Look at your slower losses this way: you've learning what your body doesn't like (tomatoes and hamburger). This is really helpful. Had you been eating chicken, as well as fish, your losses may have been greater. You are experimenting and learning how food impacts your body - and, hopefully, will continue to incorporate this knowledge well after HCG. Stay on course with 40 days, you will lose more pounds and inches and continue to lose inches in P3/P4.
