How low did your body fat percentage get down to? I've been 'mostly paleo-ish' for two years. I know people who have been strict on the lifestyle. There are only health-gains talked about. By low carb, do you mean you avoided vegetable carbs too? Did you try "no wheat/gluten/processed foods" but still a metric tonne of veggies and non-lean meats?
I did paleo for 9 months. No wheat, gluten. Veggies, some sweet potatoes and nuts, lots of meat (lean and non-lean). I lost 30 pounds (I wasn't really overweight). I don't know my body fat % at that time but I pretty sure it was lower than 15%. Exercising 3 times a week (Weight training).
I had carb craving all-day long even after eating 2000+ calories. I was between 50g and 100g of carb per day (as recommended by Mark's Daily Apple and some others). At the end I feel bad, always tired (exact opposite than at the beginning) and I got very sick for a month (first time in my life).
I'm now eating fruits and protein (no wheat, gluten, processed food) and sometimes dairy. I feel far better for more than a year now (without fluctuations like with paleo). I've gained some weight (because my metabolism was really low) but I'm now dropping weight without any change. It is a long-term diet I'm not expecting to drop 10 pounds in a month (I've tried paleo again for a week recently and didn't even lost a pound BTW).
A lot of people lose the carb craving after a few days, but it doesn't work for everybody. While I didn't "crave" carbs per se, I really did not enjoy not eating bread. What really worked for me is skipping breakfast and skipping carbs for dinner (just meat and veg). Even though I don't do that every day due to social events, I can lose 1lb/week or so without much trouble.
30lb/9 month is pretty impressive, good luck with your endeavours!
