I don't necessarily think that it is bad for a parent to complain about themselves being fat. As long as they are properly addressing their health problems with a proper diet and exercise plan, the kid can learn. If the parent is doing nothing about their weight, but complaining or losing a few pounds and giving up they can be causing a child severe damage. This could develop into an eating disorder because fat parents keep fat foods around so a child may feel helpless with their choices and become anorexic or bulimic. Even if an eating disorder is not caused the parents are setting a horrible example for their child. Losing weight is attainable for everyone. Complaining about losing weight and not losing the weight is having a "quitter attitude". Losing weight is hard and a parent accomplishing losing weight can be very inspirational for a child. A parent failing time and time again lets a kid know that if things get too hard you can quit.
