Life Performance Blog: Does Only Eating To 80% Full Really Work?



Why “80% full”? First: The exact number isn’t important. “80% full” is just an idea of eating a little less than you normally would. 80% full is about two things:

1. How much you eat.

2. How it feels to eat that much.

So by doing this habit, you’ll learn:

1. What portion sizes work for you.

2. What it feels like to be physically hungry, satisfied, and/or full.

In the beginning, you won’t know what 80% full is for you.

You probably won’t know what 80% feels like, or what portion sizes work best. That’s OK.

You’ll experiment.

Here are two techniques to get you started.

Eat slowly = 80% full along with eating slowly, 80% full is one of the two most important “anchor habits” in nutrition coaching.

If you can master only two nutrition habits , make them these habits. (Seriously. They're that important!)

And they work together.

The better you are at slow eating, the easier 80% full will be.


So in the beginning, as you learn what 80% looks like for you, go slow.


1. Take a bite.

2. Stop.

3. Take a breath.

4. Check in with yourself. How do you feel? Pause to notice.

5. If it feels like another bite is a good idea, take another bite. And repeat.


6. If you feel like you might be around 80%, stop.

That’s it.

Stop eating sooner than you normally would You probably have a sense of how much you normally eat — what size of plate you use, what size of sandwich or coffee you order, etc.

So you can:

1. Start with what you’d normally eat.

2. And then just shrink that a little bit. Or stop eating just a little sooner than you normally would.

For instance, try:

• Purposely leaving a couple extra bites of your meal on your plate.

• Ordering one size smaller than normal. • Using a smaller dish than normal.


Another option: Plan a workout or brisk walk shortly after you finish eating.

What to do today

1. Stop eating before you normally would. Don’t stress over the “80% full” and how to quantify that yet. If you stopped eating a little sooner than you normally would at every meal, then tick off your habit.

2. Eat slowly. This "anchor habit" will make your new habit of "80% full" much easier.
