Low level restriction can be tricky to even identify. I kept being surprised by it. You've done something for years. You do it automatically. You're maybe not even thinking about why you started doing it. You just measure that cereal, or make sandwiches with one piece of bread, or don't let yourself snack, or buy the "light" version. I'd ask myself, "Why am I doing this? Do I even like mustard? Wouldn't I rather have mayo? Why can't I eat after dinner?"
What I realized was that a lot of those default actions contributed to being less satisfied. So, I'd think about food more, I'd experience cravings, I'd have trouble stopping eating, and I'd later eat in ways I didn't like. Not only was the low level restriction not helpful for weight control (its whole purpose), it was causing me to struggle with things that satisfaction shuts all the way down. The miracle of satisfaction is that you're not hungry, you're not even thinking about food. That satisfied state is actually far more conducive to a stable healthy weight than hunger + crazy.
Staying in the moment and eating for satisfaction right now heads off a whole lot of struggle and chaos.
