Im down 20 lbs in about 3 months doing crossfit. Lost 10 of that the last 4 weeks after switching to Paleo for a little in-gym challenge we are doing.
+2 on paleo and crossfit, I went from 235 to 170 in about 4-5 months. It takes alot of dedication to want to improve, but stick with it you will get there. To me it wasnt all about the weight loss it was a comination of much healthier lifestyle, waking up refreshed every mourning with no pain, no sickness etc,etc... was my motivation.
