Question

Yesterday nadia consumed 250 grams of carbohydrate, 75 grams of protein, and 60 grams of fat. 57) what percentage of calories of her day's intake came from fat?

Answer 1

Number of calories gained when eating different types of food differs. Some food types are more fattening relative to other types.
the number of calories consumed when eating carbohydrates -
         - 4 calories/ gram * 250 g  = 1000 calories
calories gained eating proteins - 
         - 4 calories/gram * 75 g  = 300 calories 
calories gained eating fats  
          - 9 calories/ gram * 60 g = 540 calories
total amount of calories consumed = 1000 + 300 + 540 = 1840 calories

percentage of calories coming from fats = 540/1840 *100% = 29.3 %
