Question

After we work hard or perform physical activity, we feel hungry. Explain why​

Answer 1

Answer:

After a physical activity, we take deep breathes and inhale more oxygen. As a result, more oxygen is supplied to our cells and the process of breakdown of food speeds up. Due to this, more energy is released and we tend to feel hungry.

Answer 2

Answer :-

During physical activities such as walking , fast running , exercising etc. we need extra energy and so we breathe faster . This supplies more oxygen to our cells and hence speeds up the process of breakdown of food and more energy is released . As during this process more food is burnt or oxidised , so we feel hungry after a heavy physical activity .
