Tony, in theory you should be able to remove 1 pound every 2 days or so, especially if you are particularly heavier (and since you aimed to lose 100 pounds, I am assuming you are in the 280+ range).
give or take, 3000 - 3500 calories is a pretty good representation of a pound of body weight. If your weight loss is 2 pounds a week, you can typically move that up to three by eliminating about 500 extra calories a day, or doing 500 calories more exercise / work, or some combination of both.
if you can do two, you can almost certainly do three. It is always worth it after a few weeks to go back and look at what you are eating and what you are doing, and making adjustments to decrease the calories a little bit more and increase the activity a little bit more as well.
Remember also, as you get lighter, your body needs less overall calories to function. Most heavier people forget this and plateau after a while because they continue to take in food on the basis of making their larger body operate. As you get smaller, your body needs less energy to operate, and will start to convert excess back into fat. So you have to be careful and keep a sharp eye on intake and activity to make sure you are adjusting as their weight comes off.
You have taken the first big steps in a long but hopefully rewarding journey. Keep it up!
