We’re on the Atkins diet here, and I wrote about it on January 29th. At that time, my most prominent side effect was increased grouchyness. That has receeded to its normal baseline.
It’s my waistline that’s changed. About 40 days in, and I’ve lost 21 pounds. I’m as light now as I was when I left active duty, and my clothes are much looser. My spouse has also lost some, though she chooses not to quantify it (or tell me, whichever). We cannot decide when to quit it, but this diet is so easy to stick with, even when eating out, that it’s not a punishment for us.
This isn’t an endorsement of the Atkins diet. There are several diets out there, and they all work for somebody. Find the one that works for you, and stick with it.
