About a year and a half ago, I started running and eating (mostly) paleo at about the same time. I went from 150lb to 132lb to about 140lb now, but I lost and kept 3 inches off my waist. I haven't been exercising regularly, but have been able to stay healthier thanks to my diet.
My question comes from the responses from people that my weight loss was only caused by the running that I had done (training for a marathon) and not from my diet:
Do you think that the health/body composition changes you have experienced are caused by diet adherence, exercise, or both? What kind of evidence do you have to back it up (even n=1 evidence)?
For me, it seems that diet is of greater benefit because I have remained 80+% paleo, but still remain healthy; I'm not running 12-18 miles every Saturday anymore. In fact after the marathon 6 months ago, I hardly run at all.
