Welcome to the WISH group!
You have found the best place to start.
I want to add to the great suggestions you already have. Your mind must be in this. I would recommend going with what WISH stands for and really say it and mean it when you grab something to eat.
We're Inspired to Stay Healthy.
That in my mind (see I do try to get my mind in this--even if it is not always cooperating) means that it is not a Diet. Get rid of that D-word. You must convince yourself that you are making healthy choices for all that you will do. You need to know you are worth this and your family and friends need you to be healthy. It is a job. It is not easy for many of us. Yet, it can be done.
I like to use
FitDay.com to log all that I need. It is a little labor intensive in the beginning when you set up what you are eating. After a bit, it becomes a breeze. It does not contain absolutely everything, I sometimes get something colse if I need. The thing is what has already been suggested. To log all that you eat and try to get it balanced. Work on smaller portions as a life-style, and maybe splitting that into portions that you can eat through the day instead of at one meal.
The next is the exercise. Your body needs that. Walking briskly (increase the heart rate being the goal) not stolling, if you cannot afford those exercise tapes/cds try your library. When you figure what works for you then you might consider a purchase.
Water consumption is a must too. It will make a huge difference if you are not already drinking the recommended amount.
Keep a positive attitude.
Come here often to post and let us know how your are managing. We need everyone to make this work. Come often post lots!
Good luck with your quest.
