Answer:
The sugars obtained by digestion of carbohydrates are slowly burnt to release energy. Some of the energy released is utilised by the body to generate heat and keep the body warm. During winter when the temperature outside is cold. Therefore the body needs to bum more sugar to generate more heat to keep the body warm. Whereas in summer less heat is required so less sugar is burnt to produce heat.

Since more sugar is required in winter to keep the body warm than in summer, we feel hungrier in winter than we do in summer.
