Final answer:
Approximately 11.1 grams of protein provide the same fuel value as 25 grams of fat.
Step-by-step explanation:
When we compare the fuel value of proteins to fats, we must take into account the different calorie content per gram of each macronutrient. One gram of fat contains 9 calories, whereas one gram of protein contains only 4 calories. To calculate the grams of protein that would provide the same fuel value as 25 grams of fat, you multiply 25 grams by 9 calories per gram to get a total of 225 calories from fat. To find the equivalent amount in protein, divide 225 by 4 calories per gram of protein, resulting in 56.25 grams of protein.
Fatty foods are calorie-dense, meaning they have more calories per unit mass than carbohydrates or proteins. One gram of fat has nine Calories while one gram of protein has four Calories. Therefore, to find out how many grams of protein provide the same fuel value as 25 g of fat, we can set up a proportion:
25 g of fat / 9 Calories = x g of protein / 4 Calories
To solve for x, we can cross multiply and divide:
25 g of fat x 4 Calories = 9 Calories x g of protein
x = (25 x 4) / 9 = 100 / 9 ≈ 11.1 g of protein
So, approximately 11.1 grams of protein provide the same fuel value as 25 grams of fat.
