It depends entirely on u Aisha, and how u let people affect u. I was speaking about the same culture (desi) that u speak of. People will talk even if u're a size zero..and even if u're a size 20. Some men like "fuller" girls.. while some prefer really thin girls.
If a guy rejects u because of u're weight, he isn't even worth it! If u're on the heavy side, lose weight for urself and u're health..not because u gave-in to society's pressures and needed to attract rishta's.
