Question

Margaret is a marathon runner, and she knows that with her daily training schedule she needs to eat more protein than an average woman her age. being a lifelong runner, she is also cognizant about keeping her weight in check to avoid excessive strain on her knees and feet. since she also knows that excess proteins won’t increase her performance, but will be metabolized into fat and stored in her body, she wants to eat just the right amount of protein. margaret’s current weight is 115 lb. her schedule is very intense. she works as a physical therapist, runs at least 9 to 12 miles every day, and does moderate weight training for a half hour every day as well. she runs competition marathons once every 2 months. she is not a strength athlete. margaret loves lean meat like fish and chicken, and eats it at least five times per week. as a non-vegetarian endurance athlete, margaret needs 1.2-1.4 grams of protein/kg body weight daily. Calculate how many grams of protein margaret should consume on a daily basis.

Answer 1

First, we need to convert Margaret's weight from pounds to kilograms:

115 lb ÷ 2.205 = 52.16 kg

Next, we can calculate the range of protein intake she needs:

1.2-1.4 grams of protein/kg body weight daily

So for Margaret:

1.2 g/kg x 52.16 kg = 62.59 g of protein per day (minimum)

1.4 g/kg x 52.16 kg = 72.82 g of protein per day (maximum)

Therefore, Margaret should consume between 62.59 g and 72.82 g of protein per day. It's important for her to stay within this range to support her intense training schedule, but avoid excess protein intake that can lead to weight gain
