The fat that you eat isn’t any big deal if you leave out the starchy foods (pasta, bread, potatoes etc.)
Hard to do, yet I feel so much better personally when I cut out the carbs (veggies and fruits ok, but limit fruits if cutting).
Started grabbing stuff off of Livin’ La Vida Lo-Carb at itunes just to make myself realize that feeling better means eating better. I sleep better, have more energy etc.
