Second and Third Trimester. It is normal for pregnant women in their second or third trimester to be hungrier because their baby needs more fuel to develop at this stage. You will need an average of 300 extra calories a day to gain weight at a healthy pace while supplying enough energy to your growing baby. You can calculate your daily calorie need for these trimesters simply by adding an extra 200 calories a day compared to what you were eating during the first trimester.
usurpation. 1  an act of usurping; wrongful or illegal encroachment, infringement, or seizure. 2  illegal seizure and occupation of a throne.
