Don't worry. You have started and now there is a chance to reverse it. Besides stress is bad too. Be happy you know what to do.
Keep doing what you are doing. For me, I went totally by what Mark said to do for weightloss and to convert my body from a sugar burner to a fat burner. I ate no sugar, not even honey or chocolate, for at least two months (and kept carbs to 50grams or less), before I added them back very occaisionally.
