OK, It's sexism for the sake of honesty time.
Ask a group of men what they like most about women, and generally, if there's no women in earshot, and they've had a tongue-loosening beer or two, they'll name three things:
The ass, and both tits.
Size zero essentially means you don't have any of the main 3 features guys like.
Sure, if you're dieting 'for yourself', go ahead, but don't expect the guys to be queueing up when you've gone from a healthy size 16 to 'Skeletor in a sleeping bag'.
Jo Brand, a rather large female stand up over here in the UK once said something very un PC - " We could fix the fashion industry in a moment by just getting rid of all the gay fashion designers, and get some more women in, then perhaps clothes will stop being made to fit the teenage boy body shape and fit a real woman. "
She's very obviously not saying she's the right size, she's pretty damn big, but she is saying, if you've slimmed down to the point where there's no sign of femininity in your silhouette, you've probably taken it too far and could be mistaken for a boy in a dark nightclub. (At least that's my take on it.)
Ok, it's dodgy to criticise a minority for anything these days, but why do we let men dictate what women wear? High heels are ridiculous for a start, even more so when you consider most men want to be taller than their partner, and most women want a taller man.
As for the set of questions:
Male or female? Male
Are you trying to achieve size zero? Yes, by eating so much that I die early and get cremated, that's the only way I'll ever hit that weight.
Why/Why not? Because I rate pleasure above being attractive to necrophiles.
What's your view of others trying to achieve size zero? Foolish and easily led by the media, I've never seen a size 10 woman and thought, 'oi fatty, put down the donuts', but then a size 16ish is ideal imo anyway, and the average woman in the UK.
What's your view of others who have achieved size zero? Well done, now go have some cake.
And most importantly, is size zero actually attractive? It can be attractive in the way art can be, someone can be pretty and size zero, but not sexy and size zero, imo.
