Well, it depends on the woman and what she wants or doesn't want. Unless they intentionally want to gain it often seems to take getting knocked up, and/or finding some abusive asshole (in childhood or adulthood) who abuses and demeans them until they start eating their feelings of inadequacy. Sometimes it's an office job. Sometimes it's a drinking problem (see above). Sometimes it's an illness or hormonal imbalance (Google PCOS) Not all women get fat.
