Eat healthy using choice architecture

Stress causes certain regions of the brain to release chemicals that can trigger mechanisms similar to the cravings you get from fat and sugar, so your brain feels the addictive call of fat and sugar and you’re pulled back to junk food.

Stress favors unhealthy eating

“I don’t” is experienced as a choice, so it feels empowering. “I can’t” isn’t a choice, is a restriction. 
In other words, the phrase "I don't" is a psychologically empowering way to say no, while the phrase "I can't" is a psychologically draining way to say no.

Words frame your sense of empowerment and control

<ul>
<li>Salivary response: the more a food causes you to salivate, the more it will cover your taste buds.</li>
<li>Rapid food meltdown: this tells your brain that you’re not full, even though you’re eating a lot of calories.</li>
<li>Calorie density. junk foods are designed to convince your brain that it is getting nutrition, but to not fill you up.</li>
<li>Memories of past eating experiences: When you eat something tasty, your brain registers that feeling and will bring it up in the future.</li>
</ul>

How craving are stimulated artificially

Most people think that building better habits or changing your actions is all about willpower or motivation. But your environment has an incredible ability to shape your behavior.

Building better habits means changing your environment

<ol>
<li>The sensation of eating the food: what it tastes like, what it smells like and how it feels in your mouth.</li>
<li>The blend of proteins, fats, and carbohydrates that it contains: junk food companies are looking for a perfect combination, that excites your brain and gets you coming back for more.</li>
</ol>

The reasons we crave junk food

At the store, only go for the “outer ring” , where the healthy food usually lives: fruits, vegetables, lean meats, eggs, etc. These are items that grew or lived outdoors. That’s what you should eat. 
The aisles are where all of the boxed and processed stuff is placed.
