Basically, every diet works if you stick to it. You can do WW or SW without going to meetings, they do just online options and they'll work, if you stick to it. Calorie counting will work, if you stick to it. Atkins will work, if you stick to it. Dukan will work, if you stick to it. Lighter Life and the Cambridge Diet will work, you guessed it, if you stick to it! So I think the question isn't what diet will work, it's what diet is right for you, which isn't really a question that we can answer.
If you want to do SW, WW or RC but can't make it to a class then why don't you do it online and get some exercise in at home? I suggest taking a look a look at the different diets and how they work and what you think would work best for you.
Personally, even though I started with 6 and a half stone to lose, I didn't want to do a VLCD, been there done that. I don't deny that they work and I'm not saying that people shouldn't do them but I don't feel that it's the healthiest way to do it. I also don't think that, for me, removing food from the equation completely really does anything to retrain my thinking about what's healthy food, portion sizes, being controlled etc. I do calorie counting because, to be honest, I just can't be bothered to faff about with points and syns and things like that. It's simple and straight forward, it changes my attitude towards food and anything is allowed as long as it's in moderation and I stay within my calorie limits.
So really, the world is your oyster. Good luck finding what works for you.
