Nutrition Criteria

Excerpt of Article written by John Berardi, Ph.D. | Precision Nutrition

Perhaps you learned what you know about nutrition from family – what you were told at the dinner table growing up, what comfort foods you ate.

And of course, no one is immune to the influence of the media – heck, every 3rd talk show is about food and dieting.

Here’s the point:

Most of what folks know about nutrition was taught to them by people who know little or nothing about nutrition!

And worse yet, most of that information gets hammered home without you even knowing it.

So let’s start from the top.

The 3S Criteria

Once you change these rules and habits, everything changes: the way you eat, the way you sleep, they way you look, the way you feel when you wake up in the morning, the way you perform – even the way you think.

To do that, you first need to know how to evaluate a nutritional strategy. I teach my clients to use The 3S Criteria:

  1. Simple. Are the rules easy to follow?
  2. Science-based. Are the rules based on sound scientific principles?
  3. Successful. Have the rules produced success in others like you?

A system based on those three things is absolutely critical.

Are your [nutritional] rules based on simplicity, science, and success?

Have your rules produced the desired effect – a lean, healthy body that you’re able to maintain; a body that you’re happy with when looking in the mirror?
