Pete, since today is the last day of July you can weigh in tomorrow morning for July's weight loss. Stay on track. Perhaps you are retaining water? One thing you can try is having a TBSP of Apple Cider Vinegar in a cup of water. You could have it at least two times today to try and flush some fluids. I know I did not win the batiks but considering I was vacationing. for two weeks and had to be inactive for a couple of days after getting home due to a sore knee I am happy to still be down one pound for the month and not up 10. I was actually up 4 when i got home but have happily gotten back on track and lost that plus one.
Good Luck.
