Draft 2: 9 January 2024

My last draft really went off the rails, because I got too far into the biohacking mindset. At the base minimum, I should be consuming:

Below, we see that,1 at the absolute minimum, I can meet this in a smoothie that does this relatively easily. Since the fat and carbohydrates are incredibly simple to achieve, it’s worth considering what 90 grams of protein otherwise looks like. Common ways I get protein are:

To get 90 grams of protein from each of these sources, I would need to consume2:

In the future, I’ll hopefully figure out a way to take these numbers and construct a meal plan out of them.

Draft 1: 9 January 2024

First, it appears that I was wrong in yesterday’s musing. The oil requirements are just straight up grams per day, which makes my life significantly easier. In order to hit my nutrition goals, I should be consuming at a minimum:

That is very little, and in total seems to add up12 to around 2300 calories. If I choose better oils for alpha linoleic acid13, that number drops to 1222 calories per day. If I price out my costs,14 to hit the minimum I need for nutrition:

Total cost for the base need smoothie comes out to around 7 dollars and 10 cents.

If we swap the gelatin out for egg whites, we get a little bit of carbs, but, assuming the cost is only in protein15, we can start pricing out the price per gram of protein for different foods:

Gelatin and egg whites are both about 1.6 grams per gram of protein, whey protein is about 1.1, and pinto beans are about 5, so it does require significantly more bean consumption. It also takes me well over the minimum carb load for the day, which also saves me 30 cents in sugar. It would, however, require consuming a full pound of beans18 each day. Egg whites probably strike a good balance of volume and cost.

Now that we have gone through this, we also need to remember the whole “there is a limit of calories I can, or at least should, consume in a day.” At the 3500 calorie mark, that means everything needs to be under 40 calories per gram of protein in order to be a valid source of all protein I consume.

Also, if I do the insane thing of bulk buying gelatin, I can get it for as cheap as 40 percent the cost, bringing it down to 3 cents per gram, which is honestly kind of tempting. It does, however, require purchasing 50 pounds of gelatin, which would serve me for around half a year. It would take us down to under three dollars a day.

According to the USDA, as long as I’m spending under 10 dollars and nine cents a day, I’m doing well.

This has absolutely degraded from the initial goal of figuring out how to feed myself well, for all that it would, without a doubt, be a very easy and effective way to get myself all of the nutrients I need in a day. I do wonder if I would be able to eat enough fruit and vegetable in a day to feel satiated.


  1. ooh an unconsidered benefit of drafts

  2. going off of USDA’s food search

  3. I assume the usual 2:1 water:rice ratio many use, and that the entirety of the water is into the rice, so I divide the USDA’s protein by 3

  4. assuming white long grain, which is my usual

  5. assuming the same water absorption

  6. assuming cooking doesn’t change the size much

  7. which, I do note, means that it’s almost all protein, since each gram of protein is 4

  8. same assumption as fish, which will go forward as needed, and assume that the grains expand the same tripling

  9. which weirdly gain a gram of protein when fried

  10. which according to Wikipedia at time of looking, is about half of corn oil, so 34 grams of that

  11. which wikipedia claims means about 160 grams of corn oil, or 4 grams of flaxseed or linseed oil

  12. assuming corn oil is my only oil choice

  13. better here meaning optimal

  14. assuming gelatin, sugar, corn oil and linseed oil all priced from my local grocery store that lists prices online

  15. true to a first order

  16. I’m remembering something about bioavailability, but that’s probably not too relevant, skimming an abstract, I see that all animal sources basically fine. Soy also approx 100, as is potato, interestingly. Oh wait, this is percent of amino acid intake, which have requirements in the mg/kg/day, which is so much less as to seem irrelevant to me; I’ll just trust protein labels.

  17. this article claims it misses lysine, threonine, and methionine.

  18. raw, then cooked
