Question

1 gram Fats provides energy -

• A. 4 Kcal/g
• B. 12 Kcal/g
• C. 5 Kcal/g
• D. 9 Kcal/g

Hint:

Carbohydrate 4, protein 4, fat 9 Kcal per gram.

Answer 1

The Correct Option is D

Step 1: Use the energy ratio:
Fat gives about 2.25 times the energy of the same weight of carbohydrate. This is a well known rule in nutrition.

Step 2: Do the calculation:
Carbohydrate gives 4 Kcal per gram. So fat gives about $4 \times 2.25 = 9$ Kcal per gram.

Step 3: Match with the options:
Only option 4 shows 9 Kcal per gram. The 4 Kcal option is the carbohydrate and protein value, and 12 and 5 are not standard values.

Final Answer:
Fat gives 9 Kcal per gram. \[\boxed{9\ \text{Kcal/g}}\]
