The ancient Stoic philosophers were very interested in food. They talk both about what we should eat and how we should eat it, if we want to live wisely and gain strength of character. 

What to eat 

We are told of the Stoic teacher Musonius Rufus’ thought that 

Mastering one’s appetites for food and drink was the beginning of and basis for selfcontrol. 

Inexpensive over expensive 

Musonius taught that Stoics should prefer inexpensive foods that are easy to obtain and most nourishing and healthy for a human being to eat. It might seem like common sense to “eat healthy” but the Stoics also thought we potentially waste far too much time shopping for and preparing fancy meals when simple nutritious meals can often be easily prepared from a few readily-available ingredients. 

Grains over meat 

Musonius advises eating plants and grains rather than slaughtered animals. He recommends fruits and vegetables that do not require much cooking, as well as cheese, milk, and honeycombs. The Stoic weren’t strictly vegetarian. Some Stoics were probably vegetarian and others not, although they wouldn’t have eaten very much meat in general. 

What Marcus ate 

In a letter to Marcus Aurelius, his tutor and family friend, Marcus Cornelius Fronto, jokes about how he saw one of the emperor’s little sons clutching a chunk of brown bread, “quite in keeping with a philosopher’s son.” In another letter, we get a glimpse of Marcus’ eating habits: 

Then we went to luncheon. What do you think I ate? A wee bit of bread, though I saw others devouring beans, onions, and herrings full of roe. 

How to eat it 

Musonius also thought we should train ourselves to avoid gluttony: 

Since this behavior [gluttony] is very shameful, the opposite behavior—eating in an orderly and moderate way, and thereby demonstrating self-control —would be very good. Doing this, though, is not easy; it demands much care and training. 

Eat slowly and mindfully 

Stoics should eat slowly and with mindfulness of their own character and actions, paying attention (prosoche) to their thoughts and actions. They should use reason to judge where the boundary of what’s healthy lies and exercise moderation wisely. 

Don’t eat more than you need 

The person who eats more than he should makes a mistake. So does the person who eats in a hurry, the person who is enthralled by gourmet food, the person who favors sweets over nutritious foods, and the person who does not share his food equally with his fellow-diners. […] Since these and other mistakes are connected with food, the person who wishes to be self-controlled must free himself of all of them and be subject to none. One way to become accustomed to this is to practice choosing food not for pleasure but for nourishment, not to please his palate but to strengthen his body. 

Eat healthy 

That very simply means making an effort to eat healthy food. However, for Stoics the main reason for doing this isn’t just to improve our health, paradoxically, it’s to strengthen our character by exercising self-awareness and the virtue of self-discipline. 

Don’t let contradictory advice confuse you 

We are bombarded with contradictory advice about the healthiest way to eat. The Stoics would say that we shouldn’t allow that to confuse us. We should make a reasonable decision and stick to it in order to develop self-control because that’s fundamentally more important than losing weight or becoming physically healthy anyway. To be clear, both goals are of value, but for Stoics the primary goal is strength of character and physical health, while “preferred” as they phrase it, is of secondary importance.
