When you are making a change in your diet, such as removing caffeine, AS, less/more fat, less/more carbs, etc., how long would be a good amount of time to give it to see if that makes a difference or not in your weight loss. I kind of get the feeling that a week would be good, but that really seems like a LONG time for some things (for example: my coffee ).

So how long did it take you to see or not see a change?
