Final answer:
A fast food cheeseburger containing 19g of fat, 20g of carbohydrate, and 28g of protein provides a total of 363 kcal. The fat content contributes significantly to the caloric density of the meal, which can lead to health risks if consumed regularly.
Step-by-step explanation:
The question asks how many kilocalories (kcal) of energy a cheeseburger from a fast food restaurant contains, given it has 19 g of fat, 20 g of carbohydrate, and 28 g of protein. To calculate the total energy content, we use the accepted caloric values for foods: 4.0 kcal/g for carbohydrate and protein, and 9 kcal/g for fat. The total energy is calculated as follows: (20 g carbohydrate × 4 kcal/g) + (28 g protein × 4 kcal/g) + (19 g fat × 9 kcal/g), which equals 80 kcal from carbohydrates, 112 kcal from protein, and 171 kcal from fat.
The sum gives a total of 363 kcal for the cheeseburger.
Fast food meals like this are often high in calories due in part to their high fat content, which is more calorically dense than carbohydrates or proteins. For someone like Abdul, regularly consuming these high-calorie meals can lead to an energy imbalance, weight gain, and an increased risk of various diseases related to obesity.
