How do I know how much more food should eat during my pregnancy?

Perhaps the thought of carrying someone inside you , gives you the opportunity eating double, So an extra pizza , a big burger or a big chocolate daily is a logic tactic for some pregnants..Bad for you, a pregnant just need a little more extra food and only during second and third semester. 

Tip : You do not need so much  extra food as many pregnants believe. An extra salad or a toast or a small portion of meat is adequate at second or third semester.
