. The current 2025–2030 U.S. Dietary Guidelines state a 1.2–1.6 g/kg target. The ISSN position stand describes 1.4–2.0 g/kg for most exercising adults. These broad references do not account for kidney disease, pregnancy, age-specific needs, medical diets, or an individualized training plan.
