I do intermittent fasting because my wife started it a couple of years ago and I decided to go along with her.

For the first few weeks, I thought about it a lot. Eventually, however, I stopped thinking about food in the morning.
I usually stop eating at about 8pm each night and then I don't eat the following day until at least noon. Last Friday, I got distracted and didn't eat until after 5pm. I just hadn't thought about eating.

I don't think it's too hard most of the time. Once I start eating, however, I have a hard time stopping. I eat so much.

Regardless, I feel better physically than I did before I started it. I have lost about 5 pounds in the last year and a half that I started doing it, but I'm a thin guy without much weight to lose anyway. If I had more to lose, I'm sure I'd have lost a lot more.

My wife put on weight about 6 years ago during 4 pregnancies in 4 years (3 miscarriages) and all of that weight is long, long gone.

One serious drawback is that I don't drink during that span either unless I force myself to do it. I don't feel thirst until I start eating so sometimes I go 16 or so hours without drinking anything if I don't pay attention. I'm trying to do better in that regard because I worry about that having a severe negative long term impact.
