Oh the shame... I couldn't understand why my epic post earlier wouldn't actually post, and I've just realised it's because I'd exceeded the MN maximum word count. I've shouted so much shit that it censored me!
I'll have to split the post. I didn't get anywhere near the end of the thread, either. 
Great post from Googoo and I can echo that too.
I lost 24lbs, so nearly 2st, last summer on bootcamp. This isn't a crash diet that will drop vast amounts of weight quickly (apart from the glycogen/water at the start), but a sustainable, enjoyable way to lose weight which gives multiple health benefits. I also don't think it's the only way to lose weight and keep it off, but for me personally it' the one which suits me best. For me the 5:2 is hopeless because as soon as I'm really hungry my will power flies out of the window and hunter-gathers lots of unsuitable foods for me to fall into. Low GI is also a healthy way of eating, ime, but you have to watch the fat content and I seem much more likely to stray into refined carbs and fall off the wagon, whereas low carb seems to really reset my palate.
It is hard to begin with, there's no denying that. Carbs, sugar and comfort/emotional eating are very hard habits to break. I have always been a person of excess, and was lucky that I got away with eating absolute shit and not really gaining weight until my thirties. I always knew it would catch up with me eventually, especially once I gave up smoking and various other vices. I don't want to live from one sugar (or any other kind of) high to the next, and I don't want to feel the need to dive into a tempting carb or glass of wine every time I'm upset about something. As I've said before, my issue is as much/more with emotional drinking than eating, I think, although I definitely do both. I find it much easier to resist the siren song of the wine when I'm low carbing because I can more easily close down the dialogue in my wheedling brain when I'm not hungry/craving sugar.
But, and it's a BIG BUT... The sugar cravings only subside if you really do give it a couple of weeks of hardcore discipline. If you're still having slips and mistakes, it just feeds the addictive cycle - your body doesn't get a chance to reset itself and start to taste the natural sweetness in non-carby foods. For the people who have wobbled/are wobbling/will wobble (because we all wobble at various points, I know I do), please try to keep in mind that if you can just resist for one or two solid weeks (and I mean no slips at all), then the sugar cravings do subside. When you've had a shit day, or a wonderful social invitation, or there's a pizza/cake/biscuit/whatever sitting in front of you, just chant "it's just for today/a week/two weeks/ten weeks/whatever time scale you can deal with, i've got the rest of my life to comfort eat/go out for a meal/eat takeaway". If after a few properly low carb weeks you're still hating the food then maybe this WOE isn't for you, but give it a chance. I also think that during that time, although it's really hard to do so, don't focus too much on the weight loss. The point is to break the sugar addiction and change habits, and I really do feel that a body which has been subjected to lots of diets and weight fluctuations has become conditioned to hold onto the fat for grim death. Trust, I think, is what is needed, both in the rational brain in trusting that this WOE will work and is worth sticking with, and trust within the body that it's not suddenly going to be deprived and hungry again.
I read a very good book recently called The Happiness Hypothesis, and he talks about our rational mind (the cerebral cortex, basically) being the rider sitting atop the elephant of our subconscious and instinctive brain (that's a massive simplification of what he says, actually, but I'm happy to go into more detail if anyone's interested). So we, the rider, can make all of these idealistic plans about giving up carbs and sugar, but if our elephant spies a doughnut and, in true Homer style goes "Mmmmm.... doughnuts....", there's sometimes sweet FA we can do to stop it charging over there and gobbling it up.
Wow I'm really shouting the shit this morning, aren't I!
I got a bit carried away.
