Why the girls becoming fate after marriage?

You are correct Some girls but not all become fat.Iam girl who is same as before my Marriage and i also have a kid. It all depends on food they take and atmosphere they live. And many girls wont Diet after marriage because they wont care about their health.They have to look after their Husband and their Kids.Some times they wont get time to eat properly at correct time.I think that may be the reason for becoming fat. Of course we dont worry for the thing whether any one is going to marry us or not if we wont be good looking and slim.

I think girls become more complacent after the marriage about their figure so they become fat.

it is because they become more happy and satisfied with their life after marriage. and they don't have to bother about their figure anymore.

I think that what you are talking about--girls feeling that, once they're married, they don't have to worry about their weight any more--is probably true. However, stress and depression also might factor in.

before marriage they have to secure ,, after marriage they have inner charm as they got whatevr they wished

gals become fat because of their happiness and satisfaction they get after their marriage. moreover there are some scientific reason too, where they undergo some hormonal changes too...
