My soylent formula and sources, living in Ireland (most stuff comes from Amazon UK)
For one person, the setup cost is:
12 days initial: €243,04
24 days initial: €262,94
30 days initial: €272,89
Sustained daily cost for 1 person is: €5,27
All costs calculated without shipping, and at GBP 1 = €1,17
Planned taste: Strawberry and peanuts
Red/Bad numbers still need to be optimized (€0,46 for micros in ADDITION to the Multivitamin tablets? There must be better Multivits around…).
Green/Good numbers are as cheap as they get.
Dark green means included in another ingredient.
Proteins are okay at that price since the cheapest alternative still costs €1,73 per day, but has no flavour and is not the “No 1 brand”. I have 3kg of this brand here and I like the flavour enough.
Fat is to be experimented around with - I’m starting with peanutoil because I expect the taste to be okay.
For Potassium I’m sure there are cheaper alternatives than Gluconate, but those will be tried out later.
The only “optional” included at this point are Omega 3 fats - can add others later still.
2440 kcal - for me (1,80m, male, 25, 63kg, not too much movement) that’s a very slight weight gain. Hopefully.
Calcium tablets should be taken separately and not put into the drink - ideally leaving a bit of time in between drink and tablet. Omega 3 capsules are those gel thingies, they can be swallowed at the same time as calcium
All micronutrients (from Iron on, including the Omega 3s) are in tablet form and together come to €0,57 a day - I don’t think that has to be changed to separate powders ever (outside of industrial production), it just wouldn’t be worth the time.
The only thing that needs to be done is to find a better All-in-One tablet.
A kitchen scale exact to 1g should be sufficient, though 100mg would be ideal. No other equipment (except for storage) required.
For most Amazon items, the use of http://parcelmotel.com/ is required (as many items are only shipped to the UK).
Let me know if the file host is problematic for anyone, I just don’t like Google docs.
Also, disclaimer: I work in IT and financial services. I have no idea about nutrition, medicine or anything. I wrote this down as a way for me to keep things organized and can’t recommend anyone using it. If someone does try this…not my fault!
