I've been on ideal protein since November 15, 2013. I weighed 171, my goal was 135. I lost an average of 2 pounds a week. My total loss was 25 pounds, which at that point I phased off for a week as I had a mexico trip which was planned long before I started this program. When I came back I immediately went back on the program, which was February 10th. Since I have gone back on the program I have lost 7 pounds in a total of 10 weeks (feb 10 to now). Most weeks have been a zero loss. It is extremely discouraging as I am 100% on plan all of the time, but I'm not seeing results like I did before I went on vacation. I'm just wondering if anyone else has had similar issues?
