Recently went to whole foods and dodged some hippies to get some better dairy/beef/fat.
Unfortunately, they only seem to have low fat grass fed beef. Meh. But they do have fully fat grass fed steak.
They do have a way better selection of dairy. They've got pastured butter and yogurt. And I have to say that Whole plain yogurt + lemon flavored fish oil = the best food ever. Beats the fucking shit out of yoplait. (pretty expensive though).
It's amazing how easy it is for me to put on weight. Gained 14 pounds in two weeks (vacation, ate whatever I wanted, and I wanted a lot) after losing 80 in 6 months. It was actually great motivation to continue eating right now that I'm back home and back on low carb.
That's some serious hunger. Must still have some leptin resistance & insulin resistance going on. I'd try adding active yogurt/probiotics to the mix. I really like this gut flora theory because it explains why some cultures can eat lots of starches and never develop insulin resistance, why babies are obese now (because formula doesn't have probiotics like mother's milk, and it's full of sugar), and why adults are obese now (anti-biotics sterilize intestine, sugar/grains supports bad bacteria).
That's basically the equivalent steps of the rat study.
antibiotics (sterilize) + bad bacteria (supported by sugar, unopposed due to absense of good bacteria & it's fiberous food) => leaky gut => various auto-immune problems => auto-immune of hypothalamus and/or indirect inflammation of the hypothalamus => leptin resistance => persistant hunger.
It could be that low carb tilts the scale in favor of good bacteria through the elimination of sugar.
Of course it probably doesn't explain all cases, but it's always good to rule out all possibilities.
Fructose can be the direct cause in some cases.
Because you aren't what you eat. You're what you and your bacteria digest.
