10 Simple Ways To Eat Healthy Without Thinking, Backed By Science

Your environment has the incredible ability to shape your behavior.

I have written previously about choice architecture and environment design, both of which are focused on the idea that "by making small changes to the physical environment around you, it can become much easier to stick to good habits.”

While the research studies I have shared in those articles are interesting, I thought it might be useful to list some practical ways to apply environment design to your world, and make it easier to live a healthy, happy and adventurous life.

With that in mind, here are 10 simple strategies for designing your environment to eat healthy without thinking, and spend more of your time and energy on doing something awesome.

Keep in mind, these ideas are just a start. You can apply these concepts for designing your environment and creating better “choice architecture” to almost any habit or behavior.

How to Eat Healthy Without Noticing

Before we begin, let's give credit to the researcher behind many of these ideas, Brian Wansink.

A professor at Cornell University, Wansink has completed a variety of studies on how your environment shapes your eating decisions. Many of the ideas below come from his popular book, "Mindless Eating."

1. Use smaller plates.

Bigger plates mean bigger portions. And that means you eat more.

According to a study conducted by Wansink and his research team, if you made a simple change and served your dinner on a 10-inch plate instead of a 12-inch plate, you would eat 22 percent less food over the course of the next year.

On a related note, if you're thinking, “I'll just put less food on my plate,” it's not that simple. The picture below explains why.

When you eat a small portion off a large plate, your mind feels unsatisfied. Meanwhile, the same portion will feel more filling when eaten off a small plate.

The circles in the image below are the same size, but your brain (and stomach) doesn't view them that way.

This image shows how small portion sizes can look filling on a small plate, but sparse on a large plate.

2. Make water more readily available.

Most of us mindlessly take a swig of soda or a sip of coffee as we do other tasks.

Try this instead: Buy a large bottle of water and set it somewhere close to you throughout your day.

You'll find that if it's sitting next to you, you'll often opt for water instead and avoid less healthy drink options naturally.

Note: I love this bottle because it holds a good amount of water, and folds up small enough to fit in a backpack, purse or pocket. It's perfect for travel, too.

3. Want to drink less alcohol or soda? Use tall, slender glasses instead of short, fat ones.

Take a look at the image below. Is the horizontal or vertical line longer?

Like the lines in this photo, vertical glasses will look bigger than horizontal ones and will, therefore, naturally help you drink less.

As it turns out, both lines are the same length, but our brain has a tendency to overestimate vertical lines.

In other words, taller drinks look bigger to our eyes than round, horizontal ones. And because height makes things look bigger than width, you'll actually drink less from taller glasses.

In fact, you will typically drink about 20 percent less from a tall, slender glass than you would from a short, fat glass. (Hat tip to Darya Pino for originally sharing this image and idea.)

4. Use plates that have a high contrast color with your food.

As I mentioned in this article, when the color of your plate matches the color of your food, you naturally serve yourself more because your brain has trouble distinguishing the portion size from the plate.

Because of this, dark green and dark blue make great plate colors because they contrast with light foods like pasta and potatoes (which means you're likely to serve less of them), but don't contrast very much with leafy greens and vegetables (which means you're likely to put more of them on your plate).

5. Display healthy foods in a prominent place.

For example, you could place a bowl of fruits or nuts near the front door or somewhere else you pass by before you leave the house.

When you're hungry and in a rush, you are more likely to grab the first thing you see.

6. Wrap unhealthy foods in tin foil. Wrap healthy foods in plastic wrap.

The old saying, “out of sight, out of mind” turns out to have some truth to it.

Eating isn't just a physical event, but also an emotional one. Your mind often determines what it wants to eat, based on what your eyes see.

Thus, if you hide unhealthy foods by wrapping them up or tucking them away in less prominent places, you are less likely to eat them.

7. Keep healthy foods in larger packages and containers, and unhealthy foods in smaller ones.

Big boxes and containers tend to catch your eye more, take up space in your kitchen and pantry and otherwise get in your way.

As a result, you're more likely to notice them and eat them. Meanwhile, smaller items can hide in your kitchen for months. (Just take a look at what you have lying around right now. It's probably small cans and containers.)

Bonus tip: If you buy a large box of something unhealthy, you can repackage it into smaller Ziploc bags or containers, which should make it less likely you'll binge and eat a lot at once.

8. Serve meals by using the “half plate” rule.

You can design your eating environment as well.

When you serve yourself dinner, start by making half of your plate fruits or vegetables. Then, fill the rest of the dish based on that constraint.

9. Use the “Outer Ring” strategy to buy healthier foods.

The concept is simple: When you go grocery shopping, don't walk down the aisles.

Only shop on the outer perimeter of the store. This is usually where the healthy food lives: fruits, vegetables, lean meats, fish, eggs and nuts.

If you only shop on the outer ring, you're more likely to buy healthy foods. And that, of course, means you're more likely to eat healthy foods when you get home.

10. And for the tenth strategy, apply these concepts to some other areas of life.

When you break down each of these strategies, you'll see that each one is a small tweak that puts more steps between you and the bad behaviors, and fewer steps between you and the good behaviors.

For example…

- Wrapping unhealthy foods in tin foil adds another step. You have to see the dish, then open it to see what is inside, then decide to eat it. (Rather than just spotting some leftovers in plastic wrap and grabbing them.)

- Using small plates adds another step between you and eating more. If you want more, you have to go back for seconds and fill up again.

You can take this same approach to almost anything in life. If you want to make a bad behavior more difficult, increase the number of steps between you and the behavior.

Meanwhile, if you want to make a good behavior easier, reduce the number of steps between you and the behavior.

For example, if you want to make it easier to go for a run, lay out your shoes and running gear the night before you exercise.

That's one less step between you and your workout.
