So far in 23 days I've lost 5 lbs

Started mid April at 175. Now in Round 2, so far in 23 days, I've lost 5 lbs. I started July4th at 156 and now am stalled at 150. This round 2 has been slower and I have stalled 3 times. I'm going for the 40 day cycle to see if I can lose some more weight. The 1st round, I dropped 16 lbs in 40 days. Don't know why this is tougher but it's still worth it.
