Hello!

The answer is b. inadequate calorie intake and inadequate carbohydrate storage

Explanation:

Our body requires energy to carry out daily activities and body functions. This energy is available to the body in three forms:

carbohydrates fats proteins

Carbohydrates are the first and most readily available source of energy as starch and complex carbohydrates and sugars are immediately broken down into glucose which is available for body cells. Excess glucose is also stored as glycogen in the muscles. During exercise, carbohydrates, particularly, glucose are the first sources of energy for the body.

Fats provide the highest energy of all three (9 kilocalories compared to 4 of protein and carbohydrates). Fats are stored in the body in the form of adipose tissues or body fat. Any excess energy is readily stored by the body in the form of fats.

As proteins are not stored by the body, they are the last to be broken down during strenuous or prolonged exercise. Protein, particularly the skeletal muscle is the last to be used for energy in case of low calorie intake and inadequate carbohydrate stores.
