Chubby does not equal unhealthy. It can be unhealthy, but so can being a normal weight or underweight. Being underweight can actually be more dangerous because once you hit a certain point, your body actually starts to shut down because it doesn't have the energy to keep running. But any doctor or nutritionist that's not a hack will not tell you that chubby is automatically unhealthy.
And me, I've got a fat ass, hasn't given me any problems in getting the attention of guys. Or girls, for that matter, either.
