Answer:

465 Kilo calories

Explanation:

Convert each nutrient from percentage to grams

Total weight of the meal = 186 grams

Fat (10%) = 18.6 grams, Carbohydrate (30%) = 55.8 grams, Protein (10%) = 18.6 grams, Water (50%) = 93 grams

To calculate the energy available per nutrient, we will multiply the number of grams of carbohydrate, protein, fat by 4,4 and 9 respectively;

18.6 grams of fat x 9 Kcal = 167.4 Kcal

55.8 grams of carbohydrate x 4 Kcal = 223.3 Kcal

18.6 grams of carbohydrate x 4 Kcal = 74.4 Kcal

Water is calorie-free

Therefore, the total number of kilo calories is

167.4 + 223.3 + 74.4 = 465 Kcal

Answer: 465 kilocalories

Explanation:

The total weight is given as 186g

10% fat= 10/100*186g

= 18.6g of fat

30%Carbohydrate= 30/100*186g

=55.8g of carb

10%Protein= 10/100*186g

=18.6g of protein

50%Water= 50/100*186g

=93g of water

Water contains 0 calories. Therefore 93g * 0kcal/g =O kcal

Fat has 9kcal/g

Therefore, 18.6g*9kcal/g

= 167.4kcal

Carbohydrates have 4kcal/g. Therefore, 55.8g*4kcal/g

= 223.2kcal

Protein has 4kcal/g. Therefore, 18.6g* 4kcal/g

=74.4kcal

Sum of the kilocalories content of the food is

=167.4kcal + 223.2kcal + 74.4kcal + 0kcal

= 465kcal.
