chloe is right. Sometimes you don't lose any weight for a while, maybe a few weeks, and then suddenly you lose a lot. Have you taken measurements around your waist and arms and jazz? sometimes you lose inches, but not weight cuz you gain muscle but burn fat. Keep up the work, don't give up. You made it this far, so don't turn back soon;-) You won't gain it back unless you overeat. Make sure you're exercising too. ;-)
