Update: John Maxwell and I have a startup making nutritionally complete food, MealSquares (which is likely better for weightloss see below)
This came up at a meetup a while back. Several people, myself included, expressed frustration with the time, cost, stress, of preparing reasonably healthy and tasty meals. I suspect this frustration is widespread among people who do work that requires a lot of focus. Leaving flow because your body needs maintenance is annoying. So I'm sharing a strategy that has helped me.
I was encouraged by the success of Soylent. I had been playing around with ingredients for post workout shakes for months. But reading the Soylent blog posts inspired me to do a full micronutrient breakdown of what I had been drinking and optimize in a more rigorous fashion. Why not copy the soylent recipe?
1. I'm not realistically going to source all of those ingredients
2. He risks (and has already had problems with) misdosing himself to deleterious effect, this problem doesn't exist with whole foods
3. The absorption of powders vs whole foods is contentious
4. I don't agree with his criteria for inclusion
In comparison, my recipe is extremely easy and cheap to source, due to the small number of ingredients.
There is an immediate problem with meal replacement shakes in that liquid calories tend to have a significantly smaller satiety effect than solid foods. So this will probably not be a good solution for you if have difficulties keeping your overall caloric intake down.
[EDIT: Removed the link to the recipe, John and I are planning to commercialize this in addition to MealSquares at some point. Get in touch with me if you really need the recipe and won't spread it around.]
This is a work in progress and I am looking for further ideas for improvement. Subjectively I can say I find this recipe delicious, and hugely prefer it post-workout to even the best junk food (pizza, etc.). The combination of milk, vanilla, banana, and orange juice tastes kind of like an orange julius. It has also been a major stress relief and time saver. I don't worry so much about nutrient deficiencies anymore as this shake in addition to a meat or egg based meal has me pretty well covered.
I am due for another blood panel and will report any anomalies as I've been drinking a similar concoction for around 6-8 months.
I am open to debating the merits of my ingredient choices (as well as the overall wisdom of this scheme) in the comments. Also please share any other strategies you have for making food less of a chore.
Edit: I finally got my blood panel back and everything is looking good. Triglycerides unchanged, HDL up, LDL slightly down. All other numbers within the healthy range. I'm a little concerned about my iron level (what is considered normal may not be optimal for longevity), and plan on giving blood to lower it, but this is orthogonal to the use of a dietary shake I believe.
Edit: Kefir is expensive but highly recommended for lactose intolerant individuals. It is also delicious.
A few words of possible dissent.
If you enjoy cooking, then time spent doing it isn't a pure cost. Many people enjoy cooking. I happen to be one. You might turn out to be one too.
If you pay money for food, all the money is gone. If you spend time cooking, you can do other things with some of the same time -- if there is someone else around, you can talk to them; you can listen to the radio or (intermittently) read; etc. So beware of simplistic time/money tradeoff analyses.
Cooking is a useful social skill as well as a way of getting edible food for yourself. (You can invite people over for meals, which is by no means socially equivalent to inviting them out for meals.)
Good restaurant food is quite expensive. (Admittedly less so in the US, where I think you live, than in the UK, where I live.) If your tastes aren't cheap, eating out a lot may not be such a great tradeoff even if you regard your time as very valuable.
The time-cost of eating out is not zero. Depending on where you eat, it may be distinctly more than the time-cost of cooking for yourself. (Though, again, you can do other things while you wait for your food.)
I am not accusing you or Academian (or anyone in particular) of making this mistake, but: Beware of simple-minded time/money tradeoff analysis where you assume the value of your time equals (or even is well approximated by) the amount you are paid. That's a safe assumption if you actually have the option of adjusting your working hours ad lib and your behaviour is perfectly consistent, but not otherwise. (I could save myself some time by not cooking. I am paid quite well. But since I'm paid an annual salary rather than an hourly wage, I can't simply spend less time cooking and more time working and get more money at the same rate as I'm paid at.)
Cooking for yourself may well get you a healthier diet; you need to consider how you value your health as well as how you value your time.
I'm quite sure there are plenty of people for whom cooking isn't a good use of their time, but I suspect there are fewer such people than a simple comparison of costs with pay rates would suggest.
In average; but it also depends on what you cook for them or where you take them.
