That persistent layer of fat covering your abs is there for you to expand to have a baby. All females have it.
I don't think anyone wants to look like Kim Smith in the first photo in this posting: http://paleohacks.com/questions/33826/do-you-aspire-to-be-an-elite-runner#axzz1OscZFnLM You can see her abs and every other tendon in her body also.
Trying to lean out so much just goes against our evolutionary melieu. Yes some of our pre agriculture ancestors leaned out due to starvation. But our goal is to live an optimized life and starvation is not optimal...just to see your abs.
I suspect with all your workout your cortisol levels are pretty high. Cruise over to Dr Kruse's blog and he has a lot of info on hypercortisolism... http://www.jackkruse.com
Read it all but I think Hormones 101 applies very well.
Accept your female evolutionary biology and work within it...not against it.
You are doing great in ketosis. Add a couple of yams a week and you will be operating optimally on the edge of ketosis.
With no wheat, sugar, or industrial oils, I suspect if you did a lipid panel your numbers would be great...but you might see a little higher than one would like to see in your C Reactive Protein due to all the exercise raising cortisol.
Congratulations on your paleo journey.
Edit: If you are not supplementing with Vit D3, you should consider it. It is great for strengthening your immune system. Dr Kruse wants his patients to be at serum Vit D3 70 to 100ng/ml. Most folks are deficient even if they are in the sun a lot. I maintain my level with 5000IU a day of Now Brand 5000IU gelcaps avail from http://www.swansonsvitamins.com I use this brand because the carrier is olive oil..not soybean oil.
