How many grams of protein does the average person require per kilogram of body weight each day?

  1. 0.5 to 0.6 grams

  2. 0.7 to 0.8 grams

  3. 0.8 to 1 gram

  4. 1 to 1.2 grams

The correct answer is: 0.8 to 1 gram

The average person requires approximately 0.8 to 1 gram of protein per kilogram of body weight each day. This recommendation is grounded in the needs of the average adult to maintain basic physiological functions, support metabolism, and ensure the repair and maintenance of tissues. The 0.8-gram figure represents the minimum daily requirement for sedentary adults, while the upper end of 1 gram provides a margin that can support those with slightly higher levels of activity or those engaged in fitness and resistance training. This range recognizes that protein is crucial for numerous bodily functions, including muscle repair, hormone production, and immune function. It's important to note that as activity levels increase, or if the individual is involved in specific training programs, protein requirements may increase, which could push recommendations closer to the higher end of the range. As for the other options, they either fall below the established recommendations for the average individual or are geared toward specific populations (such as athletes) who may require more protein for optimal performance and recovery.
