eat until you're 80 percent full

Here's an excerpt from Michael Pollen's book, In Defense of Food.

"Eat Less" is easier said then done, however, particularly in a culture of cheap and abundant calories with no deeply rooted set of rules to curb overeating. But other cultures do have such rules and we can try to emulate them. The French have their modest portions and taboo against seconds. The people of Okinawa, one of the longest-lived and healthiest populations in the world, practice a principle they call hara hachi bu: Eat until you are 80 percent full.

This is a sensible idea, but also easier said than done: How in the world do you know when you're 80 percent full? You'd need to be in closer touch with your senses than many Americans at the table have become. As Rozin and other psychologists have demonstrated, American typically eat not until they're full (and certainly not until they're 80 percent full), but rather until they receive some visual cue from their environment that it's time to stop: the bowl or the package is empty, the plate is clean, or the TV show is over. Brian Wansink, a Cornell professor of marketing and nutritional science who as done several ingenious studies on portion size and appetite, concludes that Americans pay much more attention to external than to internal clues about satiety.* By comparison, the French, who seem to attend more closely to all the sensual dimensions of eating, also pay more attention to the internal cues telling them they feel full.

*In one study, Wansink rigged up bowls of soup in a restaurant so they would automatically refill from the bottom; those given the bottomless bowl ate 73 percent more soup than the subjects eating form an ordinary bowl; several ate as much as a quart. When one of those hearty eaters was asked his opinion of the soup he said, "it's pretty good and it's pretty filling." Indeed.

At some point in the recent past, I realized the amount I was eating was often based on the amount I usually ate. I'd take a portion that I though was reasonable, and then go back for a little bit of seconds. I thought I needed to eat until I was full, but if I didn't go back for seconds, I was still full.

I've heard folk wisdom that one should stop eating when not yet feeling full because it takes a few minutes for that "I'm full" feeling to be felt, and if you don't stop eating until you feel "full", then you'll soon feel "too full".

Reading about that endless bowl of soup experiment....I'd have trouble with that. It's ingrained in me that wasting food is a disgraceful thing to do. I find it socially uncomfortable to leave food on my plate, even if someone has served me too much.

I do leave food behind if I "feel full", but it's always a displeasure, and I often feel "too full" about 15 minutes later. At restaurants, I will often ask for a doggie bag of the main dish, especially if I want to feel comfortable about having a taste of some [beautiful, delicious, dark chocolate] dessert.

That's true, and that's probably what's behind the Okinawans' philosophy. And also a difference between American and French cultures, regarding eating, as discussed in this book. The French eat more slowly, which means they receive the "full" sensation before they've eaten very much more.

It's ingrained in me that wasting food is a disgraceful thing to do.

That's common too. I know a lot of people who are or were overweight (not to imply that you fall into this group), because they feel they have to finish what was given to them. Or even what a family member left behind. They need to learn to put their health above their need to not be wasteful. Just consider easting food you don't need to eat. Isn't that wasteful too?

But to continue that thought, if eating too much is wrong, throwing food away is wrong too. So why do either? Take only what you need to begin with. That should be your goal. Therefore you need to learn how much you really need to be eating.
