I really think for me it's too much dairy in the diet.  Milk and ice cream especially.  2 of my favorites that I over eat on when not on the diet.  I also think that's why my weight falls off so fast when I start the diet.  I quit the milk and ice cream and in two days 5 lbs came off.  Wife says I didn't set the scale right on day one, but I know I did and checked twice both days.  Tomorrow is day 3.  I probably sweated some off today in the heat cleaning out a bin.
