I think fat is a lazy term for a professional to be using especially when teaching a junior.
I think the OP made the situation on this thread more difficult for herself by including the ridiculous I once saw a fat HCP carrying fatty food with his family story. That automatically made her sound a bit of a judgemental twat.
I do understand some of the points being made. Yes of course we need to tackle the countries growing waistband and it needs to be tackled head on.
However, calling people fat isn't going to suddenly make someone go oh yes why didn't anyone say so before I can now magically lose weight.
Some people need to understand that the word fat can be extremely insulting not many people in the street shout out oh my god look at that obese cow, or jesus look at her she must have a massive bmi.
No they tend to shout out; 'fat bitch', 'fat cunt', 'oh my god look how fat she is', 'bloody hell shoot me if I ever get that fat', 'eurgh look at the state of that how can anyone get that fat it's disgusting' and my personal favourite whilst I was with my husband 'fucking hell look how fat she is, how could you ever want to fuck that fatty bitch, talk about roll her in the flour.'
So I agree fat itself is just a word just like cunt which some people use affectionatley or bitch that can be said with no offense being meant at all. However, in my opinion because a lot of people use fat purely to cause offense or hurt the medical profession should where possible refrain from using the term.
