I bet we can all agree that women are more conscious of their weights rather than men. But there may be great cause for this concern since a 10-year longitudinal study showed that weight gain in women appear more often when they get married and when they have their first child.

But surprisingly, the study also said that “there was no effect on the rate of weight gain of having a second baby.” What’s even more interesting is that the results also showed that women gain weight whether they are single or not.

It said that women without a husband and without a baby gain an average of about 11 pounds per year. On the other hand, women with a partner but have no baby gained 15 pounds while those with a partner and a baby can gain as much as 20 pounds.

The reason, unfortunately, remain vague. Although one doctor proposes that single women gain less because they still want to attract males and that they don’t necessarily eat three meals a day. Also, the expert said that single women have more time to exercise than married women with children.
