Peter Attia recently summarized his nutrition framework into a 1 page diagram:

Breaking dietary modifications into 3 “levers” we can pull. These are:

  • CR – Calorie Restriction
  • TR – Time Restricted Eating (often referred to as intermittent fasting)
  • DR – Dietary Restriction

Peter says that in order to avoid eating the standard American diet, you want to be pulling at least one of these levers at all times.

For most people that’ll typically be dietary restriction; avoiding sugary foods, processed carbohydrates and trans fats.

However, ideally you want to be pulling at least two of these levers. Peter says he lives most his life like this, doing the following:

  1. Restricting how often he eats, typically eating his first meal in the afternoon (intermittent fasting)
  2. Restricting what he eats; currently he doesn’t eat sugary foods, and he doesn’t eat processed carbohydrates

Occasionally, you want to pull all 3 of these levers.

Pulling all 3 levers means doing an extended fast.

So let’s recap; you want to be thinking about:

  • What you’re eating (DR)
  • When you’re eating (TR)
  • How much you’re eating (CR)

Rhonda Patrick also touches on this in her dietary approach; where she practices intermittent fasting and limits unhealthy foods such as sugar, processed foods + more.

Pulling all 3 levers at once… fasting

These days most health conscious people follow some form of time restricted and dietary restricted eating. However, what can be a big leap for people is pulling all 3 of the above levers at the same time.

This requires doing an extended fast of at least 3 days, and ideally getting up to as much as 5 days. Having done 5-day water-only fasts personally, I can say that they’re not easy, and you generally want to build up to them.

To Recap

Peter’s framework breaks nutritional changes we can make (levers) into 3 categories:

  • What you’re eating (DR)
  • When you’re eating (TR)
  • How much you’re eating (CR)

At all times we want to be pulling at least 1 of those. Ideally we want to be pulling 2 of these. Occasionally we want to pull all 3 (longer duration fasting).
