As someone doing a slow carb diet, I was pretty excited to read this. I have noticed in myself a huge difference in appetite-related issues. I switched jobs at one point for a job with much less pay, in part because all the travel I was doing with the related skipping of meals due to flight schedules would give me such bad headaches that it was crippling. I remember a bunch of times driving home from the airport with such bad pain I was worried about actually making it back home safely. And if I didn't have a bunch of snacks with me, even for an afternoon out, I would feel panicky. I didn't have a bad diet back then - I was never a fast food person or drank sodas (real or diet). But the standard "healthy" american diet wasn't working for me.
I switched my diet almost a year ago for weight reasons and it was a completed unexpected side effect that if I get caught now without being able to eat even til dinner, I might feel hungry but I am not at all sick. The higher fats do keep me from getting out of whack, whether it's from bacon or avocados. I'm 11 months in, I'm not sure at what point we declare things a success in terms of maintenance. I think I've read 3 years for a diet because that's the time it takes for our metabolisms to adjust to weight loss. If this way of eating means less adjusting of the metabolism - heck, that's another unexpected side effect I'd love to have.
