I'm now 43, stopped eating carbs November 2011 -- was over 320 pounds; pre diabetes ; liver inflammation ; hyperlipidemia ; et.al.
My basic / only focus the first 12 of the past 18 months was keeping carbs around 20 gram per day.
The recent ~ 8 months, I have gradually made more Primal food choices, began IF once or twice a week, Primal exercise -- I'm slow to write up -- sometime soon I intend to post an in depth report of what I did -- my best statistics are going from 50 inch waist Levi jeans to 38 inch designer slim jeans ; all metabolic syndrome lab work now 'pristine' (quoted by my personal physician)
So many other amazing pearls to note; my lifelong-size-6 wife took up low carb fall 2012 and now is wearing size zero...
I ruptured bicep tendon in February turning doorknob...unusual winter and behind on many projects now
Many thanks to Sisson, Taubes, Attia and the many that post here on this forum and others like it.
