I KNOW how you feel about being SOOOOO CLOSE! I've found that as I lose more weight I need to decrease the amount of calories that I eat in order to see any change on the scale. I had a few days where I ate 500 more calories than usual, and I went into a stall!
I'm now eating about 1500 to see if that works. I exercise a couple times a day-Turbo Jam or walking or step aerobics in the morning and then ab work, yoga, and/or weights in the evening as I watch TV.
Up your fiber and water. Both will help eliminate all the toxins that the fat burn releases. Watch the carbs. I was doing WAAAAAY too many of them for a number of days and came to a stall right quick!
Good luck with your ten pounds! You WILL make it by the 30th! Keep exercising and you'll also get a bonus of a firmer, tighter body that loses INCHES as well!
