I'm not sure if this helps, but I lost weight by studying what made me eat.

Any reasonably strong emotional stimulus, whether good or bad, sent me to the fridge or the nearest fast food joint. I still do this if I get excited, angry or otherwise animated, but I always have fresh coffee on the go and I hit this first. By the time I'm halfway through a cup, the "spike" in my appetite has passed.

Also, being cold around the house often makes me eat without realising. Since I whacked up the thermostat I'm always on the warm side and rarely snack.

Neither of these may work for others, but then again they just might.
