Eric signed up for a nutrition class this semester with the hope that he would learn how to improve his diet and lose weight in the process.Eric has had a difficult time in the past understanding important aspects of energy balance,such as how many calories his diet should provide for weight loss and how to determine whether a food provides only a few or many calories.Eric weighs 175 pounds and is 5' 8".He enjoys playing sports such as basketball,softball,and soccer,but most days of the week he is too busy with classes and school work to engage in much physical activity.Generally,he sits most of the day and spends two to four hours per day walking and moving around.
Eric's diet consists mainly of processed foods and he tries to avoid eating at fast food restaurants.A typical day includes a donut or pastry and a coffee with cream and sugar for breakfast,a couple of sandwiches with bologna,salami,and cheese on white bread for lunch,and one or two frozen entrées from his freezer such as a fried chicken,Salisbury steak,or a cheese enchilada for dinner.Eric feels like the amount of food he eats is reasonable,and he cannot understand why he is not losing weight.
-What percentage of calories from the Salisbury steak dinner are coming from protein,fat,and carbohydrates,respectively?
A)12% protein,45% fat,43% carbohydrate
B)14% protein,54% fat,32% carbohydrate
C)14% protein,62% fat,24% carbohydrate
D)20% protein,49% fat,31% carbohydrate
E)23% protein,41% fat,36% carbohydrate

To determine the percentage of calories from each macronutrient, we need to know the total calories of the meal and the caloric content of each macronutrient. Assuming the serving size of Salisbury steak dinner is one, we can find the total calories by adding the calories from each macronutrient:

Protein: 17 g x 4 kcal/g = 68 kcal
Fat: 14 g x 9 kcal/g = 126 kcal
Carbohydrate: 11 g x 4 kcal/g = 44 kcal

Total calories = 68 + 126 + 44 = 238 kcal

Now we can calculate the percentage of calories from each macronutrient:

Protein: 68 kcal / 238 kcal x 100% = 28.6% or approximately 14%
Fat: 126 kcal / 238 kcal x 100% = 53% or approximately 62%
Carbohydrate: 44 kcal / 238 kcal x 100% = 18.5% or approximately 24%

Therefore, the answer is C, 14% protein, 62% fat, 24% carbohydrate.
