For athletes aiming for weight loss, what is the recommended daily protein intake to preserve muscle mass?

Question

When considering protein needs for athletes who want to lose weight while preserving muscle mass, it helps to compare the ranges and the underlying goals.
Option 1: '1.3 to 1.7 g/kg body weight' aligns with evidence-based guidance that higher protein intakes help maintain lean mass during caloric restriction and can support satiety and metabolic efficiency in athletes.
Option 2: '2.8 to 3.5 g/kg body weight' is far above typical athletic recommendations for protein, and while some extreme programs might push high intakes, this level is generally unnecessary for most athletes and could displace other important macronutrients; it also carries a risk of unnecessary calorie excess.
Option 3: '0.8 to 1.2 g/kg body weight' reflects the general Recommended Dietary Allowance for protein for average adults, but it is often deemed insufficient for athletes, especially during weight loss, when additional protein is used to preserve muscle.
Option 4: '1.8 to 2.7 g/kg body weight' falls into a higher range that some athletes use, particularly in very intensive programs or specific sports, but it goes beyond what is commonly recommended for weight loss phases and may not provide extra benefits proportional to the added intake for most athletes.
In summary, the middle-to-upper range identified in Option 1 specifically targets preserving muscle mass during energy-restricted periods, whereas the other options either exceed typical needs without clear advantage (Option 2 and Option 4) or stay at a level generally considered too low for athletes during weight loss (Option 3).
