Estrogen and other fun stuff is stored in fat cells. As you lose weight it is released in your body where it gets to travel a bit, then is removed. Overweight women have a higher level of estrogen. You also have better blood sugar and insulin control. Then there is the fun withdrawls from carbs, sugars, and maybe caffine.

Then of course there are just really idiotic people in this world that seem to strive to be as annoying as possible.... Even non dieting or LC people want to throttle them
