Hi,
My family have noticed and have mentioned to me that I am looking better, and probably because they are not afraid to say anything to me, however, I have not told my friends that I am on a diet and they have not said anything, but the other day I decided to tell a couple of my friends because they were sitting there looking at me and wondering why I was not eating lunch with them and they said that they had noticed but were not sure weather to say anything, but they had been talking about it and they thought that I was getting thinner. So maybe this is the case with your friends too, they might be noticing, but not sure if they should say anything just yet. Wait you will get to a stage where there will be no way they can miss it and there will be no way they will not be able to say something about it.
My little niece who is only 7, said to here mum the other day, Aunty Sal looks pretty today. She thought it was just the clothes and my new earrings. But it made me feel very good. And her mum who is my best friend came up to me and told me what she said. That gave me such a good feeling.
So don't get disheartened, they maybe noticing, just not saying anything....yet
