Question
John is a 24 year old male who just graduated from college and landed a great job. John is 6’0”. Before college, John weighed 180 pounds without even trying to maintain a particular weight. However, with two jobs to make it through school, John put on about 25 pounds by eating convenience foods at odd hours, often on his way to one of his jobs or to class. John realized that his new weight of 205 pounds was not what he wanted to keep. Now that John has a steady income and only one schedule to worry about, he is ready to join a gym. At the gym, John made a friend (Fred) in the weight room who is giving him advice to help him get in shape. Fred has told John that he needs to eat at least 200 grams of protein every day.

Explanation / Answer
b. About 64 to 128 grams of protein per day
John's BMI is, 27.8, which is under "heavyweight." The protein intake should range between 25% to 30% of the total calorie intake. The healthy levels of total protein recommendations for John range between 64-128 grams.
Body mass index (BMI) provides an approximate estimated value of requiring body weight for a particular height (weight-for-height). BMI can be calculated by the following formula.
BMI = Body weight (in kilograms)/ Height2 (in meters), OR
BMI = Weight (pounds) × 703/ Height2 (inches).
The BMI value of a “healthy weight for height” ranges in between 18.5 to 24.9. BMI of more than 25 and lower than 18.5 increases the health risks.
The BMI value of 25-30 indicates overweight. This is also equal to, having 10% to 20% of the excess body weight than the required body weight.
