Calculate the recommended amount of protein per day for an athlete who weighs 210 pounds and the is l.5gm/kg.

Calculate the calories, from protein only in the following meal:

3 oz fish (21 grams)

1 medium baked potato (4 grams)

1 cup green beans (4 grams)

1 cup skim milk (8 grams)

Answer 1

recommended amount of Protein Per day, for a college student

• weight of student = 180 pound = 81.6kg
• RDA for protein is 0.8gm/kg
• so protein needed is 65.28 gm
• calorie obtained from 65.28gm of protein= 261.12 cal

recommended amount of Protein Per day, for a athelete

• weight of student = 210 pound = 95.2 kg
• RDA for protein is 1.5gm/kg
• so protein needed is 142.9 gm
• calorie obtained from 142.9gm of protein= 571.6 cal [ 1gm protein give 4 cal of energy]

calorie from protein

3 oz fish (21 grams)

• 3oz fish have 21gm protein
• [1gm protein give 4cal of energy]
• so, from 21 gm protein 21*4 =84 cal

1 medium baked potato (4 grams)

• 1 medium potato have 4gm of protein
• 1gm protein give 4cal of energy
• 4gm give 16 cal of energy

1 cup green beans (4 grams)

• 1 cup green beans have 4gm of protein
• 1 gm protein have 4 cal of energy
• so, 4gm protein have 16cal of energy

1 cup skim milk (8 grams)

• 1 cup skim milk have 8gm protein
• 1 gm protein give 4 cal
• 8gm protein give 64cal
