First of all, I've been trying to lose weight for the past 3 years unsuccessfully. Over the past two years, with great effort (mostly starving on CW diets and over-exercising cardio for up to 5 hours a day) I finally managed to budge 10 pounds, and kept cyclically shedding and gaining. Some 'problem spots' never lost at all. Since being on primal for 3 weeks, my problem spots that have been with me since 11 years all started shedding weight effortlessly, and I've dropped somewhere near 5 pounds with little to no cardio. And this is my 'set point' now, I can't keep the weight on even if I try. This is miraculous to me after the long and futile efforts of the previous two years, and considering I'm at about BMI 19-20 which means losing weight should be very hard for me in the first place. Health markers have improved dramatically too, such as sleep, mood, BP, and boundless energy. Go primal!
