Hello. Need to lose two stone!

Hi there. I am female, 30 and I need to lose two stone. Not interested in fad diets or anything but would quite like some help staying motivated.

My problems are socialising and eating too much cheese.

Aiming to eat around 1400 calories a day. I'm only 5 ft 2 so I'm thinking that's about right. Am 11 stone 3 at the moment.
