The number one thing I have found to losing weight is portion control! Begin by leaving one bite of everything on your plate. Slowly let that bite left over grow into 2 bites, 4 bites, and end when HALF the plate is left. In America the portions are out of control, no one needs a platter or an all-you-can-eat to satisfy their bodies. Generally half a portion is plenty of fuel, and if you feel guilty about wasting food, take it home and save money and calories!
I used portion control to lose a large chunk of my weight in the beginning - it meant I could still have my burgers and ice cream...but logically not eating ALL of it resulted in lower caloric intake. For me being satisfied by eating what I wanted resulted in less snacking, and more weight loss!
