I do a few things that really help. The easiest is to cut you meal portion in about half. Americans have gotten so used to huge portion we train our bodies that we need it. I'll still have a P&J for lunch now and then, but not 2 or 3 like I used to. Another thing is to never buy anything at the grocery store, other than fruits and veggies, that doesn't have to be prepared to eat. Anything you can eat before you leave the store is bad. Anything that you only have to heat up as well. And to fight those late night hunger pains before bed, have a glass of water. Ive been drinking that fruit flavored stuff lately and its really good. Zero calories. Lastly, anywhere I can walk I do if weather permits. I can walk to the grocery store and video store near my house about as fast as I can drive there when you consider parking and lights.
