The Twilight actress, who announced in May that she is expecting her second child with husband Seth Gabel, revealed that she did not want to gain as much weight this time around.
"My first pregnancy I gained 75 pounds. I had every intention... I told myself, 'I am going to be so fit this pregnancy'," Howard told People.
However, the 30-year-old went on to admit that she has put on the same amount of weight over the course of her second pregnancy.
"But I have pound for pound been the same weight at every single milestone! I'm German - my body wants to carry like a tank," Howard concluded. "It is what it is."
She recently confessed her fear that she will suffer post-natal depression again when she gives birth later this year.
The actress suffered from very intense morning sickness at the start of her second pregnancy.
