Although there are many theories on the best way to automatically generate soylent recipes, so far only 1 has been attempted:

The purpose of this skeleton project is to provide a base from which developers can work on other ways to generate soylent recipes automatically.

This first version lets you access the ingredient and nutrient targets from any of the recipes on the DIY Soylent website. The base example is the popular "People Chow" recipe.

For a detailed discussion on generating soylent recipes automatically, see the thread on the Soylent forum:


A successful implementation would, given a list of ingredients, generate a recipe with close to 100% of each of the nutrients in a given profile.

The API should look something like this:

generateRecipe(ingredients, nutrientTargets) {

    // code to generate recipe

    // return an array of quantities in the same order the ingredients were provided in.
    return ingredientQuantities;

A nutrient profile looks like this:

var nutrientProfile = {
    "name": "U.S. government DRI, male 19-50, 2000 calories",

    "calories": 2000,
    "calories_max": 2100,
    "protein": 85,
    "protein_max": 90,
    "fat": 65,
    "fat_max": 70,
    "calcium": 1,
    "calcium_max": 2.5,
    "vitamin_c": 90,
    "vitamin_c_max": 2000,

Ingredients look like this:

var ingredients = [
        "name": "Masa harina",
        "serving": 100,
        "unit": "g",
        "calories": 365,
        "protein": 9.3,
        "fat": 3.86,
        "calcium": 0.141,
        "vitamin_c": 0,
        "name": "Now Foods 100% Whey Protein Isolate",
        "serving": 100,
        "unit": "g",
        "calories": 110,
        "protein": 25,
        "fat": 0.5,

Note that the 'serving' and 'unit' properties denote the quantity of an ingredient the nutrient amounts relate to. For example, in the ingredients above, 100g of Masa harina contains 365 calories and 9.3g protein.


This project was implemented in Javascript so that, if a successful solution is found, it can be re-incorporated to the DIY Soylent website. The idea is that any user could automatically reconfigure a recipe to their nutrient profile.
