There was a similar thread on here yesterday and i didnt reply to it as i was on my phone and it takes ages to type. I will share this with you.
Im 26 years old. Have yo yo dieted from the age of 15. The only area i put weight on is my face and stomach. Over the years i ve been asked ALOT if im pregnant.
There was a time around 5 years ago when 3 women at work was overheard saying awful things about my weight ( i was a size 14) and how i looked 6 months pregnant etc.
A colleague overheard these women and repeated to me what was said, i cant remember the exact words but it was awful, and the bloke who repeated it to me said it was awful to listen to but i had a right to know.
I confronted the main one who said it and a row erupted and we were dragged into the office by our manager.
The manager was appalled with what was said, and the woman was told if anything like that was said again, then she would go down the disciplinary route.
Those comments from her stay with me even now.
A year after the incident, i was working in another work place. When i had been working there around 8 months, a very skinny, health conscious size 6 member of staff took me to one side and started to advise me on healthy eating! She also mentioned that i was spoiling myself with my weight and if i lost the weight i would easily get myself a boyfriend! 
I was stood there open mouthed for half an hour whilst she made me feel like shit. She also mentioned that when i first started the company, she was convinced i was pregnant!
I ve been a size 10.12,14,16 and now im a 18, but currently doing something about it.
Honestly op, people are fucking idiots and don't realise what they are saying.
You have my sympathy.
