Let's talk about food! I've seen some questions about this. Of course, the rough dimensions to optimise are :
(a) money
(b) time
(c) taste
(d) functional effect on work ( whatever work you do )
All of us probably want to maximise productivity, so what remains is to haggle about money, taste, and time.
# Not at Home
So if you are getting good coin, then it makes total sense to just outsource and never cook - I did this for a few years while I was running a cafe. ( The coin was just enough, but the vendors nearby were cheap. )
# At Home
If you are getting good coin, and if you're based at home, you may enjoy ordering in - but (i) it may be very polluting due to absence of regulation on single-use plastics, and (ii) the platform owner is taking 30% of what you pay, so it is "value optimised" only if you have no other options.
The other options ...
## ... value : Taste Matters
Being at home, of course, if you are willing spend a bit of time on groceries and prep ( of course you could still get groceries delivered, then self-prep), then you get 30% better value-for-money by preparing food from superior ingredients. Whether you cook or eat raw, the nutritional output from your Ringgit will probably be higher than if if you order-in.
## ... value : Taste is a Distraction
This is what's in the picture below, and it's a bit "too much" for most people, but I enjoy it. The most spartan approach, being to science the sh it out of human nutritional requirements on a spreadsheet, and then to build a diet from the bottom up based on first-principles ( granted, mankind has not yet established super clear first-principles of biology, in general ).
There are a couple of aspects to consider here.
(i) minimising the cost of macros : fats, proteins, carbohydrates, fibre, and salt ... while maintaining peak output from muscles and nerves. ( Your heart, lungs, voice, and fingers depend on muscles ... your brain is clot of nerves ... this stuff IS applicable to white-collar work. )
(ii) hacky tricks which give you leverage via non-essential pathways : muscle synthesis triggers, co-factors in mitochondrial energetic pathways, etc.
There's always more to learn. If you're interested in commercial products for this sort of thing, you can always look for Soylent, which is like 10-years-old at this point - but it always seemed a bit expensive to me.
