Hi
Its hard getting into a diet isn't it? I have found the key to my motivation is not to view it like a diet. I use livestrong, which is free and allows you to track your food and exercise.
I tracked my food intake for a week, whilst I wasn't 'dieting' and to be honest i was horrified by the results. I had no idea i was consuming so many calories and that over half of my daily food intake was fat. Seeing it on the website (Which uses pie charts etc to illustrate) was shocking and made me feel ashamed.
So I've set myself a calorie goal just over 1000 calories less than my old average (which is still more than the recommended amount) and I'm making choices that help me stick to this. On top of that I'm exercising more, using the wii fit, so I can keep track of calories burned.
I know it sounds like a hassle but its really not. I lost 5lbs last week, granted its only the first week but I feel more motivated to keep going than I have in a long time.
Apologies for the long winded reply, I just know how you feel and thought I'd share whats working for me. Good luck with it, it isnt easy but with support and insight its a bit more fun! Hopefully see you around the boards
Nicola
