Weekend Fun

We are heading to Mesa Falls today so look for the pictures in the next couple of days. And I need help! I am trying to be good and eat healthy, but due to my size and slow turtle like metabosim it is hard. I do well until dinner times then I don't cook at all or what I do cook is too heavey of a meal for dinner time. What do you do? Do you say "As long as I get on the tred mill in the morning I'm eating whatever." Or do you make your dinner the smallest meal of the day and how do you do that?
