A woman has been left fuming after her sister, a personal trainer, barred her from a family barbecue because of her weight.

The woman, who is a size 16, took to the online forum mumsnet to vent her frustration over the situation.

Going by the username Fireplace1, she explained her sister set up a group chat with family members about a big barbecue she was hosting and wanted to know a date when everyone was free before setting a day.

In the post that was captioned "On a scale of 1-10 how mad should I be about this", the woman said even though there were a number of dates everyone could do, her sister chose the one day she couldn't do.

"I pointed out there were a lot of dates we could all do and she came back and said she wasn't sure I'd feel comfortable at the event as she was also inviting a lot of her clients, I phoned her to ask what this was supposed to mean.

"(My) sister is a personal trainer, I am overweight (size 16). Cut a long story short she started by saying everyone going was really slim and cared about their weight (my anger rose to about 5/10 here), then she proceeded to suggest it looked bad on her as a personal trainer if she had a 'fat' sister (anger soared to 10/10 at this point!) …"

The woman said she hung up the phone on her sister, which she had never done before.

"I am fuming!!!! What do I say to her?" she asked.

Fellow mumsnet users were quick to reply in supporting the clearly upset woman.

"I can't actually articulate a response at this point as I am: O. I get why you are at a 10 though," one person said.

"Oh my god, that's horrendous. In your position I would be writing on group chat that I/you feel very hurt that not only has she deliberately excluded you from an event (i.e. basically uninvited you) but that her reason for doing so is that you are not a size 8, gym-fanatic."

"Alternatively invite all of the family BUT her to some other event!" another advised.

A third disagreed, saying that she should say nothing to her sister.

"She needs to apologise. Vile attitude. Hopefully one of your family will deal with her nastiness."

Others described her sister as being "horrible" and "rude".
