I'm new here too, and also from North Yorkshire, and will be returning there in April.
I think 'dieting' is the hardest thing in the world when you're not ready for the change. I've dieted on and off for 10 years, but like you always found binging to be my number one weakness, that along with excuses, sooooo many excuses.
This time though, I'm 5 weeks in and 8kg and 12cm on my waist down, and I feel SOOOOO good and determined to keep going until I'm fit and healthy. I no longer binge, in fact (apart from an incident with a family bag of sweets last Sunday, which I saw off in ten mins) I no longer eat sweets/choc/cookies/crisps/donuts/cakes and all the rest of it, unless I make a rational decision at the weekend that I deserve a portioned controlled treat.
I'm not following a plan, other than only eating three good meals a day and NOTHING else Mon-Fri, and then thinking about what I eat at the weekends. I've also been adding exercise slowly, and am now up to 4 workout dvd sessions a week, which are killing me and making me feel great all at the same time.
I don't calorie count or weigh or measure. I use the knowledge we all have about good and bad foods when I decide what and how much to eat, and it's really working.
I wish I could share my secret with you. But I've no idea why things are different this time, it just feels like it's right, so I'm embracing that.
Good luck, small steps will make massive differences in the long term
