I've been reading Tom Naughton's Fat Head blog and watching his various videos. from the "Fat Head" movie (which you can watch free on Hulu) to "Science for Smart People" (which you can watch free on YouTube) and "Big Fat Fiasco" (which you can watch free on YouTube). I find these to be both amusing and (somewhat) informative. I'm not sure how much science there is behind the explanation of how insulin resistance causes you to get fat, though. It sounds sensible, but so does the lipid hypothesis, you know.
However, that being said, the biggest recent change I've noticed is that I now get hungry in a reasonable sort of way (and I want reasonable amounts of food). Today I had some beef liver pate and celery sticks for lunch, and now I'm hungry and making chili (no beans) for dinner. I was hungry around 5pm and it's almost 10 now. If I'd gotten hungry around 5 before, by 10 I would be an absolute wreck, shaky, feeling half-frozen, possibly even passed out in bed. I feel fine. I'm not tired, (I am hungry), but I don't feel wasted and shaky.
So that's good, at least. I'm going to track down a scale so I can weigh myself. It's been approx. 2 months since I started so I figure the water weight loss has mostly ceased and now I can actually get an idea of how much I weigh and what/if I'm losing.
