Transport, feeling and being healthy is a great motavator and you seem to be on your way...As Dakota and OVM said portion control is a big factor and one of the easist ways to get a handle on that is top using a full size dinner plate and use a 7 inch salad plate...sounds easy enough and yes it works as long as you don't heap the same big portions on the smaller plate...
When i was doing the personal chef business, weight loss was a speciality business we worked in and the 1st thing we did was buy the client small plates...if you put less food on the plate, don't go back for 2nds, you will eat less, and loss weight....
now you still need to follow your diet plan, but using a small plate while a head game in the being, works....
Good Luck to ALL of you that are dieting, its hard work, but to be healthy, it is worth it!!
