Calculate the protein needs of a healthy 140-lb. woman.?

To calculate the protein needs of a healthy 140-lb woman, a common recommendation is to consume 0.8 grams of protein per kilogram of body weight. First, convert 140 pounds to kilograms by dividing by 2.2, which gives approximately 63.6 kg. Multiplying 63.6 kg by 0.8 g/kg results in about 51 grams of protein per day. Depending on activity level, some may benefit from higher protein intake, but 51 grams is a good baseline for general health.
