I can't do it alone

I've only just joined and hoping I can lose some weight and become more active. I couldn't do it alone, especially when others around me are eating 'naughty food' all the time. I am 31, female and live in the UK. I only want to lose a couple of stone and turn my fat in to muscle, but it is so difficult when you have no motivation and a mega sweet tooth.

I lasted 3 whole months of eating 'clean' food a few years ago and incorporating exercise in to my every day and this time I've only lasted 2 weeks before my naughty tooth got the better of me and I had some crisps and pizza!
