"twice the protein! " have you seen this advertising slogan for greek yogurt and some nutritional sports products? do we really need that much protein in our diet? let’s take the guessing out of the equation and calculate protein requirements based on the current recommendations. part a - calculating protein requirements for a healthy adultwhat is the daily protein requirement for sarah, a 136-lb, moderately active 32-year-old woman? during calculations, use numbers rounded to the first decimal place. in your answer, round the number of grams to the nearest whole number.

A. 60 grams protein

B. 74 grams of protein

Explanation:

The amount of protein needed depends on weight and lifestyle. The daily minimum recommended by the National Institutes of Health is 0.36 grams per pound for a sedentary person. But the daily optimal intake for this same sedentary person is 0,8 grams of protein per kg of body weight. On the other hand hand, adults with a more active lifestyle need more protein in their body, the intake should be between 1,2 and 2,0 grams of protein per kg. For example, endurance runners need up to 1,4 and strength training athletes need up to 1.8 g of protein per kg.

The first step for calculating protein requirements is calculate the weight in kilograms, so we need to divide the weight in pounds by 2,2.

154lb/2,2= 70 kilograms

Then we have to multiply the weight in kg, times the number of protein needed per day, 0,8 for a sedentary healthy adult.

70kg x 0,8= 56 grams

Part A:

165-pound (lb) male who is healthy but sedentary

165 lb/2.2 = 75 kg

75 kg x 0,8 = 60 grams protein per day

Part B. Sarah is moderately active so we need to use a number between 1,2 and 2, since shes active but not very active we can use the 1,2.

136-lb/2,2= 62 kg

62 kg x 1,2 = 74 grams of protein
