Think back to a time when you bumped into someone you haven't seen for a while and you were taken back by how different they looked. After a few moments, you realize that what was different was their weight. They looked great and the weight loss was clearly evident. What do you say to them? Responding to someone's weight, whether it is a weight loss or a weight gain should be handled thoughtfully. If you jump right out there and say "Wow, you've lost so much weight", they might feel offended as it implies that they were heavier the last time you saw them. Here are some things you can say to someone in that situation: "you look great, what's your secret? You look so amazing or I love what you are wearing, you look great in it. The key is no matter what you say to someone about their appearance, try to consider how what you say might make them feel.
