Part of losing weight is to have a mind set that you are ready to lose weight.
I'll be honest, I have to work at it. I have to physically make myself get up and do the treadmill thing and exercise. I have to write down all my food, I really do it twice, and I have to remember all day that I am losing weight.
It DOES get easier. Your mind and your body adjusts to the new calorie level. That's not to say I don't prefer NOT doing exercise on my off days. I really do.
But feeling better is worth it.
AND be patient!
