Weight is a weighty issue so unless someone has the inside scoop on why someone is gaining or losing weight and have been invited to comment on it, it is best to keep your mouth shut. It is not all about eating too much or eating too little. Sometimes, there is medication and/or illnesses and life issues causing problems of weight gains and losses in people. There are no perfect people! We all have flaws that become magnified when we insist on finding flaws in others.
