Jessica, I am caucasian with family from Armenia and Bulgaria. Right now I lift weights once or twice a week, no cardio, but that was not the case for many years. I've been morbidly obese since the age of four. I started doing Atkins induction at 280 when I was 10 and switched to ZC at 400 when I was 23. I used to suffer carb cravings and hunger on Atkins because I never ate any fruits or vegetables and would try to get my 20g from grains, starches and sugar. This was the main reason for starting ZC, also I hoped it would get me past plateaus without having to reduce fat or protein (it didn't). Basically, given my previous diet of only meat, dairy, grains, starches, and sugar, doing paleo and doing ZC were one and the same. My lifestyle is healthy right now, though not perfect. I used to smoke and was into partying a lot. Surely, I would be type 2 diabetic like most of my family were it not for VLC. So ZC is definitely something that suits me for unique reasons but I am a firm believer in ketosis as a superior metabolic state. I also recently started doing weekly 100 hr water fasts to get my weight under 275 (im now under 250 for the first time in 18 yrs). I tried doing IF every other day as well as calorie restriction but both of these drove me insane. I'm not worried about muscle loss from the fasting because I was well adapted to ketosis before starting and I stay ketogenic during my feeding days. I actually got the idea to try this by researching the feeding pattern of lions after a large kill that took 2-3 days to eat. I hope I didn't spam this thread with too much about me, but thanks for asking.
