Well, I'm in a state of singledom right now (Got charmingly dumped last year...) and I live alone so the only person who is responsible is me!
But it does mean I have to dodge the social minefield of eating out and drinking. Most of my friends are supportive but there's some who I just haven't told because it would just be too much hassle.
My biggest obstacle is actually my family. My Mum is a feeder and despite the fact she has a heart condition and my Dad has Type 2 Diabetes they don't have a clue about food. My Mum can't understand why they aren't losing weight and she seems to think that because she bakes her own cakes that somehow this is better... yeah, it contains less processed crap, but it contain just as many calories!
That's not to say they're not proud of me. They always say how they can tell I've lost a few pounds in my photos and I give them a weekly update on how much I've lost and they're supportive. But I'll be going home for a month in February and as much as I am excited about my Mum's cooking, I am worried about undoing a lot of progress. But I am hoping with exercise, a stiff chat with my Mother and working out my own portion size, I'll be able to eat pretty well.
I suppose I find their attitude to food so baffling- it's like they just have no idea how many calories they are putting in their mouth!
Anyway, that's my mini-rant for the day! Off to cook tea!
