I must confess that I find it a little frustrating when people say that it is 'easy' for men to loose weight. Purely biologically speaking, it is 'easier' for a man to loose weight than a woman... but that's doesn't make it easy. And, as was alluded to earlier, there are complex social factors that contribute to a male weight loss being difficult.
If weight loss was only about biology, and not related to what is in our minds, then yep - it'd be much easier for men.
Many men naturally manage their weight, notice (usually without scales!) that they are putting on a few pounds and naturally make healthy choices for a little while. But those who are unable to do that are often in a pickle.
Whilst it is probably socially more acceptable for men to be overweight a few pounds, it isn't socially acceptable for men to be very overweight.
I was about 4 1/2 stone overweight when I started dieting, and I've lost 3 1/2 of it. I went to Slimming World and my class, in the middle of a cosmopolitan city, had me, one other bloke and about 30 women. The support structure just isn't there for many men. Whether we like it or not - diet clubs are for girls. Of course, that's a bit ridiculous and men should just join up anyway... but it can feel a little odd given all the marketing, promotional material and so on are related to women.
You know, Slimming World have an annual big competition where they offer 'Slimmer of the Year' awards and so on. And the woman Slimmer of the Year gets about £5k more than the man! Of course, they'd justify it by saying that many more women enter etc etc, but it's those kind of subtle (and not so subtle!) messages to men that diet clubs are not for them (or they'd that be welcome, but only as an afterthought) that make things very difficult at times.
It's easier for me as the whole manly butch emasculation crap kinda goes out the window, given I'm gay. You often find that there's not much point worrying about being embarrassed in front of other men because you're going to a diet club or something - when you've already committed the major sin to masculinity of being gay!
But I do feel for some men who are in a pickle and struggling with their weight - although it might be biologically easier, it can be socially much harder to get weight off because of the sheer lack of support systems made available for men.
