One of the reasons why you may be feeling a little hungry is because the hormone leptin - which controls hunger - is a little off during pregnancy. Receptors in the brain work to suppress chemicals that suppress your hunger - thus causing you to become more hungry, to ensure that you will eat enough to get your baby more nutrients.
Hunger during pregnancy is common because the body needs extra calories for energy, says Nancy Rector-Finney, MD, with Methodist Children's hospital. In this video, she discusses the importance of extra calories while being cautious of overeating.
While you may fight many battles during pregnancy, there's one battle in particular, which takes place deep inside your brain, that has lifelong implications. In a nutshell, your body regulates the way you eat through the communication between two hunger-related hormones: leptin (the superhero) and ghrelin (the evil Twinkie-loving villain). If you can learn to increase leptin by eating good foods, you'll score a knockout victory in the battle between your tummy and your tongue.
