Why do most Christians and Catholics ignore the sin of gluttony yet raise hell for people that lust, etc?

I am not judgmental but if you won't shut up about people having premartial sex, lusting, doing this and that or whatever why do you ignore Gluttony? The most judgmental Christians and Catholics are in the south and midwest yet many of them are over eating and fat. Pointing out other sins but their own.
