There are people that watch and judge everything. I went through a period where I was "eating clean" and if I attended a function with food that did not offer anything I wanted to eat, some people would make comments about the fact that I chose not to eat anything. "Oh you can afford to eat a few treats" was the most common. Not because I was thin, but I may have been thinner than some people attending(I have not been thin in my adult life) Short of telling the whole life story about working hard to lose about 40 lbs. and being a garbage eater most of my life and how I was working at changing that etc. I got eye rolls, and "oh it won't hurt you' etc.etc. I hated having to defend my choices so I can understand how anyone would feel when comments are made that imply a judgment of any kind. And I never criticized the foods offered. Or told anyone that they were making a mistake eating them. I usually just tried to politely refuse. No thanks, I just ate or some such thing if I could. (Hard to do while dh is making himself a plate.) Best to always keep your thoughts to yourself unless asked specifically, even when intentions are good. Believe me I have a mothering personality. I had a mom who passed away to early from heart disease and my dad had a stroke in his 60 's. I would like to think that I could help some one avoid that but I know how hard it is to change habits. I quit smoking completely only recently. But you know the saying " the road to he!! is paved with good intentions".
