Not eating at all is a lot easier for me than moderating my eating.
I'm a little hungry right now, but as long as I know that today is a fasting day, I don't feel seriously tempted to disrupt my plans. I can eat tomorrow, and I'll be going to sleep soon anyway (I hope).
But, for example, yesterday was a challenge. I had the Pork steak very late and about an hour later was poking around in the kitchen. It's like once I allow myself to go part way, I want to go all the way. Which is why I don't drink or gamble.
I did end up making some scrambled eggs and cheese after 10:PM, which pushes my window for tomorrow all around, but I'm going to stick to the plan rather than try to make up for a lost fasting period. I want to have my OMAD around 3-5 in the afternoon, and the sooner I adjust to doing that, the better.
