Almost exactly the amount of protein needed About twice as much protein as needed About three times as much protein as needed

Answer 1

1.

The estimated amount of nutrient or calories per day considered essential to maintain good health is called Recommended Dietary Allowance (RDA).

Manuel is college senior , so he will be 17 or 18 years of age.

His weight= 175 pounds

His height= 6 feet 2 inches

to calculate RDA of protein = 0.8× weight in kilograms.

( the need for a normal healthy human is 0.8 grams of protein per kilogram of body weight).

So to calculate the RDA of protein, when the weight is in pounds, the constant has to be divided by 2.2

ie 0.8/2.2= 0.36. This is because weight in kilogram= weight in pounds/ 2.2

to easily calculate RDA of protein =0.36×Weight in pounds

   = 0.36× 175 = 63 grams

Manual's RDA for proteins is 63 grams. In the first question the answer option is the third.

2. Manual is consuming twice as much Protein needed normally for his body.

So the second option is the correct answer.
