To answer the question, I would say yes! I have successfully re-integrated carbs after LC, primarily because the re-integration has not made me gain any additional weight at all. The I began at 163lbs on SAD. Cut down to 148lbs at my low in January 2011. When the pics taken on March 19, I was 151 pounds. Since then I have added about 7 more pounds of muscle and I'm back up to 158 with no flab.
As for the other issues that I am still working withare , much of it is largely "question marks" and so there is some speculation at this point. I have only one single physical ailment... the unsettling feeling in my chest that comes and goes. On paper, I have a concern about my lipid numbers, particularly that I tested for low HDL at 40 and that my LDL was shown to be primarily small dense pattern B. If I can correct those 3 things... (chest, HDL, LDL type), I will be very happy because otherwise I feel amazing. I'm not a big guy at 5'8" 158, but I'm very strong, muscular, and confident. Very fit and able. Full of energy and zest for life. I think those details are very important because I'm pretty close to feeling optimal in life, which does speak well for eating mostly whole, quality, natural foods in today's world of availability.
