I have two friends who have been losing weight lately, say about 1-2 stone each. Both would be classed as overweight/plus size at their start point, I think, although I don't know their weight or dress size. I know about their weight loss from them mentioning it and when I look for it I can see it, although I must admit I hadn't noticed it off my own back.
I genuinely don't know whether this is kind of self-absorbed of me and I should be paying more attention, or whether it's OK that it just doesn't matter to me. To me they're my friends, they would still be my friends however their weight fluctuated, and their weight just isn't really on my radar. As my friends I wish them success in their weight loss goals and would be sad at their distress if they were gaining and unhappy about it, but in itself it doesn't matter to me. If they said "I've lost a stone doing Slimming World", I'd say "Awesome, well done you, how are you finding it?" But I wouldn't spontaneously say "You've lost weight", partly because it feels like such a no-win situation; what if it's actually "I'm too depressed to eat" not "my diet is going really well"?
And, no, I don't tend to talk about diets and weight with my friends. I don't diet, I hate being made part of other people's "ooh, should I eat it, I'm being so naughty, what if we split it" neuroses about food (hello DM), so it doesn't generally come up.
So. AIBU to think that my friends' weight is not any of my business?
