Hi Samantha,
I don't think Cat's comment was in any way intended to offend & seems harmless enough to me.
I was obese (now just overweight

) because - like others - I ate the equivalent of eating McDonalds three times a day. So I quite rightly looked like I ate McDonald's 3 times a day - cos in effect I did!
The film is about Americans - and it states that the USA has the highest percentage of obese / overweight people - so it was fair to say really.
Everyone on here is here for the same reason - we all want to lose weight and we all need each others support.
Cat is one of the most supportive people I have met on here - you only have to look at her mountain of other posts
Good luck with your weight losses
Kel
