I'm currently sat at my desk and keyboard with gritted teeth and smoke emanating from the top of my head
I can sit here and tell a hundred and one stories about gluttonous induced overweight problems, where the finger of blame is pointed at everyone BUT the person over eating. These people are the ones who make the "normal" weight people feel they have a right to assume that everyone who is over weight over eats, and makes them feel they have the right to poke fun!
I have a friend who was very overweight and large in size. BUT she ate so well - no unnecessary fatty foods, snacking etc. She exercises. Takes necessary vitamins etc etc. But every time she went to the GP and "specialists" explaining that she was concerned that there could be some wrong, they just turned around and told her to address her diet.
To cut a very long story short, through pure chance and an unrelated health matter it became clear that she had a grossly under-active thyroid. For years this went undiagnosed. Now she has started to shed the weight and is looking and feeling much healthier... and happier.
I unfortunately have the exact opposite problem to this. I'm grossly and worryingly underweight

Especially since my last flare
And KarolH, I've been to the US and know exactly what you are talking about.. especially the "portion sizes". And, in relation to what I said about my weight, when in the US people were staring and poking fun at me and my [lack of] size. I was made to feel like a freak there... especially in Orlando.
But to all, I think that we should ignore the ignorance or lack of knowledge of these people and try our best to make ourselves feel better and improve our health.
