The question asks: For a sedentary individual who weighs 180 lbs, how many grams of protein would they need to consume daily to avoid a protein deficiency? The provided answer is 65 grams, and there are no answer options to analyze.
First, convert the body weight to kilograms: 180 pounds divided by 2.205 gives approximately 81.6 kg.
Next, apply the standard recommended daily protein intake for a sedentary adult, which is about 0.8 grams of protein per kilogram of body weight. Multiplying 81.6 kg by 0.8 g/kg yields roughly 65.3 g of protein per day.
Rounding to the nearest whole gram, 65 g/day is a reasonable, conventional estimate for meeting daily protein needs in a sedentary individual of this weight.
Now, consider why other potential interpretations might be incorrect if we had alternative options:
- If someone used a much higher value, say 1.2–1.6 g/kg, that would be appropriate for athletes or people aiming to preserve muscle but not for a sedentary baseline; it would overestimate daily needs.
- If the calculation used pounds directly without converting to kilograms, you might end up with an incorrect result because the 0.8 g/kg guideline is defined per kilogram, not per pound.
- If a value was significantly lower, such as 30–40 g, that would understate the recommended intake and could lead to insufficient protein, especially over time.
- Some guidelines propose different ranges (e.g., 0.8–1.0 g/kg for various populations), but for a standard sedentary adult, 0.8 g/kg is a widely accepted baseline, making 65 g/day a defensible estimate for this scenario.
Overall, the 65 g/day figure aligns with the standard calculation using 0.8 g/kg for a sedentary adult weighing 81.6 kg (180 lb).
