Yesterday my wife and I visited friends. She and they were talking in Korean when she suddenly turned to me and asked “Have you put on or lost weight?” It’s a perfectly formed question, but I didn’t like the implication, especially as I have, in fact, lost one or two kilograms recently.
PS Last month I had to complete a comprehensive medical survey, and one question was ‘Has your weight altered substantially in the last 12 months?’
Never Pure and Rarely Simple 
Unless your weight has stayed exactly the same all your life, you would be perfectly correct in just answering “Yes.”
