When I first started going low carb I was completely obsessed with food. It was all I thought about for several weeks. I have calmed down now and as I find out exactly what does work for me and how I react to certain foods the obsession has gone away. You do learn how to eyeball portions, how much of something you can eat and how many carbs you can consume and still feel good. You learn what you can order when you go out. It is just a time process.
