Question

• B. First fats, next carbohydrates and lastly proteins
• C. First carbohydrates, next proteins and lastly lipids
• D. First proteins, next lipids and lastly carbohydrates

Answer 1

The correct option is A First carbohydrates, next fats and lastly proteins

During prolonged fasting, the body undergoes several biochemical and hormonal changes to make up for the lack of food and hence energy so as to be able to continue the vital processes needed for existence. The glycogen and glucose stored in the body last for a short time. After these, the body moves onto the adipose tissues or the fat accumulated in the body so that the store of vital proteins in the body gets spared or is utilized at last.

So, the correct answer is 'First carbohydrates, next fats and lastly proteins'.
