Some great advice given by Hope & Kim!

Just want to add, you need to have goals - what are you aiming to achieve? I am not talking about broad goals such as 'to lose weight'.

How much weight? By when? How are you going to achieve it? Are you going to weigh yourself once a week and measure yourself say every 4 weeks? (sometimes no weight loss on the scales but you have lost cms). What about when you reach that goal? You need to set new ones to keep you focussed..... The other thing is you need to make the change forever, not just for now b/c then the weight will come back....

Best of luck
