Final answer:
A 120-pound woman (54.5 kg) aiming to gain significant muscle mass as a bodybuilder should consume between 1.2 and 2.2 grams of protein per kilogram of body weight daily, which equates to 65.4 to 119.9 grams of protein a day. It is crucial to seek professional advice to determine the precise needs and develop a tailored nutrition plan.
Step-by-step explanation:
The daily protein intake for someone who is looking to gain a significant amount of muscle mass, such as a 120-pound woman aiming to become a bodybuilder, can vary broadly based on certain factors, including activity level, body composition goals, and individual metabolism. While the general daily dietary recommendations suggest a balanced diet including 70 grams of proteins, bodybuilders often consume a much higher level of protein to support muscle repair and growth.
It's commonly recommended for bodybuilders to consume between 1.2 and 2.2 grams of protein per kilogram of body weight. For a 120-pound woman, which is approximately 54.5 kilograms, her daily intake should be between 65.4 grams (1.2 x 54.5) and 119.9 grams (2.2 x 54.5) of protein. However, it's essential to consult with a healthcare professional or a certified nutritionist to create a tailored nutrition plan, especially when looking to make significant changes to body composition.
