Primal Papa, you may have to experiment a bit with what you eat to find what works best for you. And give each experiment at least 3-4 weeks to see how it goes.
A lot of people say "eat more fat", but that doesn't work for all of us. I tried Paleobird's "eat moar fat" protocol, and I GAINED weight at 300 calories under my normal maintenance calorie level. More fat does NOT work for me. I tracked every calorie, weighed/measured every bite, monitored my fat/protein/carb levels very closely... and more carbs, less fat works better for me.
I'm not saying "eat less fat"; I'm just saying that things might work differently for you. I've read that some people have a hard time when they eat even small amounts of fruit; others can't lose weight if they include dairy.
And you might also want to have your thyroid levels checked, if you haven't already (I've been awake for 24 hours so my brain isn't in top gear at the moment... I don't remember if you've mentioned this).
The human body and metabolism is a strange and mysterious thing, and one size definitely does NOT fit all!
You make your choices, and you live with them. In the end, you are those choices.
