^^I'm not one of them to encourage a woman to lose weight. If they got fatter and they're happy about it. I do not mind and that's what love is about. It is not the men's job nor the woman's job to run each other's decisions on their image but an advice is always good if he/she is willing to take it.
showing at least some level of concern for the other half's health is an examination of love, doesn't it? if not, that's a sign of neglection or emotional abuse. historically, overweight and obese -- they're risk factors which could lead to heart disease and worse. the risk factors have been well documented.
personally i want my children -- even in their 30s and 40s -- still have their mommy enjoying their precious moments or hugging our grandchildren. i guess that's me.
