why do we feel hungry at specific time
Answers
Answer:
Hunger is a way of letting us know that we need to have food. Hunger is a powerful human instinct which at times, when severe, compels us to extreme behavior like when we are extremely hungry our brain stops working. It’s our body’s response to having eaten less than enough or an indication to eat at a regular interval.
The brain reads the changes in the levels of nutrients and hormones in the body and makes us feel hungry. When hunger starts to contract the stomach, it is referred as hunger pangs. Hunger pangs normally don’t start until 6 to 7 hours after the last intake of food. Individual contractions are usually separated at first but are continuous after a certain period of time. The hungry feeling is also enhanced by low levels of sugar in the blood and those who are diabetics. Although according to researches, hunger never disappears. It’s contractions are most intense in young and healthy people who have high degrees of gastrointestinal tonus and periods between contractions increases with age but contractions tends to decrease during old-age.
